to make the required cell you will need (9 clean empty cans),(9*8inch strips of 10-12 gauge copper wire),(some self tapping screws).
to build
1)wiggle/break the open tab off the cans and force the lid part flat open.
2) strip 3/4 inch insulation off a strip of wire make a loop.use this loop as a screw hole and bend the wire in an "L"shape so one end attaches to a can by screw and the other end of the wire reaches through the drink hole in the can beside it. strip the end of the wire the reaches into the next can this is an electrode plate.
wrap all the cans in newspaper to insulate them from each other.
put all 9 wrapped cans in a shoe box and screw in the electrode "wire" .
once you have the battery built add 3ounces of vinegar and 7 ounces of water to each cell. your battery should make 4.5vdc. though it will drive a LED directly "kinda-dim",we won't use it for that but to charge another battery.
now I suggest a L-ion 3.7-4.2v @ 800-1000 mah rating. from old cellphones.
also to complete the project you will need 2- 4.5v solar cells I got mine from broken garden lights.
so here is the project idea and concept. a (thermo nuclear aluminum depletion reactor).
it depletes aluminum so if you plan to use it long you will want to replace the insulator material with say a plastic cup to catch the (pickle juice) for re-use.
I ran this circuit I made for the last month 12hrs a day, still super bright no noticeable depletion of either cans or copper wire but the alum is expected to deplete.
in short the solar cell do little to charge the battery so does the can battery but though we get all the sun has to harvest, it continues to charge at night from the can battery.
now I am using 3 (9can) cells in parallel at 4.5 volt. now and have all i need to use this light 12 hrs a night and still very bright after a month..Statistics: Posted by iamdenteddisk — Sun Nov 03, 2013 5:56 pm
