XOR and XNOR simple as ever

A project log for LIGHT LOGIC - HIC SVNT DRACONES

Using a LED/LDR pair to form inverting Photonic logic gates. The entire Boolean logic set handled by resistors and diodes! Who'd'a thunk

I now have, thanks to @Starhawk for the nudge, managed to create A XOR and XNOR gate that uses just a single Light Logic switch. I no longer need to combine other gates for these logic functions. Logic highs are 4 volts or higher and the low levels are less than 0.5 Volts. Good enough to be used with the rest of the Light Logic family.

That is the simplest XOR I think I've ever seen.  Congrats, good job!!
