I have humble answer to your problem, but I am afraid it contains two
transistors and one resistor for each detector.

I'm tryly sorry for the attachment, I know many of the PICsters don't aprove
of it, but sending the picture of the circuit is the only way I see to give
away this information.

Hope it is of any help, and PLEASE give me feedback if I have completely
screwed this one up, misunderstood something and so. :-) Please be
indulgent, I am only a student yet... :-))
