Hi Ryan

looks like the V+ power supply connection to pin 14 is missing. If not then
make some voltage measurements between ground and the pins with a multimeter
and report the results.

good luck

13117 Fri, 7 Apr 2000 14:54:40 -0400 Wacky ideas floating around "BEAM" "William Cox" Hey all, I had a few ideas I like to toss out.

First: Don't you think I be a good idea to have a hyperbolic reflector
reflect the light onto a solar cell? I mean, I would catch much more light,
and focus it much brighter.

Second: What would happen if you made a cube with one sided glass. (Glass
that is see through on one side and reflective one the other), and faced the
reflective side in. Would the light go in and never come out? Then, you
could suspend a solar cell cube inside the "light" cube.....

Third: About this Aquavore discussion. Water eater. Maybe you could make an
adaptation of the light cube design, and have the water come into it, heat
up to 212+ degrees, then the steam would be forced out of the bot and propel
it forward.....

Four: Couldn't you just use a comparator in place of the 1381????

Thoughts that I want an opinion on.....
-William
