Hi all,
Ok I have a old personal handheld fan and a couple of solar cells from a couple of sidewalk lights.
What I would like to do is build a solar charging circut to run the fan and charge the 2 1.2 Ni-cads to charge and run the fan. I'd like to have a diode in there so the batteries dont discharge, an led to show if the battery is fully charged and a switch to turn off the fan. On top of that im trying to just use resistors diodes n such from my junk drawer. I'm gunna use the whole thing on a food dehidrator. I made a scematic for it but would love anyones input!, thanks to all...
