I have been thinking about the problem, how to measure cheaply torque of Edwin Gray engine, and I have found this handy thing. There are strong electromagnetic waves inside engine. What about to take a piece of this energy by well tunned LC circuit, rectified by fast diode, filtered and stabilized to power microcontroler, which would transfer signal from well positioned tensometer to serial digital pulses for infra LED taken out the shaft axially. Then it does not matter if LED is spinning.
P.S.To measure angle and speed, I think encoders from http://www.eltra.it are suitable.
My dream is to get engine absolute brushlessly!!!
