Anyone have any resources for building one of these singled-transistor tin can radios? I can imagine an article in an old popular science.

They are quite simple, but there isn't much AM transmission any more so you wouldn't have much to receive unless you also build a transmitter.

This one works with shortwave.

This is a simple transmitter.
