Building an AUTOMATIC MUSIC BOX - HELP!

  1. Jun 1, 2012 #1
    Hello everyone,

    I am a music composer and total noob. So please excuse my lack of engineering knowledge.

    I am attempting to build a music box that can play without having to turn the gear's crankshaft manually. Here is a picture of the music box:

    I have been doing some research and think I have a rough plan. Please correct me if I am wrong, I think I need a DC motor like this one:

    Do you guys think this is a good motor to turn the gears? I also want to be able to change the speed so I guess I'll need a rheostat or potentiometer. Which is better and what specs do I need? Will I need to match the voltage of my motor?

    What batteries are good for this? I would like to save space so if I get two 9 volts = 18V will this be too much for my little 12V motor?

    Is there a good package kit that has a motor and speed control together?

    thanks ahead of the help and advice!

    UPDATE, what about these?

    hobbyengineering.com/H2031.html (assemble at highest gear
    ratio / slowest speed)
