Using some Arduinos and a few other electronic bits this HP Scanjet 4C is made into a musical device by “playing” the stepper motor. The result is one of the best stepper motor musical items I have seen.
“You may of heard of a popular flat bed scanner named the HP Scanjet. This scanner had a hidden command set within the Scanner Control Language which allows you to send musical notes directly to the stepper motor. This is a tedious method where you have to enter the notes and durations manually into a text file (similar to G-Code on a CNC Machine). I have always used and will always use this method for my Old School music videos however I wanted to try and build a MIDI controlled stepper motor.”
