Fresh hacks every day
[Thierry Legault] doesn’t just look up at the stars, the uses a motorized telescope base of his own making to track and photograph secret objects orbiting the earth. What do we mean by ‘secret objects’? Spy stuff, of course.
Last month he captured some video of the X-37B, an unmanned and secretive reusable spacecraft (read: spy shuttle) which … Read the rest
Since 2007, [Adam Kemp] has been leading a team of students from Thomas Jefferson High School, guiding them through the process of designing and building a small satellite that NASA selected for launch early next year.
The CubeSat, officially named TJ³Sat, uses commercial, off-the-shelf components for nearly all its systems. The team ran into a problem interfacing the FM430 Flight … Read the rest
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. … Read the rest
[Tommy Gober] built this Yagi-Uda antenna that has some handy design features. The boom is a piece of conduit with holes drilled in the appropriate places. The elements are aluminum arrow shafts; a good choice because they’re straight, relatively inexpensive, and they have #8-32 screw threads in one end. He used some threaded rod to connect both sides of the … Read the rest
This project provides an opportunity to conduct near space experiments. The flight computer, BalloonSat Extreme, is controlled by a BASIC Stamp 2pe. The complete BOM with PCB artwork is provided. There is enough hardware to control cameras, servos, a Gps, and five digital I/O. The computer is also equipped with a 12 bit ADC to log experiment results. The … Read the rest
Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a Natural Light beer cantenna, pictured in the upper left. His approach used three beer cans, a paper towel holder, and a shower curtain rod. On the tipline, he noted a signal … Read the rest
Wired recently posted an article and video detailing our friend [Chris Tarnovsky]‘s process for hacking smart cards. In the video, [Chris] shows how he strips away physical components of the chips inside the smartcards using various gadgets and chemicals.
The first step is to remove the chip from its plastic frame. After soaking it in acid for about 10 minutes, … Read the rest
