Donovan: /* Current objectives */

==Introduction==
My name is Donovan Jones. I am a software developer from New Zealand. I am a competent wiki editor and plan to assist the OSE in this capacity. I do not plan to collaborate or assist in other ways in the medium term. Essentially I am a [http://en.wikipedia.org/wiki/Wikipedia:WikiGnome WikiGnome], as such it is probably safe to ignore me.

If you don't like some of my edits please let me know on my talk page, I don't want to step on any toes, but I'm not going to seek approval for every edit. On aggregate I hope you will agree I am improving the wiki, so let me know when you feel I am not.

==Current objectives==
* '''MJ request''' - [[How_to_Create_Frames_and_Windows_in_Media_Wiki]] for [[Flashy XM]], [[Flash Mob]], and other pages.
** I investigated support for widgets on OSE wiki, I was wanting to try: http://www.mediawikiwidgets.org/Iframe
** I do not have permission to edit pages in the Widget namespace. So cannot try out this widget on the OSE wiki.
* Fix broken links to [http://opensourceecology.org/w/index.php?title=Special%3ASearch&search=openfarmtech.org&fulltext=Search openfarmtech.org].
* [[Wiki_instructions#Style_Guidelines|Improve metric support]] on the wiki.
* Work on [[Work_Log_Guidelines]] particularly the [[Date_Format_Convention]].
* Work on and improve [[Special:Categories|categories]].
* Wikifying pages: work on wiki linking.
* General grammar and spelling fixes.

==Future objectives==
* Collaborate with my father to contribute on Biofuels particularly [[butanol]].
* Creating custom wiki templates
* Creating custom OSE infoboxes
** keep any eye on http://meta.wikimedia.org/wiki/Wikidata which will make creating infoboxes much easier.
** software infobox to include:
*** licence
*** ubuntu package name

==Thoughts==
As an outsider there are a few observations I would make about things that could be improved.

===Support for the Metric System===
Three countries use non-metric measurement systems: Liberia, Myanmar, and the United States. I believe for OSE to a have a global impact it needs better support for the metric system. Many collaborators will only be able to source metric parts. I want to help provide better metric support at least on the wiki.
====Using Conversion Templates====
Complex conversion templates are available from other media wiki sites eg: http://en.wikiversity.org/wiki/Template:Convert. This system is very comprehensive http://en.wikiversity.org/wiki/Template:Convert/list_of_units but is quite complex and requires subtemplates. I have done a proof of concept with temperature conversion:

* <nowiki>{{convert|60|°F|°C|sigfig=3}}</nowiki> = {{convert|60|°F|°C|sigfig=3}}
* <nowiki>{{convert|16|°C|°F|sigfig=3}}</nowiki> = {{convert|16|°C|°F|sigfig=3}}

If OSE wish to use these templates I suggest following the instructions at http://www.mediawiki.org/wiki/Help:Templates#Copying_from_one_wiki_to_another, this will be much easier for someone with import rights on the OSE wiki (I do not have these rights). Without import rights each subtemplate needs to be copied manually which is tedious and is prone to cut and paste errors.

===Wiki standards===
Standards like the [[Date_Format_Convention]] are important in a wiki, they create consistency, help define a framework within which people can become more productive and in general help to make the wiki more functional. As such I will be editing peoples Logs, please let me know if you would prefer I left them alone.

===Date formats===
I have a definite opinion about what the best date format is but I will not be converting dates to this format or pushing this other than recommending it here.

The best date format is the [http://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format. It looks like this: '''2012-11-27''', compare this to '''02/04/03''' which has three possible interpretations.

The reasons it is best are:

* it is unambiguous.
* it sorts correctly using string or numeric sorting.
* it is a formal standard.
* it is widely used.
* the format can also be used to represent precise date and time, with timezone information.

see also: http://www.w3.org/QA/Tips/iso-date

==Other Skills==
I do have some other skills that may be useful to the OSE. I am an experienced data munger, if you need scripts written to process and convert data feel free to drop me a line. Things like

* Writing cron jobs
* Talking to databases (postgres/mysql/sqlite)
* Pulling in xml,yaml,json,html,csv,wiki markup
* Spitting out xml,yaml,json,html,csv,wiki markup
* Talking to REST web services.
* Screen scraping and web automation.

My language of choice is perl. My collaboration method of choice is [https://github.com/donovan github]. My development environment of choice is ubuntu. My server environment of choice is ubuntu/debian.

=Steps=

*Using the tin snips, cut the sleeve of the telephone wire by 5cm and 20cm at both ends. The cutting tolerance is 2cm.

*Using the tin snips, cut the orange-white wire at both ends of the telephone wire.

*Using the wire strippers, strip the bluewhite, blue, and orange wires of the telephone wire by 2cm at the 5cm end and by 1cm at the 20cm end. The stripping tolerance is 0.5cm.

*Insert 3cm shrinktubing into the 5cm blue, blue-white, and orange wires.

*Bend the sensor prongs and the exposed metal of the 5cm wires into hooks such that the 3 prong hooks can latch onto the 3 wire hooks to facilitate soldering. Use pliers to pinch the hook connections during the soldering process.

*Using the soldering set and the helping hand, solder the hall-effect sensor prongs to the 5cm wires. The orientation of the soldering connections is such that, when you can see the sensor text and its prongs pointing downward, from left to right the colour of the wires to be soldered are: bluewhite (for 5V+), blue (for GND), and orange (for Signal).

*Using the heat gun, cover the soldered prong-to-wire connections with the shrinktubing then apply heat to the now-covered connections. The shrinktubing should shrink, forming a tight insulating seal for each of the prong-to-wire connections.

*Insert the wired hall-effect sensor into the PVC tube leaving 2cm of space at the non-insertion end of the tube.

*Pour the silicone into the tube such that the tube is completely filled in.

*Mark the sensor tube side that denotes the flat side of the Hall Effect Sensor (side with writing) with a line

*Gently set the sensor unit with the wire end down and wait 24 hours for the potting compound to cure.

Donovan: /* Chuck Harrison Torch Table Training */

= [[Chuck_Log|Chuck Harrison]] Torch Table Training =
I signed up for a class offered local to me (Seattle) by [http://www.allmetalarts.org/ Rusty Oliver]. First session 27-Nov-2012.

Rusty has a 5x10 ft Torchmate table with a Hypertherm PowerMax 1000 plasma cutter good for about 60 amps. It cuts 3/8-in comfortably and struggles with 1/2-in steel.

Notes:
* Plasma cutting takes a lot of compressed air, count on a 3-5 hp compressor with a 60 gal tank.
* Moist air cuts down lifetime of the consumables (torch electrode parts) dramatically. Use filter-driers.
* Torch height is critical to good cut quality. 1/8-1/4 inch is typical.
* Rusty has a Torchmate automatic height control Z axis but it has not been very effective. Tends to hunt up and down
** Z axis is a servo (not stepper), which means it can sense stall via motor current
** To find part surface prior to striking arc, Z axis drives torch down until it hits part, then backs up
** During cutting, Z axis is controlled to maintain a desired arc voltage
** Different standoff heights are used for piercing and subsequent cutting.
** Automatic height control is a separate module (not part of the PC-based software) with several programmable parameters
* Torchmate software provides basic 2D drawing capability, tool path generation (kerf allowance), import DXF, svg. Generates and executes G code. Many features I have not learned about yet. [http://www.architecture.yale.edu/dmonline/Tutorials/cnc-plasma/Plasma-Cutter.pdf Tutorial] from Yale, [https://www.google.com/search?domains=fab.cba.mit.edu&sitesearch=fab.cba.mit.edu&btnG=search+fab&q=torchmate MIT].
* Cut quality is worse than I expected. Lots of dross and several degrees bevel in ~3/16-inch thick steel. From manufacturer videos I think it can be done better.
* There are problems with torch cutting bolt holes. Piercing is hard on the torch (wears out consumables). The hole is tapered, may not be perfectly round, and can't be easily drilled out because of the hardened heat-affected-zone left by the torch. Not impossible, just not easy.

Donovan: /* Tue December 4, 2012 */

=Tue December 4, 2012=
Good day of consistent work. Yesterday's preparation payed off. Was able to record usabilty test with Matt at high quality. Took really long time to encode video and upload, but it's a good start and shows that remote usability testing is possible (lots of tweaks ahead, though). Aggregated info from 3 usability sessions into a single document ([https://docs.google.com/document/pub?id=1Ux-bpFeAXpe8Oa5eTy1CbuqwX_88aYbqSixjvNEylMI Usability Report 1]) and created a plan for beta release ([https://docs.google.com/document/pub?id=148iS4qeIIjdlluvjZrHotRwj41OnH5RIjK2db6ucqJc Beta Release Requirements]). Given the testing so far, I think that twitter integration is of lower priority than brainstorming or teleprompting features. Also I face a relatively volatile task of created reworked pages for links off of video viewing pages - this has to be looked into soon, so that I can gauge what this means in terms of release date. I originally anticipated that a single person was responsible for website promotions and that there would be some sort of help in rebuilding the information that video viewers would be directed to. That this is not true and that I could potentially be facing website redesign that could spiral into more work needs to be mitigated by finding some minimum amount of adequate work. However the quality of the app is dependent upon this information being high quality. I'll need to investigate this more tomorrow. Also, helped Parker and Tristan deconstruct power cube for decon/recon video. Nice to get more contact with power cube. Updated [[True Fans Mircofunding App]] wiki page.

Tuesday Goals: Test with Matt (success), uploaded video + usability report (sucess), no work on usability update (failed) - decided to work more on strategy today rather than code. I want to reevaluate schedule tomorrow and see what I'm on track based on what features I can add. This should pressure me to decide what adds real value to the app rather than looks like shiny delicious programming/design endeavour.

Wednesday Goals: Estimate feature to release time payoff for outstanding work and knock down 2 Show Stopper grade issues (see [https://docs.google.com/document/pub?id=148iS4qeIIjdlluvjZrHotRwj41OnH5RIjK2db6ucqJc Beta Release Requirements] for examples).

Week 3 Goals: Try to get FeF True Fan videos after Friday meeting (hopefully team will be in high spirits) during the weekend. Clean up all high priority bugs and clean up all easy usability paper cuts with at least some solution (focus getting a solution rather than pursuing the optimal solution). I no longer consider Twitter integration to be a realease feature. Revising existing pages so that the correct information flows exists now has a much higher priority.

=Mon December 3, 2012=
Slept short in attempt to getting sleep scheduled more aligned with daylight. Got Yoonseo to do usability test over skype and discovered lots of probelms with recording skype voice + video. Although recordmydesktop works quite well in stock Ubuntu, Kubuntu (and thus KDE) does not come with a work pulseaudio (everything appears to alsa) making it impossible for multiple applications to share an audio stream. Several hours were spent debugging this (this is a tough problem to fix--integration level issue with many possible solutions and dead ends). Was able to cook dinner within a reasonable time frame and with non-trivial leftovers. Made a potato-leek-tofu stew. One of the best things I've cooked so far. Extra clean kitchen helped things along and cooking stew in a big pot minimized dish usage (able to clean all dishes before serving). Served pretty much on time too :). Was able to finish debugging recording issues after dinner (basic solution: install pulseaudio and gnome-media (sound recorder), start pulseaudio, reconfigure phonon audio hardware in system settings, use pavucontrol to pipe internal soundcard into sound recorder, then do recordmydesktop on skype -- checking levels in pavucontrol to make sure everything is working...not fun but excellent result that records mic sound and computer sound). Set up remote user test with Matt for tomorrow at 1pm. Took notes on Parker test and Yoonseo test. Basic issues - ambiguity of 'Upload' and 'Save Video' and unobvious difference between quotation message and personal friend message. Need to tweak instructions and prevent people from clicking 'Save Video' before uploading. Will try to add this before test with Matt, but 50-50 that that's actually possible. This was one of the first days where all aspects of time were basically accounted for (although recordmydesktop-skype-pulseaudio was a standard unpredictable time sink).

Tuesday Goals: User test with Matt - recorded + notes and work on usability update 2; bonus points: look in to playlisting. No cooking tomorrow, so there should be lots of time.

=Sun December 2, 2012=
(Writing on Monday) Warm again. Pretty relaxing day, or at least started so. More contract and org talk in hablab. Played Settler's of Catan and then taught Yoonseo and Gabi Tichu. Offered to deliver diagrams/papers to Marcin. Left at 7pm and met Kavitha in Kearney. Very foggy again, but I knew the route better. returned to Hablab around 9:30. No time for remote testing and Tristan was sleeping, so I couldn't do local user test either. Yoonseo gave me an intro to the Arduino. Tried to think of interesting ways to make the led blink--made a program to interatively "discover prime numbers by blinking on potential primes and and not blinking otherwise. Very fun. Looking forward to doing more work with Arduino. Have CEB code to look at. Got very OCD at night and started organizing things like mad. Hablab kitchen is much much cleaner. Improved living room and bathroom too. Did all of the dishes.

Sunday goals: successful relaxation. Probably could've hassled other FeFers for a test but relaxation was probably worth it. Trip to Kearney cost about 3 hours ish. Probably would've coded else.

=Sat December 1, 2012=
Strange warm day. Organizational structure talks continue. Aaron had me change main website -- now have basic knowledge of web administration system the site is based on and basic understanding of home page implementation (php templating). Cold hands again due to lack of sun. Cleaned up pallets behind hablab, folded up a couple stray pieces of tarp, and pulled brick rollers out of ditch. Conducted first usability test with Parker and created a video of it (about 20 minutes). Considering putting it up on the wiki as documentation. Made a Walmart run for wider range of foods and basic goods (head lamp, hooks, and safety glasses). Extremely foggy night had to drive slow and missed turns multiple times. Got lots of tofu, egg noodles, canned goods...should be able to avoid any grocery runs before cooking now. Unable to do laundry because I couldn't find laundromat (nearly impossible to read street signs in the fog).

Saturday goals: 2x usability tests - completed 1. Not really able to peel off Gabi or Yoonseo who were busy looking into contracts. Not really much I could do about it -- should be easy to remedy tomorrow. Code cleanup on facebook.js -- didn't get to. Contract distractions and website diversion from Aaron burnt that time (which wasn't wasted time, just not accounted for as planned). Didn't get to bonus remote usability test. I would like to do a practice test through skype at FeF before doing a remote one -- really don't want to waste a volunteer's time.

Sunday goals: 1 FeF usability test over skype. 1 remote test. Relax. Feeling bored: clean up facebook.js

=Fri November 30, 2012=
Moved desk into living room between stove and window. Big improvement in hand comfort. Natural light is additional plus. Spent some time responding to message about collaborative production run situation. Before dinner figured out how to login once to facebook. Took longer than expected due to ambiguous documentation (always a problem with facebook). Wasn't able to debug code due to rare github outage (considered uploading direct to webserver, but didn't think it was worth the effort). Pivoted to watching Steve Krug's example usability test video. Very helpful. Downloaded example script. Sent email to two usability test volunteers. Cooked dinner. Wheat spaghetti, hash browns, and spinach salad (prepped by Gabi) with shallot and clementine dressing. Hash browns took way way too long. Attempted to boil and flash fry but boiling took a long time and so did flash frying. I should probably avoid potatoes if I want to cook quickly. Also trying to boil shredded potatoes is somewhat hopeless due to starch in the water (or at least hopeless to strain). Going to cook dal with rice next time. Hopefully I can get the cook time down to an hour--perhaps I can start early. Night time work session went pretty smooth. Was able to write entire usability script (link attached) and do some debugging on facebook.js. Interface is stable and ready to test, but more debugging is certainly necessary. Yesterday goals: code cleanup - partially successful; message sending usability improvements - partially successful; usability interview script - successful (but after dinner); cook dinner in 1 hour or less - abject failure due to hash browns (other parts were ready at 7). The time in the morning spent on communications (mine and talking with others) bit out about 1.5 hours. Poor FB docs and github outage also cost me (although poor facebook docs was already a known factor). Still need more discipline on cooking and also more options for food. Plan to go to Cameron in coming days and get some tofu + various other important goods to increase cooking options. Goals for Saturday: 2x hallway usability tests with FeFers and code cleanup in facebook.js. Bonus points: 1 remote usability test.

=Thur November 29, 2012=
Awoke refreshed. New person on the couch in Hablab - Colby. No scrum and uncordinated Hablab team. Beautiful day. Colby seems to have helped cool things down. Intermittent programming during the day led to intermittent but steady progress. Bad circulation + cold hablab has to be delt with. Need some thin gloves with the finger tips cutout. Glass desktop is also suboptimal given the hablab temp. Kavitha made dinner, and talked with Colby and Parker extensively about company structure which seemed really helpful and enlightening. Would like to download Colby's brain... Able to pop back in and solve a couple issues before sleep. Message sending interface is nearly finished and my head's clear. Gonna smooth out a couple usability inconveniences tomorrow (facebook only logs in once!), and then pivot to remote usability testing. Maybe I can snag a Factor E Farmer for a quick hallway usability test or 2 tomorrow. Right now I'm about 2 days behind schedule. Since there's no production run this weekend I think I can reclaim one of those days, but I have to be cautious and not work too hard and burnout. Friday goals--code cleanup, message sending usability improvements, and usability interview scripts before dinner. Cook dinner in 1 hour or less, and then plan out remote usability testing as best I can.

=Wed November 28, 2012=
(Writing in retrospect.) This was my absolute worst day in terms of progress. Suffering from low motivation and constant interruption. Made some progress to finishing submission interface, but unable to concentrate. gChat with Kavitha and and food run cut evening very short (work stopped at around 4pm). Cooking, meeting, and dishes took the rest of the night. Meeting seem to start okay but ended poorly. Extremely glad to see Kavitha. Low motivation. Went to bed early.

'''Week 2'''

=Tue November 27, 2012=
(Writing in retrospect.) Before dinner work made good progress and finished the unified message input interface to a point of satisfacion. After dinner meeting to discuss Collaborative Production Runs went poorly and sent Hablab team into disarray. Night time development period was spent discussing a way to resolve issues. Unable to refocus and return to development.

=Mon November 26, 2012=
Rose decently early and added to scrum questions (how do we change stuff on website, do we need approval to change stuff, can we earmark True Fans funds, can people make videos for the True Fans app and what is the tone of the videos that they'd like to make...). Created a good plan for coding the facebook interface. Had scrum meeting but wasn't able to ask questions due to infrastructure priorities. Worked outside on insulation apron for about an hour and a half. Then went in to start coding at about 3pm. Designed a quality unified interface for facebook and email (thinking of moving twitter to a different step). 5pm started the dinner process--found a good recipe for spicy peanut noodles and went to Dungy's with Tristan to get extra ingredients. Tristan split the food tab ($30 - $15 each) with me. Egg noodles cook fast and was able to finish cooing by around 7:15. Did the dishes afterwards (bad choice--took way too much time). Started coding again at 9pm. About half done with unified interface. I expect 1 more full day of coding and facebook integration should be mostly complete (although I may forgo posting actions for now as it might be technically challenging to change the meta tags of a wiki page...). Goal is to finish facebook integration tomorrow, write user testing scripts and do 'hallway' testing on Wednesday, and do remote user tests on Thursday. Considering pushing twitter integration to post-release and freezing the features after I get play lists working. I'm concerned that I going to get tied up redesigning various pages that our video landing pages link to. It doesn't seem that responsibility for the content of webpages clearly rests in any one persons hands. This should change.

=Sun November 25, 2012=
Rest day. Slept in a bit and went to a cafe in Cameron with FeFers. Walked around the farm and tried to gage most important tasks still unfinished. Talked to Parker about True Fans plans. Went on a run for fire wood that ended up being a fiasco and took up a lot of time (but on the bright side was kind of good team building expereince). Wrote up some questions for scrum meeting on Monday.

=Sat November 24, 2012=
Collaborative Production Run Day 2. Worked on aligning primary and secondary and secondary arms of frame. Problems with documentation lead to retorching the holes. Lots of band saw cutting. Lots of lifting and moving things. Worked on one of the vertical plates in the compression chamber. Swept out half of the workshop.

=Fri November 23, 2012=
Collaborative Production Run Day 1. Setup welder. Did lots of grinding on hopper and primary arms. Hole punched box alignment pieces. Ran band saw and iron worker. Did some mag drilling. Welded u channel nuts on u-channel.

=Thur November 22, 2012=
Beautiful day -- tidied up a bit in front of hablab (organized pallets, wood, irrigation hose) and started to grade area for insulation apron. Kavitha made an excellent Thanksgiving dinner. True Fans App: More feedback emails (BTC and another testing volunteer - Emily). Started facebook integration. Made slightly less progress than hoped but preliminary integration is up on test server--need to create an interface now. Need to do some backend work to generate adequate meta tags for facebook actions. I expect facebook integration to take one more day, but I could easily hit a snag on the meta tags so I'd plan a day and a half +/- half a day. Afterwards: 1) scripts/teleprompting, 2) twitter, and 3) playlists.

=Wed November 21, 2012=
Met with Marcin. Attended team meeting. Toured farm (extra work oppurtunities-insulation apron and light screen). Made dinner (spinach potatoes with rice made by Kavitha). True Fans App: sent some feedback emails (to Chuck and Matt). Usability improvements -- upload page no longer has optional inputs visible by default, it's impossible to double submit the form, and changed viewing location of status messages on upload page. Plan to work on facebook integration tomorrow.

=Tues November 20, 2012=
Arrived at FeF. No issues driving. Set up room and ready to go. Meeting tomorrow with Marcin.

=Going to Github Website=

[https://github.com/ Click Here]

[[Image: github.jpg|200px]]

=Make SSH Key=

ssh-keygen

Go to github account settings.

Go to SSH Keys

Copy and Paste the SSH Key starting with ssh-rsa or similar.

When prompted, enter your github password.

=Cloning a Repository to a Folder in Your Computer; Pushing your Files to the Repository on Github=

Remember to always navigate to your computer's directory that contains the git files.

When prompted in the instructional in the below link, enter your SSH Password

http://myprogrammingblog.com/2012/01/20/github-how-clone-github-repo-how-to-push-to-github-how-to-get-files-from-github-ubuntu/

When pushing, make sure your local files are fast-forwarded to the latest repository files. You can do this by pulling the repository:

git pull

=Checking your Website=

Type in your web browser the path to your website files on your computer. Example:

file:///home/user/teambootstrap/teambootstrap/index.html

=Using github as a file archive without a local clone repository=
Sometimes you want to get to one or two OSE project files that are stored on github, but you don't need a complete local copy of the repository.
* Usually you can navigate to the file, open it, and click on the "raw" button at upper right of the viewing pane. (''Don't'' try right-clicking and "save link as" back in the project directory tree; you'll get a fistfull of html.)
* For text files, the "raw" button is likely to display the unformatted text on screen rather than automatically starting a download. However, you can use your browser's "save page as" function from here.
* Alternatively, use the "download zip" button on the main project page. This will download a zip archive of all the current files. Use an archive manager to extract the specific files you want.

Note that text-file line endings are operating-system dependent (different variants for linux, Mac, and Windows). Different download methods may use different line-ending conventions.

The example on that page will show you how to use CAD with circuit schematics made with [[Eagle]], the CAD Bill-of-Materials (BOM) IO module, and the CAD Digikey and Mouser Fetch modules. Specifically, it covers:

* Generating a BOM from Eagle for the first time.
* Automatically filling description, manufacturer as well as pricing information from Digikey and Mouser, with a configurable preference.
* Generating order sheets with a user-defined quantity multiplier that can be uploaded directly to Digikey and Mouser.
* Filtering Eagle footprint names.
* Resolving the conflicts generated when the Eagle schematic and the BOM disagree.

CAD Model Transfer Process

Donovan:

=Sketchup to CAD=
==Discussion==
===From [http://www.designcad.com.au/drupal/sites/default/files/export_models.pdf DesignCAD.com]:===
*If you have used SketchUp, you know that it works all the time in the 3D environment unless you tell it otherwise. SketchUp encourages you to build your model in perspective mode and to apply materials to surfaces as you go. Despite this level of sophistication, SketchUp still operates very quickly, even on fairly modest computer equipment - there is no noticeable deterioration in performance as you add new parts to the model.
**SketchUp can do this because it builds its models using triangular meshes; many surveying packages do the same when they are asked to create terrain models of land surfaces. Complex 3D entities such as Coons patches, surfaces of revolution and so on which are used by software such as AutoCAD, IntelliCAD and MicroStation are not used.

*This fundamental difference in storing model geometry places severe limitations on the model when it arrives in the CAD environment. The figure below shows the warehouse model above in the AutoCAD environment after we had exploded it and selected one of the faces. Note the appearance of many triangles. Incidentally, AutoCAD translates these triangles to to 3DFACES.
**<b>To See Figure Below, Click Link Above to Source and go to Page. 4</b>
*To sum up, we suggest that movement of models should be towards SketchUp from your CAD software, not the other way around.
==Possible Solutions==
===Open Source and/or Free===
Insert here if found. A tentative process for transferring 3D CAD Models between different platforms would be through [http://usa.autodesk.com/adsk/servlet/pc/item?id=10775855&siteID=123112 Autodesk's free FBX Converter]. This needs to be investigated however.
===Paid and/or Proprietary===
[http://www.sycode.com/products/skp_import_iv/index.htm SKP Import] for Inventor creates trimmed planar surfaces for each triangle/quad and knits them together to create a body. If the polygon mesh is closed (i.e. it does not contain boundary edges) then SKP Import for Inventor will create a closed body feature, otherwise an open surface will be created.
*Downside:
**Costs $249 for single non-updateable version, $299 for subscription ($50/yr after first year), which includes updates for new versions of Inventor.
**Not open-source or super distributable to the "144 Seeds" -- but then again, neither is AutoCAD Inventor.
*Upside:
**We only need one license to bring all the Sketchup files created by the masses into CAD. i.e. any collaborator with a great design could send us the Sketch-up file and we'd be able to turn it into a professional CAD file with our one license.
**Converted files could then be distributed in CAD format to the masses with drawings, models and all the rest (as well as the source version built in Sketchup).
**Simple and easy to use.

Open Hardware is an emerging field, and it will be a standard feature of the open source economy. The most fundamental level of open hardware is open materials - the very substances that things are made of - and therefore are the last frontier for human freedom. Open Materials is a platform to make this happen. By raplacing scarce materials with common ones, we can make resource conflicts a thing of the past. Open Materials can contribute to this. My critique: platform appears to focus on smart materials rather than materials in general.

Recruit software developer to analyze FreeCAD and build with/upon their work. Short-term Objective: Get Assembly Module Working.

Ok, first FreeCAD:

As they say themselves, it is still in the early stages of
development. I (Conor) have searched for documentation, and apart from the
getstarted [http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Getting_started]
there are 2 nice articles from December (so version 0.9, which btw. is
in Lucid already). The funny thing is that for some reason, both are
in... Polish! I understand you have polish origins, so maybe you speak
Polish. Otherwise just google translate. They give you examples and a
better idea of what it is right now capable of.

Blender a bit longer, and try FreeCAD again when version 0.11 or 0.12
comes out.

==October 12, 2012==

I'll take on the Arduino analysis to determine how much function we can compress into the arduino. Feedback is my primary concern along these lines- I'll check both out.

I guess we're still indetermined on whether to go buck/boost converter or transformer. I prefer buck/boost but we need more research about sourcing and fabrication along both lines at this point.

As for the power handling circuit, I assume we can establish H-bridge because we are working with high power specifications.

Then there is the filter. Start off with LC lowpass I assume?

And of course, the DC-DC step-down and regulator circuits for the logic (ex. 5V, 3.3V).

And that should be all of the systems we need to work with.

Best,

Yoonseo

I remember finding that exact same webpage some months ago. With the signal that code produces, couldn't we use it with one or two modifications to produce the MOSFET drive signal? Compare the upper waveform of this http://interface.khm.de/wp-content/uploads/2009/12/ddd_title.jpg to what's shown on page 26 of this: http://www.wpi.edu/Pubs/E-project/Available/E-project-042507-092653/unrestricted/MQP_D_1_2.pdf I may be over simplifying, but couldn't we integrate the code for 50 / 60hz operation and some of the feedback into the micro-controller as well? Device protection and HMI would need to be done through a separate controller but I think it should work.

I'm beginning to see your point, a solid state DC/DC buck/boost regulator would provide greater versatility and ease of fabrication compared to a custom transformer. My concern is how complicated the design will be with the power level we're dealing with, it will almost need to be a project unto itself. Here's an example of what someone else went through with a similar converter and power level. http://www.stevehv.4hv.org/boost_converter.htm

"I assume the feedback circuit would involve an output error that goes through a PID loop to affect the amplitude factor of the sine wave amplifier circuit?" - I agree.

~Matt

----

Regarding the digital sine wave generator, I am open to using either an Arduino or an IC. At the relatively low frequencies we need (~60Hz) I think distortion will be a non-issue. For modularity (microcontroller board) and versatility (we can readily change the frequency) , I am leaning toward the Arduino using direct digital synthesis as explained here [ http://interface.khm.de/index.php/lab/experiments/arduino-dds-sinewave-generator/ ] with available code and <1% harmonic distortion for our frequency range. Alternatively, we could use an IC but I was unable to find ones with low enough frequency ranges, so I have sourcing concerns. Thoughts?

Regarding the pulse width modulator IC, the immediate concerns that come to mind are integration with the feedback circuit. I checked the SG3524 datasheet and it appears we would have difficulty working within the constraints of the IC- ex. discrete circuit necessary for the oscillator Rt and Ct pins in order to produce a PWM sine wave. I'm thinking alone the same lines as you- too high level and limiting.

Buck/Boost converter vs Transformer - For versatility, I started leaning towards the buck/boost converter, and given that a DIY transformer now sounds relatively difficult to fabricate, I'm leaning more towards the buck-boost converter design pathway (albeit with higher filter complexity). Additional research/information might clarify things.

I assume the feedback circuit would involve an output error that goes through a PID loop to affect the amplitude factor of the sine wave amplifier circuit?

Cheers,

Yoonseo

==October 10, 2012==
'''Email Exchanges'''

Aaron - no problem.

Yoonseo - I think we both agree using a digital sine wave generator is the way to go. I've seen it done with an ardiuno and i'm sure something simpler exist's on an IC.

Another possibility is to use a pulse width modulator IC. Texas Instruments designs a few, the SG3524 being one example. It's cheap and would simplify the design, however, I think something like this might be too high level and pre-packaged. The same argument could be made for the digital reference signal but I think the increase in build quality is worth it. Thoughts?

Buck/Boost versus Transformer: Component sourcing should be the same level of difficulty for both, I've managed to find sources for the electrical steel and magnet wire as well as the buck/boost converter main components. Although I'm curious about the cost's of each, I'll have to look into that more. I think fabrication is going to prove more difficult with a DIY Transformer, this would require either manually winding the bobbins or constructing a coil winder that can handle #4 to #10 wire and maybe some tooling to accurately punch out the laminations.

Have a good one,
Matt

Sergio,

We'd like to invite you to join this email discussion about building the open source power inverter with Open Source Ecology? If you reply to this thread, please reply to all.

Everyone, this was our last correspondence with Sergio:

Hi Aaron, Vann,

Thanks so much for your email, sounds like a fun project.

I have limited experience in this type power electronics; while I’m familiar with UPS systems which, in principal work similar to aninverter like the one you describe I wouldn’t be able to build one myself without spending some time doing research. The information in the wiki page may not be sufficient.

This is an ambitious project and may require more than just one person to complete. The reality though is that, these types of devices require several circuits within, some of which I can design faster than others.

I would like to help, but I wouldn’t be able to do this on my own. Also, I wouldn’t be able to start before September.

Please let me know if this is useful.

Kind regards

Device protection and HMI would need to be done through a separate controller but I think it should work.

I'm beginning to see your point, a solid state DC/DC buck/boost regulator would provide greater versatility and ease of fabrication compared to a custom transformer. My concern is how complicated the design will be with the power level we're dealing with, it will almost need to be a project unto itself. Here's an example of what someone else went through with a similar converter and power level. http://www.stevehv.4hv.org/boost_converter.htm

"I assume the feedback circuit would involve an output error that goes through a PID loop to affect the amplitude factor of the sine wave amplifier circuit?"
- I agree.

Good Evening Everyone,

I have a few questions regarding the inverter oscillator design and high voltage DC regulation.

Oscillator - I'm looking through Yoonseo's design [ http://opensourceecology.org/wiki/Inverter/Yoonseo_Design ] is the use of the Bubba oscillator set in stone? I'm reading through the WPI project report and it appears they had a good deal of trouble with it's operation. Would it be possible to go with a fully digital reference sine wave? Has there been any more development on the reference wave feedback control circuit? http://opensourceecology.org/wiki/File:06_Feedback_Circuit.jpg

DC regulation - With the need to accept a wide range of source voltages and output a consistent 120 / 220 VAC signal, has there been any thought into the need for a high powered buck / boost converter to acquire the needed 170 / 311 VDC? Another possibility is to use a multi-tap output transformer, I would be in favor of this route for the following reasons:
1. Reduces the complexity of the output filter
2. Can be designed to replace the high powered buck / boost converter and therefore improving reliability by simplifying the over all circuit.
3. In the case of a shorted MOSFET or some other fault, will eliminate the possibility of high voltage DC present on the output signal
4. Output transformer can be be manufactured given a well made sheet metal press, various hardware and proper research
See this instructables link for a reference on a transformer coupled design: http://www.instructables.com/id/250-to-5000-watts-PWM-DCAC-220V-Power-Inverter/

Also, in regards to the failing inverters already in place at FeF, has any effort been put into investigating the possibility of repair? If these are preventing collaborative production runs of the GVCS it may be faster to fix them in the mean time until this project is completed. Aaron, if you're open to the idea, would it be possible to send one of the failed units to Denver so I could have a look at one?

Have a good night,
Matt

Hello Everyone

Does the inverter need to be grid tie now or in the future?

Tim Boyd
tboydlaser@aol.com
----
The circuit for generating the reference sine wave is not set in stone. I prefer a fully digital reference sine wave in preparation for versatile operation. If we pursue the digital generation I assume we would just source the relevant integrated circuit?

No development on the feedback circuit to date.

Buck/boost converter considered, but not developed to date. Between the buck/boost converter and the multi-tap transformer, I am most concerned about ease of fabrication/sourcing and would like more information regarding that factor.

Best,

Yoonseo

CNC Torch Table Log

Donovan: /* Oct. 2, 2012 */

==Oct. 21, 2012==
This project is beyond my electronics knowledge. But when i was planning on building a Plaz table a while back from a kit my research concluded that CandCNC.com was the best way to go. I've been following his message board for a couple years and all his end users are very happy and amazed at the quality and low cost. His digital torch height control really seems to be impressive an unmatched for less then 10x the $. You don't have to have torch height control to get started cutting, but you have to plan for it because you quickly decide its a necessity. I have one of his 5 axis servo kits waiting until i have more room for a table, if you have any questions just ask. And if you decide to put an oxyfuel torch on it i have some machine-style torches and regulators you can have. Keep up the awesome progress. -LoadTest

I love this idea,

Static compensation would be easy enough to map out deviance and do a best fit approximation between start and end of each line. Dynamic compensation would be a little more involved; only if someone had a line on cheap linear scales. What are your thoughts on where this compensation is performed? If it is done on the PC side you would have a lot more move commands to transmit; a lot of little slightly adjusted lines making up the one long line. If it is done on the Arduino that wouldn't be a problem, but I question the muscle of the atmel uController. What were you thinking about methods of implementing this?

Cheers,

Darren

I'd be interested to see the torch table serve a second purpose as a
layout & marking tool.

There are plenty of metal parts that involve classic layout techniques
like machinist's square, scribe, center punch, and steel measuring
tape. With just one or two tools (e.g. a scribe and a spot drill)
mounted on the XYZ table we could automate a lot of this.

I have seen the accuracy of the torch table spec'd at 1/32 inch, but I
think we can do better, especially if we calibrate it and incorporate
software compensation for machine structural inaccuracy. I think
0.005-0.010 may be achievable.

A very useful addition (for both standard torch cutting and for an
automatic layout tool) would be a rugged touch probe that can be used
to pick up the edges of a part. Clever code should take a part that is
not laid square on the bed and rotate the coordinate system to match
it.

One bottom line is to make sure the tool (torch) mount is a nice
modular interface. Which I suspect it is, though I haven't seen the
pictures yet.

Thoughts?

Starting to cook here, check the video:

<html>
<iframe width="420" height="315" src="https://www.youtube.com/embed//ZY9TiVzhfO8" frameborder="0" allowfullscreen></iframe>
</html>

This sounds better after changing to the series winding connection on
the X steppers.

Important request to Darren

Please connect the X2 AND gate in the *step* line, not the *enable*
line. I found that gating the enable causes the X2 motor to jump up to
a half-step (8 microsteps) between enabled/disabled conditions, which
wreaks havoc with the X1-X2 homing action.

Alpha-quality code is at https://github.com/chuck-h/grbl .

==Oct. 13, 2012==

'''Chuck'''

Hi Darren,

I've got an X1-X2 test bed now! I have to make a cut/jumper on the
interface board so I can independently enable X2, then I can work up
some new grbl homing code.

http://opensourceecology.org/wiki/CNC_Torch_Table_Control_Overview#Test_mule

I am getting quite a bit of noise, the microstepping doesn't seem
perfectly even. I should try with different current levels.

Possible issue: grbl seems to disable the drivers at the end of a
move, which will cause the stepper to drop into its nearest magnetic
detent. When drivers are re-enabled I believe we should pull back into
the previous microstep location, but I think there is a potential for
losing position with this logic if we happen to stop at an ambiguous
phase. I am going to check whether I see this problem. Any way
steppernug could go to "idle current level" instead of full shutdown?

==Oct. 5, 2012==

'''Yoonseo'''

Control for torch and plasma cutter- digital high to activate relay would suffice.

Z axis should operate the same as the X and Y axes (move in response to interpreted gcode). For incremental dev's sake, I think we can table the arc voltage feedback.

Start-of-cut should be based on the gcode CAM prep, yup. For versatility's sake. Vann has previously made some gcode edit code that revises the gcode file for oxyacetylene cutting. http://opensourceecology.org/wiki/Gcode_Preheat

Gctrl is a GUI gcode streamer/jogger/homer already out there, so i think we're good on this part. http://opensourceecology.org/wiki/Gctrl

Will get you picture soon. Smartphone is having issues charging.

Oh- also, I'd love to get the details on how to modify the GRBL code for other project purposes- the challenge is getting the intention correctly mapped to the right change. Ex. how to change which pins are for which step/dir for which axes.

Cheers,

Yoonseo

'''Chuck'''

This would drive an off-board SSR? Or should we put a heavier duty
driver on board (e.g. open drain power mosfet)?

Any need for regulated 12V to come off the board?

BTW I was thinking 24/28V for motor supply, what about you?

Cheers,

Chuck

==Oct. 2, 2012==

'''Chuck'''

I've been looking at the grbl code but haven't done much beyond making
it talk to the StepperNug board. Repo at
https://github.com/chuck-h/grbl.

I have a 4-drive StepperNug kit and 4 stepping motors but I haven't
yet assembled a "mule" for functional testing. I am not expecting to
build a full-scale torch table at my location.

I am planning to adapt the code to work with double home switches on
the x axis so that the two motors can be sync'd repeatably at startup.

Open questions for me
*what control outputs are required for the torch?
*gas torch
plasma cutter
*what do we need to do with z axis?
*preprogrammed (G-code) moves?
*arc voltage height control for plasma cutter?
*What do we want to do for start-of-cut
*build a custom G-code into the grbl interpreter?
*push it back to CAM prep?
*What sort of interactive manual controls are needed
*grbl is primarily a non-interactive G-code interpreter
*x,y,z jog functions
*home all function
*pick up zero reference from part

YK> The mechanical side of the torch table is near completion.
A snapshot of current status would be very helpful!

Cheers,
Chuck

----

'''Darren'''

Hey Chuck,

I like your idea of using a port expander off of the I2C to sense and interrupt for limit switches. If you want to design around that for your dual X-Axis I think it would be great. Adds a lot more flexibility... As long as someone is willing to code it :) (Looking at you Chuck)

I was going to send some of those port expander signals to the expansion ports as well and I think adding the voltage sense for z-height adjustment as a module for that port is a good idea. I don't think everyone will want that voltage sense (Circuit Mill doesn't need that for example.)

Do you think we are going to be able to fit all of this into the Atmel part?

Cheers,

Darren

==November 5, 2012==
I(LoadTest) traveled to SEMA/AAPEX show to get some more ideas. Looking into the possibility of adopting components from tie-rod hydraulic cylinders as standardized by the NFPA(National Fluid Power Association). These same components(tube, caps, mounts, rods, pistons, etc) could be used to not just build the universal rotor but also, OSE hydraulic&electric pumps/motors, hydraulic hose crimpers and much more. Also discovered universal rotor work at: [[Modular_Vehicles]] that is useful.
Per conversation w/marcin:
-Looking for axial load capacity of standard ball bearing flange blocks(tapered roller bearing flange blocks are too expensive)

-Trying to determine if exsisting [[15,000_Inch_Pound_Motor]] are sufficient to survive for direct wheel connection on lifetrack(no extra support bearings/shaft)

-Marcin wants to upgrade to 3" shaft, I'm encouraging him to consider using readily available higher grade steel shafting instead as this is industry proven and less suseptible to fatique then plain mild steel. But I will continue to research the availability of this material around the world and GVCS wisdom for both options.

==November 3, 2012==

Hi guys,
Sorry i've been out of the loop, my harddrive got zapped at the airport. I had the opportunity to(scramble) go to SEMA & AAPEX last minute to get some ideas and hopefully generate some resources for an open source truck. Its the world premier automotive parts tradeshow, about 5million square feet. SEMA is like “Las Vegas”, over-indulgent and disgusting, but its was also a reminder that theres a lot of creative people out there with lots of time and ambition and also loads of money to fund ridiculousness- its just a matter of engaging them in something more practical(OSE) . However, AAPEX was a chance to get my hands on a lot of basic parts(like bearings), mostly from Asian manufacturers trying to capitalize off of the indulgence of the American automotive industry. I guess AAPEX was more like the enormous “working class” in vegas, mostly immigrants and minorities, that are trapped in dead-end service jobs, living in old motels that have been converted into apartments around the newer fancy ones. What a broken system and a testament for OSE!

One revelation from my trip: The NFPA(national fluid power association) has set standards to make tie rod hydraulic and air cylinders interchangeable between manufacturers. Looking at the components of a tie-rod cylinder, I think we can leverage these as GVCS “Legos”. With the same components as you'd use in a hydraulic cylinder, you can also use to make much of:
-Hydraulic/fluid/air Motors & Pumps (vane type: http://www.pumpschool.com/principles/vane_ani.asp)
-Electric motor
-Hose Crimper
-Universal Rotor
-Lots of parts for the rest the GVCS

In other words can the tube, shaft and endcaps off a large hydraulic cylinder(ceb-press size) also be used for a motor's tube, shaft, endcaps, etc. It could save a ton of machining and make the GVCS more accessible/attainable to anyone. The air cylinders are aluminum, so that provides more flexibility. I'm going to check and see if the tubing sourced from hydraulic cylinder suppliers like (baileynet.com) has adequate tolerances to accept bearings(for motors/rotors) without further machining. Then these could be bolt together quick GVCS advancements
We'll have to figure out what dimensions/parts NFPA regulates and a good source for the full line of NFPA components cheap without buying the whole cylinders.
Here is Eaton's NFPA product line:
http://www.eaton.com/ecm/idcplg?IdcService=GET_FILE&allowInterrupt=1&RevisionSelectionMethod=LatestReleased&Rendition=Primary&dDocName=DEV_216614 (4.9mb)
I'm staying for FABTECH which is the 12-14th. If anyone there has a chance to come out it will be a good chance to see a ton of fabrication equipment. You can stay in my room. http://www.fabtechexpo.com
From Joe Justice when I asked about building one of their cars to use at FeF/GVCS:
Josh- that would be epicaly awesome! We are all for our cars out there and being used, ESPECIALLY by groups that are doing awesome like OSE! I'd like to help, maybe we can provide the tires/wheels or something at the very least?
Please plug WIKISPEED :D And I hope you have an awesome time at SEMA! The last time I was there was 2010- and in many ways it blew my mind!

MARCIN:
Can you find out the rated axial load rating for one of these bearings?
The bearings are made by Fitbearings.com as a knockoff of american brands-they were here at the show. They said its not rated for any axial loading and they couldn't provide any data for such. I'll keep looking for data from other MFG's.
Do you want me to look further into mounting the lifetrac tires directly to the hubs on the wheel motors that you have or are you opposed to that? I'm not sure which motors you have. You don't have the ones pictured on the wiki:http://opensourceecology.org/wiki/15,000_Inch_Pound_Motor ($279) These 712s have larger necks. From your videos it looks like you got the 701s with the smaller necks: ($400) http://www.surpluscenter.com/item.asp?item=9-9339&catname= Or did you buy the $300 ones and they shipped you the $400 ones, which commonly happens at surpluscenter.

==October 26, 2012==

I'm looking at 100's of designs. Theres not many universal products, and even the mfg's are pretty application specific and don't have a varied product line, but this is the general direction it is going:

Look at this product range on the 3rd page: http://www.omnigear.com/EBHQR.pdf
The first two for spinning big mower blades, The WN-06 and SN-06 are wheel drives. They also make similar auger drives. Look at MDH-45 in the middle.

-This company only sells to the big tractor mfgs in large quantities so its a slow dance to get them to give me any engineering data.

But look at this one:
http://www.zero-max.com/documents/Zero-Max_OHLA.pdf (5.6mb)
For example: The 1st pic i've attached is the big one at the bottom has a 3.5" shaft but its only about 7" deep + the shaft.

The design will be easy to build with any kind of bearings and little machining and more "quick attach" mounting options.

RE:(With a 3" shaft Modular Wheel Unit, I can see converting the Wheel Unit to a lathe as one of the functions of the Universal Rotor concept)
3" is getting up there. You might also want to talk to your steel supplier about what stronger shaft options are available other then just plain steel. They should have something. If not http://www.metalbythefoot.com/ in Kansas City has 1144 and 4140. And Speedymetals.com and onlinemetals.com have 8620. I'm not an expert, but the material is much stronger, and later on you can make it even stronger/harder with the GVCS induction furnace(or even the wood stove)
Some of those big 20,000lb farm tractors are bouncing around on only 3" shafts. They have 200hp, 5 or 6 foot dual wheels(shaft breaking leverage) and pick up 10,000lbs on the front and back. But they aren't using mild steel.

The way the bearings are supported on the LifeTrac Wheel connect you have the shaft supporting not just the torsional loads(motor power) but also the radial and axial forces from the weight of the vehicle and ramming into things with the loader - it gets really nasty. Thats why all trucks 1-ton+ and lots of machines use a "Full-Floating" design where there is a separate wheel hub to carry the radial and axial and then they get buy with tiny shafts that "float". (see attached pic 2&3) I'm still researching, but i don't think we will do a full float design for the Universal Rotor because it takes more machining, complexity and space. But we can lessen the severity of the semi-float design consequences you're dealing with now.

RE:( Eventually, we will integrate the electric motors, but we'd like to opensource them first. Any leads to electric motor designers?)
Thats pretty hardcore. It might slow GVCS progress down- but hell, more power to ya! The only motor designers i know are working on electric car motors and are very expensive. I'll ask around, if you've narrowed down what type of motors are best for GVCS let me know, otherwise i'll stir up the wiki.

==October 16, 2012==
LoadTest Posted a 2 part video response to the problem statement video filmed at FeF "Quick Attach Plate and Universal Rotor". The first part is an overview of the design considerations. The 2nd part poses the first design decision and that is to eliminate the auxiliary shaft bearing support structure from the design and rely instead on the hydraulic motor's internal bearings to support the system, with the option of adding in an extra bearing support system only when a hydraulic motor with inadequate bearings is to be used. LoadTest requests Aaron and Marcin to watch the response videos and confer with the decision before he continues further design work.
Part 1: [http://youtu.be/LOjaMpe5IXM]
Part 2: [http://youtu.be/5dbpZ0fvdmQ]

==October 9, 2012==
''I'm out all day this week until Friday. I'll try to throw a video together with some ideas. I think the first step is to get Marcin to confirm his decision & the reason for it, which i wrote about on the Wiki, about using the extra shaft and bearings even though they aren't needed. I want to be sure he understands that the bearings in the wheel motors like you are using in the lifetrac now are stronger then the old motors he was using which weren't wheel motors. The old motors couldn't support the weight of LifeTrac, the new ones can depending on which model they are. If it was up to me, i would say don't use the extra shaft and bearings for LOTs of reasons. Especially considering building a Hydraulic Motor from scratch is to be part of the GVCS 50 so it can be made to whatever specifications needed.

Here is the decision as i posted on the wiki:
http://opensourceecology.org/wiki/Universal_Rotor

1) Wheel Motors(bearings built in) or Jack Shaft(with auxiliary bearing support structure)?

Due to the wide range of applications, the UR needs to handle high axial and radial forces. Wheel motors have larger bearings then standard hydraulic motors to resist these much higher forces. Wheel motors are available commercially that will handle the radial and axial loads of all current GVCS applications. However wheel motors are low speed. High speed motors don't usually have such large bearings. While generally you don't need large bearings while doing high speed operations, an accident, such as hitting a tree stump with a high speed mower blade may damage a motor with smaller bearings. Adding a separate shaft(jack shaft) that is supported by separate bearings between the motor shaft and tool effectively isolates the motor shaft and bearings from any radial forces, as well as axial forces if properly designed. This is the design currently being used on LifeTrac III and the MultiAuger. The current design on the LifeTrac is excessive in length and has some proven and suspected issues. A much shorter and simpler jack shaft setup should be possible that is more comparable to a wheel motor in size. If a jack shaft setup is chosen as the primary UR setup, it should be designed so that only wheel motor can be used instead with minimal variation(or none) for replicators who choose to do so.

The current quick connect wheel assembly with the jack shaft and auxilary bearings was a necessary component when the LifeTrac was powered by the original weaker drive motors. However during the redesign, new [[15,000 Inch Pound Motor]]s were purchased which are actually wheel motors that have a much higher carrying capicity which means the whole jack shaft assembly might not even be necessary as the motor is designed to handle up to 11,000 of radial load per the specs provided by the manufacturer. It has already been proposed by Marcin that the wheel connect be redesigned to address several issues, but in reality, it can actually be completely ommited without having to purchase additional motors.

Comparison:
Wheel Motor UR Advantages:
-Much more compact, lightweight, cheaper and very quick to build
-Sealed & lubricated bearings
-Industry Proven
-Less parts to break or wear out

Auxiliary Bearing UR Advantages:
-Can remove the motor with out disconnecting the tool(or the tire when used as wheel drive)
-More motor choices (especially rpm)
-Can use a gear reduction or multiple motors much easier

Thanks,

JB

=Daily Log=

==Saturday, Dec. 1==

[[Accounting System Log]] updating. Marcin asked about the current status of the backhoe work - Josh is running with it now - I'm focusing on strat plan and accounting - check with him and lenny-wayne on all updates on its status. Met with RandyP - he chimed in on the payroll requirements - see his comment under payroll in the accounting system log - he is mocking up a manufacturing accounting chart of accounts in gnucash and also outlining our chart of accounts in the linked document - he will have that to me before wednesday.

==Thursday, Nov. 29 & Friday, Nov. 30==

Downloaded 10 strategic plans/annual reports from leading non-profits to compare our design work to it. Synthesizing shuttleworth app and strategic plan - narrowing goals into 5 categories as industry standard. All shuttleworth goals are still reflected in the larger categories. Will upload document on Sunday.

==Wednesday, Nov. 28==

*Continuing the push to get the strategic plan publication ready for final review this week.
*Met with Josh Bond to discuss the backhoe smart mob and the development of the smart mob platform in general. We traded ideas and resources and he's running with the development of the platform and the development of the backhoe with Lenny-Wayne and Ward Holloway.
*Met with Luis Diaz and agreed to partner on the writing of the [http://opensourceecology.org/wiki/Hybrid_Structuring_Strategy OSE For-Profit Development Plan].

==Tuesday, Nov. 27==

*Strategic plan graphic design - focusing on trying to get this entire document ready for final review this week.

==Monday, Nov. 26==

*[[Media:OSE_-_GVCS_Packages.pdf|Global Village Construction Set Packages Graphic]]
*Asked Elifarley to change link from OSE main page 'About' section to wiki [[About]].
*Finishing logic model page & incorporating shuttleworth pitch language into strat plan.
*Accounting system work - learning gnucash software.

==Weekly Goals==
'''Please follow [[Work_Log_Guidelines#Requirements]] for content and formatting. This makes review quick and effective'''.
*Have review draft of strategic plan ready for advisor review. '''What does this mean? You mean publish a well-formatted version of strategic plan?'''
*Have all financial information put into the new accounting system and financial statements generated. '''Please clarify the state of accounting system. I talked to Dan extensively on the need for accounting sysetm PRIOR to making any new hires - thus, hiring is on hold until this is shipped. Need clear deadline on this.'''
*Meet with Josh and Lenny Wayne about next steps - updating our collaboration process. '''What is the outcome? A work plan? The production run is not happening, so what is the next steps? I propose Production Run prepared for, after all of Josh's details are accounted for - for Fro-Sat Feb. 1-2.'''
*Luis Diaz - touch base and see what collaboration potential there is.
*Populate [[About]] page.
*Research free computer options for remote collaborators.

==Sunday, Nov. 25==

'''Backhoe'''
*Design review meeting with Marcin and Lenny-Wayne.

==Saturday, Nov. 24==

'''Strategic Plan Graphic Design'''
*Received update from Marcus - he is working on the graphic design for the cover.

'''Accounting'''
*Met with RandyP for 3 hours: chart of accounts, general ledger, fund accounting
*He will meet with me again this week
*I need to finalize the chart of accounts definitions before we meet
*Downloaded [http://www.gnucash.org/ GnuCash] - open source accounting software - this is a good option.
*The crux of the accounting system, since financial statements can be generated automatically, is to understand the different types of accounts and how to appropriately label transactions. The software can take care of the rest.
*Financial controls can be simplified.
*We can start using accounting for production runs and gather economic metrics comparing the stats of the production run in a way that's compatible with financial accounting systems. This would make our data compatible with business plans/enterprise models, and seamlessly integrate with the tax system. For example, we could know the true costs of a production run, from labor hours, material costs, even depreciation of equipment, and extrapolate that for x number of sales per year to project revenue & the profitability of an enterprise.
*I'd like to recruit another accountant to review this process after RandyP and I get it working.

'''Hay Cutter'''
*Ward Holloway participated in the backhoe smart mob. He downloaded the CAD file and made changes of his own that he submitted.
*I asked him to tell me about his skill level and invited him to do a first draft of the [[hay cutter]].

'''Personal'''
*I need to get internet set up at home. I have to work out of coffee shops right now. There are lots of types of documentation that I'm not uploading right now, because I don't have the time.

'''Backhoe Smartmob'''
*Lenny-Wayne sent this spreadsheet for calculating the strength of hydraulic cylinders.

'''OSE Main Page - About'''
*Asked Elifarley to alter the link from the 'About' button on the OSE main page to:
http://opensourceecology.org/wiki/About

'''Backhoe Smart Mob'''

*Posted invitation to smart mob on the following forums:
:*[http://www.mechanicaldesignforum.com/showthread.php?2534-Backhoe-Design-Open-Source-Please-Review-the-Design&p=8968#post8968 Mechanical Design Forum].
:*[http://www.reddit.com/r/MechanicalEngineering/comments/13oz99/open_source_backhoe_design_please_review/ r/MechanicalEngineering]

[[File:Smart-Mob---Backhoe.jpg|right|200px]]
'''Backhoe Smart Mob'''
*48 people were in the smart mob platform at one point - I think over 60 or more were there in total. Not many people engaged - need in-house review to figure out how to get people to comment.

'''Accounting System'''
*Basic accounting workflow: General Journal to General Ledger to Financial Statements
*Confirmation of industry standards - policy is being written [https://docs.google.com/document/d/1AAw75CawTxvAsIaZQgNKUg5n-oXJwds-EtbO3ueiL84/edit here] (research notes are at the end of the document).
:*Source: [http://www.youtube.com/playlist?list=PL57CF2E8398A312E7 Larry Walther]
*Met with RandyP for over an hour. The meeting was comprehensive and educational.
:*Since we have discretionary funds, we need to incorporate Fund Accounting - grants have limited and specific uses.
:*We will need manufacturing accounting systems for the production of GVCS machines for sale. Each production needs to have its own account, inventory, etc.
:*He confirmed the basic accounting workflow.
:*He volunteered to help us take our accounting system to an elite level. He volunteered to come to Factor e Farm and work on site for an 8 hour period - he has accounting software that he can donate and get us to an institutional level of financial accountability.
:*He suggested that we get a laptop that is only used for accounting as part of our financial controls.
:*Open question - he says spreadsheets are a possible use path, but once we scale he thinks we'll outgrow them. The debate arises, because proprietary software is not scalable. Is there an open source accounting package?
:*He said he can build financial statements from the work we've done, and then build the system for the future moving forward.
:*More notes are linked above.
:*Next step - work out a time for him to visit FeF and set this up. He has over 25 years of experience doing this - it is a major help to have his involvement.

'''Lenny-Wayne'''
*Updated us saying he wants to use a single 4" cylinder on the boom instead of two 2" ones like the current design has. He said he will redraw that up in time for our meeting with Marcin on Friday morning. We should have a BOM from him as well in time to publish the blog post and to initiate the Backhoe Smart Mob in time for the publication of the Friday OSEmail.

'''Ewing Marion Kauffman Foundation'''
*We spoke today about them inviting us to come show our documentation to their board in mid-to-late Q1 2013.
*We have a new grant deadline of June 31, 2012 with a final grant report due June 15, 2013.

'''Strategic Plan Graphic Design'''
*[[Media:Opensource_ecology_small.pdf|First draft of project]]
*Tyson submitted the first draft of his project.
*I asked him to improve the background and submit the source files so we can modify them if we want.

'''Dan McCormick'''
*He and I met for an hour today and discussed our general fundraising strategy.
*He and I also talked about working with him on a contractual basis. I asked him to tell us what specific deliverables he would give us, and he agreed to map those out for us in detail in a week or week and a half.
*He said the important thing, now that we've got our organizational development happening, is to generate the sizzle that draws people to the steak. This is the storytelling. This seems obvious, but it really confirms what many other advisers have told us over the past few months.
*He says that everyone who gets grants comes back and thanks the foundation for the money, but the important thing to do is come back and show them exactly what you achieved with their grant - what good did it do in the world.
*He confirmed that it is still a possibility to get a grant from Nicholas Sparks.
*'''General Offer''':
:*Funding Strategy
:*Structural about Management and Organization
:*Practical working between non-profit and for-profit
:*Understands lifecycles of organizations
:*good idea guy about how to get in play our ideas

*He promised to deliver the BOM by Thursday as long as his pain doesn't get so bad he can't work.

==Nov. 13, 2012==

'''Backhoe Blog Post'''

*One of their students got a new job that pays more than he's ever gotten (he's 53) partially because of his work for OSE on the PowerCube VI drawings that he listed on his resume.
*We are planning on doing a blog post once the tractor drawings and model are submitted.

'''Echoing Green'''
*Looked into the application rules since the deadline is coming up - we don't qualify anymore because we are more than 2 years old and we have already received a significant amount of seed funding. Plus Marcin is only 3/4 black.

My goal this week is to publish the strategic plan.

Metric CEB Press

2012-12-02T02:15:41Z

Donovan:

{{OrigLang}}

==Introduction==

There is an effort to redesign the CEB press to Metric specifications underway as of June 1, 2012.

[[File:Metric-Frame-Stage-10.jpg|200px|thumb|right|Metric CEB Under Sketchup Construction]]

The most crucial changes have been made to the drawer and the frame. The metric frame is based on 16cm U-Channel (C-Channel) steel instead of 6" steel. The drawer is now 18cm high. Quantities were rounded up so as not to dilute the strength of the design. Some modifications were made to the relative thicknesses of the drawer components. The net strength should be about the same. M24 bolts have been selected as the main frame fasteners. These come in metric "10.9" stength specification which appears to be about the same as the grade 8 bolts used in the original design.

The hopper has retained its original length and width dimensions; the thickness of the steel has been changed to 3mm from 1/8" (3.17"). This is a notable exception to the rounding up design procedure mentioned above.

So far, a preliminary reworking of the drawer, frame, arms, legs, feet, grate and hopper has been done in Google Sketchup. A spreadsheet file of metric part sizes is also to be made available soon. More work needs to be done on sketchup models of the sensors, holders, shaker mount and a few other details. The new CEB modifications made by James Slade are also to be incorporated. A Chinese version of the Bill of Materials has been created.

Please contact William Neal (william(dot)j(dot)a(dot)neal(at)gmail(dot)com) and Adam Messer messerad ==at) gmail (dot__ com with any comments or questions or also check out [http://groups.google.com/forum/?fromgroups#!forum/cebmachines CEB Machines Mailing List]

Here are some associated files (more to follow). These may serve as a basis for creating a metric version of the build instructions. The original files were prepared with extensive use of Chinese characters so that the Chinese engineers could use them. An English-only version of the files is under preparation.

==Bill of Materials - China==

Most of the required parts have been sourced in Nanjing, China. A few were obtained from "TaoBao", the Chinese "Ebay" site.

Donovan: /* Current objectives */

==Introduction==
My name is Donovan Jones. I am a software developer from New Zealand. I am a competent wiki editor and plan to assist the OSE in this capacity. I do not plan to collaborate or assist in other ways in the medium term. Essentially I am a [http://en.wikipedia.org/wiki/Wikipedia:WikiGnome WikiGnome], as such it is probably safe to ignore me.

If you don't like some of my edits please let me know on my talk page, I don't want to step on any toes, but I'm not going to seek approval for every edit. On aggregate I hope you will agree I am improving the wiki, so let me know when you feel I am not.

==Current objectives==
* '''MJ request''' - [[How_to_Create_Frames_and_Windows_in_Media_Wiki]] for [[Flashy XM]], [[Flash Mob]], and other pages.
** investigate support for widgets on ose wiki, if available try: http://www.mediawikiwidgets.org/Iframe
** I do not have permission to edit pages in the Widget namespace. So cannot try out this widget on the OSE wiki.
* Fix broken links to [http://opensourceecology.org/w/index.php?title=Special%3ASearch&search=openfarmtech.org&fulltext=Search openfarmtech.org].
* [[Wiki_instructions#Style_Guidelines|Improve metric support]] on the wiki.
* Work on [[Work_Log_Guidelines]] particularly the [[Date_Format_Convention]].
* Work on and improve [[Special:Categories|categories]].
* Wikifying pages: work on wiki linking.
* General grammar and spelling fixes.

==Future objectives==
* Collaborate with my father to contribute on Biofuels particularly [[butanol]].
* Creating custom wiki templates
* Creating custom OSE infoboxes
** keep any eye on http://meta.wikimedia.org/wiki/Wikidata which will make creating infoboxes much easier.
** software infobox to include:
*** licence
*** ubuntu package name

==Thoughts==
As an outsider there are a few observations I would make about things that could be improved.

===Support for the Metric System===
Three countries use non-metric measurement systems: Liberia, Myanmar, and the United States. I believe for OSE to a have a global impact it needs better support for the metric system. Many collaborators will only be able to source metric parts. I want to help provide better metric support at least on the wiki.
====Using Conversion Templates====
Complex conversion templates are available from other media wiki sites eg: http://en.wikiversity.org/wiki/Template:Convert. This system is very comprehensive http://en.wikiversity.org/wiki/Template:Convert/list_of_units but is quite complex and requires subtemplates. I have done a proof of concept with temperature conversion:

* <nowiki>{{convert|60|°F|°C|sigfig=3}}</nowiki> = {{convert|60|°F|°C|sigfig=3}}
* <nowiki>{{convert|16|°C|°F|sigfig=3}}</nowiki> = {{convert|16|°C|°F|sigfig=3}}

If OSE wish to use these templates I suggest following the instructions at http://www.mediawiki.org/wiki/Help:Templates#Copying_from_one_wiki_to_another, this will be much easier for someone with import rights on the OSE wiki (I do not have these rights). Without import rights each subtemplate needs to be copied manually which is tedious and is prone to cut and paste errors.

===Wiki standards===
Standards like the [[Date_Format_Convention]] are important in a wiki, they create consistency, help define a framework within which people can become more productive and in general help to make the wiki more functional. As such I will be editing peoples Logs, please let me know if you would prefer I left them alone.

===Date formats===
I have a definite opinion about what the best date format is but I will not be converting dates to this format or pushing this other than recommending it here.

The best date format is the [http://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format. It looks like this: '''2012-11-27''', compare this to '''02/04/03''' which has three possible interpretations.

The reasons it is best are:

* it is unambiguous.
* it sorts correctly using string or numeric sorting.
* it is a formal standard.
* it is widely used.
* the format can also be used to represent precise date and time, with timezone information.

see also: http://www.w3.org/QA/Tips/iso-date

==Other Skills==
I do have some other skills that may be useful to the OSE. I am an experienced data munger, if you need scripts written to process and convert data feel free to drop me a line. Things like

* Writing cron jobs
* Talking to databases (postgres/mysql/sqlite)
* Pulling in xml,yaml,json,html,csv,wiki markup
* Spitting out xml,yaml,json,html,csv,wiki markup
* Talking to REST web services.
* Screen scraping and web automation.

My language of choice is perl. My collaboration method of choice is [https://github.com/donovan github]. My development environment of choice is ubuntu. My server environment of choice is ubuntu/debian.

==CAD_CAM_EDM_DRO Yahoo Group==

*'''This groups provided the most useful advice: it addressed the questions asked specifically.'''
===Answer 1===
Belt works well on plasma cutters. Screws are usually too fine as you
need speed more than resolution.

The holding torque figure for a stepper isn't actually very helpful. As
soon as you start moving the motor, the torque falls off. As a rough
rule of thumb you can only use about 1/4 of the motor's holding torque.
Your 425 oz-in motors will effectively produce only about 100 oz-in.
With a 2" diameter pulley you will have a maximum force of 100oz
(torque/radius). As you have two motors you will have a linear thrust of
about 200 oz or 12 lbs. At a guess you will probably lose getting on for
half of that in friction, giving you about 6 lbs useful force. For
accurate cutting you need good acceleration. I would think 0.5g would be
a minimum to aim for. Therefore your gantry can't weigh more than 12 lbs
total. That is pretty light. The good news is that you will have a very
high top speed, assuming you have enough acceleration to get there.

If you use a 1" diameter pulley the numbers look a lot better. The
thrust per motor now becomes 100/0.5 = 200oz. As you are using two, that
becomes 400 oz total, or 25 lbs. You still lose about 6 lbs in friction,
leaving 18lbs to accelerate your gantry. The gantry can now weigh 36
lbs. Assuming a maximum reliable speed of 1500rpm from the motor you
will have a top speed of 750IPM. That is pretty damn quick.

I wouldn't recommend using the belting flat . You will probably find
that the pulley engagement is not smooth and you will get slightly rough
motion. A far better method is to use two idlers to wrap the belt around
the pulley. Think of the Greek letter omega. I'll try for some ascii
art but it may not come out very well:
O
| |
__O O___

The idlers can be made out of a cheap skate bearings. Skate bearings are
8mm wide so two side by side will be wider than the belt. 3/8" pitch
seems quite coarse to me. On the next page in the McMaster Carr
catalogue they have some 1/2" wide XL belting. That would also allow you
to use a smaller pulley.

Les
===Answer 2===
Marcin:

If I were to make a 4 x 8' oxyfuel machine which needs to run at 30
IPM (MAX !!), I'd make a single side drive for the 8' axis and use a
delta shaped frame requiring the main rail be maybe 3' longer on the
driven side. Thus you will need TWO steppers for your drives, and
you can use (2) Gecko Systems 10x microstepping amps.

Use rack and pinion drive for both axes. Rack can be gotten from
Standard Steel Specialties, [http://www.stdsteel.com/gear.htm stdsteel.com/gear.htm] at a cost of around $23 for each piece if 1/2 x 1/2 x 6 feet length in quantities
of (2) pcs. They stock 20 DP, 20 degree pressure angle rack. I would
ask if they could supply 24 DP, 20 degree rack as we used to buy
these from then in quantity.

Since the drive pinions need to have at least 18 teeth in order to
have no undercutting, these are the smallest pinions you should use
if you wanted direct drive. If you were to use 24DP, 18 tooth
pinions with 10X microstepping, you would have a resolution
of .0011781 inches per microstep.

As to the available force from this setup, I must respectfully
disagree with Les Newell regarding the torque/force available at low
speeds. Looking at the Pacific Scientific spec sheet for NEMA 34
frame single stack N31 motors with microstepping (.707 x torque)
gives about 315 ounce inches at this very slow speed. With an 18
tooth pinion, radius = .375 resulting in 840 Oz force or 52# force.

While I might practically opt for some sort of belt reduction
between the stepper and the pinion so as to use a larger diameter
drive pinion, the numbers above are still quite realistic.

To summarize,
1) Use rack and pinion drives
2) Drive the relatively narrow side (4 ft. wide machine) from one
side; design the main carriage and main rail to do this.
3) You can use direct drive with a resolution per step of .0012 per
step

I have pictures and data from my small test bed machine. You can

Marcin,

If gear rack comes in 6 foot sections, here is a joining procedure:

[[Image:gear_rack.jpg]]

Use metal rack and pinion for durability, as opposed to rubber (neoprene) belts.

>>You can get pinions from [http://bostongear.com/company/contact.html Boston Gear] and [http://www.martinsprocket.com/ Martin Sprocket and Gear]

I am curious why you would want to do a one-motor drive for the long axis. Is that not more difficult to keep aligned than a symmetric drive?

>>I started C & G Associates (now a part of Thermadyne) and designed several cutting machines over the years as well as tracing and drive retrofits. Most early cutting machines were cantilever, single side drive setups. Single side drives are simpler to build. However as you will see from the pictures, they have a "delta" style frame wherein the main rail is longer than the slave side rail. One uses two sets of "side guide" bearings to control the squareness of the main carriage. The first set is in the front roughly in line with the cutting torches; the second set is behind the first pair by maybe 3 feet in the case of a 4 foot wide machine.

You must be sure that the main rail is straight throughout its length. So now as the carriage rolls from front to back, the two sets of side guide bearings maintains squareness thru the entire travel. One can assure straightness by using a piano wire spaced off the main rail by maybe 1/8 inch, front and back. We used a small optical magnifier which had a graticule engraved in the optics, so we could see a .005" variation in straightness. I took some pictures for an eralier inquirer and could send them to you if you want.

For oxyfuel operation this style machine will work very well. We sold single side drives for plasma operation as well. For larger, heavier machines, and faster (plasma) operation, dual side drives are superior.

One of the small machine we made, the one shown as "PlasOpBack", we actually had (2) gear racks setting teeth-up on the top of the table; a single motor-gearbox drove both sides through use of a long cross-shaft with pinions on each end contacting left and right side racks.

Please consider the new conceptual drawings:

Thanks,
Marcin

Marcin: Hello,

I am looking at Xylotex.com 425 in oz motors to drive the long axis of
a 4'x8' torch table. I'd like to use a 3/8" pitch by 1/2" wide belt
that functions as a rack. The pinion is a pulley of 2" diameter. I'd
like to have one drive motor on each side of the long axis.

Would I be able to drive the pulley directly with the motor, or do I
need some gearing on the motors?

I've considered ball screw assemblies, but it appears that I don't
need such high accuracy, and simple belt drive will get me at least
1/30 inch accuracy on the torch table, if I don't use microstepping.
Are the 3/8" pitch pulleys sufficiently accurate for this? I am trying
to do the rack-and-pinion belt instead of ball screws for lower cost:

Marcin

===Response 1===
Marcin,

I looked at the website/blog pretty interesting stuff, you are doing
your homework.

To do to it right, you need to do some motion analysis on your drive
setup. The gear ratio you will require depends on the weight (mass) of
your carriage. If you look at the big commercial makers, you will see
that they have a reduction between their linear drives (mostly gear
rack) and the motor output. The reduction needed depends on the
reflected load inertia to the motor, the inertia of the motor itself and
the power (torque curve) of the motor. There is some free to use motion
control analysis software out there that you can download and do this
analysis with.

Another hint - if your drive system is rigid, you have to use
microstepping. Otherwise you may miss steps. If your drive system is
sloppy and the gantry inertia is very low you may be able to get by
without microstepping. Otherwise it is required.

I'd probably look at 1/4" pitch belt for better accuracy. 3/8 is a
little coarse but it might work fine also. If I were to do a one off
table for myself I'd take a good look at roller chain for the long
drives. I think it might be cheaper than belting overall and perhaps
more rigid.

Good Luck,

Dave

===Response 2===
Marcin, I have a few comments.

I very much recommend against the round rails.
Use linear guides, second hand if you cant afford the new ones.
The round rails will bend appreciably with the forces you get when using
a router on wood or an end mill on metal.
I know most hobbyists use them - but that does not mean its a good idea.

Mxl timing belts may not be strong enough.
Accuracy is not you problem, strength is.
Mxl is not able to transmit the power you need at the speeds you need.
Timing belts strength are dependant of speed - when cutting, your
effective rpm may be well under 10 rpm.
At that speed mxl and xl are simply not strong enough.

Use '''HTD pulleys and belts, 15 mm width, 5 or 8 mm pitch'''.
They are stronger, transmit more torque and would be a much better choice.
They are very accurate, more than you require.
Note that the belts are put on quite tightly for 8 mm htd. If they are
slack, they wont work nearly as well or accurately.

Use microstepping. Its really, really important.
Don´t even consider non-microstepping solutions.

The motors are good for this application.
Proper tensioning of the belts means that you overload the axels on the
Nema 23 motors -
they don´t fail immediately,but they may have a very short life.

Its more work, but a bearing and coupler will make it a much better
solution.

The design is classical, well proven, and should work very well.
===Response 3===

A friend of mine has a CNC plasma table and the X
axis (gantry type) uses 2 nema motors with gears and a
toothed track. No gearing or long belts. Works "real"
good.

2" might be a pretty good load, acceleration profiles would need to be
tweaked. What does the proposed carriage weigh?

Direct, unless that would exceed your target rapids speed. The 425's are a
bit slower than the 262's. The accel profiles will be slow, probably at
least a second to full speed if that is as heavy as the drawing implies.
Full speed will be tooling right along mind you. Much faster than the torch
can cut. :)

I would definitely use microstepping just for the smoothness in motion it
imparts. Faster accelerations can be achieved when you aren't asking the
motor to do a full step if its motion is constrained by a high inertia load
such as the carriage of a 4x8.

>Are the 3/8" pitch pulleys sufficiently accurate for this? I am trying
>to do the rack-and-pinion belt instead of ball screws for lower cost:

I would think so, but tension might be critical for backlash control, and I'd
think a plastic track to support the bottom, return run would be helpful as
it would reduce whipping. As would of course some method to keep the debris
out of the works.

I wasn't aware that those belts were available in those lengths as you would
need around 17 to 18 feet in linear measure, twice.

>http://openfarmtech.org/index.php?title=Torch_Table

I think I would replace those heavy guide rods on the carriage with even
larger and more rigid thin walled pipe as it would reduce the traveling
weight. Fawncy linear bearings can be replaced with triplets of sealed skate
wheel bearings for both cost reduction and some weight reduction. For the
bed rails too for that matter. To help keep dual motors in step, I'd want to
face the rears toward each other and couple them together with a long hollow
drive shaft but that's just me. Two separate homing switches would probably
work just as well though. If the motors get out of step in actual operation,
you have a tuning problem in the software anyway.

A neat idea, I wish I had room for something like that.

==Arnar Mar Sig, Iceland Fab Team==

===Power, Speed, Accuracy===
I was thinking about using steel for the main support frame welded together at the joints, but it would be easy to change that part to bolt together type. The Y and Z axes would be made from aluminium bolted together. The reason for the steel frame is to get maximum support and stability if the axes are moving fast.

You can post it and get input as you want, Its open source;)

The reason for linear bearings and screws on the X axes is so i dont have to move a big and vibrating motor with the axe. This is propably the biggest motor on the table. Also using the design that torchmate uses then we need 2 motors on both sides.

The most expensive part of the controller board are the power transistors. If one didin't need the 30-50V 6A output then we can change to smaller transistors. Also i have dedicated stepper motor IC's to control the critical timing so its a bit more expensive then using a generial purpuse microcontroller like most designs use, but thous designs can't step really fast. Also many other "open" router table designs still relay on proprietary controllers.

I will most likley use Olimex (http://www.olimex.com) to fab the PCB it costs 30euro to fab 1x 100x160mm board. I can do single sides boards at my shop but this board has to be double sides.

The controller board has a small 8-Bit AVR to communicat with the dedicated IC's and a computer. I haven't started the code but its really simple and written in C and small parts in assembly. The controller will communicat thru RS232 or Ethernet (if we add that option, and it would be really nice to have). The controller will be able to take in simple commands like "Move this axe to position X at Y speed", so it will be able to work standalone without Smari's routing software.

I haven't found any open source controller that has the power, speed and accuracy i want, thats why i'm doing this design.

===Basic electronics specs===
When building the router you should be able to use almost any Bipolar stepper motor that has the power to drive the mechanics. I'm designing the motor driver now, the specs are:
Support for 3x Bipolar steppers, 30-50V max 6A (200-250W)
Input for 3x incremental encoder for step verification and currection.
Max step freq of 20kHz
RS232 port for programing (Maybe USB)

The board will probably cost between 300-400$us to make.

If you have any input on the design or the machanics then please tell.

===Capacities===

I just started drawing the CNC rouer in [[Solidworks]] yesterday. The
basic version will have 3 axes with an changeable head. The head can
be a cutting head, plastic extrude, acetylene/plasma cutter. (The head
could also add another axe for 4-5 axe version). I was also thinking
about adding fittings to be able to add a rotating spindle to do CNC
lathe work.

I've started the design of the motor drivers as you know Smari and I
can probable finish the design and send the pcb out to fabrication
this weekend.

Casting aluminium isin't so hard. Making the molds is also simple and
cheep, just expanded polystyren and plaster. Molds can also be created
in sand, but its not as good.
Casting carbon fiber is almost like doing fibreglass, you can do it at
home buts is messy.

===Project Budget and Goals===
Arnar,

I like the one motor design. I think the Torchmate drive system is more complicated, such as the one motor on each side.

Tell me more about the power transistors. What is the particular transistor you're using? Can you redesign to simply use a larger number of smaller transistors, or is that ineffective?

So look at the budget:

1. Structural steel - $400

2. Control board - $400

2a. Encoder - $100 for each axis - if needed

3. Control software - free

4. Stepper motors - $100, main

5. Stepper motors - $100, 2 smaller ones - [http://www.xylotex.com/StepperMotor.htm from Xylotex]

6. Ball screws - 13 feet total plus 3 ball sets - $300?

7. Linear bearnings and shafts: 26 feet - $300?

I just sent for a quote to Nook Industries for the parts in the XYZ-table diagram, http://openfarmtech.org/index.php?title=Torch_Table .

Those last two are my guesses, but that's about $1600 - 1900 total?

What kind of accuracy are you aiming for? The ball lead screws from Nook Industries are down to +-.0004 inch. I would need only .01 for the purposes of CEB. Have you considered simple threaded rod? It's $23 for 10 feet of 1/2" rod, part 98935A632 at http://www.mcmaster.com/ . Or, $40 for precision threaded rod, 6 feet of 1/2". The precision rod is down to .009 inch accuracy per foot of travel. That would do for me.

Then again, if one attached 2 nuts to a simple threaded rod, the backlash (play) would decrease. That may be another route for the cheap way.

What do you do professionally? Are you an electrical engineer?

Are you looking to neo-commercialize (see http://www.p2pfoundation.net/Neocommercialization ) the XYZ table? Are your goals similar to mine, like the open franchising of the CEB press - http://openfarmtech.org/index.php?title=CEB_Press ?

Marcin

===Encoders, electronics component prices===

I took together the parts needed and checked the prices. The full controller with all features will cost about 307$us (ordering components for just a single unit). By removing the Incremental Encoder support (and also decreasing accuracy), the unit can be build for 232$us. After checking the prices i found that the transistors aren't that expensive. You can cut the number of transistors used to 12 and then only having max 3A output, but the price is only 17.76$us lower.

That budget looks about right, the only thing missing are the incremental encoders if one wants to use them, they are about 50-100$us for low end 1024tick/rev, 3 are needed.
I was hoping to build this for between 2-3k (a bit more expensive to build in iceland)

I want to be able to mill PCB boards with this router, so 0.1mm (.003") is the minimum accuracy i want, but having down to 0.0004" would be awesome. For most DIY people a simple threaded rod and bolt would do. I want this do be a "neo-commercialize" project. All the hardware, mechanical and software designs should be open source and everybody should be able to build the machine and use the parts they want (skipping encoders, using threaded rods.. etc) to get the accuracy the want, but I still want to be able to sell complete machines with the best accuracy we can get (hense everything is deisgned for maximum accuracy).

I do Software programing and electrical designs for Valka (www.valka.is). We make fish processing machines.

===Guide Rails, Encoders===

Just talked to Nook Industries. I was told that the linear bearings and shafts are about twice as expensive compared to profile guide rails, so I'll get a quote on that plus ball screws and pass it on. Just a data point.

We can redesign structure easily if needed, by just replacing the linear shafts with linear rails. The rails are supported on their whole length, as opposed to linear shafts, which are supported at the ends.

Their turnkey package for motors, controllers and encoders is under $5k. So looks like your work is Factor 10 Engineering (http://www.10xe.org/). I love it, because $500<$5k. In my language, that's 10 times more freedom.

===Electronics, BOM===

Hi Marcin

I buy most parts from Digikey, the TMC* parts i will probably buy from semiconductorstore.com or some other place if i find them.

I'm going to redesign the router to have at last the X and Y axes on profile guide rails and cut costs a bit.

Yes, its a Open Office spreadsheet. You can open it with OpenOffice on Mac, i find it a bit less of a crap then Microsoft office on mac, but it still sucks.

Your right, its simpler to driver a unipoler motor and most DIY projects choose to use them. Bipoler motor has one winding per phase while a unipoler has 2 winding per phase, but at any given moment there are only 2 windings in use. This makes a unipoler motor with the same torque as a bipoler motor bigger, heavier and more expensive then bipoler. You can also buy steppers that are hybrids and can be driven both ways.

The driver IC's i'm going to use take care of the motor driving so it dosen't matter much in the end except for cheeper and less heavy motors:)

Arnar,

Can you resend partlist.ods? I'm just getting a blank page.

Xylotex has 23 Nema motors at $50, http://www.xylotex.com/StepperMotor.htm, so that's cheap. Are those the type you plan on using? If it's got two phases, that makes the 6 amps you're talking about?

Have you considered power scaleability by attaching 2 (or more) double-shaft motors one behind the other? That would be a good feature for high power, such as lathing, or even adopting a similar design to milling. Is your controller capable of being paralleled, such as using 2 (or more) controllers to drive the additional motors, so we can scale the power completely? That would be a useful feature from the standpoint of scaleability. This would be quite exotic to have, and I always aim for such. For example, the Boundary Layer Turbine is absolutely power scaleable by virtue of adding disks: http://openfarmtech.org/index.php?title=Boundary_Layer_Turbine

So your strategy is to put the complexity into electronics and not into the motors, as electronics are cheaper, right? That's the same strategy as hybrid electric cars: rip out the transmission and replace it with electronic torque control such as PWM.

Hi Marcin.
I would really suggest a Xylotex drive or other known professional drive.
I use the Xylotex for my Taig mill. [http://www.xylotex.com/3DB-116.htm]
They cost about $500 with motors, but you get $500 worth.
I wouldn't trust many drives I see on ebay to run a "real" mill / router table.
There is also the Linistepper kit for unipolar motors. I know these work.
Cost is about $100 for 3 axis
[http://www.piclist.com/techref/io/stepper/linistep/index.htm]
CNC software will run standard G code that is output from CAM to the machine.
G code is machine commands & machine coordinates.
I use Corel draw to make the parts, save as .DXF & convert to g code using Lazy CAM, part of Mach3
Mach3 actually runs the mill table. [http://www.artsoftcontrols.com/artsoft/index/index.htm]

The software (turbo CNC / mach3) reads the g code & feeds it to the Xylotex drive.
I'm in a studio apt now so I can't build anything big.
There's a lot of stuff on ebay & [http://www.cnczone.com] is a really good place to look.

$50 for Torchmate 3 size stepper motors: [http://www.xylotex.com/StepperMotor.htm]

==Jeff at Xylotex==

support@xylotex.com

A 4 X 8 table is quite laqrge, but some people in Canada are driving a
similar sized table with Xylotex drives. See a picture [http://www.xylotex.com/Gallery/Gallery.htm here] (top rightcorner).

I would recommend running with 2 leadscrews on the side rather than one
down the middle. This way your center, cutting area does not have the
leadscrew in the way.

If you use 10 tpi screws with the 269 oz.in. motors you should get
around 75 IPM on a system with smooth running ways. You might be better
off with 5 tpi screws and then use the 425 oz.in. motors, though.

You can use turboCNC OR Mach, but mach will provide "slaving" which
allows two motors to be driven on the same axis. I'd recommend use Mach
if you do decide on the recommended dual leadscrew design.

If you use Linux, then I would recommend EMC2.
----
The 425's with 5tpi will give a faster movement. You need this with
Plasma Torches (when cutting thin metal) to keep from destroying the
work. 269's with 10 tpi will give a decent speed, but with plasma you
need the speed, and the 425's would give better result I think. I
haven't tried the 269's with a 5tpi screw. They might work just as
well, since there really isn't a large load to move with plasma tables
(i.e. no cutting forces to overcome). A 5 tpi screw may have the same
diameter as a 10 tpi screw, so rod thickness wsn't a consideration.

I don't know if EMC2 has the capability to "slave" one axis to another.
This could be done using an external break-out board and wiring the A
signals over to the X. Another option would be to copy all X movements
in a program so they will be X and A movements. This would be an option
for small programs, or if you have a good search-and-replace program.

I do not plan to collaborate or assist in other ways in the medium term. Essentially I am a [http://en.wikipedia.org/wiki/Wikipedia:WikiGnome WikiGnome], as such it is probably safe to ignore me.

If you don't like some of my edits please let me know on my talk page, I don't want to step on any toes, but I'm not going to seek approval for every edit. On aggregate I hope you will agree I am improving the wiki, so let me know when you feel I am not.

** software infobox to include:

==Thoughts==
As an outsider there are a few observations I would make about things that could be improved.

===Support for the Metric System===
Three countries use non-metric measurement systems: Liberia, Myanmar, and the United States. I believe for OSE to a have a global impact it needs better support for the metric system. Many collaborators will only be able to source metric parts. I want to help provide better metric support at least on the wiki.
====Using Conversion Templates====
Complex conversion templates are available from other media wiki sites eg: http://en.wikiversity.org/wiki/Template:Convert. This system is very comprehensive http://en.wikiversity.org/wiki/Template:Convert/list_of_units but is quite complex and requires subtemplates. I have done a proof of concept with temperature conversion:

* <nowiki>{{convert|60|°F|°C|sigfig=3}}</nowiki> = {{convert|60|°F|°C|sigfig=3}}
* <nowiki>{{convert|16|°C|°F|sigfig=3}}</nowiki> = {{convert|16|°C|°F|sigfig=3}}

If OSE wish to use these templates I suggest following the instructions at http://www.mediawiki.org/wiki/Help:Templates#Copying_from_one_wiki_to_another, this will be much easier for someone with import rights on the OSE wiki (I do not have these rights). Without import rights each subtemplate needs to be copied manually which is tedious and is prone to cut and paste errors.

===Wiki standards===
Standards like the [[Date_Format_Convention]] are important in a wiki, they create consistency, help define a framework within which people can become more productive and in general help to make the wiki more functional. As such I will be editing peoples Logs, please let me know if you would prefer I left them alone.

===Date formats===
I have a definite opinion about what the best date format is but I will not be converting dates to this format or pushing this other than recommending it here.

The best date format is the [http://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format. It looks like this: '''2012-11-27''', compare this to '''02/04/03''' which has three possible interpretations.

The reasons it is best are:

* it is unambiguous.
* it sorts correctly using string or numeric sorting.
* it is a formal standard.
* it is widely used.
* the format can also be used to represent precise date and time, with timezone information.

see also: http://www.w3.org/QA/Tips/iso-date

==Other Skills==
I do have some other skills that may be useful to the OSE. I am an experienced data munger, if you need scripts written to process and convert data feel free to drop me a line. Things like

* Writing cron jobs
* Talking to databases (postgres/mysql/sqlite)
* Pulling in xml,yaml,json,html,csv,wiki markup
* Spitting out xml,yaml,json,html,csv,wiki markup
* Talking to REST web services.
* Screen scraping and web automation.

My language of choice is perl. My collaboration method of choice is [https://github.com/donovan github]. My development environment of choice is ubuntu. My server environment of choice is ubuntu/debian.

Complex conversion templates are available from other media wiki sites eg: http://en.wikiversity.org/wiki/Template:Convert. This system is very comprehensive http://en.wikiversity.org/wiki/Template:Convert/list_of_units but is quite complex and requires subtemplates. I have done a proof of concept with temperature conversion:

* <nowiki>{{convert|60|°F|°C|sigfig=3}}</nowiki> = {{convert|60|°F|°C|sigfig=3}}
* <nowiki>{{convert|16|°C|°F|sigfig=3}}</nowiki> = {{convert|16|°C|°F|sigfig=3}}

If OSE wish to use these templates I suggest following the instructions at http://www.mediawiki.org/wiki/Help:Templates#Copying_from_one_wiki_to_another, this will be much easier for someone with import rights on the OSE wiki (I do not have these rights). Without import rights each subtemplate needs to be copied manually which is tedious and is prone to cut and paste errors.

===Wiki standards===
Standards like the [[Date_Format_Convention]] are important in a wiki, they create consistency, help define a framework within which people can become more productive and in general help to make the wiki more functional. As such I will be editing peoples Logs, please let me know if you would prefer I left them alone.

===Date formats===
I have a definite opinion about what the best date format is but I will not be converting dates to this format or pushing this other than recommending it here.

The best date format is the [http://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format. It looks like this: '''2012-11-27''', compare this to '''02/04/03''' which has three possible interpretations.

The reasons it is best are:

* it is unambiguous.
* it sorts correctly using string or numeric sorting.
* it is a formal standard.
* it is widely used.
* the format can also be used to represent precise date and time, with timezone information.

==Other Skills==
I do have some other skills that may be useful to the OSE. I am an experienced data munger, if you need scripts written to process and convert data feel free to drop me a line. Things like

* Writing cron jobs
* Talking to databases (postgres/mysql/sqlite)
* Pulling in xml,yaml,json,html,csv,wiki markup
* Spitting out xml,yaml,json,html,csv,wiki markup
* Talking to REST web services.
* Screen scraping and web automation.

My language of choice is perl. My collaboration method of choice is [https://github.com/donovan github]. My development environment of choice is ubuntu. My server environment of choice is ubuntu/debian.

Donovan: /* Current objectives */

==Introduction==
My name is Donovan Jones. I am a software developer from New Zealand. I am a competent wiki editor and plan to assist the OSE in this capacity. I do not plan to collaborate or assist in other ways in the medium term. Essentially I am a [http://en.wikipedia.org/wiki/Wikipedia:WikiGnome WikiGnome], as such it is probably safe to ignore me.

If you don't like some of my edits please let me know on my talk page, I don't want to step on any toes, but I'm not going to seek approval for every edit. On aggregate I hope you will agree I am improving the wiki, so let me know when you feel I am not.

==Current objectives==
* '''MJ request''' - [[How_to_Create_Frames_and_Windows_in_Media_Wiki]] for Flashy XM, Flash Mob, and other pages.
** investigate support for widgets on ose wiki, if available try: http://www.mediawikiwidgets.org/Iframe
* [[Wiki_instructions#Style_Guidelines|Improve metric support]] on the wiki.
* Work on [[Work_Log_Guidelines]] particularly the [[Date_Format_Convention]].
* Work on and improve [[Special:Categories|categories]].
* Wikifying pages: work on wiki linking.
* General grammar and spelling fixes.

==Future objectives==
* Collaborate with my father to contribute on Biofuels particularly [[butanol]].
* Creating custom wiki templates
* Creating custom OSE infoboxes
** keep any eye on http://meta.wikimedia.org/wiki/Wikidata which will make creating infoboxes much easier.
** software infobox to include:
*** licence
*** ubuntu package name

==Thoughts==
As an outsider there are a few observations I would make about things that could be improved.

===Support for the Metric System===
Three countries use non-metric measurement systems: Liberia, Myanmar, and the United States. I believe for OSE to a have a global impact it needs better support for the metric system. Many collaborators will only be able to source metric parts. I want to help provide better metric support at least on the wiki.
====Using Conversion Templates====
Complex conversion templates are available from other media wiki sites eg: http://en.wikiversity.org/wiki/Template:Convert.

Point To Peer

2012-12-02T00:59:16Z

Donovan: /* Examples - please fill in here */

{{Template:Category=Wireless mesh networking}}

=The Theory=

We propose that the development of a peer-to-peer internet and communications infrastructure, delivered essentially '''at cost''', is feasible today. It is merely a question of organization to get it implemented. Regulatory and structural barriers are likely to crumble via wide, popular support.

=Existing Problems=

Today, the internet and communication backbones are controlled by centralized interests. This does not favor a long-lasting democratic environment for human communication.

=Proposed Way to Apply the Theory=

We aim to test our theory (feasibility of P2P, physical communication infratructure) by building the infrastructure for peer, decentralized internet.

The core of a peer-based internet system proposal is the building of a physical infrastructure, where internet service is delivered at-cost. Such an infrastructure may be implemented most easily via a network of wireless towers. User nodes store content in a distributed fashion.

Key technical issues are:

#Development of communication and storage protocol based on peer-to-peer strategies
##Storage on peer computer nodes
#Building of wireless emitter/receiver nodes
#Building towers
#Powering wireless nodes

Key social issues:

#Organize a large support base of future user owners simply by concerted effort and by sustaining focus
#Attempts to stop this by the centralized power system can succeed only if people support the centralized power system, with its higher costs for internet and communications systems. This is unlikely to happen by simple dollar and cents arguments.
#Breakthrough application of [[User Owner]] concept.

=Related existing work that verifies feasibility=

*Paul is working on a protocol for decentralized communication.
*Marcin is working on solar energy production, circuit fabrication, aluminum production.
*Sam can align a wide support base for getting the proposal funded directly by stakeholders.
*Natural law: all empires crumble after some time

==Development Team==

*Marcin Jakubowski
*Sam Rose
*Paul B. Hartzog
*Keith Smith

==Infrastructure==

*[[PeerNet]]

=Related existing data or facts that support theory=

* The [[User Owner]] concept
* Various un-money, free internet, free communications, and related efforts

** ~$99 all FOSS, hardware is Open Source

=Existing constraints and barriers to deployment=

*Costly off-grid energy systems
*Regulatory issues in communication infrastructures
*Land base for setting up towers
*Peer to peer communication protocol
*Peer to peer data storage
*Cost of erecting towers
*Opposition from centralized interests

=Facts and data that support arguments against=

Centralized control of information efforts include lawsuits of the Motion Pictures Association, Recording Artists Association

=Relevance to OSE core values=

Decentralized and effective provision of needs is essential to OSE's philosophy.

----

=Implementation=

#Development of communication and storage protocol is a tractable problem
#Capitalization may be obtained readily by involving a large number of internet users, paying perhaps $25/year or whatever the at-cost price may be
##1 node every 10 miles, or every 100 sq miles (ex: 30,000 nodes for 3M sq miles of the USA
##Assume 10M initial subscribers- $2.5 billion in startup revenue available
##Each node has $100k allotment available

=Strategy=

Cost reduction for a project of this magnitude is feasible. $100k/node provides for feasibility using off-shelf technology. However, we want to go for open source components to assure maximum value. I propose we use $1-10M to develop open source, at-cost production facilities for hardware:
*wireless nodes - via CNC routers
*mobile, onsite aluminum production for towers from on-site clay - '''feasibility has not been evaluated'''
*open source protocol and code
*open source solar concentrator or OS PV production (ribbon PV is an immediate candidate)
*storage battery production - sealed lead acid
*power electronics - inverter and power conditioning for tower

[[Category:Zero_Hour]]

=Project Status=

*Zero Hour began at 5 PM, Wednesday, February 26, 2008
*Initial business plan to be drafted by March 26, 2008
**Due diligence required: dedicated email list, publicity via networks
**Dedicated webspace; opensourceecology.org volunteered at present
*Refined business plan to be drafted by April 26, 2008
**Due diligence required:
***Economic feasibility of mobile aluminum smelting unit
***Economic analysis of node hardware fabrication
***Economic analysis of solar energy production
***Economic analysis of energy storage production
*Final business plan to be drafted by May 26, 2008

==='''WHY''' are you motivated to support/develop this work?===
*''Do you endorse open source culture?''
I am a socialist to the core.

*''Why are you interested in collaborating with us?''
Because I am a socialist to the core.

*''How do you think that the GVCS can address pressing world issues?''
By thinking small, local and sustainable. The most important human occupation is acquiring food. The elite know this and have all but taken over (global) food production (if you control a population's food you control that population).Food security must be the responsibility of each individual and the way to help this happen is to facilitate food production on a human scale.

*''What should happen so that you become more involved with the project?''
A small amount of discussion quickly followed by building stuff.

*''What are you missing in the project?''
Both of the above . . .

*''What are your suggestions for improvement of the project?''
I will pass my comments along as they arise.

==='''WHAT'''===

*''Are you interested in being part of the world's first, open source, resilient community? The GVCS is the preparatory step for the OSE Village Experiment - a 2 year, immersion experiment (2013-2014) for testing whether a real, thriving, modern-day prototype community of 200 people can be built on 200 acres using local resources and open access to information? We are looking for approximately 200 people to fill a diverse array of roles, according to the Social Contract that is being developed. This may be the boldest social experiment on earth - a pioneering community whose goal is to extend the index of possibilities regarding harmonious existence of humans, ecology, and technology - as a beacon of light to benefit of all people on Earth.

Chicken processing

2012-12-02T00:17:59Z

Donovan:

{{Breadcrumb|Food and Agriculture|Animal Husbandry}}
Grab by feet and hold upside down

wait until chicken calms down from too much blood in head

hang feet by rope

either cut throat when chicken is calm and will flap around or swing chicken until dizzy and then take down and chop throat, the chicken will not flap as much

hang chicken until all blood is out

blood goes bad very quickly so you want the blood out soon

dip chicken into really boiling water

scrape feathers off with fingers, very small feathers/hairs can be burned off with torch or fire

take bone or something out of throat area

there are two bad areas in the chicken that need to be removed, the scent gland at the tip of the tail taht is very smelly, cut it out in a triangle and cut it out. the gall neds to be removed, cut to left and right of anus, grip anus shut and cut around to allow removal of intestines, if it wont come then cut around the neck. The lungs, liver, and kidneys will stick to the back of the rib cage and have to be scraped out.

check intestines for what you want to eat and if there is anything bad, look at them, check for worms, flukes, cyts with eggs inside.

3 buckets, one for hot water, one for cold for cleaning, and one for throwing all feathers and stuff into buacket and bury

preserve chicken:

salt and hang, get salt in near bone,

smoke chicken, hang in smoke until really done

<br/>

==='''WHY''' are you motivated to support/develop this work?===
*''Do you support open source culture?''
Absolutely. We have to open so many things - software, hardware, knowledge, connections, beliefs, feelings. Just amazing possibilities!

*''Why are you interested in this work?''
First, Open Source Ecology is based on Natural Principles which consequences have been shown to be positive for a lot of natural and technological systems.

* Decentralization (instead of Centralization) of Power – proven pattern in a lot of networks, like technology (internet, web site development, …) and human relationships (politics, religion/spirituality, family, …).
* Self-Sufficiency – basic needs for living are covered and produced by the local people. No need for dependence. In the future if there is dependency it will be in the form of collaboration.
* Openness – sharing documentation, product design and development process. Being able to change and adapt the products.
* Product Quality – life-time, modular and systems Design.
* Collaboration (instead of using other people for self-interest) – getting people together by purpose and values, and not by force, is much better for the producers and the consumers as well.
* Replicability – giving birth of open sourced, modern-living villages is just amazing! Having the choice of replicability saves a lot of time and work.

Second, it is crucially important that we go beyond life of survival. Survival mode is pushing everyone to take resources from other people, not considering their allowance, health and their community. When we are in survival mode we often neglect our own values and push other people in order to survive.

When we reach the state of living where all basic needs are covered, every person on this planet will have much bigger possibility to develop his own potential. Right now only a very small percentage of the human population have the time and possibilities to develop themselves – to guide their own life in the direction they want, to contribute to the society by using their abilities in their fullness. Most people in the world are fighting, struggling, working only for their own survival or that of their own families, and higher goals and desires like developing themselves and contributing to society are not possible or of low priority.

We need new models of economy and living based on openness, giving and sharing. Open Source Ecology is headed clearly in this direction, giving back freedom and abundance to where it belongs.

*''Why are you interested in OSE Germany?''
OSE Germany is crucial to the development of OSE in Europe. If we do it in Germany we can do everywhere in Europe. Germany has many advantages: a lot of professionals, one of the biggest sustainability cultures in the world and most people are well financially.

*''How does OSE fit into your current live and long and short term goals?''
I have dedicated my life to OSE.

*''What will stop you supporting OSE Germany?''
Nothing. As long as we are developing with the OSE values and principles, this is my path.
<br/><br/>

==='''WHAT'''===
*''List all of your skills in these areas: Communications - Organizational - PR/Marketing - Computer Support - Finances - Law - Design - Video/Graphics - Education - Architecture - Construction - Natural Building - Ecology - Agriculture - Permaculture - Renewable Energy - Electronics - Automation - Metallurgy - Engineering - Product Design - CAD - Fabrication - Industry - CNC - Chemistry - Others''
'''Communications'''
- I share valuable information openly - blogging, speaking, presenting, discussing, clarifying, creating and sustaining bridges.

'''Organizational'''
- Experience in organizing OSE Europe, Bulgarian open sustainability network and OSE Germany.

'''Computer Support'''
- I use open source software: Ubuntu, Wordpress, Wiki, phpBB, Drupal. Able to setup quickly Wordpress websites.

'''Video/Graphics'''
- I use Kdenlive, GIMP and Inkscape.

'''Education'''
- Love it. For education to effective, there should be clear understanding of the teacher and clear simple communication.

'''Natural Building'''
- I want to learn and practice designing and building tools and structures.

'''Permaculture'''
- Basic understanding, would love to get practical experience and grow my own food.

'''Renewable Energy'''
- Basic understanding, would love to get practical experience.

'''Electronics'''
- Played with Arduino.

'''CAD'''
- Beginner in Solidworks, seems easy and fun.

'''Fabrication and CNC'''
- Beginner welding, metal working and CNC experience through few courses. Found it easy and will be happy to improve my fabrication skills.

*''What have you contributed to the development of OSE and OSE Germany?''
To OSE: Wiki ([[Crash Course]], [[Team Culturing]]), IT, [[Press_Procedure|Press]], [[OSE Europe]]<br/>
To OSE Germany: Organizing, communicating, expanding the network, finding people. For more info see [[OSE Germany]].

*''What is stopping your contribution to OSE Germany?''
On a personal level: my communication is expanding and I am prioritizing where my attention and work is going. I am deciding between good, better and best. I am not yet so good as I wished I was, but I am getting there every day. I want and I am learning how to be more effective.<br/>
On a team level: team communication and team work should be better. This has direct effect also on my work - delaying or improving it. Would love to see more people engaged in OSE Germany from the hearth.<br/>
On environment: we still don't have a real [[Germany/OSE Village|OSE Village]] where we can take ownership of our lives and work.
<br/><br/>

==='''HOW''' can you help?''===
*''How do you want to contribute?''
1) Developing [[OSE Germany]], 2) creating open collaborative [[OSE Europe]], 3) helping OSE and FeF as I can.

*''What is the best use of your time?''
'''Communication''': I love communication that is clear, immediately gets to the point, time-saving, but also also honest and from the heart. Feedback is great!<br/>
'''Prioritized Actions''': For OSE Germany it is better that my focus right now is finding the people with skills rather then me personally developing my engineering, fabrication and construction skills, i.e. organization and communication. Second priority is the creation of [[Germany/OSE Village|OSE Village]] as long-term dedication.

*''Can you volunteer to work with us, and if so, how many hours per week?''
All my time!

*''Are you interested in working with us for pay? If so, what services can you offer, and what is your hourly or per-project rate?''
We have to find ways to sustain everyone of us involved in OSE. Be it through money and other ways, the projects should be long-term sustainable.

*''Would you like to see yourself working with us on a full-time basis? Under what kind of conditions?''
Yes. Under the only condition that we make it possible at least for the OSE Germany Core Team to work sustainably in the long-term.

*''Are you interested in being part of the OSE Village in Germany?''
Absolutely! This is my long-term goal.

*''Are you interested in building GVCS or other Open Source Hardware equipment? If so which ones?''
Totally. Still too early to say which ones, depends on our needs in the OSE Village.

*''Are you a [http://openfarmtech.org/index.php?title=True_Fans True Fan]?''
Yes.

*''Are you OSE Germany Commons Donor?''
It is not possible technically yet. Hopefully we can offer this possibility soon.

*''What should happen so that you become more involved in OSE Germany?''
[[Germany/OSE Village|OSE Village]] in Germany.

*''What should happen so that you are passionately involved in OSE Germany?''
I am and if more people are passionately involved in OSE Germany, then the synergy is amazing and the passion multiplies!
<br/><br/>

===Team Work and Network===
*''What are your expectations of your team members?''
They love the OSE values. Are honest with themselves and others. They work focused on what is important for our development. Communicate relevantly and openly. Communicate immediately when they feel that something planned is wrong or cannot happen. Give feedback. Choose to unite rather than separate people. Maintain enriching relationships within the team. Finally they want to develop themselves and help other people even outside the team.

*''What do you perceive as your responsibility as a team member?''
All of the above expectation of my team member + ensuring that we as team are moving forward.

*''What do you think should be our priorities now and in the long-term?''
Now: 1) Better team work 2) Expanding the network 3) OSE Village<br/>
Long-term: Still to be defined concretely with the team. My initial thoughts: 1) Identifying economically significant technology for Germany (GVCS-like) 2) Creating Open Collaborative Platform 3) Development and proof of concepts for few technologies 4) Creating dozens of places where open source development thrives 5) More Growth and Open Collaboration

*''What are the biggest challenges for OSE Germany and what can we and you do about them?''
For Germany as a country: a lot of laws (Gesetze) and certification requirements. Solutions: learn about them and find out solutions as open community.<br/>
For the team: good strategy and dedicated actions. Solutions: Strategy is yet to be defined, all help is needed. Dedicated action really depends on your real motivation to participate in OSE Germany - the more clear you are the better for you and everyone.
<br/><br/>

===Your Friends and Community===

*''How are your friends and environment supporting open source development''
Almost all my friends and my environment participate in OSE and [http://openom.eu/ OM]. Both represent exactly the way I want to live. Though, I need also physical environment, like the OSE Village in Germany, so that I and others can put the open source development into concrete practice.

*''How your environment can become more supportive or even engaged in open source development?''
Experiment and become an example that it is possible. Create physical places where these people can live and work. Make it sustainable in the long-term.

*''Can you share with everyone of us friends, people, communities and organizations you know who are already doing valuable work for a better future?''
I document it here: [[OSE_Europe/Friends|OSE Europe Friends]].
<br/><br/>

===Feedback===
*''What do you like in OSE Germany?''
The people who are already participating and the growing interest. That we are open network. That we have very similar values.

*''What is missing in OSE Germany?''
- More dedicated people.<br/>
- Real need! OSE Village and visionary project.

*''What are your suggestions for improvement in OSE Germany and how could these be implemented?''
Know what you really want to do. If OSE is some part of that, join us!

* Happy to provide later upon request—would prefer to know you’re interested before I impose on their time, and so I can give them a heads-up closer to the actual time you would contact them.
; 4. How did you hear about the program? Why are you applying for a Dedicated Project Visit? Why are you interested in our work?
* Initially heard about it via TED a number of months ago and was interested but not at a point when I could consider playing a role. As fate would have it though, I recently came across it again in the article published by MAKE magazine—which was the catalyst that inspired me to action.
; 5. Describe practical skills you may have - from agriculture, workshop, industry, organizing, hands-on, CAD, manufacturing, computer skills, etc.
* '''Practical Skills'''
** ''Agriculture:'' was raised in gardening family, many years experience with growing food and learning much about the science/chemistry behind optimal growth.
** ''Woodworking:'' moderate skill, and eager to learn more—recently built compost bin and a boardwalk for a trail overtop a swamp
** ''Cooking:'' have cooked most of my life. Can cook almost any recipe successfully and love doing it. Have built a fair-sized repertoire over the years.

** ''Circuitry:'' recently acquired an Arduino and have been playing around with it, but my skills and knowledge are limited in that department. Would love to learn more though.

; 6. Have you designed and built or produced anything for your own use?
* In terms of wood-working, this past year I have designed and built my own raised garden beds, compost bin, trail boardwalk (through a swamp), and laptop stand.
* I’ve also made myself a set of dishware from a few years spent studying ceramics
; 7. Which of your skills are particularly relevant towards creating the GVCS? Please view the TED Talk and recent update for the latest on our approach and on-the-ground work.
* The skills that would be relevant depend on the role you most need filled. I would be happy to discuss this more.
; 8. Do you have any organizational skills and experience?
* Yes. I am well experienced in scheduling and event planning, and am familiar with most tools used for that purpose.
; 9. Can you cook? Can you cover your food expenses?
* Absolutely. I know a wide range of recipes by heart and can pretty much follow any other. My guacamole, while not worth dying for, has actually caused at least one fight.
; 10. Do you have resources to support yourself while volunteering with us?
* Yes. I have all the funds, transportation, and even shelter, that I might need.
; 11. Do you have any medical, physical, or psychological conditions or disabilities which may affect your ability to do physical work?
* No; I’m fit and healthy.
; 12. Do you have any emotional, psychological, or mental conditions which may affect your ability to act with composure and good judgment?
* No. Clean bill of health.
; 13. Are you easy to get along with and can you get along with other people?
* Definitely easy to get along with; happy to find a middle ground on conflicts that arise. Not the social center of a room, but am certainly amicable and enjoy shooting the breeze and learning about others.
; 14. Do you have strong ideological views (political, religious, elitist, feminist, etc.)?
* Mostly moderate view on all of the above, and I certainly do not proselytize and generally do not judge others for differing belief—it takes all types to make the world turn.
; 15. Are you a team player - or someone who understands that the work we do at Factor e Farm is for a much greater purpose than for our own self-gratification, indulgence, or agenda? This implies a level of maturity in the participant which allows one to remain not only aligned with the vision, but also to remain motivated in this work.
* Yes, I am a team player. Working with such a team towards the purpose of Factor e Farm’s mission is my driving motivation for signing on.
; 16. Do you smoke?
* No, but I don’t condemn others for doing so.
; 17. Do you have any dietary restrictions? Will you eat meat raised at our farm?
* None, and yes.
; 18. Do you have transportation? Will you be arriving by car and leaving the car on-site?
* I do have a car, and will be happy to use it to help the project if it’s needed.
; 19. Documentation is key to moving our work forward. Are you familiar with using a Wiki?
* Yes.
; 20. Can you work well as a pioneer under rough conditions, by taking the responsibility to create your own environment?
* Yes, and I would be happy to do so.
; 22. If you are accepted and things don't work out, do you have other options to pursue after the month?
* Yes—I can go back where I came from (with a heavy heart) and figure something else out.
; 23. Are you willing to publish all the results of your work openly, and to make any of your contributions open source, consistent with our goal of creating Distributive Enterprise?
* Definitely.

; 24. How does your proposed work contribute to the creation of the GVCS?
* I could help by documenting all the projects being currently undertaken. I can video-record as needed, update the wiki with relevant information and documents concerning the projects and the organization as a whole. I could prepare graphics and visualizations. I could conduct interviews and write press releases.
* I could work assisting with financials and quantitative modeling as needed, as well as strategy or planning/organization. I could also help with whatever GIS/mapping needs you might have. If any of that sounds like something you could use help with, it would be easier to talk more about specifics via telephone, email or Skype.
* I could serve as cook for the members of the Factor e Farm. I’m not sure if it is currently every man for them self or if everyone pools money for food, or something else, but if meals are collective, I could help prepare and plan them.
* I could work as a farm helper, helpful hand to prototypers, or construction. Planting, harvesting, making, building—depends where I’m needed most.
; 25. What are the metrics by which you could assess the success of your work? (prototypes built, documentation produced, resources or funding raised, infrastructure built, food provided, contribution to the community provided, True Fans recruited, etc.) Note that we are looking more for tangible and explicit proposals and results as opposed to 'I will help with whatever is needed' or other generalizations - unless we agree otherwise.
* While I did just generalize with my last bullet point in #24, I think my prior three proposals are fairly specific. The metric for success on any of the three would, naturally, vary greatly. Consequently, I would appreciate knowing which you were most interested in before detailing intended results
; 26. What do you expect personally to get out of your Dedicated Project Visit?
* The chance to contribute to a project that could possibly change the world.
* The feeling of gratification from working toward a fantastic dream.
* Whatever knowledge/skills I can pick up from those around me.
* Speaking and spending time with all the interesting people who have come to help make this a reality.
; 27. Can you visit us prior to your Dedicated Project Visit?
* If it seemed likely I could join and help, then yes, I could likely make the time before my arrival to visit.
; 28. Please share three interesting things about yourself.
* I lived at and served as a volunteer at Devils Tower National Monument for a summer; working with fascinating people and discovering a love for rock climbing.
* I have a passion for analog photography, and the many technical intricacies involved with both the cameras and the darkroom.
* I spent my first two years of college in a tiny 400 person school outside of Santa Fe living, breathing, studying and discussing the primary source works of history’s greatest thinkers.
; 29. Please share three things you think people should know about living with you.
* I might resent you a bit if you snore.
* I’m happy to make the meal, as long as you help with the dishes.
* I love trying and exploring new things, so don’t hesitate to bring me along or introduce me to whatever.
; 30. Can you bring a digital camera or phone camera for documenting your work?
* I can bring a digital camera, and/or Flip video recorder.
; 31. Any other concerns or considerations?
* The only consideration I can think of is that since I’m so eager to help, the sooner you can respond, the better.

Documentation Standards

2012-12-02T00:03:39Z

Donovan: /* Links */

=Introduction=
As the project moves towards viral replication, it is important to create effective documentation standards. The scope of Open Source Ecology involves machine and organization level items leading to the Open Source Economy. In Phase I (January, 2013), we are defining the standards for the 50 [[GVCS]] machines, which is intended to be a beta test for a larger platform that scales to any number of items - encyclopedic scope. Organizational aspects for creating the open source economy will be developed in Phase II (February, 2013).

=Design Rationale=
The scope of effective documentation standards for OSE includes Machine, Organizational, and Wiki level areas of documentation.
==Organizatinal Level==
*The organizational level involves documentation related to running a GVCS-based development, production, or other applied project.
*Enterprise development documentation.

==Machine Level==
*Understanding the standards makes it possible to navigate both graphically and via the address bar on the OSE wiki - to access any piece of documentation for any machine.
*Machine naming is standard. Currently, the names used on the main site at opensourceecology.org are used.
*Each machine has a Core and Supporting documentation set. The Core set includes those pieces of documentation that are indispensible for the safe and effective building and usage of GVCS tools by inexperienced builders/users. Supporting documentation is that which allows for the modification, remixing of modules, and other hacks on the machines. It also includes that information which makes replication easier, but which is not critical to such replication - by a novice builder.
*Each Machine has a finite, well-defined set of Core Documentation and Supporting Documentation.
*Supporting Documentation consists of Wiki-level (such as Links section or Index) and Machine-level items (such as CAE analysis - noncritical but desirable for replication)
*Standards are consistent with [[Open Source Hardware Association Open Source Hardware Definition]].

==Wiki Level==
*Each machine has a particular set of wiki-level Supporting Documenation items - such as Links (example below). Standards are defined for each of these Supporting Documentation item

Hall Effect Sensor Module

2012-12-02T00:02:19Z

Donovan: /* Action Info */

=Introduction=

Note: newer sensor design consists of a 0.5"x1.5"x6" long alluminum bar upon which the Hall effect sensor is mounted.
==New Sensor Holder==
Installed on CEB Press. Adjustable for proximity to magnets, and up-down adjustable via clamp mechanism. Threaded rod is 3/4", and 2 bolts hold it firmly in place. Known bug: clamp mechanism around frame needs to use 2 - not 1 - bolts for clamping, otherwise rotation around bolt exists.

22 AWG Stranded Wire of different colours

Cord jacket for 3 22AWG wires

Wire Label (Important! Label your wires so you know which wire is connected to which pin- it'll save you a lot of trouble later on!)

----

Steps

*Cut 1 piece of aluminum flat bar to length (ex. 10cm)

*Cut 3 pieces of 22AWG wire and 1 piece of jacket to the desired length (ex. 150cm)

*Strip the 3 pieces of wire 10mm at one end and 20mm at the other end

*Check and confirm which pins of the hall effect sensor are to which inputs/outputs (ex. V+, V-, Signal) see [http://www.sparkfun.com/datasheets/Components/General/Hall-US1881EUA.pdf datasheet]

*Solder the 20mm ends of the wires

*Solder and shrink tube the 10mm ends of the wires to the hall effect sensor pins

*Recheck which wires are connected to which pins

*Attach a label near the sensor to each wire about what the wire's pin is (ex. Red is V+, Black is V-, Green is Signal)

*Clamp or weigh down the wires near the sensor so that the sensor is stationary

*Position the aluminum flat bar underneath the sensor. The sensor should be near an end of the flat bar, the sensor's wire output parallel to the bar and inward toward the other end of the bar

*Apply silicone to the sensor and its pin-wire connection. The objective is to mount the sensor to the aluminum while waterproofing the pin-wire connection.

*Insert the 3 long wires into the jacket

----

Testing

Upload the following code into the [[Arduino]] microcontroller then check the serial monitor for the signal from the hall effect sensor (SignalValue/1024 being the fraction of 5V)
