I would like to use an arduino to determine how out of balance my airplane propeller is. I've seen a production device that uses an optical sensor and reflective tape to plot this. Can this be done with an arduino, and if so, what would I need to do it?
The optical sensor is not sufficient. It works in conjunction with an accelerometer to measure the actual imbalance. An Arduino should be able to control the two sensors and have the results displayed. Interesting little project. Btw, the reflector will cause an imbalance itself when attached to the propeller; this should be compensated in some way.
