RimstarOrg | How to Make 555 Timer Music Player and Maze Solver @RimstarOrg | Uploaded 11 years ago | Updated 8 hours ago
How to make a music player using the 555 timer chip, as well as a maze solver. This shows how the player head is made as well as the resistances for the pencil mark/graphite variable resistors.

The step-by-step instructions for making the 555 timer circuit can be found my other video here "555 Timer Music Instrument How to Make":

As a quick add-on, it also shows how to solve a maze using this same circuit.

For the webpage with written details about this music player and with the spreadsheet I mentioned in this video, go here:

The idea for the maze and the original idea (though I took it in a different direction) for the music player came from:
