What is more interesting is the 3 solar cells...

Scroll down to the bottom...

I connected the 3 solar cells in series by using that old trick with the
'convert 2 battery boxes to 18 volts...' thing, and got approx 9 volts coming
out of the end wire.

the issue is that there was only 2 and a half mA (if I used the meter properly),
which isn't nearly enuf to power the RCX.

The batteries are supplying around 30 mA to the RCX, so that means I would need
around 10 sets of these things just to come close--that's 30 solar cells!

Not likely.

So there goes that idea.

Was fun playing with the solar cells though.

It's pretty good. I'l post pics. Built it faster than the backhoe. Still no studded beams (for Steve, just letting ya know) But pretty intricate--4 wheel steering and such. Few little gizmos to add to the overall 'cute factor'. Now I'm going to see (...) (21 years ago, 20-Jun-03, to lugnet.org.ca.rtltoronto)
