Sequencer / Ring Counter

A project log for LLTP - Light Logic Transistorless Processor

My attempt to create a CPU/MCU without transistors or relays

I have decided to clean up and use the Ring Counter I designed last year and use it as the Sequencer for the LLTP.

This is the circuit for the initial 3 step Ring Counter. Just add extra steps in odd numbers and this circuit was expanded to the seven steps seen in the video. In the video there is a momentary switch wired off the board. This is used to start the cell reaction. In other circuits I have made, this switch was not needed as the sequencer self started. If the parts are closely matched then the switch is needed but if one cell has actual values that are a little off then the circuit tends to self start on that cell.
