  • The music kit I bought came with a hole punch and paper, so you can get started right out the box. There are ones that are around 10 dollars cheaper but use plastic gears which I heard wear down easily. If you don't mind hand cranking it, you can just toss it in a woodbox and go from there.

  • Here's the motor and speed controller that I used in my build. You just need to hook up the motor and a power source to the speed control, and then find a way to mechanically turn the crank with the motor. I just used a hex coupling to attach a piece of stiff cardboard to the end of the motor shaft which turns the crank. It might be easier to just go with a motor-run music box instead, that way you just need to clip the wires and hook up to the speedcontrol (or just use as is if you dont need to adjust speed!)


  • The wheel was made from two film reels I found in a local garage sale with some nuts and a threaded rod, and it's held up by two wire coat hangers that I bended to fit.

  • The paper with the actual song on it needs to be hole punched for each note, this is a great site where you can fully program a piece to see how it would sound before actually punching the paper. It also lets you export the piece as a pdf with x's on the exact places to punch holes so the process is a lot cleaner.

    Other than that, its just woodwork to frame all the parts into one piece, where there are a ton of better resources than me on the subject. Keep in mind just settling on handcranking the box is loads of fun on its own.
    Feel free to pm me if have any more questions on it and good luck if you actually decide to go for it!
