• Aerodynamic tail makes Geo Metro even cooler
[MetroMPG], an environmentally friendly car enthusiast from Ontario, added a tail to his car to increase gas mileage. This 1998 Pontiac Firefly is a sibling of the cheap and popular Geo Metro. He had already done some work to cover a portion of the rear wheel wells to reduce drag. Using cardboard, duct tape, and [...]
• You’re not seeing double: RGB Christmas trees
[mrpackethead], created this monster of a tree.  As shown in the video, it’s capable of showing animations, patterns, and potentially video. The 6m tall creation is studded with 2000 waterproof RGB LED modules. Software for the tree was written in Apple’s own Quartz Composer and integrated into Madrix, a piece of software designed with the purpose of controlling LEDs. [...]

• Missile Command on iPhone with real missiles
[Jeff] and his team completed this iPhone controlled rocket launcher as part of their final project at Georgia Tech. Two servos provide the rotation referenced by an onboard electronic compass, and elevation control for launch. These are interfaced with an eBox 2300 using a few Phidgets boards.
Check out the launch video below. It’s too bad [...]
• Spreading christmas cheer w/ auto parts
The folks over at [Soup], a British marketing agency, thought up this cool project. It’s a set of handbells hooked up to an Arduino, actuated by central locking motors found in car doors. By the look of some pictures, there was also a Lego version. Songs written by users (through the online interface) are placed in the que [...]

Taco Bell has a coupon for a free Fresco Taco. I haven’t personally tried them yet myself, but they’re probably not bad. Be sure to get fire sauce!

• Reverse engineering off-brand media players
[Marcan] picked up this device on the cheap and is working to reverse engineer the controller. This media player is an off-brand Chinese model that can be had for the low-low price of $33.97 with free shipping. That’s worth it just to scavenge the parts for other projects, but the challenge here is to hack [...]
• Laser harp
[Jared] had a bunch of lasers left over from a previous project that he put to use by producing this laser harp. The look of it reminds us of a very small Koto or perhaps an Autoharp (although the chords can’t be changed on this model).
We’re so glad that [Jared] spent the time to produce [...]

• Terminate RFID tags
This gun hunts only RFID tags.[mnt], who brought us laser gesture control, built this RFID Zapper but included so much more. Any good weapon has to sound mean, a feat he’s accomplished by incorporating an MP3 player into the rifle. The coil that zaps the RFID tag is powered by a photo-flash unit, but for [...]
• Subcycles: Multitouch music controller
Subcycles is a sound controller application that [Christian] is using on the third multitouch display that he built. The screen is a sheet of acrylic in an aluminum frame. The image is rear projected onto an area covered with Digiline dispersion film. As with other projects that use the Community Core Vision package, a PS3 [...]

• Hacking ZigBee chips: CC2430
[Travis Goodspeed] took an in-depth look at the debugging protocols for some ZigBee chips and posted his findings. In particular he’s looking at the CC2430 System-on-chip. These chips have a debugging protocol that is not hard to implement if you know what you’re doing. Certainly his tips make it easier for the rest of us. [...]
• Four generations of motion simulators
We like a good flight simulator but often find the available control schemes lacking. [Roland] not only builds his own controls, but creates full cockpits that add physical motion to the mix. He completed his third generation cockpit last year.  It’s pictured above as well as in video after the break. That design uses a [...]

So when playing Borderlands, I personally have issues with shadows displaying awkwardly and making temporary glitches on the screen or even a box effect (hard to explain…). If shadows cause issues for you as well, then I suggest turning “Dynamic Shadows” off. The shadows will unfortunately disappear, but so will the glitches. As suggested in other posts of mine earlier on, I recommend also installing the most recent Borderlands patch (1.0.1 as of right now) and updating your video card drivers to the most recent version since these drivers not only offer speed improvements and compatibility, but game fixes as well. Have fun playing Borderlands and be sure to check out the Zombie Island DLC (downloadable content). It’s really cool.

• Advent wreath from parts you have on hand
Here’s an advent wreath made from six parts and a paper clip. Powered by a CR2032 3v button cell, the circuit has been free-formed using a paper clip as the conductor. We love the “dead bug” style of construction used with the ATtiny13 microcontroller because it adds an extra level of intrigue for the uninitiated. [...]
• New AVR simulator for Linux
simavr is a software simulator for the AVR line of microcontrollers. You might be asking why anyone would write this sort of thing considering the simulator provided with AVR Studio is a wonderful tool? Well, a lot of folks don’t run Windows and don’t wish to use that development environment even if Wine or [...]

• Bluetooth based Psuedorandom Number Generation
[MS3FGX] has done an interesting study about using Bluetooth adapters as a source for Psuedorandom Number Generation (PRNG). As it turns out, the Bluez package has a function that calls a remote Bluetooth adapter to return a random number. He picked up 10 compatible adapters for about $30 from DealExtreme and set about assembling some [...]
• Peggy2 x2, with video
Being avid fanatics of flashing lights, we always love to see the peggy2 in action. The video above shows another improvement, which is two peggy2 units working together as one. [iservice2000] chained the two together and wrote new code for the display. Using an Arduino to drive it all, he has gotten them to act [...]
