I made a new controller for the Musical Crystal Cave! This one has very Myst-y vibes and I'm very pleased with how it came out. This is a 100% custom controller that's largely 3D printed (except for all the wood).
The levers use magnetic rotary encoders and connect wirelessly via espnow to a dongle that outputs MIDI CC. I drive the animation of the artwork via TouchDesigner.
CAD was split between Openscad and OnShape.
