Fine Tuning the LL Astable

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 5, 2022 - Drifted back to fine tuning the Astable Multi-vibrator as a future clock to trigger a flip-flop counter. I could go with a simple relay but I want to give LL a fair chance. Light Logic does not need a square wave but the sharper the rise and fall time the better. Being a pair of caps are charging and discharging and a couple of CdS LDRs are in the mix, there will always be a lead and lag time to deal with.

In a odd way both ends of the caps find there way to + voltage during different stages of the cycle. Yeah, I should try non polarized caps to see how they work..
