Wait...all
matter resists current, and all matter can be forced to
emit light, so any item is a 'Light-emmitting resistor'.
One of the early April 1 issues of BYTE (1975? More likely 1976)
has the specs for a "noise emitting diode". If I remember the
definition: "When connected across high voltage, makes a large
noise (once)."
When did LED's begin wandering out of the solid state physics labs
and into commercial products? I remember individual LED's in the
very early 70's, and by the mid-70's they were everywhere in the
form of 7-segment displays.
Is there some landmark "first commercial use" of the classic T1-3/4
individual LED package that's so common today? Were there early
LED packages that just completely disappeared?
