- Advancing digital piano actions by replicating a grand piano action with electromechanics.
- A PCB for controlling current through solenoid, and force feedback applied to a piano key to mimic a grand piano action in a digital piano.
- For precisely controlling the current through a solenoid in realtime
- Controls current linearly (calibrated with 2-pt calibration curve)
- Controls direction with PMOS/NMOS H-bridge + drivers
- Controlled with a DAC (used stmL432KC)
- Made in Altium
