Here's what you need:

Each of these meters has a moving-coil electromagnetic movement that
requires only a tiny amount of power to activate. Remove the plastic
cover and glue a piece of paper or aluminum foil to the indicator
needle and you're off. You'll probably have to operate them with the
meter and paper facing downward or you'll have trouble with stability
because the weight of the paper will unbalance the meter movement.
Price: I believe they're under a dollar for the small ones. Downside:
you have to order from China. Try requesting a few samples. You can
also find these things in surplus stores and on eBay.
