I figured hundreds if not thousands of DIYers like me at one time or another built a Solar Powered LED "Thingy" and posted what they did and how they did it. So I Googled, and what do I find, A million sites that want to SELL me solar powered stuff, or TreeHuggers telling me I NEED, no MUST, use solar powered stuff and "where to buy it".
So, here's what I'd like I need to run a 200ma load for 12 hours a day. I'm Florida so sunlight is plentiful. I've got several 5400mAh Lithium Ion battery packs (free), I've got lots of leds. i don't have any solar cells. I can soldier and read schematics. I can usually make things work. All I need is a pointer to some decent ideas.
I know Li-ion batteries need special chargers. I here a lot about "SuperCapcitors" I purchase stuff from Digi-Key and Mouser frequently. I'm not looking to make the most efficient led driver ever invented :) Just something that works..
I'm not to low to simply go buy a toy electric plane and rob it of it's "super capacitor" and goto the cheap chinese dollar store and buy some cheap yard lights to hack apart and make my project out of.
So, any suggestions?
