Seriously, what you need is a transistor, a couple resistors, a relay, and a 9v battery (or whatever.) the transister boosts the 1.5v signal to drive the relay, and viola!, you have power. I havn't done electic stuff in a couple years, so I can't tell you the values, but you should get every thing you need fron "Intro to electronic circuits" or its equivelent ($5 from radio shack). -- :alex. alex@umbc3.umd.edu

I'd agree that you want to use at least a transistor; I don't know what over-driving the power source of the LED with a coil would do to the 3b1 without seeing the schematic, but I hate empirical experiments, myself... -- Dave Ihnat ihnp4!homebru!ignatz || ihnp4!chinet!ignatz (w) (312) 882-4673
