I have a bunch of 1mA meters, but no 50-0-50 or 1mA-0-1mA meters...
I'd like some hints as to how I might modify, or create a circuit
that centers the needle in the middle of the scale. Like if I wanted
to make a meter for measuring positive and negative current flow,
like you might use for a vehical alternater/gen charging system. I'm
guessing I'll need some kind of active circuitry...
