Programmable Music Box

Created on 28 Nov 2015

Programmable music box created by changing the comb and not the pins

A music box that can be reprogrammed to play different songs according to user input. Idea is to somehow be able to control the comb and/or pins within the music box to modify the songs the box will perform. Stetch goal is to get a digital interface that can program near instantaneously.
