555 Timer Chip Scroll Music Player


Check out this 555 Timer Chip Scroll Music Player, it  uses scroll that has a bunch of slots cut into it so that metal fingers can selectively touch a contact under it. A rolling system pulls the paper past these fingers and plays music since each contact has a different resistor value connected to a 555 timer. The construction looks great since you can see all of the components.
