Abstract: A device is provided that responds in real time, as well as in a rhythmic fashion, through amplification and processing of an audio signal. The device also will change in intensity. The electronics work off of three DC power supplies derived from a single AC source. The DC power supplies supply DC sources to the lamp voltage, audio amplifier and darlington network. The circuit takes a line (low) level signal into a capacitively coupled audio amplifier IC. The amplified output is then fed through an isolation transformer into a full-wave bridge rectifier to become a pulsed DC to drive the darlington network. The darlington network, used for voltage gain, drives the bases of the lamp driver transistors which are staggered respectively, through diodes to produce the visual effect. The circuit is not limited to driving lamps of any particular wattage or to the housing of the visual display.
