Color Organ - I have had many requests for this circuit. It was a very popular unit years ago. The basic
idea of the project is to make different colored bulbs light at different frequencies of music. The circuit
connects to the speaker outputs of your stereo. . . . [Circuit Design by Randy Linscott]
Color Organ - PIC Project This unit uses a PIC16F84 with an 8 bit A/D. The signal from both stereo
channels is combined and digitized. Each of 5 frequency bands is processed using a 16 point FFT. Then the
level of each channel is output as PWM (pulse width modulation) to a set of solid state relays. . . [Luhan Monat

Color Organ Light - This circuit works REALLY well. Notice how it will fire even in complete silence. This
provides a sort of automatic gain control. . . . [Reverse engineered schematic by Stepan Novotill]
Colour (Sound) Organ - Anyone who has been to a night club, concert or school dance has probobly seen a colour
organ. Colour organs cause lights to blink and flash to music from your TV, stereo, guitar and even your own
voice. The colour organ presented here needs no connection to the sound source, it picks up sound from its built
in microphone. . . . [Circuit designed by Aaron Cake]
Colour Sensor - Colour sensor is an interesting project for hobbyists. The circuit can sense eight colours,
i. e. blue, green and red (primary colours) ; magenta, yellow and cyan (secondary colours) ; and black and white.
The circuit is based on the fundamentals of optics and digital electronics. The object whose colour is required
to be detected should be placed in front of the system. The light rays reflected from the object will fall on the
three convex lenses which are fixed in front of the three LDRs. The convex lenses are used to converge light
rays. This helps to increase the sensitivity of. . .

Simple Color Organ - A simple, satisfactory Color Organ can be built with a handful of cheap components. This
design features: no mains supply transformer, built-in microphone and three widely adjustable frequency bands
obtained by means of very simple, passive filters for Bass, Middle and Treble. . . [Flavio Dellepiane's web

Simple Colour Organ - This is a simple, one lamp colour organ. It is far less complicated then the Three Channel
Colour Organ. It is simply a lamp controlled by an SCR. It can be built in a few minutes, and combined with other
circuits to make some pretty neat effects. . . . [Design by Aaron Cake]

Transistor Organ - This simple circuit can provide hours of enjoyment as you learn tunes, play duets or just
make some really weird sounds by pushing all the buttons at once. You have probably seen this circuit before, it
is fairly common. I have seen it in several. . . [Design by Aaron Cake] |
