The RMKMC is a 3D printed, ESP32-powered musical instrument and controller. It features 8 keys, each assignable to different tones, and a touch-detecting mechanism facilitated by 30 cm-long breadboard cables hidden beneath the keys. The RMKMC communicates via Bluetooth with a smartphone or PC and acts as a standard keyboard. It also includes a hidden smartphone mount with print-in-place hinges and a unique release mechanism, making it perfect for streamers. The RMKMC can also communicate with OctoPrint for basic 3D printer controls. More details can be found here.
The assembly requires minimal hardware and no soldering. The design is also support-free. Please refer to the detailed assembly instructions provided here.
The firmware for the ESP32 microcontroller is provided in this repository. To upload the firmware, you will need the ESP32 flasher. After uploading the firmware, your musical keyboard is ready to play.
