Remote Controlled Pill-bot

August 6, 2008 by 12 Comments


The NanoRobotics Lab at Carnegie Mellon University has come up with a medical robot that can be swallowed, and is then able to be controlled from outside the body. The device has small arms with adhesives that can attach to slippery internal surfaces, which has previously proven difficult. Once inside the body, it can be used to view damaged areas, deliver drugs, as well as biopsy questionable tissues, and possibly even be used to cauterize bleeding wounds with a small laser. The device could be stopped, and even reversed to get a better look at areas that may have gone unnoticed otherwise. This would be a major advancement in diagnosing intestinal problems, and could lead to potentially life saving treatments. Did we mention that it has lasers?

Autonomous SWARM At Large

August 6, 2008 by 9 Comments


SWARM has been showing up at a number of places. Until now, the mysterious spheres have been under human control. However, the SWARM has taken the first steps to autonomous control. The SWARM is a kinetic art project consisting of several large self-propelled metallic spheres that interact with each other and their environment. Each orb in the swarm is fitted out with a processor, GPS, accelerometers, and Zigbee wireless communications. The entire project is open source. Slated to appear at the 2008 Burning Man festival, the orbs will use their GPS to wander within a specified area, keeping themselves “in bounds”.

More On GIFAR

August 6, 2008 by 9 Comments


[pdp] provides some perspective on the news regarding the GIFAR attack developed by researchers at NGS Software. As he explains, the idea behind the attack, which basically relies on combining a JAR with other files is not new. Combining JAR/ZIP files with GIF/JPG files will create hybrid files with headers at both the top and bottom of the file and allow them to bypass any image manipulation library as valid files. While tightened security and more stringent file validation practices are advisable, the problem is larger than just a vulnerability in browser security. ZIP is an incredibly generic packing technology used everywhere, from Microsoft files to Open Office documents, and of course, in JAR files. He closes with, “any file format that is based on ZIP, you allow your users to upload on your server, can be used in an attack”

Laptop Containing 33,000 Clear Users Information Stolen

August 6, 2008 by 17 Comments

Security 101: Never put unencrypted sensitive information on a laptop and expect that it’s safe. Especially if you are the TSA. Recently, the TSA announced that a laptop was stolen from San Francisco International Airport containing “pre-enrollment records of approximately 33,000 customers” for the Clear Trusted Traveler Program. For $100 per year, the Clear Program enables travelers to get through airport security faster by showing TSA officers their Clear Registered Traveler Card and going through a special security line. While this program has no doubt saved many people valuable time getting through security, there are about 33,000 people who are now asking the question “Who has my personal information?”

Edit: It looks like the laptop was found, however it is still unclear if the information on the laptop was compromised. In addition to basic personal information (Name, Address, Birthday, etc.), the laptop also contained drivers license, passport, green card information about clear users. You can check out the story here. Credits to [AudioCraz-Z] for the link.

DIY Kidney Machine Saves Girl

August 5, 2008 by 17 Comments


When the tool you need doesn’t exist, you must make one. That’s exactly what [Dr. Malcolm Coulthard] and kidney nurse [Jean Crosier] from Newcastle’s Royal Victoria Infirmary did two years ago.

When a baby too small for the regular dialysis machine (similar to the one pictured above) needed help after her kidneys failed, the kind doctor designed and built a smaller version of the machine in his garage, then used it to save six-pound baby Millie Kelly’s life. Since then the machine has continued to be used in similar emergency situations.

Vista On A PS3

August 5, 2008 by 16 Comments


Apparently you can run pretty much anything on a PS3. [mopx0] has managed to get Vista running on his PS3. He used Qemu 9.0.1 to install Vista on a PC. He says it takes “about a day or so”, after using Vlite to speed it up, so be patient. You then make an image of the install and copy it to your PS3. Don’t worry though, your hard work will be rewarded by a speedy 25 minute boot time when you’re done.

Even though it is extremely slow, to the point of being nearly unusable, its good to see people pushing the boundaries of our hardware’s intended use.

Deogen, Tiny Monitor Tester

August 5, 2008 by 5 Comments


Deogen is a small, self contained device for testing monitors. It was designed back in 2000 to reduce the amount of space and effort required to test monitors in a computer shop. The initial design used an AT90S1200 microcontroller to generate test patterns for the monitors. Being about the size of a portable CD player, it was much easier to take to any monitor and plug in for testing.

Version two of the device, pictured above, is much smaller, being about the width and height of a credit card. The depth is slightly larger than a 9 volt battery. Compared to the last vga test project we ran, this one is tiny. The unit boasts a decent set of features, such as; eight test patterns at four different resolutions, battery or DC power, and small form factor.

The processor of version two is an ATtiny2313 at 20MHz, and controls the H sync and V sync signals directly. The RGB is converted to analog using a resister network. The power circuit is custom made for low power consumption, though they note that a 78L05 equivalent unit could be used in its place.

The plans for the PCB and the software are available from their site. Head on over and check out some pictures of it in action.
