I want to modify a music box to play an old midi I composed.

too difficult and too much failure point of a noob project, you gotta learn casting at small scale and make it accurate so it will fit into the box... yeah that is not very likely it will work first time, in fact you should expect fuck ups several times to get something complicated like this right

but for notes to play quicker, just make it go faster or salvage two music box and make them play together

might be better off building the whole thing from scratch, might not be small but could be a nice art object in it's own right

FOUND IT OP! MAKE LIKE THIS BUT MAKE FROM LEATHER? AND MAKE IT ROLL UP. maybe some other. Would be a fucking shoebox size but get or make a program that can do the dots and punch them. Gold.

Get several of the tines and put them on a rotating drum, then make electronically controlled pins to strum them when they rotate past. This way, you have a programmable music box, and it should be easier to do than making your own drum.

That is a fucking amazing idea anon. Thank you.

OP here. Man, am I glad DIY moves slowly. Thanks for all the suggestions, guys. I'm still not sure what I'm going to do yet, but I really appreciate the help.

:) it's why i'm here bro. Hand awl thats sharp should be perfect for it.

Personally I would suggest using thin sheet metal, punching the notes by hand, and then wrapping it around a cylinder.

Forget about all of that. Get some round stock steel of the correct diameter, layout and drill small holes, then hammer in small tacks and clip them to length.

Could you put a current through the thing so when one of the bits hits a bump on the wheel it creates a circuit and a buzzer sounds at the right pitch for each note?

Why not just make a tab that strokes the tines and drop the drum altogether?
