#575 Motorized Music Box

A quick test of motorizing a hand-cranked music box.

Here’s a quick demo..

Notes

Some timeback I purchased a Mini Hand Cranking Movement Music Box from a seller on aliexpress with a view to incorporating it into a model of some sort.

I cut the handle off the music box and connected a geared DC motor to drive it.

Construction

Result

The motor is actually geared for 60rpm at 6V, but I’m driving it at a very low 1.5V. This slows the music down, but is not ideal as the torque is a bit low and leads to warbles.

There is too much motor noise for this to be a nice idea, so I’ve shelved it for now and it won’t be making an appearance in the kit I had planned.
