Check out this video from last August’s CCC Camp, which describes using a Universal Software Radio Perhiperal (USRP) to record GSM messages, and then using an FPGA to defeat the A5/1 encryption that’s used to secure an encrypted GSM channel in the span of a couple weeks. By spending a couple months to precompute a […]
Inventgeek has a slick DIY heatsink project. It’s completely silent, unlike the traditional CPU fan. With a $24 ion generator and a few items that you can pick up at the hardware store, the device is able to generate an ionic wind that pulls air through a traditional heatsink. The total cost is under $60, […]
Here’s another fun real-time Google Maps mashup, inspired by flickrvision and twittervision. WikiPediaVision displays recent anonymous edits to WikiPedia, showing you the article being edited, and where on the globe the edit came from. It’s a nice way to passively graze interesting topics that someone else just got done thinking about. Why are these simple […]
Catch this article over at ha.ckers.org regarding an easy way to bypass most anonymizing proxies (such as Tor) and figure out the true origin IP of a web surfer. Plugins such as Java or Flash can be written to make a socket call back to the server. Since the plugin isn’t making a normal HTTP […]
David writes: Bernard shows us how to use an use an accelerometer as a mouse. This project uses a MEMS X/Y accelerometer, a PIC microcontroller and a old mouse. He also describes a trick for powering the new mouse with the unused RS232 serial control lines. This is a great idea. My optical mouse is […]
FlockBots, created back in 2005, were the product of the Evolutionary Computation Laboratory at George Mason University. The concept was to create an open-hardware reference platform for small, sub $800 robots that could be used in education and swarm research. I was noticing this afternoon that the project’s wiki doesn’t seem like it’s been updated […]
