			Did steps 1-5 of [[Get_Involved_in_Global_Documentation]]. Learned how to hide/unhide and how to rotate the view in CAD navigation style. I am using FreeCad 1.0.2 on Windows at the moment. Was able to open the SEH6 file without issues, but had to accept a preprocessing step.

Hello world. Looked at [[https://wiki.opensourceecology.org/wiki/Cordless Drill Construction Set]] and youtube videos about the Open Source Blueberries.

=== Drill Notes ===
Seems like a good project for me to learn about power electronics, CAD and get started with prototyping.
I have a Ryobi RCD1802 that I will use as inspiration and benchmark. Costs roughly $150 here in Norway including battery and a bag.

==== Battery pack ====
* Ryobi battery is 18V 2.5Ah = Five 18650 cells in series. Can just go for that.
* Challenge with 18650 is that a Battery Management System is basically mandatory for Li-ion, to not burn down all the Seed Eco homes.
