This is my Diploma projects at Filmakademie Baden-Württemberg
Scannone uses a series of photodiodes to scan the the disk surface.
Inside a 3D printed enclosure there is an array of leds on one side and on the other side their matching photodiodes, if there is some paint on the glass the light won't get trough and the photodiode will close.
Closed diodes will turn on a gate that pretty much works as a keyboard key.
The project was meant to work with a proper scanner sensor, but I was a rookie back then and didn't manage to understand the whole 40 pages of Toshiba documentation.
The devices has its flaws, for example I didn't took in count the internal resistance of the integrated switches I used so the note signal depending on the situation can play out of tune. and the motor is too weak for the system to be used as meant (or maybe the whole device is just too big!)
The motor is run by a stepper motor and an Arduino.
To be used in combination with Scannone I built a drum sampler in a pizza box using a Teensy board
Rotolo is made using a motor recycled from an old hard drive in combination with an Electric Druid Tap Tempo LFO IC.
The crank by rotating the HDD motor generates a 3 wave voltage that is being squarized and fed to the tap tempo IC responsible for the constant clock output
