If you've got a professor, a co-worker, or sibling that you really, really hate, this Annoy-a-tron is the perfect thing to drive them up the wall. The small-ish gadget fits discretely under desks, in bags, or in closets and lets out a short beep in 2 to 8 minute intervals.
We had a cellphone run low on battery and beep every few minutes, and since we have about 57 cellphones here you can imagine how hard it was to identify the source. This is that idea taken a step further—just enough to drive someone batsh*t insane.
