Hi all,
I'm thinking to an "essential" solar-charging system for a prototype of a
"very remote" meteo-station . Average current consumption of the logger with
all sensors is little, about  100-150 uA, so a possible solution can be a
very little solar cell recharging a pack of 3 or 4 NI-CD cells (AA type). I
have tested with a small  (1" x 3") solar cell from a toy and I have
measured about 40 milliamp. out in direct sunlight. I'm not an electronics
expert but I suspect that this current is too high when the cells are full
charged and a regulator will be mandatory (or I'm wrong?).
I have read on PICList a lot of e-mails about a solar-charging system some
days ago, but it seems a bit excessive for my use.
Can anyone suggest me a simple and rugged solution for regulator?

thanks in advance
Marco
