It was interesting to see this type of motor being driven directly from Arduino outputs. I have dumped all my old hard drive motors as I didn't think I would be able to do anything with them, but should I ever come across another one I might try this out.

I once tried to use an old cassette tape play to make an animation for a bill board once, it worked but not that well. It wasn't designed to be outside all the time!

Very useful information. Last week I took apart 2 hard drives, each one was different but similar. (I like the strong magnets inside for attaching things to my metal cabinet). I applied a few volts to those 4 pins, and noticed each would rotate and stop. I was thinking they might be stepper motors, and I would connect them to an L293D or something. But this sounds a bit different.

Nice one, Nico. Looking forward to seeing the finished result.
