UAV Reigns Down Vengeance Upon Thee

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by building an armed unmanned aerial vehicle. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a wearable display. We’re betting this doesn’t have the range that the 100km UAV did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.

Update: Here is a forum post covering this nugget of awesome. There are just a few details but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.

GSM Cracked

[Karsten Nohl], with a group of security researchers has broken the A5/1 Stream Cipher behind GSM. Their project web site discusses their work and provides slides(pdf) presented at 26C3. A5/1 has had known vulnerabilities for some time now and is scheduled to be phased out for the newer KASUMI or A5/3 block cipher. This should be an interesting time in the cell phone business.

Thanks to [Tyco] and [MashupMark] for pointing us to this story.

Location Tracking Using IR Throwies

[Joe] and his team hacked together some location tracking using IR throwies for their final project. The challenge they undertook was to find a way to track the orientation of a sculpture in the form of a rotating metal cube. The end result dips its toe into the augmented reality pool but the methods are what interest us.

They wanted this to work day or night so contrast would be a major issue if working completely with image manipulation. Having a simple way to pick out the corners of the monotone block would make this process a breeze. They ended up using magnetic throwies that have an infrared LED which can easily be picked up by a webcam no matter what the ambient light issues happen to be.

After the break you can see these guys out in the wild testing the system. We’d like to note the diffusers used in the project. We’re used to seeing ping-pong balls as diffusers but this is the first time we’ve noticed Styrofoam balls being used.

PS3 Wireless Visual Interface

[Technott’s] at it again, this time extending the Playstation 3 with a wireless interface. This handheld isn’t actually a PS3. It provides a wireless connection to your PS3 to receive audio and video, as well as to manage controller data. Think of it as a wirelessly tethered handheld that allows you to play Playstation when your wife is watching the Real Housewives. This is similar in size to his Xbox 360 WVI but the case shape and appearance are a big step up (not that we disliked that one). We’ve embedded a video tour of the device after the break.

Panoramic Scanner Camera

[Photodesaster] put together a panoramic digital camera using a scanner and some miscellaneous parts. You may remember seeing something like this about six months ago and originally about five years back. The parts used here work together nicely. The sensor board from the scanner is mounted to a metal plate along with a 50mm lens. The plate is mounted to a hard drive platter that is turned via belts connected to the original scanner motor. This way, when you tell the computer to scan an image, the lens is rotated to capture the panorama. The use of an 18V tool battery is a nice portability hack for the scanner circuitry.

Judging from this 71MP image he has achieved some remarkable results.

[Thanks Stefan]

Ikea Dioder Hack

[Joseph] wrote in to tell us about his Ikea Dioder hack. The Dioder is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an ambilight clone shouldn’t be too difficult.

He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.

Composite Video Output From Chumby

[bunnie] posted this pretty slick way of getting composite video out of a Chumby. The Chumby is an open source connectivity device that has already seen some decent hacking. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.
