Started github repository for MicroTrac here: https://github.com/skikro/microtrac 
Populated Github with files I could find, working on putting more in. This should help the microtrac project collect the cad files better. The wiki is still the best page for documentation, but the github repo will be a great way to keep track of all the assemblies and CAD files without cluttering up the page. 
Also made a ton of edits to [[Tractor Construction Set 2018]] 

=Tues Apr 10, 2018=
Start wiki page for 2018 tractor set

Updates to Microtrac 
Updates to D3D, potential replication? 

=Tues Nov 7, 2017=
This week is going to be working through MicroTrac documentation [http://opensourceecology.org/wiki/MicroTrac_v17.10 here] 
The documentation will really help when doing a ceiling analysis 

Potential tractor projects are:
*tensioner mechanism 
*loader arm reconfiguration 
*idler shaft mounting? 

=Fri Nov 3, 2017=
Planning out next parts to model up 
Found [https://www.coursera.org/learn/fluid-power this course on fluid power] on Coursera. Seems cool! 
If it becomes useful in the future, Open source equivalents to Matlab/Simulink = Octave/Sci Cosim 
Came up with some cool ways to cut out the loader arms by hand by taking measurements from a 2D sketch, which part sketch can be found here 

=Wed Nov 1, 2017=
Google just released [https://research.google.com/colaboratory/unregistered.html this google-doc like environment for data science], basically a big jupyter notebook that has prebuilt dependencies. It would be super cool to have something like this for FreeCAD and documentation

Day 5 of tractor build. We got the tractor running and Marcin drove it around. It has A LOT of power 
The tensioning mechanism and motor mount configuration definitely has the most work that needs to be done. 
Need to do some quick research into finding a good crash course on hydraulics 

=Sun Oct 29, 2017=
Day 4 of tractor workshop 
Spent the morning helping figure out the situation with the sprocket and motor mount attaching to the tensioner. This was a pretty major issue that prvented us from getting the tractor running today. I really do think we'll get it running early tomorrow. 
There could be a better way to mount the shaft with a single collar bolted to the bottom of the frame. Eliminating the shaft clamp and motor mount plate in favor of a single
Spent a good chunk of the afternoon figuring out the cuts for the second piece of the loader arms. Check out the doc [https://docs.google.com/document/d/1FG4wOzv64sImBDVfdeiitX74Q6akCFXsgZ-b3uA86UE here] . I'm actually really impressed we were able to build them up and tack them with just a torch, grinder and welder. It's been a really powerful experience to recognize how little is necessary to actually build these machines and get them going. 
I've been really impressed at what can happen when you get so many people together to work on a project like this. 
We worked until about midnight-thirty to get the loader arms set up, tighten and check that the tensioning mechanism works. 
I was also feel like we could really drop the size of the power cube more by reconfiguring the cooler, engine configuration and the motor coupling. 

=Sat Oct 28, 2017=
Day 3 of tractor workshop 
Spent a good portion of the day learning FreeCAD drawing dimensioning workbench to get some dimensions for the loader arms 
After the frame was welded up, I welded on the motor mount plate and we were able to get the power cube running 
Cut out some 1 bolt shaft clamps in the evening 
I think it has been really valuable to have some solid CAD to be able to pull from and tweak and draw up to make sure things fit together well 

=Fri Oct 27, 2017=
Day 2 tractor workshop 
Spent the morning doing some FreeCAD dimensioning and drawing for Power cube (future power cube cut lists like [https://davehakkens.nl/community/forums/topic/shredder-dxf-laserfiles/ this] would be great) 
We got the flat parts of the frame all cut out and welded up for the power cube 
Welds weren't perfect, and had to be majorly ground down. 
Another 10 hrs :)

Some primitive 2D sketch work on the vibratory plow, just for conceptual design, done in [https://docs.google.com/presentation/d/1FzlT3ZO4UANPsI6deq-4haAOYmi3u-XF07WfMrk1bKg/edit#slide=id.g27cb7bfd62_0_34 This Doc] 

Wow, vibratory plows are badass.... links: [https://www.youtube.com/watch?v=4Vb7-ZEW5vE here] and [https://www.youtube.com/watch?v=5LHObecYJwU here] 
They call it a "pipe puller" on the Toro Dingo. I think this is probably closest to what we want: [https://www.youtube.com/watch?v=u6OccLSLVOI here] and [https://www.toro.com/en/professional-contractor/compact-utility-attachments/dingo-vibratory-plow-22911 Toro Dingo Vibratory Plow] 
 
Spent some time working on some FreeCAD stuff with Lex (GT2 Pulley) 
I'm thinking it would be nice to have a CAD work "best practices" page put together if it doesn't already exist, trying starting with something like this: [http://homepages.cae.wisc.edu/~me231/online_notes/cad/modeling%20practices.pdf Best CAD Practices] 
 
Also, planning to head out to Factor e-farm for the tractor build at the end of October 
 
Implement talk from Marcin: 
I'd like to add one implement request before mower and tiller. It turns out that we need to trench 800 feet of power line to the seed eco-home for backup as we test the off-grid PV system at the Seed Eco-Home. Can you do a vibratory trencher as the first implement? It needs to go down only 12". Now you have the female mount, you can use that on it. Because microtrac is 41" wide, we also want to have a QA female that is 41" wide. Both would work if we make our male part a little more narrow. The pin locations are the limiting factor - but we have flexibility there as there are 2 pin locations on each side. 
 
See vibratory plot for insderting cable - https://www.ditchwitch.com/trenchers/vibratory-plows/410sx - on the back of thiis ditch witch. It is just a motor with a non-balanced weight on the rotor. We can use Abe's 5 cu in motor - http://opensourceecology.org/wiki/File:PTO_Hydraulic_Motor.fcstd

=Sun Oct 8, 2017=
DFM on the bobcat standard quick attach 
[https://docs.google.com/presentation/d/15g_Bm7r5jm8YzJb0kfjyAI4Now42G09fgGZuqId1CnE/edit#slide=id.g27bf2a97b9_0_2 Pictures and Links] about quick attach plates 
Redrew mounting plate with sheet metal approach: [[File:Bobcat-QA-female.FCStd]] 
The sheet metal add-on worked great (you can find it [https://www.freecadweb.org/wiki/Sandbox:Sheet_Metal here] ). My only qualm is the the bend feature doesn't have options for things like material added on the outside or inside or distance offsets. The radius also adds length to the total flange, which is unfortunate. Maybe we could get some programmers on that? 

=Sat Oct 7, 2017=
Some work for implements on the tractor: A 2-pto motor brush hog. Rotor direct coupled to motors. Use Abe's new motors, 5 cu in. The cutter is a cross, 8" wide, with 8" of chain welded to tips. So each cutter has a 24" overall diameter. Thus we get 48" of cut from an implement that 
A coumter-rotating time tiller driven by two high torque motors, same profile of motors as the 5 cu in. Motors ride on top, and are linked to the shafts via 100 chain [http://www.rollerchain4less.com/100-1R-X-10FT-Standard-Roller-Chain_p_830.html?gclid=EAIaIQobChMI1-23yfnZ1gIVkbrACh0xeQNdEAQYAiABEgI0qPD_BwEBut here], since that is so expensive (including sprockets), please just use our existing 8 tooth sprocket and chain links without track pads as in our tracks. That will work well for high torque. A dust guard should be on top. Width of overall tiller should be 42", so hopefully 3' of tilling width. We can do 1/4" thickness for the chain link pieces. 

=Wed Oct 4, 2017=
Finished Bobcat quick attach mounting plate: [[File:Bobcat-QA-mounting-plate.FCStd]] 
About 2hrs for QA plate 
Uploaded files for standards of quick attach 
Next thoughts: update in tractor model 
I was pretty frustrated with the lack of construction geometry in FreeCAD. It's not even possible to create a construction plane, or to set an offset distance for a pad or pocket. This makes it SUPER difficult to get things done when you are used to SolidWorks or the like. Also, mapping a sketch to a sketch face, then mapping out the edges takes way too much time for my liking. Those would be fun things to improve upon...

Some work for implements on the tractor: A 2-pto motor brush hog. Rotor direct coupled to motors. Use Abe's new motors, 5 cu in. The cutter is a cross, 8" wide, with 8" of chain welded to tips. So each cutter has a 24" overall diameter. Thus we get 48" of cut from an implement that 
A coumter-rotating time tiller driven by two high torque motors, same profile of motors as the 5 cu in. Motors ride on top, and are linked to the shafts via 100 chain [http://www.rollerchain4less.com/100-1R-X-10FT-Standard-Roller-Chain_p_830.html?gclid=EAIaIQobChMI1-23yfnZ1gIVkbrACh0xeQNdEAQYAiABEgI0qPD_BwEBut here], since that is so expensive (including sprockets), please just use our existing 8 tooth sprocket and chain links without track pads as in our tracks. That will work well for high torque. A dust guard should be on top. Width of overall tiller should be 42", so hopefully 3' of tilling width. We can do 1/4" thickness for the chain link pieces.

Next thoughts: update in tractor model 
I was pretty frustrated with the lack of construction geometry in FreeCAD. It's not even possible to create a construction plane, or to set an offset distance for a pad or pocket. This makes it SUPER difficult to get things done when you are used to SolidWorks or the like. Also, mapping a sketch to a sketch face, then mapping out the edges takes way too much time for my liking. Those would be fun things to improve upon...

Big tractor projects are:
*tensioner mechanism 
*loader arm reconfiguration 
*idler shaft mounting? 

=Fri Nov 3, 2017=
Planning out next parts to model up 
Found [https://www.coursera.org/learn/fluid-power this course on fluid power] on Coursera. Seems cool! 
If it becomes useful in the future, Open source equivalents to Matlab/Simulink = Octave/Sci Cosim 
Came up with some cool ways to cut out the loader arms by hand by taking measurements from a 2D sketch, which part sketch can be found here

Day 5 of tractor build. We got the tractor running and Marcin drove it around. It has A LOT of power 
The tensioning mechanism and motor mount configuration definitely has the most work that needs to be done. 
Need to do some quick research into finding a good crash course on hydraulics 

=Sun Oct 29, 2017=
Day 4 of tractor workshop 
Spent the morning helping figure out the situation with the sprocket and motor mount attaching to the tensioner. This was a pretty major issue that prvented us from getting the tractor running today. I really do think we'll get it running early tomorrow. 
There could be a better way to mount the shaft with a single collar bolted to the bottom of the frame. Eliminating the shaft clamp and motor mount plate in favor of a single
Spent a good chunk of the afternoon figuring out the cuts for the second piece of the loader arms. Check out the doc [https://docs.google.com/document/d/1FG4wOzv64sImBDVfdeiitX74Q6akCFXsgZ-b3uA86UE here] . I'm actually really impressed we were able to build them up and tack them with just a torch, grinder and welder. It's been a really powerful experience to recognize how little is necessary to actually build these machines and get them going. 
I've been really impressed at what can happen when you get so many people together to work on a project like this. 
We worked until about midnight-thirty to get the loader arms set up, tighten and check that the tensioning mechanism works. 
I was also feel like we could really drop the size of the power cube more by reconfiguring the cooler, engine configuration and the motor coupling. 

=Sat Oct 28, 2017=
Day 3 of tractor workshop 
Spent a good portion of the day learning FreeCAD drawing dimensioning workbench to get some dimensions for the loader arms 
After the frame was welded up, I welded on the motor mount plate and we were able to get the power cube running 
Cut out some 1 bolt shaft clamps in the evening 
I think it has been really valuable to have some solid CAD to be able to pull from and tweak and draw up to make sure things fit together well 

=Fri Oct 27, 2017=
Day 2 tractor workshop 
Spent the morning doing some FreeCAD dimensioning and drawing for Power cube (future power cube cut lists like [https://davehakkens.nl/community/forums/topic/shredder-dxf-laserfiles/ this] would be great) 
We got the flat parts of the frame all cut out and welded up for the power cube 
Welds weren't perfect, and had to be majorly ground down.

Wow, vibratory plows are badass.... links: [https://www.youtube.com/watch?v=4Vb7-ZEW5vE here] and [https://www.youtube.com/watch?v=5LHObecYJwU here] 
They call it a "pipe puller" on the Toro Dingo. I think this is probably closest to what we want: [https://www.youtube.com/watch?v=u6OccLSLVOI here] and [https://www.toro.com/en/professional-contractor/compact-utility-attachments/dingo-vibratory-plow-22911 Toro Dingo Vibratory Plow] 
 
Spent some time working on some FreeCAD stuff with Lex (GT2 Pulley) 
I'm thinking it would be nice to have a CAD work "best practices" page put together if it doesn't already exist, trying starting with something like this: [http://homepages.cae.wisc.edu/~me231/online_notes/cad/modeling%20practices.pdf Best CAD Practices] 
 
Also, planning to head out to Factor e-farm for the tractor build at the end of October 
 
Implement talk from Marcin: 
I'd like to add one implement request before mower and tiller. It turns out that we need to trench 800 feet of power line to the seed eco-home for backup as we test the off-grid PV system at the Seed Eco-Home. Can you do a vibratory trencher as the first implement? It needs to go down only 12". Now you have the female mount, you can use that on it. Because microtrac is 41" wide, we also want to have a QA female that is 41" wide. Both would work if we make our male part a little more narrow. The pin locations are the limiting factor - but we have flexibility there as there are 2 pin locations on each side. 
 
See vibratory plot for insderting cable - https://www.ditchwitch.com/trenchers/vibratory-plows/410sx - on the back of thiis ditch witch. It is just a motor with a non-balanced weight on the rotor. We can use Abe's 5 cu in motor - http://opensourceecology.org/wiki/File:PTO_Hydraulic_Motor.fcstd

Redrew mounting plate with sheet metal approach: [[File:Bobcat-QA-female.FCStd]] 
The sheet metal add-on worked great (you can find it [https://www.freecadweb.org/wiki/Sandbox:Sheet_Metal here] ). My only qualm is the the bend feature doesn't have options for things like material added on the outside or inside or distance offsets. The radius also adds length to the total flange, which is unfortunate. Maybe we could get some programmers on that?

Some primitive 2D sketch work on the vibratory plow, just for conceptual design, done in [https://docs.google.com/presentation/d/1FzlT3ZO4UANPsI6deq-4haAOYmi3u-XF07WfMrk1bKg/edit#slide=id.g27cb7bfd62_0_34 This Doc] 

Wow, vibratory plows are badass.... links: [https://www.youtube.com/watch?v=4Vb7-ZEW5vE here] and [https://www.youtube.com/watch?v=5LHObecYJwU here] 
They call it a "pipe puller" on the Toro Dingo. I think this is probably closest to what we want: [https://www.youtube.com/watch?v=u6OccLSLVOI here] and [https://www.toro.com/en/professional-contractor/compact-utility-attachments/dingo-vibratory-plow-22911 Toro Dingo Vibratory Plow] 
 
Spent some time working on some FreeCAD stuff with Lex (GT2 Pulley) 
I'm thinking it would be nice to have a CAD work "best practices" page put together if it doesn't already exist, trying starting with something like this: [http://homepages.cae.wisc.edu/~me231/online_notes/cad/modeling%20practices.pdf Best CAD Practices] 
 
Also, planning to head out to Factor e-farm for the tractor build at the end of October 
 
Implement talk from Marcin: 
I'd like to add one implement request before mower and tiller. It turns out that we need to trench 800 feet of power line to the seed eco-home for backup as we test the off-grid PV system at the Seed Eco-Home. Can you do a vibratory trencher as the first implement? It needs to go down only 12". Now you have the female mount, you can use that on it. Because microtrac is 41" wide, we also want to have a QA female that is 41" wide. Both would work if we make our male part a little more narrow. The pin locations are the limiting factor - but we have flexibility there as there are 2 pin locations on each side. 
 
See vibratory plot for insderting cable - https://www.ditchwitch.com/trenchers/vibratory-plows/410sx - on the back of thiis ditch witch. It is just a motor with a non-balanced weight on the rotor. We can use Abe's 5 cu in motor - http://opensourceecology.org/wiki/File:PTO_Hydraulic_Motor.fcstd

DFM on the bobcat standard quick attach 
[https://docs.google.com/presentation/d/15g_Bm7r5jm8YzJb0kfjyAI4Now42G09fgGZuqId1CnE/edit#slide=id.g27bf2a97b9_0_2 Pictures and Links] about quick attach plates 
Redrew mounting plate with sheet metal approach: [[File:Bobcat-QA-female.FCStd]] 
The sheet metal add-on worked great (you can find it [https://www.freecadweb.org/wiki/Sandbox:Sheet_Metal here] ). My only qualm is the the bend feature doesn't have options for things like material added on the outside or inside or distance offsets. The radius also adds length to the total flange, which is unfortunate. Maybe we could get some programmers on that?

Some work for implements on the tractor: A 2-pto motor brush hog. Rotor direct coupled to motors. Use Abe's new motors, 5 cu in. The cutter is a cross, 8" wide, with 8" of chain welded to tips. So each cutter has a 24" overall diameter. Thus we get 48" of cut from an implement that 
A coumter-rotating time tiller driven by two high torque motors, same profile of motors as the 5 cu in. Motors ride on top, and are linked to the shafts via 100 chain [http://www.rollerchain4less.com/100-1R-X-10FT-Standard-Roller-Chain_p_830.html?gclid=EAIaIQobChMI1-23yfnZ1gIVkbrACh0xeQNdEAQYAiABEgI0qPD_BwEBut here], since that is so expensive (including sprockets), please just use our existing 8 tooth sprocket and chain links without track pads as in our tracks. That will work well for high torque. A dust guard should be on top. Width of overall tiller should be 42", so hopefully 3' of tilling width. We can do 1/4" thickness for the chain link pieces.

Finished Bobcat quick attach mounting plate: [[File:Bobcat-QA-mounting-plate.FCStd]] 
About 2hrs for QA plate 
Uploaded files for standards of quick attach 
Next thoughts: update in tractor model 
I was pretty frustrated with the lack of construction geometry in FreeCAD. It's not even possible to create a construction plane, or to set an offset distance for a pad or pocket. This makes it SUPER difficult to get things done when you are used to SolidWorks or the like. Also, mapping a sketch to a sketch face, then mapping out the edges takes way too much time for my liking. Those would be fun things to improve upon...
