solid state selectable latching circuit

This is a quick video demonstrating the design of selectable latching using all solid state components.



I got the idea for this design, after watching another utube channel "philomech", he did an excellent tutorial on the design and build of a system called selectable latching, he designed and built his on the concepts of using mechanical relays configured to latch, then made three of them to configure a random selectability in latching and unlatching them.

I wanted to see if I could use that same concept of selectability in latching , but doing it all with solid state discrete components. I chose to make the latches from SCR's.

enjoy...
