RadioShack Color Organ Electronics Learning Kit

Love lights and music? The Color Organ is a great way to learn about audio electronics. This kit consists of four major circuit blocks: an amplifier stage, a virtual ground circuit, 3 filter circuits for bass, mid, and treble frequencies, and a comparator circuit to measure signal magnitude. To build this kit, you will need the following items: Soldering iron, solder, a 12-volt DC adapter (use RadioShack Adaptaplug "L" if using a RadioShack Universal Power Supply), and wire cutters.
