Divide By 2 Without Transistors

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

January 14, 2022 - One thing I have decided on is that when Light Logic is used in toggle latching circuits I must be more precise in matching the LDRs for their lower resistance with the Leds I am using. Normal combination logic is not generally a problem but with a clocked toggle arrangement any major mismatch leads to problems in latching or holding a latch and I have to be real careful when adjusting the voltage for everything to work the way I want. Ahhh the trials and tribulations of Light Logic.

January 11, 2022 - Making a divide by 2 circuit with Light Logic and a astable oscillator also using vactrols has been quite the challenge. Far from being stable, it is a start and at least proves to me that Light Logic can do it all as long as I do not lose my mind in the process. The main logic is a Nand D Flip Flop along with a few other support gates.
