wow! I just discovered this and immediately I want to build it . I downloaded the file from github, do I need any other files to produce it?

  Are you sure? yes | no

Nope, thats complete project. You have two versions of PCB- with mechanical buttons(venom) and with darlington touch sensors(sense). Ever folder habe "output" inside with gerber files. You can program MCU via SWD 1,27 connector using st link(e.g. from any nucleo-64 board). You need stm32 cube programmer for flash MCU.

Would love to buy this as a kit, good job!

Thanks. I can send you a gerber and MCU batch, but you have to order PCB and components by yourself. In poland now i cannot buy magnetometer(LIS3MDL).

I really like that it has an ohmmeter and DC voltmeter and does NOT have any fitness tracking junk.  This is way more useful to me than all the commercial offerings I've seen so far.

Thansk :) You have the same perspective like me :P
