			<content:encoded><![CDATA[<p><a href="http://www.makezine.com/blog/archive/2006/12/wave_bubble_ope.html">MAKE Blog</a> 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.</p>

<p>The design of the Wave Bubble comes from an MIT EE/CS masters thesis entitled &#8220;<a href="http://www.ladyada.net/pub/research.html">Social Defense Mechanisms: Tools for Reclaiming our Personal Space</a>,&#8221; in which the author describes the tradition of designing and using electronic devices as social commentary, known as &#8220;Design Noir.&#8221;</p>

<p>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.</p>

<p>From the thesis:</p>

<blockquote>
  <p>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.</p>
</blockquote>

<p>I love it!  More information and some great photos are available at <a href="http://www.ladyada.net/make/wavebubble/index.html">ladyada.net</a>.</p>
