Do you have the desire to change any audio signal, and transform it into an amazing visual display? This also a simple device, you just plug it into the wall, then insert the ¼” jack, turn it on, and enjoy the pleasure moment.

If you do, then this will keep you busy for a while.

The material you needed:

  • Soldering iron
  • Solder
  • Wire
  • Audio amplifier
  • Multimeter
  • Audio jack
  • Various screwdrivers
  • Alligator clips
  • Sound source
  • DPDT switch
  • Rubber gloves, and
  • Last but not least, a television

For this project, you have an option here; use either the black and white television or Webblevision. Still, you’re better choosing first option, as the Webblevision doesn’t have switchable video mode as Wave Vessel did.

Alert that you must remember here…Don’t even try to touch anything on the board that showed at the above figure. It has enough electricity to give you a fatal shock!

You are advised to put on your glove, before unscrew the television case. Once you’ve opened the Television, you will see four wires (red, orange, yellow and blue in sequence). Two of the wires control the horizontal motion, while the other two control the vertical motion.

Below here are the steps and you needed to follow it carefully:

  1. Firstly, clip and strip all four wires, and then connect them back with alligator clips.
  2. Remove one of the clips and turn on the television.
  3. If the one or both horizontal wires has been disconnected, you will get a vertical line at the TV screen display and otherwise.
  4. You get a dot, if you’ve disconnected one horizontal and vertical wire.
