Stealth USB CapsLocker Annoys its Victims (Not Late April's Fools)

You have to admit, there is little in this world that gives you the satisfaction of a do-it-yourself project. Doing it for April Fool's day… even better. If you're looking to prank a computer user, what better way to do it than a discrete USB device that randomly sends the caps lock scan code? OK, yeah, there are tons of other options but this one will leave them screaming. The Stealth USB CapsLocker is tiny enough to go unnoticed, especially when surrounded by other cables and devices.

This is sure to be enough to cause temporary insanity, as the user's caps lock is turned on or off at random intervals between 30 seconds and 8 minutes. Perhaps what is best about this device is how incredibly simple and cheap it is to make, requiring just a tiny bit of soldering and a few parts.
