Ok, so I picked up one of these laser digital tachometers to see if they could indeed be used to measure the speed of these little motors. After placing a small target adapter on the end of the shaft of a Plasma Dash motor, I turn on the juice (2 AA batteries) and tested it out. The thing works like a champ. I just have to align it properly and I get a real-time RPM reading. AWESOME!!!!. Here is just a quick taste of some results for the Plasma Dash under no-load conditions: 20,580 rpm @ 2.56V (old/weak AA's). I measured the no-load current at 1.18A. This is exciting. Now I can quantify any gains made on motor modifications. I will try to measure some other motors and give results. I think Neuro will soon be able to provide the same info with his new o-scope. I just want to say thank you to TypeZero for the great heads-up on this useful little tool.
