I'm currently building a solid state tesla coil **broken link removed**. and I am trying to use a fiber optic cable to control it. (basically I just need a 10-300Hz signal).
I picked up some of the TOSLINK transmitters and recievers from digikey and 50' of cable. It turns out though, the reciever has a minimum operating speed of 0.1 Mb/s (is that a frequency of 100kHz? or would it be 200kHz?)
If I try to run it at the 10-300 Hz, I just get a random 20uS-40 uS pulse.
I tried using a couple of 555 timers and an AND gate, The one timer was set up to run at 400kHz and the other was variable from 30-300. The variable signal was fed through a high pass filter and and'ed with the other signal, so this produced short 400kHz bursts on the reciever. It seems to work pretty good, but I'd like to possibly find something alittle more robust.
Is there a way to use a phase-locked loop or something to get an accurate signal?
