Moscow-based media artist Dmitry Morozov Has created an awesome electromagnetic/electromechanical organ called the Motorgan using and Arduino Mega development board.
Watch the video below to learn more about the interesting project and listen to the unique sound. The Motorgan organ is equipped with two different sized PC cooling fans together with a gear motor and a keypad for each motor which allows it to create a variety of different sounds.
– 3 dc motors (2 PC pc cooling fans and 1 motor with gears)
– arduino mega
– single guitar pickup
– 24 keys touch keyboard
– 6,3 Jack output.
– digital voltmeter for tuning
– 24 potentiometers for voltage control

Each of the 24 keys can be tuned with a potentiometer, which reportedly allows one to “make any kind of music.” The speed of each motor is controlled by voltage changes via touch keyboard with 24 keys. Keyboard is split into three parts (registers) for each motor, so it’s possible to play chords/polyphonic lines by taking one note from each register. Electromagnetic fields produced by motors are picked up with a single coil guitar pickup.
