Piano Exciters

CONCEPT :

For this project we are creating a device which can excite the strings of a piano (or potentially any string instrument). This exitation is meant to be created by means of spinning motors which create a bouncing effect on top of an instruments strings.

1st ITERATION

This is the electroacoustic project base on DC motors and Arduino and piano as an acoustic instrument. These six DC motors are connected to the Arduino. I use Arduino's relay to control the signal, which is capable of handling and switching high-voltage or high-power circuits. A relay consists of an electromagnet which, causes a switch to close or open.

I put these motors inside the balls to make vibration and these balls will set up on strings of the piano. The sounds consist of a clash of balls with strings and a combination of processing of vibration and acoustic piano.
