[sdiy] My good old VGA oscilloscope plugged to my modular..

[Jean-Pierre Desrochers]

Here is a short video of my 2015 open source VGA Oscilloscope project.
It's made out of a small Microchip PIC micro with the help of some analog comparators circuitry. 
This box produces a vertical line that follows the incoming stereo audio signal connected to it. 
It then drives an external VGA display. 
A choice of 7 different colors can be applied to the vertical line. 
It just needs an old 4:3 VGA screen with a 800x600 resolution.
