I started dabbling with this project in November of 2019, and by the end of the month I had sent the first PCB design to the board house.  This is what that board looked like.

There were numerous design errors with the board.  The power jack was wired backwards, there were various bodges necessary on the PCB to get things working, but it was not bad for the first run.  In total, 5 of these boards were made.

Show here is what's left of an early prototype, that's had some disassembly and troubleshooting done after testing.

Lessons learned, and we were on to Rev 2.
