Suggestions for DC Motors that DO make noise

Hi all,

I found a number of posts regarding reducing noise from DC motors but I'm actually looking for suggestions of motors that produce a good amount of noice, mechanical or electrical.

I'm looking to create a soundscape with multiple motors spinning with variable PWN signals.

Thanks for the suggestions.

If your motors have screws and/or nuts holding them together, begin loosening them until you get the sound you want.

Any motor with spur gears, especially if an open-framed gearbox. Cheap is good too. Don't expect long-life though.

And steppers driven in full steps.
