I also just discovered a Hobbico volt meter that I had from my RC flying days. Measures down to almost nothing, and it IS voltage only, so a lot of the extra stuff of a multimeter is already gone. It uses a 9-volt battery, but that's the least of my worries. Also, another poster mailed me directly and suggested that a hobby store might have a simple electronics kit for kids that might have one as a project....I'll try Toy-R-Us when they open.

Analog meters (round things) don't require any power to operate. You just need to get one with the right range of voltage or convert your input voltage to the one needed by the meter with a simple voltage divider (two resistors). I don't have a particular meter in mind, but there are oodles of them available from the normal electronics distributors like DigiKey.

All you need to know is the range of readings you want and then you can get a gauge that reads that range. It is quite normal for a voltage gauge to read millivolts, and you can convert your input signal to millivolts to read the way you want. If you decide you want to go that way and want a little help picking out the gauge and resistors just fire me an email.

You can create this from the aircraft power with a small circuit made up of a few resistors, a capacitor, and a small voltage regulator. You probably want a 78L05 regulator. This is a three pin device that looks like a plastic transistor. A voltage divider would be a good idea to reduce your aircraft power (11 to 14 volts?) down to around 7 or 8 volts so the regulator doesn't need to dissipate all the voltage. The capacitor goes on the 5V output of the regulator to keep it low on noise. This is the price you pay for using a digital display. You still need to deal with the issue of presenting the display with an input signal that will make the display show what you want. Rather than a simple display, you really want a voltmeter. I don't know if that is what you have identified. good luck, Paul Camas, WA On 7/15/2011 6:06 PM, Ed D'Antoni wrote: > How about putting a 3 or 6 Volt lithium AA battery in series with the > meter.
