Weekend project for y'all...  
While you are putting up your holiday decorations, head up to the roof
and pull off that old satellite dish....

Perhaps, you can scan your presents instead of the ol' shake-n-guess.

Make Your Own TSA "Naked" Scanner - Hack a Day 

Have you ever wanted to ability to see through objects? Perhaps you have
been looking for something special for your own personal TSA role
playing adventures? Well, [Jeri Ellisworth] has your back. She has
managed to cobble together her own millimeter wave scanner using a
hacked set of Feed Horns (like from a satellite dish) to create the
image. By reversing the power transistor on one of the Feed Horns, one
of the horns is made into a transmitter, while one of the other horns
stays as a receiver. This data is then fed into a FPGA by way of an A2D
converter, where an image is assembled when the scanner is moved over a
surface. X and Y axis tracking is handled by an optical mouse also
controlled by the FPGA, and the whole setup is output to a monitor.

Right now there is no text write up, or any specific details as the hack
will vary by whatever Feed Horn is available. However, the video does a
great job of explaining some of the electrical concepts, as well as some
very useful schematics. Be sure to watch the whole video after the
break, and don't blame us for any health complications, whether the
radiation is ionizing or not.
