Just Starting out:
Phase 1 - Collection / Solar
Hitting a few e-waste places and smaller computer shops. I have 1 solid connection for a small e-waste place, and 1 computer store. I'm working on 2 other computer stores.
1.1 - Sorting and charging
Built a 5V power supply from an old ATX PC power supply. added 8 220ohm 1/4 watt resistors and a 12v 10watt light I had kicking around to give me stable voltage on this. added some connectors so I can quickly connect and disconnect things.
Using those ebay charger boards powered by my new power supply, I kept it nice and neat. Next phase of this small project will be hooking up an arduino with DS18B20 under each cell. I'll probably just throw a RED or maybe an LCD that will display max temp so I don't have to come back each time and check if it got hot. I still have toorder those.
Reviving batteries that are more than 1.5v. I charge 4 at a time (match starting voltages) at 62.5mauntil it reaches ~3.0 -3.2volts (depending when I come back to check on it). bump it to 750ma for a while until 3.8-4.0 volts.When I return, I check temperature.Ifgood, Iremove them and put them into a ready for a normal charge bin.
1.2 - Solar requirements
I have a limited space for solar panels, and no south facing roof. they will have to be placed on the ground which I am surrounded by houses.so I need to figure out if there's a maximum output /panel based on location and when the house starts to shade the entire backyard, figure out maxpanels I can reasonably fit without the wife complaining,(thinking 4x 260 watt - have2 now)I'll build my battery to match theoretical capacity needed.
