Xbox 360 Wireless Visual Interface

September 13, 2008 by 8 Comments

[jon barber] pointed out another great project on the benheck forums that hasn’t gotten much attention. [techknott] built a wireless video interface for his Xbox 360. Think of it as a sort of video game thin client. It has the form-factor of a portable but doesn’t include the 360’s components. Instead it has a 1.2GHz A/V receiver and the guts of a wireless controller. The specific transmitter was chosen because it wouldn’t interfere with the 2.4GHz controller. The power supply is two 2600mAh batteries running at 7.5V with a built in charging circuit. The draw from the screen is ~500mA. The entire unit is 1 inch thick.

Wifi Robot : A Hacked WRT54GL Rover

August 28, 2008 by 16 Comments

[Jon Bennett] sent us this link to his Wifi Robot. After playing with a Linksys WRT54GL router, he was inspired to build something that would utilize this embedded Linux system. Using a thrift store R/C truck, he built a wireless robot rover. This thing can be controlled over the internet, or by laptop with a range of about 500 meters.

The router has been modified to have 2 Serial ports and a 1GB SD Card. It connects to a micro controller, which could be an Arduino or AVR Butterfly. He has supplied information for both. The truck has been mostly gutted, leaving only the chassis and electronics. He had to beef up some of the truck electronics when they fried under the load. The entire unit is powered by a pair of 7.2 Volt 3800 mAh battery packs. The most important thing on the list though, is the horn. You can honk the horn while you are driving this thing around.

The site supplies tons of information including pictures of his build, videos of it in action, speed tests, schematics, software downloads, and resource links. Great job [Jon].

Burning In The Siftables

August 13, 2008 by 5 Comments


[Curiouslee] put up some pictures of his Siftables burn in. He got them in the mail with all their accessories and decided to make a special box to carry it all. He started with an ArtBin parts box and cut out dividers where necessary to make everything fit nice and tidy.

The Siftables are quite interesting. They are an information interface that is supposed to be more physical and natural. The analogy they use is a container of nuts and bolts can be sifted through quite easily using your hands. They envision us being able to sift through data similarly. They also mention that it could be used as a gestural interface as well.

Defcon 16: Covert Warballooning Flight

August 10, 2008 by 6 Comments


Since last month, when the Defcon warballooning event was announced, [Rick Hill] finished building his rig and even got FAA approval for the flight. Just when everything seemed set, the Riviera Hotel management decided not to allow the takeoff from their property. So, naturally, [Rick] and his team rented a moving truck and covertly inflated the balloon inside. They launched it in an abandoned parking lot and drove through the Vegas strip. They were surprised to find that about one third of the 370 wireless networks they scanned were unencrypted.

Netgear Open Source Router

June 29, 2008 by 10 Comments


Netgear recently launched the WGR614L wireless router targeted specifically at open source firmware enthusiasts. It can use Tomato, DD-WRT, and soon OpenWRT. The core is a 240MHz MIPS processor with 16MB of flash and 4MB of RAM. You’ll probably remember when Linksys decided to dump Linux from their iconic WRT54G line in favor of VxWorks; they released the similarly speced WRT54GL for enthusiasts. Netgear seems to be arriving pretty late in the game, but they’ve set up a community specifically for this router. Time will tell whether community support is enough to make this the router of choice for hackers. We wish someone would release an x86 based router in the same price range just to make porting stupidly simple.

Wireless Arcade Stick

June 25, 2008 by 2 Comments


[astralpancakes] wireless arcade stick project looks like a great place to start if you want a simple project. Well constructed arcade sticks can cost $100+, but with all the MAME cabinet builders, the parts have become easy to acquire. The stick has a rigid wooden case with a metal faceplate. All of the component connections are soldered to the pads of a Logitech wireless controller. [astralpancakes] built this specifically to play Street Fighter III: 3rd Strike.
