3 Channel Color Organ for a Car -  An Active Filter Design. . . .  [G.L. Chemelec, designer]

 

3 Channel-Color Organ -  An old ideabut I've had numerous requests for a good design for this. . .  [G.L. Chemelec]

 

4 Channel CAR Color Organ -  FOUR Channels. , All Channels are Active Band Pass Filters. . . .  [G.L. Chemelec, designer]

 

4 Channel HOME Color Organ -  FOUR Channels. , All Channels are Active Band Pass Filters. . . .  [G.L. Chemelec, designer]

 

4 Channel, 12 Volt Color Organ for a car -  Back in the 1970's these were popular for use in homes and the colored bulbs were typically place in a box with a sheet of "rippled/bubbled" Plastic in front to break up the light patterns. Some units gave very impressive light patterns. . . .  [G.L. Chemelec]

Color 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]

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 - Mesa Arizona]

 

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. . . 

 

Common HOT 3 Channel Color Organ for a Car -  An Active Filter Design. . . .  [G.L. Chemelec, designer]

 

Four Channel CAR Color Organ -  FOUR Channels. , All Channels are Active Band Pass Filters. . . .  [G.L. Chemelec, designer]

 

Four Channel HOME Color Organ -  FOUR Channels. , All Channels are Active Band Pass Filters. . . .  [G.L. Chemelec, designer]

 

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 site]

 

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]

 

Three Channel Color Organ for a Car -  An Active Filter Design. . . .  [G.L. Chemelec, designer]

 

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]
