* Hanging out in Hammerspace
* Advice on woodstove:
Specs are available via NFPA 211. Stove clearances, flue pipe design and height, insulating boards underneath and against the wall. We should, ideally put a spacer in with
* http://woodheatstoves.com/free/NFPA211_old.pdf page 28 (of 59) highlights required clearance distance to combustible materials.
* http://woodheatstoves.com/free/NFPA211_old.pdf page 15 (of 59) read general requirements,
* 10-2 rule which means 10 foot to top of the flue and 2 feet above the top of the roof
* Also check the specifications for gas burning appliances.
* Note: http://www.ehow.com/list_7179572_dangers-burning-osage-wood-fireplace_.html burns very hot! Beware! Must mix with other woods.

**Theory**
* Simple 3 stage dynamic building model theory: http://openenergymonitor.org/emon/node/2999
* Radiator model (documentation in progress): http://openenergymonitor.org/emon/node/3011
* Heatpump model (documentation in progress): http://openenergymonitor.org/emon/node/3021

**Software**
* Emoncms Module: OpenBEM implements 3 stage dynamic model:

===[[Equipment/Lulzbot_a0_101|Lulzbot]] Tuning===
* Every time a print started the z-axis motors were trying to turn faster than they actually could so following http://forum.lulzbot.com/viewtopic.php?f=8&t=85 I set a limiter using m-code: M203
* Setting max Z speed in Slic3r? is it possible?
You can set the firmware max speed with an M code:
X axis: 11,500 mm/min (192 mm/sec)
Y axis: 12,500 mm/min (208 mm/sec)
Z axis: 250 mm/min (4 mm/sec)
* Then just send the following command to the firmware:
M203 X192 Y208 Z4
...and now the machine will never move faster than those settings, even if the g-code or printer host software commands it to. The same will probably apply to the [[Equipment/Taz|TAZ]] and the [[Equipment/HydraFabber|HydraFabber]] printers.

* Took the day off to hang out with Mike and Scott!
* Took out the recycling (photos + guide to follow).
* 3D Printed some widgets for the Hablab: 2 x classic reprap [http://reprap.org/wiki/File:Coat-hook.stl coathooks] (need to print 2 more!), a [http://www.thingiverse.com/thing:40079 mason jar handle] (need to print 5 more) and a toothbrush head cover for Mike.

==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'''
* Getting distracted by having to answer the telephone and the cat going nuts / running around.

'''1pm to 2pm'''
* Lunch!

'''2pm to 5pm: Afternoon work session'''
* Find Mic, Camera and Speakers for Mac Mini
* Read: [https://docs.google.com/document/d/1vpS3AgriebZSV1K78PjpMTVF3PnoxU8WqjayeRST-Iw/edit 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 [https://docs.google.com/document/d/1byxdJtbUaeZI2CFTe2zsq-3v-s9b6ebSZ6nuAA4Ii4A/edit# OSE Wishlist] and [http://www.freecycle.org/group/US/Missouri Freecycle Missouri]

* 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"
* Went on a scavenger hunt in the OSE workshop for electronics parts, brough box of stuff back to hablad in order to make a little nest / electronics desk/woskbench.

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:

*Some notes on [https://support.google.com/sketchup/bin/answer.py?hl=en&answer=114011 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."

===[[Equipment/Lulzbot_a0_101|Lulzbot]] Tuning===
* Every time a print started the z-axis motors were trying to turn faster than they actually could so following http://forum.lulzbot.com/viewtopic.php?f=8&t=85 I set a limiter using m-code: M203
* Setting max Z speed in Slic3r? is it possible?
You can set the firmware max speed with an M code:
X axis: 11,500 mm/min (192 mm/sec)
Y axis: 12,500 mm/min (208 mm/sec)
Z axis: 250 mm/min (4 mm/sec)
* Then just send the following command to the firmware:
M203 X192 Y208 Z4
...and now the machine will never move faster than those settings, even if the g-code or printer host software commands it to. The same will probably apply to the [[Equipment/Taz|TAZ]] and the [[Equipment/HydraFabber|HydraFabber]] printers.

==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'''
* Getting distracted by having to answer the telephone and the cat going nuts / running around.

'''1pm to 2pm'''
* Lunch!

*Some notes on [https://support.google.com/sketchup/bin/answer.py?hl=en&answer=114011 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:
