VGA Hardware Screen Blanker

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. This device is totally software and O/S independent. The ONLY screen blanker that can be guaranteed to work !.

As far as I am aware this is the only add-on hardware based screen saver that does not require connection to the video cable, I also think it's the simplest design in existence!
