Adding input and output (I/O) components such as switches, potentiometers, jacks, and LEDs requires drilling, wiring, and stuffing it all into a box, where it’s hard to debug and modify.
A nicer approach, which I borrowed from early analog synthesizers, is to build handy modules that carry one protoboard each and plug into ...
