Things to remember if duplicating Light Logic

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

Just some things to think about if anyone wishes to duplicate Light Logic.

1 - There is a wide low end resistance value range with CdS photo cells so try to test and match the cells used.

2 - Stray light will kill the Light Logic effect faster than anything else.  Light shielding around the Led/Ldr pair IS required.

3 - Operating voltage is very critical and selection of support resistors is somewhat trial and error.

Light Logic in its current development is still very experimental and requires a lot of hands on adjustments.
