I'm building a PIC data logger that will run from a wall wart. During a power outage I would like it to stay alive for an hour or maybe tw= o.

Thoughts? thanks chuckc --=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 .
