Play TSA: A DIY Body Scanner
A hacker creates her own homemade full-body scanner using a satellite dish horn.
Amid concerns and debates over privacy and security with the full-body scanners implemented by the US Transportation Security Administration, a hacker named Jeri Ellsworth created her own handheld version of a full-body scanner by tweaking a satellite dish horn.
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.
