Have you ever wondered what you might look like in one of those TSA airport scanner images? A hacker called Jeri Ellsworth was curious, so she built her own version of a TSA scanner by modifying a satellite dish antenna horn.
By reversing the operation of some key components, the modified LNB three horn array can penetrate a layer of sheetrock to show what's underneath. That it works at all is pretty cool, even if the resolution is pretty poor because the wavelength is quite a bit longer than with the Fed's $150,000 version..
This would be great fun at parties, where you could play a game called what body part are you seeing? Or you could use it to test out that scan proof underwear.
Check out the video where Ellsworth describes how it works.
