The creator’s objective was to construct an enormous flooring piano utilizing available and cheap supplies. The result’s astounding contemplating it was constructed fully at dwelling.
The present model price him $ 300 per octave (primarily as a result of wooden and translucent acrylic, and about $ 50 for electronics) and $ 50 for the grasp. It took me about 60 hours to construct.
For every octave there’s an Arduino Mega, an MPR121 module, a PWM driver, a number of transistors and several other meters of RGB LED strips. An Arduino Mega and a MIDI defend have been used for the Grasp module.
