so a small hobby of mine has taught me a great deal of things about low voltage electronics. just wanted to know if you guys would be interested in a few items i could show how to make. prepping for things like this can be costly when you buy certain electronics and some can be cheaply made from items you can get at radio shack. one i was thinking would be great would be a solar trickle charger, which is what i would start with. could charge AA and AAA batteries and up to automotive batteries too, though that would require a bit more work. if you guys are interested i can put up a tutorial as well as other things by request. im no expert but i know a great deal about making these circuits and how to make them reliable. yes i realize you can get things like this with a quick google search but having a group of people talking about it will give more people good ideas. also i would present it in a way that would show your options on how to arrange them for different enclosures.
