I'm trying to figure out a way to make a simple and low cost device to help balance RC brushless motors.
While I'd be open to other suggestions, this is the idea that I had in mind that seems the simplest.
I could attach the motor to a loosely mounted motor mount that has an accelerometer (or some other sensor) attached. It could monitor the values of that sensor, and each time one particular axis is at its peak value, it could strobe an LED light. Should work like a timing light, each time the heavy part of the motor comes around, the light strobes so it basically freezes motion, showing exactly where the heavy side is. Allowing you to make adjustments until the motor is in balance.
My biggest holdback is trying to figure out what sort of accelerometer, or other low cost sensor will function quickly and accurately enough to work.
Anyone have any suggestions what sensor to use, or some other general pieces of advice towards making this project?
