==Overview==

[[LifeTrac]] is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies.

Featuring a modular design and detachable [[PowerCube]] units, it has the ability to rapidly switch between a variety of GVCS machines via the [[QA Plate]]. The machine is overbuilt with a focus on lifetime design and ease of repair.

Four hydraulic motors provide skid steer power to the wheels, and a unique chain tread system enables navigation of fairly extreme terrain.

Induction Furnace/Research Development

==Overview==
Research in creating the [[Induction Furnace]] with the goal of creating a design that fully complies with [[OSE Spec]].

Project management site: http://openpario.mime.oregonstate.edu/projects/osif

==Introduction==

The Open Source Induction Furnace Project seems to be the most promising way to implement the [[foundry]].
This project involves the design of:
* a high-power induction furnace circuit (between 20 and 50 kW), and
* the melting chamber proper.

Well, we could buy a turnkey system perhaps for $5k total used, and run it from the LifeTrac generator. The only disadvantage to this route is that if it breaks we’re dead-in-the-water – either with the impossibility of fixing closed-source technology, or a high repair bill. A single component which blows and is inaccessible for fixing could in principle turn a working power supply into worthless junk. Thus, it is worthwhile to tame this technology by open-sourcing the design.

==Goals==

To fulfill our [[foundry]] goals,
The furnace should have the following characteristics:

#Induction furnace or any other technology that can do this within a budget of 20 kW of electric input, with minimal pollution
#Suitable for melting all metals and alloying
#300 lb per hour steel melting furnace for casting
#240 v ac, 20 kW power source available

==Conceptual Diagram==

This is a conceptual diagram of the entire Induction Furnace system from the [[Global Village Construction Set]]. The furnace is powered by 20 kW of 240VAC electricity from the [[LifeTrac]] generator. The entire system includes the power electronics, induction coil, and heating vessel - into which metal for melting is inserted. This diagram intends to document the relationship of functional components in the induction furnace system, as a basis for technical development of components and their integration.

The electronics part should be adaptable to different metals and different metal melting coil geometries. Melting coils should also be modular, such that the power electronics can feed different coils. Basic functions include selection of heating frequencies, which are required for melting different metals or metal geometries. There should be a feedback in the electronics, where the amount of power given to the coil should match the quantity/geometry of metal being melted.

[[Image:induction_concept.jpg]]

==Details==
The complete design should include all of the following:

===Induction Furnace Circuit===
# Scalable from 20 up to 50 kW in units of 1 or 5 kW
# Allows for power and frequency selection
# Power source may be either 1 or 3 phase electrical power

===Heat Dissipation System===
Specifications of a cooling or heat dissipation system.

===Coil===
# Modular, adaptable design specifications for primary coil windings

===Melt Chamber===
# Geometical design of melt chamber and basic power transfer calculations
# Should include provisions for loading and pouring
# Given our goals, which is best: a coreless or a channel induction furnace type [http://www.wisegeek.com/what-is-an-induction-furnace.htm] ?
## channel: useful in the melting of lower melt temperature metals; less turbulence at the surface.
## coreless: stronger stirring
# Pouring: manual pouring methods are more suited to low volume production lines.
====Crucible====
* See: Crucibles for Induction Melting - Guidelines for Selection and Use: http://www.engineeredceramics.com/crucible.htm

===Other Considerations===
# Complete bill of materials
# Fabrication files for circuit and other components
# Sourcing information for components
# System design and process flow drawings

==Notes==
===Benny===
I just read that you plan to build up an induction furnace. That´s a an interesting and exciting plan.While reading the article some remarks came to my mind.

But before I want to introduce myself:

I am Benny from Germany, Hannover.
I am diploma engineer for electrotechnology and working at the university. I am dealing with some induction heating/ melting applications like induction melting of glasses (that is possible!) and induction furnaces for cast iron.

Some remarks from my point of view:

# It is possible to build up a low cost furnace with the mentioned parameters.
# The frequency of 9,6 kHz is much to high. The efficiancy will be so bad, that it will be hardly possible to melt steel or iron. Due to the small penetration depth of about 2 mm with this frequency and this electrical resistance. So it needs a really small diameter of the crucible, and thats not helpful. Also the refractory material will be strained too much, so that a small lifetime is given. This will raise the cost for the operating.
# 50 Hz or 60 Hz is a better solution. And you can save the cost for the hf-converter.
# How much material do you want to cast at one time? The maximum, what i expect to be possible with 50 kW will be about 50 to 60 kg.
# What kind of raw material should be charged? It is important for the starting, because the initial density should not be too small (packing density). And the other question is, what kind of scrap it will be.
There are so many problems known with content of zinc (hot zinc dipped) and other materials. The lifetime of common refractory material is really small. And what is more important the security for the personal is not given without a strong exhaust system, due to the toxic steam. I expect this as a strong cost factor.

Jonas Anderson:

{{OrigLang}}
{{Breadcrumb|Wiki}}
{{RequiredReading}}
{{tip|Helpful Reading|The '''[[Crash course on OSE]]''' page will help you understand the underlying intentions for the OSE Wiki so that your contributions can be as meaningful as possible.}}

{| align="right"
| __TOC__
|}

A wiki is a place where a large number of people can contribute to content generation and organization.

The critical point about a wiki is that '''it can be used as a repository for a large amount of information which can be organized later'''. We encourage you to internalize this point and start using wikis as a place where human knowledge can be collected, and value can be added to that knowledge by further organization towards applications.

== Policies ==

In the ideal situation, a large messy hairball of input is organized into distilled, high-quality content. A successfully-implemented wiki has the capacity to self-organize under the guidance of clear procedures in the hands of wiki moderators; with this in mind, please make sure to familiarize yourself with these procedures as expressed in the following policies:

* [[Wiki Login Policy]]
* [[Wiki Transparency Policy]]
* [[Wiki Curators]]

== Content ==

There is a wide scope of things that can be included in the wiki - anything related to '''healthy, sustainable living, open source technology, good human relations, human empowerment, etc'''. OSE is about the integration of humans with technology in a benign way, with a focus on open source techniques. That's just about all under the sun that was historically proven to be worthwhile. Please be careful to keep this in mind while editing.

The wiki is designed to be a 'braindump' - please follow standards when adding new information per the Wiki Reorganization of 2011. Short entries, or stubs, are acceptable because they can be used as a definition later - even if nothing links at present. The expression ''braindump'' should not suggest a low level of quality; bad content to a Wiki is like bad nutrition to a body. If the Wiki is supposed to stay healthy, then a certain level of quality is essential.

Most of all, bad content, which is usually added by non-experts, discourages the distinctive experts from contributing. Everyone is urged to double-check his/her contributions, paying attention to respect, motivation towards others, accuracy and general quality. Both the motivation of positive contributors and the discouragement of negative contributors through content qualification is probably the strongest driver in wiki quality management.

The OSE Wiki-contents are different from typical wikis because the focus is narrowed to the support of OSE, with this difference in mind, a concentrated OSE Wiki can be built that serves its purpose.

"A Wiki is only as good as the search process is quick". It is a useful practice to examine the main wiki concerning any topics before starting an article.

=== Advertisement ===

There shall be '''no''' advertising on this wiki. Sourcing information and product reviews are allowed, as long as they are directly related to the creation of [[Distributive Economics]].

== Style Guidelines ==

* The first sentence of an article should be a one-sentence summary of the whole topic
** The next paragraph should be a longer summary of it
** Then go into details
* Be direct and practical
** Avoid acronyms, jargon and neologisms (or words like ''neologisms'', which most people do not understand)
** Never use a long word or phrase where a short one will do.
** If it is possible to cut a word out, cut it out.
** Never use the passive where you can use the active (e.g. say "We built the house on Tuesday" rather than "The construction of the house took place on Tuesday".)
** Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
** Break any of these rules sooner than say anything outright barbarous.
* When writing about measurements, list both imperial and metric values. List both Fahrenheit and Celsius for temperatures.

== Searching ==

You can search for content by typing your search terms on one of the '''search boxes''' at the '''top left corner'''
* The '''first search box''' will search for text matches on '''this wiki only'''
* The '''second search box''' will perform a ''custom Google search'' on '''this wiki''', on '''our [http://blog.opensourceecology.org/ blog]''', on '''our [http://forum.opensourceecology.org/ discussion forum]''' and '''other related sites''', like ''Appropedia''.
** For more details, see the page about the [[OSE custom search engine]]

{{Tip|Search before creating a page|
Articles on our wiki should be cross-referenced against articles on [[Special: interwiki|neighboring wikis]] (like ''P2P Foundation'' or ''Appropedia'') to avoid re-inventing the wheel any more than we have to.
So, before creating a page, use the ''second'' search box to see if there are any existing articles on related wikis. If so, creating a link to it may be better than creating a new page, unless the existing page on the other wiki does not contain enough information.

Articles from any wiki listed at [[Special: interwiki]] can be linked to by using the value at the ''Prefix'' column, like this:
'''<pre>[[Appropedia: Comparison of electrical motors]]</pre>'''
which creates this:
[[Appropedia: Comparison of electrical motors]]
}}

== Logging In ==

{{Info|Log in first!|Before creating new pages or editing existing ones, you have to '''[[how to get a wiki account|log in first]]'''.}}

Any person contributing to the project in a substantial way should fill out the [[Team Culturing]] survey, and therefore, any name should be linkable with a full description of the person, such as [[Marcin Jakubowski]]. This will facilitate referencing and connection between projects and developers. The potential contributions of a person should be transparent if they fill out their abilities in the [[Team Culturing]] Survey.

Please see '''[[how to get a wiki account]]''' for more details or if you are unable to log in.

== Grouping ==

* '''Categories''' can be used to organize a large number of pages, media, and even other categories. Read [[Using Categories]] for more information on proper categorization.
* '''[[#Creating Subpages|subpages]]''' can also be used to group pages. They organize information hierarchically. However, too many nesting will lead to a long name that is hard to remember.

== Creating New Pages ==

To start a new page or to edit an existing one, just type the desired page name in the [[#Searching|search box]] at the top left corner (the one '''above''' the ''OSE custom search engine'' box) and click on the button labeled '''Go'''. If a similar page already exists, you might want to edit that page instead of creating a new one. Otherwise, click on the message '''Create the page "''your page name''" on this wiki!''' (at the top of the search results) to create the new page.

Then you can start editing the page. Also, while editing a page, you can create links to new or existing pages with double brackets around their title, for example: <pre>[[My New Additions]]</pre>

== Creating Subpages ==

{{Tip|When to use subpages|
A subpage can be used to group pages belonging to some topic or main page
* to create user-specific pages in a given user's ''[http://meta.wikimedia.org/wiki/Help:Link#User_space user space]''.
* to create [[Translation#Page_Title_Convention|other language versions of an article]]
* to create '''archives of old discussions''' under a talk page
* to create '''scratchpad editing spaces''' under a user page
}}

{{Info|User Spaces|Pages on user spaces do not have to follow strict quality guidelines, as they '''are not official''' OSE content.
Other pages should reflect more closely the official OSE stance on a given issue.}}

If you want to create a [http://www.mediawiki.org/wiki/Help:Subpages subpage] named '''A subpage name''' under a given page (for instance, '''My Parent Page'''), all you have to do is to ''create a page'' whose title is '''My Parent Page/A subpage name''' ''(see [[#Creating_New_Pages|how to create a page]])''.

You can also link to subpages from the parent page using a [http://meta.wikimedia.org/wiki/Help:Link#Subpage_feature specific link format].

=== Examples ===
* [[User:Elifarley/pds]] - a subpage named '''pds''' in [[User: Elifarley| Elifarley]]'s user space

A page is a good candidate for deletion if:
* it is '''clearly and beyond a doubt''' spam or complete nonsense
* it's a redirect page whose title has nothing to do with the page it redirects to
** As an example, we had a page titled '''My resume''' containing someone's resume. All pages pointing to ''My resume'' were updated to point to the user's resume, and all pages that pointed to it were updated to reflect the new title.
** Another example: a page named '''How to cook using only sunlight''' that redirects to '''Arduino controller schematics''' doesn't make sense. Either redirect it to a page that deals with the subject of ''cooking using only sunlight'', or delete it.

=== How to Delete ===

{{Warn|Before Deleting a Page|
'''Never delete a page that is not clearly and beyond and doubt''' a spam page. '''A [[#Redirecting|redirect]] is often more appropriate'''.<br/>
You're urged to read [http://www.mediawiki.org/wiki/Help:Deleting_a_page Deleting a page] and [http://www.mediawiki.org/wiki/Help:Sysop_deleting_and_undeleting Sysop: deleting and undeleting] before you delete a page.
}}

Only Sysops can delete pages. If you're not a Sysop and you would like to mark a page as a candidate for deletion '''(see the [[#When_to_Delete|criteria for deletion above]])''', you should add the following text at the top of the page you would like to delete:
<nowiki>{{delete}}</nowiki>
This will include the [[Template: delete| delete]] template and will add that page to a list of [[:Category: candidates for speedy deletion| candidates for speedy deletion]].

And if a page is to be deleted, all pages pointing to it should be changed BEFORE the deletion occurs, to avoid broken links.

== Redirecting ==

You can redirect a page to another page by replacing the contents of the original page with a '''#REDIRECT''', like this:
<pre>
#REDIRECT [[My destination article]]
</pre>

You can redirect a page to an [http://www.mediawiki.org/wiki/Help:Links#Interwiki_links interwiki link] too:
<pre>
#REDIRECT [[Appropedia: Justa stove]]
</pre>

[[Using Categories|Adding a category]] may help others find the page, since it'll be listed on the corresponding category page:

<pre>
#REDIRECT [[Appropedia: Justa stove]]
[[Category: Cooking]]
</pre>

{{Tip|Too many redirect pages?|If you're afraid that the wiki will get cluttered with redirected pages, fear not. You can see this as a feature (a good one), not a bug, since anytime someone tries to add a page with title X (X being one of those redirected pages), they would be redirected to the appropriately-named page, instead of being given the chance to create a page with different title but similar content.}}

== Editing Pages ==

{{Tip|Tips|
* '''Before editing''' a page, click the '''discussion''' tab at the top to check what others are saying about that page
** You can add your own considerations or questions there too
* '''To edit existing pages''', just click the '''edit''' tab
* '''Before saving''' your changes, click the '''Show preview''' button located just below the editing window to make sure everything is as expected
* '''To save''' your work, click the '''Save page''' button
}}

While in edit mode, there are some buttons at the top of the editing window to help with formatting text, creating links, inserting objects, etc.

=== Sections ===

'''[http://meta.wikimedia.org/wiki/Help:Wikitext_examples#Section_headings Section headings]''' are created by creating their headings, as below:
<pre>
== First Section ==
=== First sub-section ===
==== First sub-sub-section ====
== Second Section ==
</pre>

{{Tip|Top-Level Sections|Top-level sections should start with '''2 equal signs at each side''', as in '''<pre>==My Top-Level Section Example==</pre>'''

Sections with only one equals sign per side causes a title the size of the page name. On Wikimedia wikis they are used only sparingly and in prescribed circumstances.
}}

=== Inserting Tables ===

You can copy and paste your data from your spreadsheet to http://area23.brightbyte.de/csv2wp.php and it will convert it to a cut and pasteable mediawiki table.

=== Inserting Templates ===

You can insert a [http://meta.wikimedia.org/wiki/Help:Template template] using this code:
<nowiki>{{My Template}}</nowiki>

To '''create or edit a template''' named ''My Template'', '''simply create a page''' named ''[[Template: My Template]]'' (see [[#Creating_New_Pages|how to create a page]]).

== Text Markup ==

=== Text color ===

Put in the name of the color in this markup:
<pre><span style="color: green">Some text</span></pre>
The example above generates this:

<span style="color: green">Some text</span>

=== Strikethrough ===

<s>Strikethrough</s>

=== Inserting Images ===

==== Uploaded Images ====

To insert an image, anywhere in the body of a page, type:
<pre>
[[Image:filename.jpg]]
</pre>
Then click ''Save page''. After the page is saved, you'll be allowed to click on that filename, and the wiki will prompt you for an image file to upload.

==== External Images ====

You can simply paste links to images from any of the sites defined on [[MediaWiki: External image whitelist]].
See also: [http://www.mediawiki.org/wiki/Manual:$wgEnableImageWhitelist $wgEnableImageWhitelist]

Example: '''<nowiki>http://openfarmtech.org/temp-gvcs-icons/3d-printer.png</nowiki>''' gives this image:

http://openfarmtech.org/temp-gvcs-icons/3d-printer.png

==== Inserting Image Galleries ====

Use the ''gallery'' tag. Example code:
<pre>
<gallery>
Image:fefrepstrap1.jpg
Image:fefrepstrap2.jpg
Image:fefrepstrap3.jpg
Image:fefrepstrap4.jpg
Image:fefrepstrap5.jpg
</gallery>
</pre>

Produces this:

<gallery>
Image:fefrepstrap1.jpg
Image:fefrepstrap2.jpg
Image:fefrepstrap3.jpg
Image:fefrepstrap4.jpg
Image:fefrepstrap5.jpg
</gallery>

=== Linking files ===

If you want to link uploaded files in the Wiki, then you use this code: '''<nowiki>[[media: file name]]</nowiki>'''<br/>
See an example [[Press_Procedure|here]].

=== Inserting Movies ===

To insert movies, see this example:

<pre>
<html>
<object width="526" height="374"><param name="movie" value="http://video.ted.com/assets/player/swf/EmbedPlayer.swf"></param><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always"/><param name="wmode" value="transparent"></param><param name="bgColor" value="#ffffff"></param><param name="flashvars" value="vu=http://video.ted.com/talk/stream/2011U/Blank/MarcinJakubowski_2011U-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/MarcinJakubowski-2011U.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1122&lang=eng&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=marcin_jakubowski;year=2011;theme=design_like_you_give_a_damn;theme=new_on_ted_com;theme=the_rise_of_collaboration;theme=tales_of_invention;theme=talks_from_ted_fellows;event=TED2011;tag=Culture;tag=Technology;tag=open-source;tag=ted+fellows;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;" /><embed src="http://video.ted.com/assets/player/swf/EmbedPlayer.swf" pluginspace="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" wmode="transparent" bgColor="#ffffff" width="526" height="374" allowFullScreen="true" allowScriptAccess="always" flashvars="vu=http://video.ted.com/talk/stream/2011U/Blank/MarcinJakubowski_2011U-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/MarcinJakubowski-2011U.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1122&lang=eng&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=marcin_jakubowski;year=2011;theme=design_like_you_give_a_damn;theme=new_on_ted_com;theme=the_rise_of_collaboration;theme=tales_of_invention;theme=talks_from_ted_fellows;event=TED2011;tag=Culture;tag=Technology;tag=open-source;tag=ted+fellows;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;"></embed></object>
</html>
</pre>

The code above generates this:

<html>
<object width="526" height="374"><param name="movie" value="http://video.ted.com/assets/player/swf/EmbedPlayer.swf"></param><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always"/><param name="wmode" value="transparent"></param><param name="bgColor" value="#ffffff"></param><param name="flashvars" value="vu=http://video.ted.com/talk/stream/2011U/Blank/MarcinJakubowski_2011U-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/MarcinJakubowski-2011U.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1122&lang=eng&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=marcin_jakubowski;year=2011;theme=design_like_you_give_a_damn;theme=new_on_ted_com;theme=the_rise_of_collaboration;theme=tales_of_invention;theme=talks_from_ted_fellows;event=TED2011;tag=Culture;tag=Technology;tag=open-source;tag=ted+fellows;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;" /><embed src="http://video.ted.com/assets/player/swf/EmbedPlayer.swf" pluginspace="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" wmode="transparent" bgColor="#ffffff" width="526" height="374" allowFullScreen="true" allowScriptAccess="always" flashvars="vu=http://video.ted.com/talk/stream/2011U/Blank/MarcinJakubowski_2011U-320k.mp4&su=http://images.ted.com/images/ted/tedindex/embed-posters/MarcinJakubowski-2011U.embed_thumbnail.jpg&vw=512&vh=288&ap=0&ti=1122&lang=eng&introDuration=15330&adDuration=4000&postAdDuration=830&adKeys=talk=marcin_jakubowski;year=2011;theme=design_like_you_give_a_damn;theme=new_on_ted_com;theme=the_rise_of_collaboration;theme=tales_of_invention;theme=talks_from_ted_fellows;event=TED2011;tag=Culture;tag=Technology;tag=open-source;tag=ted+fellows;&preAdTag=tconf.ted/embed;tile=1;sz=512x288;"></embed></object>
</html>

For any video, insert the <nowiki><html> and </html></nowiki> tags, and put in the html code that you get from YouTube or some other video format.

=== Embedding from Blip.tv ===

Here is a sample embed settings screen from blip.tv. Note that you do 'share', 'legacy player', then click 'go.' Then, make sure you select 'in-line player', flv for flash video - and then click 'update embed code above'. Then, copy the code into the blog, and in the blog, make sure you are in HTML, not visual, mode.

[[Image:blipembed.jpg]]

=== Subtitling Videos ===

Here's how to activate Universal Subtitles for your videos:

1- Go to http://universalsubtitles.org/ and click on "Subtitle a video"
2- Paste the URL of the video you want to have subtitled. The URL can point to a file in Ogg, WebM or FLV format, or it can point to a video hosted on YouTube or Blip.TV (Vimeo support will be available soon). Examples of URL:

WebM file: http://content.bitsontherun.com/videos/m3P14laP-283112.webm
YouTube video: http://www.youtube.com/watch?v=shqrdCBTD70
Blip.TV video: http://blip.tv/file/3841170/

3- A black page with a central video and a close button (a red tab on the top right corner) will appear. This is the initial step where users can start typing the subtitles for the video. Since you probably don't want to create the subtitle text right away, but instead want the embed code to paste on your blog, you can just click on the close button.

4- In the next screen, the embed code can be found inside the text box below "Embed this video in your site". Just click on the 'Copy to clipboard' icon next to it. The embed code will look like this:

<pre>
<script type="text/javascript" src="http://s3.www.universalsubtitles.org/embed.js">

(

{"video_url": "http://www.youtube.com/watch?v=shqrdCBTD70"}

)

</script>
</pre>

This embed widget is in alpha stage, so it may have some bugs. I have tested it with youtube videos and it worked quite well. With Blip.TV, the video wouldn't play though.

It'll be really great when it's working correctly with Vimeo and Blip.TV

=== Inserting Source Code ===

Always wrap source code in 'pre' tags. This ensures proper formatting, and means that someone can copy code without having to 'edit' the page first.

An example looks like this (you can view the markup in Edit mode):

<pre>
int mainup = 5; // Define pins by plugin of hydraulics
int maindown = 6;
int secin = 10;
int secout = 11;
// Define pins 5, 6, 10, and 11 according to their hydraulic
// function on the CEB press - moving main cylinder up and down,
// and moving secondary cylinder in and out. 'In' is defined as
// the direction of brick ejection motion out of the machine.
</pre>

=== Adding Categories ===

If you want to add a specific category to your page, please check the already existing [[Template:List_of_categories|list of categories]].
