John,

Go to Radio Shack and get their Engineer's Notebook, Integrated Circuit Applications. In it you will find a section on the 555 timer chip. This chip can be used to control a relay, and you will find circuit diagrams showing you how to put the circuit together (a couple of capacitors, a resistor, a couple of diodes, and a relay). You could also try doing a google.com search on the 555 timer and find some circuit diagrams on the web.
