I can only second (third? thirtieth?) the preceeding warnings. A friend of
mine, after a high school course in electronics once tried the kind of
recharge proposed here, to his cost. A little knowledge *is* a dangerous
thing. The resultant explosion turned the innocent bits of the plastic
charger-box he'd built into shrapnel. No one was hurt, but it could have
been nasty if someone had been in the room at the time.

Admittedly, the more common result is a loud "pop" and a catastrophic
leakage, but why gamble? I realize that the "designer" of this contraption
said, "The experience was about as life threatening as a squirrel urinating
on my lawn" but I'm thinking "good luck" rather than "good tech".
