Hasta La Gadget!

There were certainly a couple whiz kids at Intel’s International Science and Engineering Fair this year, but high school senior John Hinckel’s a regular MacGyver: he built a wheelchair remote control out of a couple sheets of transparent plastic, four sliding furniture rails and some string. A Nintendo Wiimote goes in your hat and tells the whole system what to do — simply tilt your head in any direction, and accelerometer readings are sent over Bluetooth. The receiving laptop activates microcontrollers, directing servo motors to pull the strings, and acrylic gates push the joystick accordingly to steer your vehicle. We tried on the headset for ourselves and came away fairly impressed — it’s no mind control, but for $534 in parts, it just might do. Apparently, we weren’t the only ones who thought so, as patents are pending, and a manufacturer of wheelchair control systems has already expressed interest in commercializing the idea. See the young inventor show it off after the break.

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.

From the man that brought you the OS Xbox Pro and the Cinematograph HD comes… a cockpit canopy filled with hard drives? Not quite. Meet the Black Dwarf, a custom network-attached-storage device from the mind of video editor Will Urbina, packing 16TB of RAID 5 magnetic media and a 1.66GHz Atom N270 CPU into a completely hand-built Lexan, aluminum and steel enclosure. Urbina says the Dwarf writes at 88MB per second and reads at a fantastic 266MB per second, making the shuttlecraft-shaped 12.7TB array nearly as speedy as an SSD but with massive capacity and some redundancy to boot. As usual, the DIY guru shot a professional time-lapse video of his entire build process, and this one’s not to be missed — it showcases some pretty spiffy camerawork as well as the man’s welding skills. See sparks fly after the break.

We told you you could shave down your old and busted SIM cards and turn them into minty fresh Micro SIMs, didn’t we? An industrious Londoner by the name of John Benson has gone and proven that concept with the help of some cutting implements and an original Micro SIM to use as a reference. His saintly patience resulted in his being able to negotiate the Vodafone SIM you see above into his iPad 3G (imported from the USA) and riding the waves of Voda’s network as if Apple never decided to encumber its portable device with a silly new standard. The 3FF (Micro) SIMs and the bulkier original ones are electrically identical, so there’s no threat of harm by using them interchangeably, though we can’t say the same thing about the tools that get you there. As always, we advise trying to rope someone else into doing the work for you — less chance of hurting yourself that way. Hit the source for more.

[Thanks, Brandon]
