This project was a really difficult, it was 70% timing and 30% execution. Many people have seen videos with floppies and stepper motors playing songs. These motors have a quick response time because they are not under a heavy load. The problem with a flatbed scanner is the large moving carriage head. It was not designed to move quickly and when it is playing music you will notice the head changes directions. This is to prevent the carriage from smashing into the chassis. So as the notes are playing the carriage head has to periodically change direction and this will add many seconds to a 3 or 4 minute song. As for the drums they are just a couple of solenoids connected to a pulley system in order to ampilfy the movement.
