Really small analog gauge controlled by simple circuit Answered

I'm looking to make a steampunk version of dr who's sonic screwdriver with some LEDs, a tiny recording module for the sound, and I also wanted a little analog gauge with a needle that would activate when the button was pushed. It doesn't have to actually measure anything, I just want the needle to move in some way.

i found a little voltmeter on sparkfun that I could probably repurpose, but it's 2x2 inches which is a little bigger than I wanted.  I'm looking for something about half that size.

Does anyone know of anything that would fit the description, or a way I could fake it?

Search ebay for "battery tester", some will have small analog meters. You'll have to disassemble one, but many are cheap ($2-$3 USD).

Lots of vintage light meters (photographic eq) have analog gauges that might be small, too.

If it's cheap enough for the risk, the mechanism of the volt meter might be small enough to be worth making a new dial and trimming down the needle to fit.
