	One main problem with this circuit is that a standard line-level audio signal from a portable media device or a computer is not loud enough to drive the transistor to light up the LED(s), so I used an old pair of desktop computer speakers (also from the boneyard) to act as an amplifier; so that the amplitude of the audio signal the system received would be loud enough to light the LED(s).

			This is a circuit that flashes an LED or LEDs in time with music. You hook up an audio source to the circuit, and the LED(s) light up brighter when it is louder, and are off when it is quiet. This rave-like effect is achieved through the use of just one transistor.
