Sounds cool to me! I think it would work very well. I would probably opt for
the head to track the sun since it is the brightest source. Very interesting
idea.
See ya,

7701 Mon, 15 Nov 1999 14:01:31 -0800 (PST) [alt-beam] photopopper circuit revision??? beam@sgiblab.sgi.com Evan Dudzik one thing I don't like about making a photopopper is
the DUAL SE's that have to be freeformed. my question
is, why not use one SE and just have a simple circuit
that would allow the thing to decide which motor to
use with the photodiodes? I would try it, but I have
tried to do things like this that compare the two
inputs (from photodiodes), but they never worked. oh
well... maybe someone can help me out here?

Richard.C is makeing something like this with a Cholroplast, at least
that's what I thought he said, correct me if i'm wrong

Hi Evan,
Seems to me someone did that already. Richard Caudle maybe. Don't remember.
Don't remember how well it worked either.
See ya,
