Here is a simple circuit to control 110VAC things such as Christmas Lights with low voltage audio. Be careful, high voltage AC can kill you.
“The basic Idea was to have Christmas lights flash with the music. In my design I use an ordinary amplified computer speaker, a diode bridge, and a ‘CRYDOM’ SSR (Solid State Relay). In order to increase the time that the lights were on as well as protect the SSR I used a Diode Bridge to rectify the signal from the amplifier circuit.”

If you just need one you could go to Radio Shack

What was done differently with this project? Individually Controlled Stereo Channels. What difference does this make?
