Thanks for the writeup I found similar difficulty parsing all of the software and firmware. The expectations of prior or "basic" knowledge throughout was frustrating. what's EEhands? or which bootloader? what's a bootloader?

I'd estimate 10 hours to build and 30 to get the software working which surprised me as I thought the software would be the easy part going into the project. A great learning experience though, and let me dip my toe into hardware development which was a nice side bonus.
