Today read about versioning and devtemplates.

Lots of useful information. Next: Create dev template and add some requirements. Have roughly 1 hour per day on average this week. </p> <h2><span id="Wed_Oct_29.2C_2025"></span><span class="mw-headline" id="Wed_Oct_29,_2025">Wed Oct 29, 2025</span></h2> <p>Started to read a book: DIY Lithium Batteries - How to Build Your Own Battery Packs. </p><p>Need to look through the prior art on the wiki: <a href="/wiki/Open_Source_Battery_Pack" title="Open Source Battery Pack">Open_Source_Battery_Pack</a> </p><p>Haven't received any confirmation mail for my time log request, it gives a 404 at the moment, will try again later. </p><p>Did steps 1-5 of <a href="/wiki/Get_Involved_in_Global_Documentation" title="Get Involved in Global Documentation">Get_Involved_in_Global_Documentation</a>. 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. </p> <h2><span id="Tue_Oct_28.2C_2025"></span><span class="mw-headline" id="Tue_Oct_28,_2025">Tue Oct 28, 2025</span></h2> <p>Finished the Get Involved In Documentation video. Nice details in the FreeCad.

Looked at <a href="/wiki/Cordless_Drill_Construction_Set" title="Cordless Drill Construction Set">Cordless Drill Construction Set</a> and youtube videos about the Open Source Blueberries. </p> <h3><span class="mw-headline" id="Drill_Notes">Drill Notes</span></h3> <p>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. </p> <h4><span class="mw-headline" id="Battery_pack">Battery pack</span></h4> <ul><li>Ryobi battery is 18V 2.5Ah = Five 18650 cells in series. Can just go for that.</li> <li>Challenge with 18650 is that a Battery Management System is basically mandatory for Li-ion, to not burn down all the Seed Eco homes.</li></ul> <h4><span class="mw-headline" id="Off-the-shelf_vs_make">Off-the-shelf vs make</span></h4> <p>Chuck - 13mm, 1/2" - No metalworking in v1 -> Buy. Cells - No brainer -> Buy. Body -> Print Battery pack -> Make, because I want to learn about it. Motor -> Buy in v1. Needs more research. Some suggestions here: <a rel="nofollow" class="external free" href="https://wiki.opensourceecology.org/wiki/3D_Printed_Drill">https://wiki.opensourceecology.org/wiki/3D_Printed_Drill</a> </p> <h4><span class="mw-headline" id="Order_of_operations">Order of operations</span></h4> <p>I'll start with the battery pack, because it sounds like fun and is a complete module that I can test and verify without dependending on any of the other parts. Should I go straight for the dev-template? </p>
