Nice, and even timely for me. I am looking at wireless controllers and USB adapters so I can get 4 controllers hooked up to a MythTV system I’ve built. There are tons of PS2 wireless controllers and even PS2-USB adapters. I figure I could one built up for under CAD$30, possibly much cheaper if I can find deals.

Nice little project there, however, not sure about the Li-Ion charging scheme thats in place. As shown it will almost certainly damage the battery and in worst case could cause it to fail spectacularly (i.e. fire/explosion).

You can buy single cell charger chips from companies like maxim that would be a lot more robust, and include safety options like internal overcharge timers and support proper sensed dv/di, trickle and top-off type charging. Might be worth a look. (EE that deals with li-Ion & Li-Poly designs)

Very nice. Though I wish that Nintendo or a third party is going to develop a proper Wii-specific set of wireless NES/SNES controllers eventually.

Could we just make something like this to use on my original NES?

#2 (I’ve always wanted to call some one that) The ipod battery apparently has regulating circuitry built in

#5, the battery will only contain the “protection” circuitry, which *should* prevent anything catastrophic from happening. I personally would not count on it to withstand sustained usage in this fashion. It is only supposed to be there in case anything goes wrong further up. I have also seen cheap Li-Ion packs omit even the basic safety package (typically just a thermal poly-fuse).

If you could build me one of those bad boys I can supply you with the largest ipod batteries available free of charge! cyanideg2@hotmail.com
