here is disco lamp circuit. this circuit using 220 of voltage to operated. One interesting application is to control your disco lighting automatically by the musical sound from high power amplifier, when the music signal is dominating the sound space. The potentiometer shown in the schematic diagram is used to adjust the gain of the pre-amplification. You can use either moving coil microphone or condenser microphone for this circuit. Make sure the electrolytic capacitor is rated for 16 volt or more. You can adjust this potentiometer to get a proper sound level where the relay would be activated.
