Look, a dead bug

A project log for Light Logic

Using a Led and CdS LDR to form inverting Photonic logic gates. The entire boolean logic set handled by resistors and diodes! Who'd'a thunk

Three more little bugs on the way.

Really indicates the size reduction.



Tried to make the 2 input Nand as small as my fat fingers would allow and this is what I came up with...... Measures about 3/4 x 1/2 inch and about 1/2 inch tall.

I have a few SMD Leds to mess around with. The CdS is glued directly onto the Led. The PCB is what the led came mounted on. The Led and CdS were scavenged from a night light.
