Light Logic 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

Second and more traditional circuit being tested.

Again, the video does not show very well that the clock rate is stable.

Just wired up a second astable to make sure the first was not a fluke.

Component level schematic of the final astable circuit.

Led's D1, D2 and resistor R3 are not in this tested circuit.


Below is the first version that was a bit messy.

First test using Light Logic Not gates wired up as a astable multivibrator. Poor video capture but the flash rate is indeed constant.
