Input
7:30 am
- Woke up, slept ok, bit dehydrated.
- Found there was no hot water. Scott going to check the shower / propane tank.
- Great hangout with Mike and Scott over coffee this morning
- Scott cooked an amazing breakfast.
- Read Chris Reinhart Log entry for 21st November 2013, Chris_Reinhart_Log#Longwinded_Debrief_on_FeF_Procedures_after_November_Visit:_On-Boarding_Ideas.2C_Meeting_Titles.2C_and_the_Dinner_Bell
9am meeting
- Marcin asked DPVs: would you update facebook if you were invited. There was a general aye in response.
- Marcin request for me to update my log
Feedback on meeting
- beginning 15mins of morning meeting was productive: storytelling and task assignment.
- Very little Interaction with remote participants, tech issues, mic problems, echo/feedback.
- Meeting became less productive for Rob, Katie, Audrey and Sam when the discussion turned to prototyping the workshop stove which is out of scope for all of us except Mike, Scott and Marcin (signal/noise ratio decreased!).
- There were no introductions made for Mike, and little to no onobarding took place, morning plan: he will be shadowing Marcin and Scott in the workshop to install the stove and then mabe looking at roads / surfacing.
- Reminder: essential to upoload ~9:10am Friday 22nd November 2013 videos / stories to youtube and link from Logs! Source: Stories from this morning are on Marcin's Tablet and Sam's G3.
- Key Takeaways:
- story telling good
- task assignment good
- need to stay focused on torch table, process efficiency and general team wellbeing
- bail on future meetings at the point when the signal to noise ratio goes down w.r.t. CnC Torch Table (reason: not in scope) i.e. a prototyping meeting style on a module / project I am not working on, this will prevent frustration and save about 50mins of peak concentration/working time / day.
10am to 1pm: Morning work session
1pm to 2pm
- Lunch!
2pm to 5pm: Afternoon work session
- Find Mic, Camera and Speakers for Mac Mini
- Read: Audrey’s Workshop Organization & OSHA/Safety Notes
5pm: Free time
- 3d printer audit -> purchase list for repairs
- Check hal9000 after ubuntu 12.04 upgrade
- Create Mashup between OSE Wishlist and Freecycle Missouri
Output
- Printed out Chris_Reinhart_Log#Longwinded_Debrief_on_FeF_Procedures_after_November_Visit:_On-Boarding_Ideas.2C_Meeting_Titles.2C_and_the_Dinner_Bell to the notice board.
- Personally Adopted Chris' Proposed Schedule to maximise personal productivity, thanks Chris!
- Updated log from today, pending backlog to update log entries from 19th November to 21st November.
- Created a backlog: upload as many stories as possible and link from personal logs. (
- Started Next task from Scrumy board: https://scrumy.com/samthetechie "Sketchup of Y Axis Drive"

- Discussed FEA / Analysis with User:Marcin
- Useful Resources on FEA (Finite Element Analysis):

- Frame3DD Sketchup Interface - Discussion about the plugin on sketchucation.com/forums
Note in the discussion that the modelling is done with 1" x 1" by 2mm thick SHS (Square Hollow Section). It is quite likely that the modelling parameters can be altered to allow analysis of 4" x 4" by 1/2" thick SHS:

- Evolving articulated pivot design based on CAD / images found at Error creating thumbnail: File missing, GrabCAD_Backhoe_Redesign_for_Fabrication,Error creating thumbnail: File missing, GrabCAD:lifetrac-backhoe, GrabCAD lifetrac-backhoe winner and mainly Backhoe Concept video from User:Marcin
- Wrote a quick guide for Sketchup_on_Linux
- Note: quick way to grab all the .skp files that have been uploaded onto the wiki.
Go to Special:ListFiles&limit=500&ilsearch=.skp and then using the down them all plugin for firefox and 'fast filtering' with /(.skp)$/
- Some notes on edge alignment in sketchup that I found useful today:
"A second method for ensuring your edges are aligned to axes is to temporarily change the colors of your edges to reflect their alignment to one of the axis. To change edge colors to reflect axes colors."
- Reviewing recent wiki changes and latest pages relating to the Backhoe:
- OSE-OSHW-Dev-Backhoe
- Brian_Log
- Marcin_Log
- Backhoe_Boom_in_Sketchup was last updated on 06:19, 18 May 2013 by User:Marcin so it is out of date.
- Backhoe Prior Art - Marcin
- Backhoe_Stick_and_Boom_Concept_Specification#Response - points 1-3 of this response were addressed by editing the components, points 4-6 can be addressed by creating models sub-assemblies and assemblies today.
- Backhoe_Development_Brief - looks like a todo list for today
- Backhoe_Pivot_Module_Academy - new page, no content yet.

Input
- File:Stock Pivot Plate.skp
- Feedback from User:Marcin about File:Backhoe.skp
To generate a CAM file for 3D printing, one must consider the 3" tubing and print out a 3" hole, not a 4.875" hole and ensure hole is correct for 3d printed files.
- New pivot plate File:Stock Pivot Plate 3 inch hole.skp should address feedback from User:Marcin about the 3" pivot hole.
