Starting point of this project is an easy to handle video false color device, sound reactive and also suitable for a DJ. The input signal can be a PAL/NTSC video camera or video player. As output device you can use a flatscreen or a beamer. The Visualist has mainly analog circuits so the effects are in realtime. You need to have some knowledge of electronic circuits, parts and soldering. Success!

  • The block diagram of the sound board shows the selection switch between the built-in microphone and the line input. After that comes the automatic volume control. Third is the filter for bass, mid and high tones. Last are the LED drivers for the Light Dependent Resistors. They control the RGB color saturation in the output video signal.

  • The second picture shows the sound circuit.
