RF

After going to one too many movies where the other patrons feel it’s necessary to tell their friends via cell phone about how the movie is going during the movie, I only wish I had the electronic skills necessary to put together my own Wave Bubble, a self-tuning, wide-bandwidth portable RF jammer. It’s the size of a pack of cigarettes, has an effective range of approximately 20 feet, and can jam cell, cordless phone, GPS, WiFi, Bluetooth, and more. Plus, it’s an open source project, so if you’ve got the skills, you can make your own. Jamtastic.
