Requested a time log. Started to watch Get Involved In Documentation

Hello world. Looked at [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.

Off-the-shelf vs make

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: https://wiki.opensourceecology.org/wiki/3D_Printed_Drill

Order of operations

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?
