Decided to build a wireless rotor tach.
This is just dead bugged on the wire for now and will be put on a PCB board once the design is complete.
This is a crystal controlled F.M. transmitter, so the frequency is very stable and Yes, I can modulate a crystal in F.M.
A phased lock loop will take too much power to operate.
The transmitter is powered by a generator supplied by the ring gear teeth and a magnetic pickup, just like the pickup you use on the red lion tach.
This will work with a programmable tach like red lion or one that delivers one pulse per rev.
The upper unit will not need power since the rotation of the rotor head powers the transmitter.
It will be smaller than a one-inch square and one half inch tall.
A small F.M. receiver will be hooked to the tach and BINGO wireless rotor tach.
Not bad for a drunk, pot smoking, swamp rat !!
Should be able to market this device with no problem.
Here's a vid to demo and explain
