O.MG Cable: Malicious USB Cable with WiFi

I had not used “real” PCB design software before, used a desktop mill to cut boards, worked with solder mask, soldered things this small/cramped, played with this level of code, etc. I also wanted to do as much as possible on the mill instead of sending the boards off to be professionally made. Bantam, the manufacturer of this desktop mill, has actually reached out to me so we can polish up the PCB creation process and make it so others can reproduce this quality of PCB for themselves.
