A 22 keys Bluetooth keypad is attached to a Right hand brace. A 2-axis thumb stick (red enclosure) is connected to a MusiMotoSat microcontroller, which is mounted on the back of the keypad along with a Motion Processing Unit. A strip of 2x4 FastLEDs is attached to the top of the keypad to illuminate it and provide visual feedback of the notes played. A 3.7 volts LiPoly rechargeable battery powers the hardware. The MusiMotoSat is connected via Bluetooth Low Energy to the MusiMoto app.
