yeah sorry guys i should have pointed out i was aware i would need some kind of boost circuit, however since i origanaly posted the question i have found a small 4.5v battery that would do the job, however better than that i have been playing with the charger for the wifes electric tooth brush. i would much prefer to do away with the battery and use inductive coupling or whatever its called, i notice you can buy very cheap chargers for nintendo DS that use the same principle so i might get one and have a play with that. i dont need much current or voltage just enough to power small pic and a couple of leds, the leds wont be all on together so i figure if theese things can charge a battery then they can handle a led and small pic
