    Oh gods, I'm gonna have to find resources to study up about resistor-transistor, diode-transistor, and transistor-transistor logic, if I want to be able to implement the round-robin circuit for the Horologium Keplerus using discrete transistors. >.>;;

    I guess RFC for links to resources if anybody has useful links that can cut through the less than optimal search engine algorithms that almost only return SEO'd blogs that have no meaningful information?

    This circuit would be so much easier to implement if I would just let myself use J/K flip-flops, but:

    1. the only cheap ones available are duals in 16-pin packages when I only need one per ring node and each ring node is an independent pcb, and

    2. I very explicitly decided that the light at each node MUST be surrounded by a curious cloud of discrete components for the sake of art 😤

    Update!

    @MeiLin gave me the search engine shibboleth I needed to find this web page with a lovely and clever transistor circuit that I can try out!

    It's even simple enough for me to try to breadboard it!

    Edit:
    ... Oh wait this emulated schockley diode circuit requires obscene voltages in order to exceed the avalanche breakdown Vec. I uh... can't use that. I'll need to find other solutions. :x

    At least I now know that what I'm designing is a bunch of giant, wall-mounted, concentric ✨ ring counters ✨ to be implemented using discrete components.

    That's knowledge I can carry forward to more effectively find solutions, and I may have actually already found one I can already use, but alas it must wait until the work day ends.
