Sure,
Here is what I have been using since january.
2N3904 or 2N2222 transistor
Tor-23 toroid from allelectronics or Med 5/$1 electronicgoldmine.
1k pot.
battery holder
1.2v NiMH battery
Magwire for secondary
tel. wire cat-5 for JT primary

go to makezine as I told sm0ky2 for general how-to or read my instrux to him on the datalogging page, I think.

Well if there is a self charging unit please do include me in would make an excellent night light...

Or maybe the manufacture of lite brite may want to create a unit with your device there are tons of applications oled tvs that run forever off of batteries muahahaha ok lol just joking there but anyhow I don't see where to go with this other then night lights which is good enough for me.

What is the max time anyone has ran led lights off of these units to spare me the long route?

lol

funny you say that im just getting to that ... in this thred  lol

my 12v is cargeing still 11.13 its a slow crawl but its going ... i will close the loop on this simple unit .. 

to do this i will use a rechargeable battery as a close looped supply i will step down the 12vdc through a 12 -1.5 adaptor .. drop it in a cap or a battery ........ 

thats a few days away right now as i want it to charge from the dead or almost dead aa`s so far i have put 4 lower voltage  batteries in to this unit i started at 7.1vdc in the 12v so i will make this unit im speeking about able to recharge for the first time from dead batteries ... then it can switch on the transformer lower the volts and feed my coil..
