Okay, now I'm mostly convinced that my C in Physics 3 was well-deserved or possibly optimistic (okay, honestly, I knew that at the time) and/or I've forgotten basically everything in the intervening decade.
This is close in design to the first radio receivers developed, but the inductors are gone and replaced with other components, which makes sense in the context of producing a feedback loop rather than decoding a signal but I lack the training to convert this to a sensible diagram. Specifically, I'm not understanding what keeps the current across the LEDs from simply oscillating as driven by the 1Hz circuit (while damping it into not doing much of anything), which I take as a sign mostly of my failure to remember even basic circuitry. I should re-study this some time.
