Wave Wrapper and LEDs: Question ???

[Toby Paddock]

LEDs do generate juice when exposed to light.
Not very efficient, but pretty fast.
The only time I tried it was to look at the modulation of 
one of those cheap laser tag pistols.
I connected it to a scope and shined the pistol at it.
It did work after I added a load resistor to discharge
the scope input capacitance. I think in general
that they respond best to the same color that 
they emit. So I must have used an I.R. LED (?)

Heading off-topic, I've wondered if shining light
on a neon lamp would lower its trigger voltage.

I like using the word "juice" for the same reason
my high-school electronics teacher hated it:
It's vague.
