I do remember them showing up in various magazine articles, though. One that comes to mind was by Don Lancaster and had the diode stimulated at some audio rate (near 400 Hz IIRC) and in turn stimulating a tuned circuit, useful for aligning AM radios or somesuch. It was amazing in its simplicity. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.
