From the project
hardware UI for voctomix
This is a hardware-interface vor voctomix, developed late 2017 and tried in a few talks at 34c3.
Custom PCB Cherry MX switches with custom 3D-printed keycaps 3D-printed top and bottom enclosure parts “sandwiched” around the PCB Arduino Nano which sends commands to a computer via USB Computer relays the commands to the voctomix software via socat is supposed to learn to speak TPC on its own (was not implemented on 34c3)
