3 Channel-Color Organ

Color Organ (Aaron Cake) - Anyone who has been to a night club, concert or school dance has probably 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.

Color Organ (Luhan Monat ) - 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

Color Organ (Randy Linscott) - 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

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.

Colour (Sound) Organ (Aaron Cake) - Anyone who has been to a night club, concert or school dance has probobly seen a colour organ.

Simple Colour Organ (Aaron Cake)

Transistor Organ (Aaron Cake) - 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....designed by Aaron Cake
