Idle hands, part deux.

I made a post a while back in the lines of "ube finds work for idle hands". Here's part two.

There's a post over here at vintage is the new old detailing a audio separation solution. I looked at it and thought "cool, this ought to be expandable" and so it is. So I:

  •  Added a 4-1 mux.
  • Added a volume potentiometer
  • Added an input board (Display plus rotary encoder).
  • Added usb power (and usb functionality on the input board, not tested.)
Code is done. I'm waiting for the single RCA so I can test everything. Size? The PCB is 100x30mm..
