Inputs to the controller were wired in place. At first, this was going to be a matter of soldering wires to the MIDI FeatherWing, then soldering that to the controller board, but this would have made any modification difficult because the wires would have been between the two boards and inaccessible. The two PCVs were soldered together, and then the inputs were soldered from the top. Care was given to make sure the wires would reach once everything was placed in the case.
The Feather boards allow a switch to enable or disable the onboard voltage regulator, but I did not research this in time, so I added a switch to the battery line, which is not the worst solution. Shrinkwrap protected the switch and wires but had a hole cut to expose the switch plunger.
Some double-sided foam tape held the battery to a blank spot on the protoboard, and everything fits neatly into the case. A speaker proved the sound module still worked, and flipping up the end will easily expose the connectors and switch.

Switches and potentiometers wired up
The Feather boards allow a switch to enable or disable the onboard voltage regulator, but I did not research this in time, so I added a switch to the battery line, which is not the worst solution. Shrinkwrap protected the switch and wires but had a hole cut to expose the switch plunger.
Battery and power circuit
Some double-sided foam tape held the battery to a blank spot on the protoboard, and everything fits neatly into the case. A speaker proved the sound module still worked, and flipping up the end will easily expose the connectors and switch.
Self-contained except for speaker/headphones
