Hand powered USB charger from hacked IKEA flashlight


Werner sends this handy hack he found at IKEAHackers. Giovanni Gentile devised this simple hack which mods an IKEA Ljusa hand powered flashlight into a USB charger. “The procedure was simple, it was enough to eliminate some resistors and use a capacitor sufficient to handle the charge given by the Ljusa’s dynamo. I set the output voltage to 5 volts, and I installed a USB socket. It only remained to modify the body of the torch. Then I printed the bottom of Lyusa filament transparent leaving only the space for the female USB plug.”
