Success. I put a 7805 with a couple of 1uf caps on and used the 12v supply from the PJ. For Q1 I used a 2N2222 and for Q2 I used a 2N4403. I had to go down to 10ohms for R2 to get the emitter to trigger. The emitter did lock onto the PJs signal once before and I recall they worked a little...
Thank you very much for the quick and detailed response. I will certainly give this circuit a try. This does make more sense to do it this way. I'll have to hit radio shack as I don't seem to have any PNP transistors in my stock and work on it this weekend. I have a 0-10k pot that I can put...
Situation:
I have a 3D projector that has an output jack for external transmitter. The external transmitter needs ~+5v signal that pulses from 0v to 5v ( +1v->+3v seems to trigger it) to keep the glasses in sync with the PJ. The PJ is only outputting a 0-1v signal.
I've built a simple op amp...
