Description

The Colorganic Spectralizer is an audio spectrum analyzer with seven bright 10 mm colored LEDs. Use it as a miniature color organ or just a flashy desktop display thingey. Each LED responds with a brightness that's in proportion to the sound level at a particular frequency. The Colorganic Spectralizer comes complete with an integrated microphone and runs for hundreds of hours on one set of AA batteries.

Applications:

  • Entertainment or game system enhancement
  • Visual telephone ring indicator
  • Visual baby monitor
  • Video game enhancer
  • Visual aid for the deaf

This is a hackable gadget! The design files are published here (see the Resoruces section below), and you can modify the source code and reprogram the device. There's even a Bar Graph LED modification that you can build and add on to make your Colorganic Spectralizer look like a graphic equializer display.

This kit is a beginner level electronics construction project. PTH stands for Plated Through Hole and is the only type of soldering that's needed for this kit; all of the suface mount parts are pre-assembled and tested. The indicator LEDs can be arranged in any color layout that you want. You can use the standard layout, or rearrange the LED colors to any design that you desire. In order to assist you with the color layout design, use the color layout designer tool before assembling the kit. The kit construction instructions can be found in the Resources section below.
