my second attempt at a custom rhythm game controller for Sound Voltex
this one uses a PCB. connects via micro usb directly into the raspberry pi pico.
dimensions:
fully assembled: 235 mm x 130 mm x 50 mm (including height of knobs and rubber feet)
- 1x 3d printed case (see picosdvx2-top.stl and picosdvx2-bottom.stl)
- 4x 1.5u keycaps, 2x 2.25u keycaps, 1x 1u keycap (3d printed)
- 2x 3d printed knobs (picosdvx2-encodercap.stl)
- 2x PEC16-4015F-N0024 (encoders)
- 1x Raspberry Pi Pico
- 7x MX-style hot-swap Switches (i used reds)
- 4x rubber feet
- 3x buttons (for controlling)
- 7x per key leds (4x blue, 2x red, 1x green)
- 10x rgb edge leds (ws2812b-5050)
written using circuitpython and the adafruit hid gamepad libraries. make sure to install the required libraries.
this does spoof sdvx eac with a custom circuitpython build. settings configurable in setup.py.
built using kicad, ordered via JLCPCB. 10x PCBs cost around ~100$, including some PCBA.
one button toggles LEDs, another switches between control mappings. last button is currently unused.
