Subject: [alt-beam] FLEDs in Sunlight
Newbie’s Here!!!
All joking aside, I am a Newbie and my question is, in all likelihood, a
real dumb one. But I’ll explain first. My son Kyle (nine years old)
constructed this first SYMET as he calls it. Using a FLED Solarengine,
solar panel, a pair 10000 uf Caps, etc. It is the first free form
circuit that he’s put together. Testing all the way! The beard board
circuit worked quite well but then for some reason when he free formed
the circuit and assembled on a CD with a motor glued in the centre,
LightBot One would just sit there doing nothing even in direct sunlight.
After hours of trying to find the problem I remembered reading once that
some LEDs are effected by direct sunlight. Once the FLED was covered
with a little black tape LightBot One came to life. The little brat
nearly jumped out of skin, after six hours of work he was quite excited
to see his first design in operation. So his question, “Why are LEDs
and FLEDs effected by direct sunlight, while some are not, and what is
happening inside the FLED when the light hits it?
Thank You
Dave and Kyle
