Finally, a radio frequency jammer you can build at home! This is a project we have been waiting for for a long time. Introducing the Wave Bubble. From the website:

This website details the design and construction Wave Bubble: a self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camoflauging: it is the size of a pack of cigarettes.

No more annoying cell-phone ringers in the movie theaters! The site includes the CAD files for the mainboard, schematics, and the firmware you will need to be your very own frequency pirate. Oh, and if you do build this thing, just remember it’s illegal to use it - so give it a nice spot up on the shelf and wait for the next revolution. [via]
