Make Your Own TSA “Naked” Scanner

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 Ellsworth] has your back. She has managed to cobble together her own millimeter centimeter 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.

Notacon call for papers


Notacon has just announced their first round of talk selections. The Cleveland, OH area hacker conference will be celebrating its sixth year April 16th-19th. When we attended this year we saw talks that ranged from circuit bending to the infamous TSA bagcam. Self-taught silicon designer [Jeri Ellsworth] presented on FPGA demoing. [Trixter] covered his demo archiving process. You can find a video archive of this year’s talks here.

We’re really looking forward to the conference. [SigFLUP] is already on the schedule to cover Sega Genesis development. Get your talk in soon though; they’re already handing out space to the knitters.

Add a second internal hard drive to your laptop

[Andrew] sent in something we’ve been considering for our 17 inch Dell. He squeezed a 100GB PATA notebook drive into the spare space in his Compaq laptop. He used a USB interface to provide the connection and added a toggle switch to conserve power when he doesn’t need the drive spun up. The mod would be even nicer if you added a keyboard activation switch like [sprite_tm]’s keyboard light.

Notacon 2008: The TSA Bagcam

[algormor] gave one of the more controversial talks at Notacon. After receiving a few too many inspection slips and destroyed baggage he decided to find out what was going on behind the scenes. First, he purchased a cheap bag from Walmart with a zipable liner. To record the video, he purchased a SwannGUARD MicroDVR. It’s a palm-sized device that records 128×128 15fps video. It comes with a plastic cover that he mounted to the inside of the bag. A hole was cut for the video camera right above the badge holder. Since the camera is motion triggered, he could slide the badge up, covering the hole, to deactivate the camera. He’s taken the bag on at least four trips. So… what did the footage show?
