This little device is designed to do one thing, and one thing only. Annoy the hell out of whoever’s computer you stick it in. Sadly it probably wouldn’t go unnoticed on say a laptop, but on the back of a desktop, priceless.
The time interval ranges from 30 seconds to 8 minutes and it sends the scan code for Caps Lock at random intervals between those times. So every once in a while their caps lock will just kick in.
Now, for a computer savvy user, this might not last long as they’d look for the source of the problem, and probably find it after a few minutes. However the person in the cubicle next to you, or the mean secretary at work, well, they might not be able to find this little contraption, and even if IT searched for a virus it would never find one, so it could go on, undetected, for quite some time. The best part, is its apparently quite affordable to make.
