PTM: I bored and clued a small magnet to the flywheel and read it with a
self made coil. There was a 4xOP-AMP to get the pulse out for a normal
cheap tachometer from a car. The same tacho was used to measure the water
lewel in the water tank so there was a switch. The face of the tachometer
I made myself, because the frequency from the flywheel is twice too high.
My friend took the pulse out from AC generator.
