[[Seed_Eco-Home_Scale_Model#Part_Library]]

=Monday Mar 16, 2020=
-Adding drive assembly, bolt holes and guards (10 hrs)

Updated file: https://github.com/nsuitter/OSE/tree/master/Bandsaw_Mill

=Sunday Mar 15, 2020=
-Working on putting 3D model into TechDraw views (6 hrs)

=Saturday Mar 14, 2020=
-More bandsaw work (6hrs)

Note: I created this using is using FreeCAD v0.17. It will appear messy in v0.15

It says the file is too big to upload. Posted it here: https://github.com/nsuitter/OSE/tree/master/Bandsaw_Mill

- Printed off two models and tested out the magnet connectors--worked like a charm. They fit in loosely in the field and press fit around the perimeter. I used super glue to fix them in place.

=Tue Apr 2, 2019=
- Uploaded all existing models in the part library in the new 1:20 scale

=Wed Mar 27, 2019=
- Created model for exterior wall with door [[File:Door-(4x8x6 5)-Opaque.fcstd]]

- Fiddled around with Linux (kept on getting logged out of my session)

[[File:Door_(4x8x6.5)_Opaque.png|400px]]

=Tue Mar 12, 2019=
- Created Python tutorial for FreeCad [https://youtu.be/_vpDwS4cMB4]

=Sun Mar 10, 2019=
- Doubled size of magnets, and scaled model to 1:20 [[File:Wall-Insulated-4x8x6 5(1-20).fcstd ]]

- Created connector since increasing the magnet size leave less space for connecting the panels [[File:Connector.fcstd]]

- Updated the script for configurability [https://github.com/nsuitter/FreeCadScripts/blob/master/whole-shape-plus-holes.py]

=Wed Feb 27, 2019=
- Doubled scale of one module [[File:Wall-Insulated-4x4x6_5(1-12).fcstd ]]

- Updated python script to handle magnet thickness changes and uploaded to [https://github.com/nsuitter/FreeCadScripts/blob/master/whole-shape-plus-holes.py github]

=Fri Feb 22, 2019=
- Created simple model in FreeCad

[[File:Simple_OBI_model.png|400px]]

=Thu Feb 21, 2019=
- Added ten more modules to library

- Wrote [[File:OBI-Model-Script.tar.gz|python script]] to automate creating and putting pockets into rectangular modules

=Wed Feb 20, 2019=
- Added four more modules for scale model library

- Fiddling around with Python to automate this process but running into pocketing issues in FreeCad

=Tue Feb 19, 2019=
-Finished hidden magnet designs for three modules

-Added [[Seed_Eco-Home_Scale_Model#Part_Library]] to wiki.

Marcin sent me a link to [[https://www.iliketowastemytime.com/2015/05/29/clever-use-of-3d-printing-modular-magnetic-kitchen-construction-set-mmk this project]] and it made me think of hidden magnets where you didn't need to print them in, thus using fewer magnets, skipping the two-step printing process, and maintaining clean faces. Here's what I came up with. Less symmetrical modules would have two parts but for this one you can simply print off two for one module.

[[File:Hidden-Magnets Model.png|600px]]

=Tue Feb 12, 2019=
- Made a couple connector options

Option 1:
[[File:Option1.png|800px]]

Option 2:
[[File:Option2.png|800px]]

Option3:
[[File: Option3.png|800px]]

- Learned a little Python to make modelling a little faster

=Sat Feb 2, 2019=
- Started on adding pockets for magnet connectors for scale model [https://drive.google.com/file/d/1GspbADStrvagVUwDQ7fq9hcyrBhPvARj/view?usp=sharing]

- Need to double scale to accommodate magnets

- Started on macro to be able to select face and add pockets automagically

=Mon Jan 28, 2019=
- Started learning the FreeCad API (1.5 hrs)

- Caught up on last weeks meeting (30 min)

=Sat Jan 26, 2019=
Started [https://docs.google.com/presentation/d/14LJhfMNzmSSPZTbnZB4pVGi0vHLH6BzMr109lg2mY70/edit#slide=id.g45ed589c64_0_0 design doc] for scale model connectors (1hr)

=Wed Jan 16, 2019=
- Created two FreeCad 3DP [https://drive.google.com/drive/mobile/folders/0B0NG-lv1ELQvaFFPODM1MURIR0k/0B0NG-lv1ELQvQnNJNjQ4aWlLWUE/1Svhi3Iir4KxpYnZqw76trVwKHfojRJ2N/1BcIUi86c2UnoNDNtBlxIoZ4Z2LoDXXqL?sort=13&direction=a files] (2 hrs)

Adding a dot in the file names of FreeCad files creates a zip with no *.fcstd file (I’m sure this is in the docs somewhere but didn’t bother looking it up) and I try to avoid spaces in my file names so “Wall 4x4x6.5” became “Wall-4x4x6-half”

=Tue Jan 15, 2019=
Added [[Seed Eco-Home Scale Model]]

=Mon Jan 14, 2019=
Started recreating a file from OBI website in FreeCad for practice. Had 2 question as a result:

- What scale should the models be at? (We decided 1/4” for now)

- Is there any special way we need to treat the layers for 3DP files?

=Wed Jan 2, 2019=
Alex Au emailed saying Nathan would like to make 3D printed versions of the open building institute housing modules. He has some background in building housing structures and is also happy to proofread the housing manual.

# Installing OSE Linux
## OSE Linux Live USB, 5 hours
## Getting file/system configuration persistence across boots, 15 hours
## Trying and failing to get linux to recognize my Mac keyboard and mouse, 5 hours
# Learning FreeCAD, 20 hours
# Documenting work
## Making video, 1 hour
## Editing video, 1.5 hours
## Making work log, 30 minutes

Getting linux working to my usability standards was the most time consuming. Took a little bit to figure out planes/changing degrees of tubing in FreeCad but it's pretty easy to understand after a bit of practice. All the information needed to complete the test was in the tutorials but I did some searching on my own as well to understand some concepts a little more in depth.

'''Score: 90'''

Couldn't find the driver to get my mic working on Linux. Had to add the audio and edit the video on Mac. Voice is super quiet on video.

Hi Nathan,

The task is actually not that complicated. The modules are all well-defined as in the presentation. So in there, combined with the basic Design Guidelines that I outlined, you should be good to go.

Regarding the updated modules - it turns out we don't need that level of detail for the model kit. Because the modeling kit is designed for design assistance, not technical build details, it suffices to use very simple models. As long as they look correct, that is sufficient - the interfaces between them are not critical. So as long as we design the magnet holes into the pieces, that is sufficient. So you should be able to get going in earnest based on the above presentation. A good test of your success would be to take the modules that you design - and replicate a simple structure like the simple Studio in the presentation. Don't worry about the interior - as long as we make an attractive design that looks good from the outside - we are good. That means that the panels may want aesthetic features such as the wood look on the real build of the 2016 Seed Eco-Home. But these are all details that can be added - so as long as you complete the first complete set of modules, we can improve them after we test that they work for building the model. You can test whether they work by assembling sample models in FreeCAD.

So go at it - and let me know if you have any questions.

Marcin
