Not, Nand and Nor - All in a nut shell

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

Light Logic

By Mark Nesselhaus aka Dr. Cockroach - October 28, 2018

A demonstration to prove out that diode resistor logic, DRL, can perform inverting Not, Nand and Nor logic functions.

Using a LED and a CdS LDR to form inverting logic gates. The entire Boolean logic set can be handled entirely by resistors and diodes.

I know that all this has been covered elsewhere in these logs but I wanted to get the basics on one page.

I still believe you can save some resistors and diodes :-P

Are you sure? yes | no

Well, the resistor to the LDR can be removed if you do not need TTL compatible output and only need to rely on a hard ground as zero :-) That's how IO functioned :-)
