Super-regen receiver / detector?
(It's not clear whether we're counting only distinct topologies, or the same basic circuit connection adapted to different problems, e.g. a "Darlington electrometer" == or != "Darlington," == or != "Nuclear War detector" ?(*)

I built a battery-powered 2-terminal -1K resistor as an EE project, pretty much like fig 6 there. It was fun to play with.
