Supercaps are just like any other capacitor, they just have much greater charge density. The trade-offs are that you must give *extreme* care to the specifications. Do not exceed the voltage rating *ever*. These caps can take a huge charge current, so you really need some form of current limiting in your charging circuit. Otherwise they can be charged with any voltage regulated, current limited power supply. -p. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
