Wave Bubble Cellphone Jammer

[MAKE Blog](http://www.makezine.com/blog/archive/2006/12/wave_bubble_ope.html) pointed me to this extremely cool project called a Wave Bubble. Essentially, this device is a portable, battery-powered radio frequency jammer, that will effectively disable cellphone and other RF communication (RFID, GPS, WiFi) within about a 2-meter radius of the user.

The design of the Wave Bubble comes from an MIT EE/CS masters thesis entitled “[Social Defense Mechanisms: Tools for Reclaiming our Personal Space](http://www.ladyada.net/pub/research.html),” in which the author describes the tradition of designing and using electronic devices as social commentary, known as “Design Noir.”

In addition to providing a detailed description and circuit diagrams for builing the Wave Bubble, the thesis is also rife with intelligent commentary on the psycho-social implications of using electronic products and is quite an enjoyable read.

From the thesis:
>Manufacture and use of Wave Bubble is not exempt from FCC regulations. Anyone who decides to build and use it is performing an act of civil disobedience.

I love it! More information and some great photos are available at [ladyada.net](http://www.ladyada.net/make/wavebubble/index.html).
