You are on the same quest as I grasshopper. I'm using a Duracell 6V -1/2 AA
on Scarlet (Unicore rover) now. It will run forever on this battery but still
needs replacing eventually at $7-9.00 a pop depending on where I buy it. I
saw some 3.5 volt rechargeable in a similar size (size-N, same overall, but
slightly slimmer than a 1/2 AA) in a recent catalogue. I need to look it up
again. I've also been looking at some Lithium button cells that might do the
trick. I'm beginning to get the impression that more complex bots are going
to require a slightly different solar charging system. I'm thinking of
tinkering with tossing the caps and replacing them with rechargeable
batteries fed by a strong solar power plant. I can hook a large solar cell to
scarlet right now and it will run normally under bright sunlight. No solar
engine, no cap, no sleep phase. Why can't a diode and battery pack be hooked
to that cell, or possibly a second of similar size, charging sufficiently to
allow a switch to the batteries in low or no light conditions? That switch
over is as simple as Bob Shannon's phototransistor switching circuit. Or many
other similar ideas using CDS cells. And I have been surfing Zoz's Pockmark
pages as well. Do we really need these solar engines when a strong enough
solar cell will do the trick? Or am I delusional?
See ya,
Jim
