I saw a 5.5V 1F capacitor. I wondered if, once charged, something nasty could happen if it's accidentally shorted? I'd prefer to play on the safe side, this device seems scary to me (one whole Farad!). The short-circuit current can be hundreds of amperes, not? Or do they have very high ESR? -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
