If you're looking for big, powerful solar panels, for an affordable
price, you can't beat All Electronics 6x6 inch 9 volt @ 60 mA solar
panels for only $5.25 each!
They are great for larger solar robots, and can drive things like
bicores very easily. They are also think, about 1/8 inch or so, and they
are pretty sturdy compared to some types of solar panels.
Now if only I could find a 7x9 inch solar panel for my BEAMac's "screen".

12509 Sat, 25 Mar 2000 11:31:52 -0600 [alt-beam] NPN or PNP? "BEAM list" "Brian Boeckmann"
content-transfer-encoding: quoted-printable
I was wondering if anyone could help me sort my transitors between PNP and =
NPN. They are all labeled differently. =
I have a simple voltage, current, resisitence meter. Thanks for your time.

How about lining the perimeter of the 6"x 6"solar cell "screen" with
calculator and Sunceram cells until you get the proper dimensions? You could
make it aesthetically balanced and have several bonus cells to hook to other
BEAM circuits. Like, spinners, LED flashers, night LED flashers, or to charge
a battery reserve for night use, ...on and on. Another option would be to
make a matt, like a picture frame out of an aesthetically pleasing material.
Just some thoughts.
See ya,
Jim

I'd love to. But my interests lie in building more complex critters. Next is
a 3 motor, then a 5 motor, then a bot with at least 12 motors. I know
problems crop up with that many actuators, but I have to believe that barrier
can be broken. I'm also dabbling with more functional wheeled bots, and
really want to get back to solar power for the short term. These reasons and
building Carbots and Probebots on commissions will keep me to busy to set up
that manufacturing deal in Taiwan :). But, one can dream with unbridled
passion.
See ya,
Jim

there are 8, 2" x 5/8" cells. They look like they're all in series.
