Take Team Culturing Survey and do the Recruiting Survey.
Mon Apr 29, 2013
Tasks - (1) Download Sketchup - follow the tutorial and build an actual cube - first See Sketchup Tutorial Box at OSHW-OSE-CNC_Torch_Table-v2. Please post your results at: Sketchup Cube Test. (2) Create a sample Control Panel for projects - Audrey Control Panel Sandbox. Put in a YouTube of your choice into the first window, while the changing the text and link to the corresponding value. Put in a Google spreadsheet of your choice into window 7. (3) Create a Google Drawing showing all the types of people that we are inviting to the Development Sprint. See the OSE Jam which talks about the people required. Put up your Graphic at OSE Jam Team Design. (4) Document how to build a Google Form at How to Create a Google Survey. Design a Google Form for Team Recruiting Form - specifically for 4th of July Campaign of the Sweet 6 - or 6 prototypes designed and built by July. Planning for an agile Sprint - which a Hackathon where everyone works together on a common goal. Put up your resulting Google Form up at the Control Panel for the Microtrac page - OSHW-OSE-Microtractor-v2. Include Documenters as one of the particular groups involved to fill in OSE OManual Documentation realtime. Put up your sample survey design at Team Recruiting Survey Design. See also the LifeTrac Construction Set Script.
Task Update
- Completed Sketchup download, tutorials, and test. Posted notes, lessons learned and product at Sketchup Cube Test.
- Completed draft documentation on how to build a Google Form at How to Create a Google Survey. Will finalize once survey is complete.
- Began creation of Google Form for a Team Recruiting Survey. Reviewed past surveys, drafted questions. Among other things, requesting information about involvement in social media (Facebook, LinkedIn, Twitter).
- Began reviewing requirements for Jam Team--need more guidance: purpose, what type of tool is this (pictorial, informational, etc); drafted personnel requirements/expertise overview--product designers, mechanical engineers, documenters, CAD designer, animator, digital/flexible fabricator, other?
Modernized Steam Engine Project Plan
Notes from 26 Mar 2013
- Finalized and submitted plan, updating research links, sources, potential contacts, etc. Submitted Configuration Management sample. File:Modernsteam.docx
Notes from 25 Mar 2013
- Updated project plan notional schedule and underlying processes for project development
- Revised plan--less technical, refocused on processes
Notes from 24 Mar 2013
- Continued COTS research with Cyclone Power Technologies http://www.cyclonepower.com/technical_information.html. Excellent source for engineering solutions, though patented technology, not in FRP, no cost data. Uses deionized water vs lubricant (will this wear parts & effect reliability?) Seems to solve condensation issues; utilizes multiple heat exchangers. Additional resources:
- Researched steam technology in auto industry: BMW, Saab & Honda
- Paper utilizing technology developed (and shelved by Saab) in the '70s from Ranotar http://www.steampower.com/publications/Ranotor2004.pdf and http://www.saabhistory.com/2008/04/04/the-nine-cylinder-saab-steam-engine/
- BMW Concept Car: https://www.press.bmwgroup.com/pressclub/p/pcgl/pressDetail.html?title=looking-for-the-next-gram&outputChannelId=6&id=T0119738EN&left_menu_item=node__2367 and http://www.motortrend.com/features/editorial/112_0606_technologue_hybrid_qa/viewall.html
- Honda utilizing steam in Honda Stream hybrid http://www.ecogeek.org/automobiles/1380
- Need to continue researching Cyclone's solutions (i.e Waste Heat Engine project).
Notes from 23 Mar 2013
- Analysis of alternatives:
- Researched bump valve reliability, researching alternative solutions
- Need to discuss condensation issue and air compression issue on the return stroke (sending note to M. Norton)
- Power vs pressure: The higher the pressure, the smaller and lighter the engine (weight to power ration)...optimum pressure for SWAP requirements?? Include risk analysis (higher pressure/heat = higher safety risks), probable effect on cost. Continue researching.
- Reviewing Green Steam Engine products; available at http://greensteamengine.com/products.htm The 2 cylinder product provides 10 hp at 125 psi, 1500 rpms; drawings/instructions/hard to find parts available for purchase. Other products available via COTS: http://greensteamengine.com/ ; will make contact with POC for more info re: 3,4, and 6 cyl eng.
Notes from 22 Mar 2013
- On travel, no work performed
Notes from 21 Mar 2013
- Updated project plan general requirements/specs and better defined FMECA process
- Continued researching alternatives to issues with OSE Arrow Head Engine
- Explored differences in V-shaped layout/feasibility; assessing
Notes from 20 Mar 2013
- Contacted Mark Norton; directed to https://sites.google.com/site/phase3project/projects/steam-engine/engine-designs/ose-arrow-head-engine
- Began researching the following issues with the OSE Arrow Head Engine:
- Water might condense in the cylinder chamber resulting in a blow-out condition
- Power output will be low unless operated at high speed and high steam pressures
- Bump valves are subject to wear and breakage
- Air is compressed on the return stroke, losing valuable work
- Horizontal layout leads to excessive wear on parts (piston rings, etc).
