Dead Batteries for 5V USB Charger PUBLIC The goal of this project is to make an efficient and cost effective usage of dead AA alkaline batteries. Eventually this will expand into two circuits to switch between: A) step down to 5V while... by klappy | updated May 22, 2012 aa   batteries   charger   usb
