Does anyone have sources for analog meter movements that can rotate at least
250 degrees? I'm building a custom rate-of-climb instrument for my glider.

I found one source at http://www.us.yokogawa.com/MI/ but their smallest
off-the-shelf unit is a bit large at 50x36mm. It uses taut band technology.

I've been trying to find a source for air-core movments but web searches
only show up people selling automobile tachometers. I'd can drive the meter
with PWM or DAC or whatever.

Thanks, Tom
