Hey,
First of all I'd like to confess that I really have no electronics background, so I have no idea about anything in this field.
For a friend's birthday, I have bought the Kikkerland Music Box DIY Kit, which lets you punch holes in a music strip, which the accompanied music box plays. However, this "music box" works by manually turning the small lever, you can see a photo of how it looks here:
https://www.kikkerland.com/products/make-your-own-music-box-kit/What I would very much like to do is somehow make it turn "on its own", i.e. without my friend having to turn thr lever continuously each time they would like to hear the music.
The only thing I could think of is to get one of those small simple motors, and attach a "lever" to it so that it will spin the music box lever. However, from what I know these motors spin very fast, and the music box lever needs to be spinned pretty slowly (imagine as if you're turning it with your hands, it's not that fast.
So as you see I have no idae what I'm doing, but this is very important to me and I would really like to find a solution. This means I need to find a solution that will turn the lever in a normal speed - a speed that I cannot define, so it would be great if I could play with it until it is just right. You can see an example of the speed needed in this video (05:10 mark):
However it could be a bit slower I guess.
I would really appreciate anyone's help in this matter.
Thanks!
