Abstract
A disco lamp controller for a coin-operated phonograph in which a signal derived from the audio amplifier signal of the phonograph is applied to the trigger input of an astable multivibrator the output of which is applied to a register the outputs of which cause lamps sequentially to light in time to the beat of the music being played. In the absence of the audio signal the lamps light at a constant frequency.
