Electronic control for solenoid piston engines

[@kholodilov80]

Why don't use four sensors placed near each piston to track their exact positions? It would eliminate start position dependency issue

[@silectronics]

You’re right except that more electronics are needed and each sensor must still be placed correctly so that it does not overlap trigger pulse from other sensors. One sensor is enough and already advances the counter to individual coils per pulse and this also gives plenty of space for each pulse so that false triggering does not occur. Decoupling is not enough in this type of system. I would need to also add one-shot circuits to prevent multiple pulse outputs from sensor due to misalignments if I add more s snots so I think one sensor works just fine.
