The Annoy-a-Tron 2.0 is a cool little, and I mean tiny, gadget whose sole purpose, as you may guess from the title, is to annoy the hell out of people.

You simply set the device to emit one of six outrageously irritating noises at your chosen volume, then hide it somewhere and watch your school/office mates get more and more annoyed before they head off and search for the offending Cricket chirping, Doorbell, Grating Electronic noise, Electronic Beep, 15kHz Teen Buzz (only younger people can hear it, old biddies lose the ability to hear high frequency sounds), 12 kHz Electronic Noise or a combination of all six.

This inexpensive device is magnetic, making it ideal for attaching to desk legs, filing cabinets, behind radiators and fridges etc.

Personally I’ve been laughing all afternoon since I managed to get it into the air conditioning with the high volume Cricket chirping.
