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.”
