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 __ Designed by Luhan Monat, Mesa, AZ

Colour (Sound) 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. __ 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 __

DSP Musicolour Light Show; Pt.2
In last month's first part, we described the circuit operation of the DSP Musicolour. In this instalment, we guide you through the construction. The operation of the firmware and troubleshooting tips will be described next month. In this issue there are also notes and errata for the schematic published last month.___ SiliconChip
DSP Musicolour Light Show; Pt.3
In last month's article, we detailed the construction of the DSP Musicolour. In this month's article, we guide you through the final testing of the DSP Musicolour and give troubleshooting tips. We also explain the operation of the firmware in more detail as well as discussing possible accessories.___ SiliconChip
DSP Musicolour Pt.1
This DSP Musicolour accepts audio input signals and drives coloured lights "in tune" with the music. Its four output channels respond to different audio frequency bands and the brightness of the lights is in direct proportion to the amplitude of the frequency components. A dot-matrix LED menu display is featured on the front panel and this also functions as a spectrum analyser or VU meter.___ SiliconChip
DSP Musicolour Pt.4
With a small and low-cost add-on PC board, the DSP Musicolour can be operated via an infrared remote controlvery handy if you want to use it in hard-to-reach places.___ SiliconChip
Four Channel CAR Color Organ
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. __ Designed by G.L. Chemelec

Simple Circuit 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 __ Contact: Flavio Dellepiane, fladello @ tin.it
