Hi Everyone,
I am trying to do something on a quite small scale here with:
* 2, 2volt, 500milli amp solar panels
* 2 Nickel Metal Hydride (spelling?) AA batteries
* A couple of super bright 5mm LED's, however many I can run off 2 AA's.
* A Light Sensing Diode
* A Schottky Diode
* An ON/OFF switch
Pretty much is a portable LED solar light.
What I am trying to do is hook up the 2 little solar panels in the best format (parallel or series?) posible to charge my AA batteries and then when I feel like it (probably at night) I can flick my little circuit on and have a little bit of light from my LED's. Could be handy when I go out and come home and it's dark and I want to find a light switch or something.
I will try to set the whole thing up in a little plastic box, and I was going to make the solar panels hang off it on adjustable storks, so that where ever the box is placed the storks could be moved to set the solar panels to face the sun. I imagine the storks, would be kind of like swivelley car areial things. A straight peice of metal rod with a swivel ball joint on the end.
I have yet to find a good circuit diagram or even any material that I can use to learn more about circuit's so I can build my own circuit. Any tips help with how to set it all up in the best way would be very appreciated.
Thanks
Simon
