Manekinen from Poland send in some of his interesting projects. If you are wanting to play a great computer prank on someone this Automatic Caps Lock Circuit is sure to fit the bill. It automatically "presses" the caps lock button ever now and then! I can just imagine the frustration it would cause in your typical office. I probably hit the caps lock button 3 or 4 times a day by accident, I would think the user would just think they are having an exceptionally bad day for hitting the button. It is based on this circuit by Macetech which has an English description.
