Meeting Notes

Wed, 9 Oct 2013

Agenda:

1. Backhoe Status: 1) Pivot - Sketchup, 2) Stick - motion analysis, 3) Quick Attach - Concept Drawing
2. Documentation Status

Backhoe - continue design & ROM analysis

Wrap Up

• Backhoe Status:
  • Pivot: Sketchup design is 95% done; BOM is next, then assembly work instructions, need to do hydraulics -- hydraulics should be 16" pin-to-pin
  • Quick attach: INW & interface piece
  • Found a design flaw -- there isn't enough space for the pivot cylinders; Dan is developing a work around
• Documentation:
  • Emmett needs to re-do one animation for the deconstruction animation on the LifeTrac 6; its going to take a long time to export the clips though--Emmett is researching to see if there is a way to export a large batch vs individuals
  • Emmett's next step: edit & import photos to Trovebox via jpeg; needs resolution standard (must be at least 400x400)
  • Rob recorded the Prezi for The Feast
  • LifeTrac 6 Documentation: ready for replication -- wheels & cab; can ID what works and what doesn't
• Logistics:
  • Prototyping material for scaled modeling; Audrey is going to Hammerspace on Friday to cut more materials
  • 10" Bolts from MoKan - won't be here until Wed / Thurs next week; workaround: use threaded rods and cut to size
• Other: Cody had a fundraising idea for future Microhouse construction; Katie took notes and will develop

Tomorrow's Plan

• Microhouse: Handyman Donnie bailed on us, we are going to pursue Labormax and operate within their confines

Tues, 8 Oct 2013

Agenda:

1. Backhoe Status: pivot
2. Microhouse Update: One DPV plus a temp worker (trying to get Mark), will work on the MH roof on Thurs
3. Documentation Status
4. Logistics: 1) Cylinder order, 2) Other parts that may be 'long lead' orders? (i.e. 10" bolts?), 3) Add'l Rapid Prototyping materials

Backhoe Status

• Dan suggested using trunions cylinders may work; Marcin brought up issues with using these cylinders wrt sourcing: price & availability; may be able to modify existing cylinders through a weld which will negate adding a special part--may explore welding but there is a risk with welding as well.
  • Way forward: Pursue solution that is a single control that gives us 160-170 degrees rotation; draw in LibreCAD--perform analysis, build a scaled model--perform analysis; draw in SketchUp; contact Design Sprinter that offered to do stress analysis
• Stick: need to do motion analysis
• Quick attach: develop a concept drawing for the Quick Attach, need to design the "female" part that is mounted to the backhoe

Microhouse

• Cody will lead roofing on Thurs

Documentation Status

• Emmett will try and do the deconstruction animation today; he has been grouping appropriate parts within the cab
• Rob will go through the video of the cab to break down into a script to assist Emmett's efforts; Rob is also working on a video of the MH

Logistics

• Cylinder order: not yet
• Long Lead parts: 10" bolts from MoKan x 100, 1" washers x 100
• Prototyping materials: screws, 80 pages of what we have; what is the size (working area) of their laser cutter?

• Additional prototyping materials: screws,

Actions

1. Backhoe: Dan is working Trig analysis; Marcin is doing LibreCAD drawing; Cody is
2. Modeling: Cody is grinding down screws for the 3D modeling
3. Inventory: Cody is going to perform inventory
4. Audrey will call labor max to reserve Mark or other for roofing
5. Audrey will source laser cutting in KC - get info on system

Wrap Up

1. Backhoe pivot status: Geomoetry C/W, starting Sketchup; Maercin is working paper models exploring other ideas, Dan completed 2D LibreCAD pivot drawing; Will need to reassess the part that attaches to the quick connect for integration issues
2. Modeling:C/W, screws ground down
3. Inventory: Cody inventoried all of the plates; we do not need to buy cylinders; will likely need more steel cut -- need to determine last due date for BOM
4. Roofer: Donnie, a local handyman, is coming out on Thurs and will work with Cody.
5. Laser Cutter source: Audrey is getting Hammerspace membership, calling for more details
6. Documentation: Rob is still digitizing footage from MH, Roofing footage is done; Emmett is struggling -- difficult to control Sketchup animation--taking numerous attempts to gain a smooth motion.

Mon, 7 Oct 2013

Agenda: 1) Backhoe Status, 2) Ironworker Status, 3) Microhouse Status, 4) Documentation

Backhoe

• Goal: Decide design vector for pivot by COB today via Tech Tree of Choices; begin 3D modeling of Design in Sketchup
• Backhoe Pivot:
  • Using Laser cutter pieces to build a small scale pivot (blog input & newsletter topic)
  • Dan & Cody created a viable option that will give us 160 degrees of motion (goal is 180 degress -- 90 degrees on each side)
  • Industry standard includes additional control mechanisms on the side of the pivot to allow for additional ROM
  • Need to complete a Tech Tree of Choices to determine path forward
  • Need to use LibreCAD to do a quick 2D analysis of ROM
  • Does 180 degree ROM apply to industry standard Backhoes that do not use a gearbox? What ROM do they get?
  • Discussion on custom work: may integrate minor custom work into design to allow for greater ROM; need to include these as options for analysis of complexity
• We have 8" and 10" cylinders; but they may not have the correct diameter cylinders; may need between 8-12" -- let's order what we need today

• Backhoe Bucket:
  • Need to determine proper pin mounting

Ironworkwer

• Tabled --Need to discuss with Marcin and roll into schedule

Microhouse

• Microhouse: Need to finish roof...work this into Ironworker / Backhoe schedule; get additional manpower to assist with this from temp agency

Documentation

• Trovebox - DPVs will need to use Rob's login to upload from smartphones
  • Need to create a DPV General User account so staff accounts are not compromised
  • Need to provide feedback to Trovebox for improvement; we are part of a beta-test...need to include youtube, vimeo, Dozuki access, LibreCAD for simple 2D design -- need instructionals
• New documentation method -- 1) Explode the diagram; 2) Play it in reverse to create a dis-assembly to assembly using animation (i.e. the Phoenix Method w/ animation). Issue: capturing the animation on screen; need to work this out (Rob will work this and get back to us). If it works, they will try the cab.

Other

• Emmett is likely leaving Saturday or Sunday
• Time off -- If DPVs need some downtime, speak up!
• Workshop cleanup
• Media focus this week: Rapid prototyping capability using laser cut pieces
• Meetings: 9am Daily Product Development Meeting; 4:30pm Wrap-up

Actions

1. Work on animation and sequencing for documentation purposes and work out our methodology -- Rob & Emmett
2. Tech tree of choices for pivot -- Cody
3. Build pivot in LibreCAD for 2D ROM analysis -- Dan
4. Order cylinders -- Marcin will order if needed
5. Shop cleanup -- ALL prior to workshop work today
6. Add info to DPV O&M Board: youtube, vimeo, LibreCAD, & Dozuki access -- Audrey (with Rob's help)
7. Create a DPV General user account for Trovebox? -- Rob
8. Integrate Tech Tree of Choices instructions / protocol into Dev Board -- Marcin

End of Day Wrap Up Agenda: 1) Status on actions #1-3, 2) Decision: #4, 3) Other issues, 4) Next steps

Status of Actions

• Emmett needs the LFT 6 step instructions (Audrey to send from Gary's Log)
• We will need to take each frame and string them together; need to create procedures process is refined
• Used new capture program iShowU HD
• Tech Tree of Choices: Backhoe Pivot -- Tech Tree of Choices
  • Used Coggle to develop Tech Tree -- need to work out Coggle integration issues with our wiki
• LibreCAD update: just used pen & paper and cardboard vs LibreCAD--we have two ideas: 1) two controls/valves for increased range of motion, 2) Single valve with less range of motion. Next step is to use prototyping tools to build each and test the ROM.
• Shop clean up -- some worked was done.
• Rob will contact
