Hasta La Gadget!

DIY weaponry gets more lethal with each passing year; where once we were content with a simple foam missile launcher, technology has progressed such that our automated turrets now spew screwdriver bits, airsoft and paintballs. As progress forges ahead, two engineering students at the University of Arkansas have added injury to insult with this four-stage DIY coilgun. Using an Arduino microcontroller to actuate the firing mechanism and steer the monstrous wooden frame, they nimbly control the badass kit with an iDevice over WiFi, and line up targets using a repurposed PlayStation Eye webcam. While we’d of course prefer to have our phone SSH into the gun over 3G, we’re not going to argue with success. We’d like to keep our lungs un-perforated, thank you very much. See it in action after the break.

It’s always been possible to run webOS on a PC using the emulator built into Palm’s SDK, but it turns out that the OS image used for the emulator can actually be installed on an IDE hard drive and booted from — which is exactly what one enterprising member of the PreCentral forums did with his Dell C600 laptop. It’s not too surprising webOS can do this, since it’s built on Linux, but don’t get too excited yet; the OS runs in a funky aspect ratio in a small portion of the screen and the lack of a touchscreen means you’re stuck using the keyboard to navigate. Still, it’s hard not to watch this without visions of webOS running on all manner of HP hardware in the very near future — a tablet, perhaps? Video after the break.

It’s rush hour, and you’re headed due West on your evening commute — the sun burning holes in your eyes. You could flip down a window visor, trading your field of view for visibility. Or, with a prototype shown off at Intel’s 2010 International Science and Engineering Fair, you could simply let the windshield darken on its own. Two San Diego students (both accustomed to copious amounts of sunshine) rigged a Toyota Prius to do just that by stringing up electrochromic panels, which dim when voltage is applied. The trick is figuring out when and where to apply it, because when the sun is shining the panels themselves all receive the same amount of light. So instead of gauging it at the glass, Aaron Schild and Rafael Cosman found that an ultrasonic range finder could track the driver’s position while a VGA webcam measured the light coming through, and darken the sections liable to cause the most eyestrain. We saw a prototype in person, and it most certainly works… albeit slowly. If you’re rearing to roll your own, it seems raw materials are reasonably affordable — Schild told us electrochromic segments cost $0.25 per square inch — but you may not need to DIY. Having won $4,000 in prize money at the Fair, the teens say they intend to commercialize the technology, and envision it natively embedded in window glass in the not-too-distant future. Here’s hoping GM gives them a call. See pics of the Prius below, or check out a video demo of their prototype right after the break.

We think you’re going to be hearing a lot about this one over the next few days… or weeks. A team of researchers at the University of Washington and the University of California San Diego have determined that, with physical access to your car’s ECU, a hacker could “adversarially control a wide range of automotive functions and completely ignore driver input — including disabling the brakes, selectively braking individual wheels on demand, stopping the engine, and so on.” For example, the team was able to connect a computer to a car’s ODB-II port, access that computer wirelessly, and then disable the brakes in the first car while driving down the road in a separate vehicle. The conclusion is that these in-car systems have few if any safeguards in place and, with physical access, nearly anything is possible. The solution, of course, is to prevent physical access. So, if you see a hacker hanging around in your car looking all shady, or a laptop computer sitting in the footwell that totally wasn’t there before, well, you know who to call.

Sprint and Verizon may have shunned the Nexus One, but that doesn’t mean the handsets can’t be put to good use: these Android-controlled, Arduino-powered Cellbots now feature the one true Googlephone as the CPU. At Intel’s 2010 International Science and Engineering Fair in San Jose, we got our hot little hands on the DIY truckbots for the first time, and found to our surprise they’d been imbued with accelerometer-based motion control. Grabbing a Nexus One off a nearby table, we simply tilted the handset forward, back, left and right to make the Cellbot wheel about accordingly, bumping playfully into neighbors and streaming live video the whole time. We were told the first handset wirelessly relayed instructions to the second using Google Chat, after which point a Python script determined the bot’s compass facing and activated Arduino-rigged motors via Bluetooth, but the real takeaway here is that robots never fail to amuse. Watch our phone-skewing, bot-driving antics in a video after the break, and see what we mean.
