VGA Hardware Screen Blanker

Posted on Jan 19, 2013

This design was published in the June 1994 issue of Electronics Australia, and has proven extremely popular. The kit was sold by Jaycar Electronics, but has since been discontinued. It is a simple device that connects between your keyboard and VGA card feature connector, and will blank (or blink) the screen after a certain amount of non-keyboard activity.
