Subject: RE: Chloroplast-o-mania!
Well it was a clear case of parallel evolution I send mine just as I
received yours. Difference? Not much to look at but you may be surprised
they are based on completely different principles (remember small changes,
big effects). In the Chloroplast Thingy, the motor driver with the most
light turns ON and in the PhotoChlor the driver with the most light turns
off! Notice that in your design the PDs are facing the right way ie as PD
with leakage current proportional to light level. In my design they are
upside down ie as small solarcells generating voltage and current.
