New submitter upontheturtlesback writes "Another example of Star Trek technology becoming a reality. In light of the recent Tricorder X-Prize announcement, Dr. Peter Jansen has openly released the designs for a series of Science Tricorders that he developed while a graduate student at McMaster University. The Science Tricorders are capable of sensing a variety of atmospheric, electromagnetic, and spatial phenomena. Where the Science Tricorder Mark 1 is a relatively easy-to-build proof of concept, the Science Tricorder Mark 2 runs Linux and resembles a cross between a Nintendo DS and scientific instrument with dual OLED touch displays. An exciting video shows them in action, and describes the project goal of creating general scientific tools for learning about and visualizing the world, as well as their importance for science education by helping kids understand abstract concepts like magnetism or polarization visually. The hardware schematics, board layouts, and firmware source are freely available on the Tricorder project website under various open licenses."

mikejuk writes "Kurt Grandis took some cutting edge and open source AI tools, Python, an Arduino and a SuperSoaker and built the (almost) perfect squirrel hosing machine. The project involved Open Computer Vision (OpenCV), an a SVM learning procedure that he trained to tell the difference between a squirrel and a non-squirrel. After 'perfecting' the classifier the hardware came next — a SuperSoaker Mark I was used as the 'water cannon.' A pair of servos were used to aim the gun and a third to pull the trigger."

As a nexus of both computer programmers and other creative builder and maker types, SXSW (and Austin generally) is a great place to witness the overlap. John Zitterkopf and his pal Red, while helping to run the giant (and charitable!) LANFest at this year's event, had on hand for display a few of their own modded computer cases. John and Red are both part of Austin Modders, which helps Austinites swap tools and ideas (in-person, and via forums) for creating the kind of enclosures that computer makers simply can't — they're too time-intensive and too personalized for that. It's especially fun to see the effects that the newly widespread availability of laser cutters makes possible. (C'mon, O'Reilly, isn't it time for another Austin Maker Faire?)

JohnGrahamCumming writes "In this simple project, a hacked Linksys WRT54GL talks to a public API to get real-time bus information, and displays the times of the next buses on a model bus. Never miss the bus again! 'It's possible to reflash the Linksys with a custom Linux installation that lets me control the box completely (and still use it as a wireless router). There are various project, but I used OpenWRT. With OpenWRT it's possible to SSH into the box and treat it as any Linux server (albeit a rather slow one). But there's plenty of power to grab bus times and update an LED display connected to the WRT54GL's serial port. "

mkwan writes "A PhD student in Melbourne, Australia, has built an augmented reality head-up display using a baseball cap, an Android smartphone, and off-the-shelf optics. It won't win any awards for style or practicality, but it's a fun way to use Wikitude. All we need now is a Terminator-vision smartphone app." Not nearly as modern, but vaguely related: the Private Eye P4.

pigrabbitbear writes with an excerpt from an article at Motherboard: "Anyone planning on buying a new iPad should know what they're getting themselves into by now. In recent years, Apple and other hardware manufacturers have made it liquid-crystal clear that they're not fond of the idea that customers can tear open and fix products without the help of licensed repair specialists. Even if it's as easy as ordering a part online and following a few instructions gleaned from a Google search, hardware companies generally seem to prefer we keep the hood closed. It should not be surprising, then, that the latest version of Apple's much-desired tablet has one 'killer' feature that's finally getting the attention it deserves: A design that stops you from getting inside of it."

ptorrone writes "MAKE Magazine asks: is it 'Time For Girl Scouts and Boy Scouts 2.0?' What might the future of education be like if it were based on online & earned skill badges, and what could the future of traditional organizations for kids, like the Boy Scouts and Girl Scouts, be like in a very modern, tech-savvy world? Social networks and the maker movement are the perfect intersection of where the kids of today are, but we don't see 'leaderboards' for skills yet; we only see them for video games. Is it time for Hacker Scouts?"

Damien1972 writes "Conservationists have converted a remote-controlled plane into a potent tool for conservation. The drone — an HK Bixler equipped with cameras, sensors and GPS — has been used to map deforestation, count orangutans and elephants, and get a bird's eye view of hard-to-access forest areas. During their 4 days of testing in Sumatra, the drone flew 30 missions without a single crash. A mission, which typically lasts about 25 minutes, can cover 50 hectares. The drone, full equipped, costs less than $2,000."

Metrix Create:Space is full of people busily making electronic gadgets. And shot glasses. And everything in between. Some of them saw the street-level sign and stopped in out of curiosity, while others are long-time createspace scenesters. It doesn't matter which you are, says Metrix founder Matt Westervelt. Come in and make something. Need new skills? They have workshops. And lots of great tools.

HerbieTMac writes "Political science professor Francis Fukuyama builds and flies his own personal surveillance drones. His current model requires ground visibility but he is working on the HAM license that would allow fully remote operation. His YouTube videos (video 1 , video 2) are particularly impressive." I had no idea that Francis Fukuyama had such technical interests.

acadiel writes "Matthew H from the AtariAge.com TI-99/4A forum has finalized a design of a TMS 9918A replacement (with VGA out) for classic computer systems such as the ColecoVision, TI-99/4A, SpectraVision, MSX1, SpectraVision 128, and Tomy Tutor Home computers. This hardware project replaces the native video controller on these classic systems and enables them to have VGA output for the first time." (It's just under $100 to order one.)

Qa32 writes "I am getting married in a few months and being a hardcore techie I wanted to come up with some novel way of making my wedding invite that will truly have even my mom say, 'wow, that was cool.' Has anyone out there done anything similar, or have you thought of something similar you'd like to share? I already have a few: have QR codes, have some basic embedded circuit/plate with wire leads that maybe plays a song when you connect a battery, have a way to turn up a display LCD, etc."

An anonymous reader writes "A guy who goes by the online handle DDRBoxman decided it would be fun to blow up his Samsung Galaxy Nexus display onto the wall by connecting his phone to a projector. He then connected the whole thing to a PC and, thanks to Microsoft's open-source Kinect platform for Windows, he was able to create a custom ROM that mapped out the phone interface to the Kinect sensors. Pretty neat!"

An anonymous reader writes with news from Geek.com on an expansion board for the Raspberry Pi. Quoting: "In the middle of December last year the Raspberry Pi Foundation made a surprising announcement that not only would we see the $25 PC released in 2012, it would also be getting an expansion board ... called the Gertboard, and is being developed by Broadcom employee Gert van Loo in his spare time. When completed, it will allow Raspberry Pi owners to play around with flashing LEDs, electric motors, and a range of different sensors. It effectively takes the $25 Raspberry Pi beyond just being a very cheap PC. There's a video of the Gertboard already working which demonstrates the 12 LEDs being lit up and the board powering an electric motor more than capable of lifting something like your garage door."

An anonymous reader writes "Grad students at UC Irvine have built a spatial frequency domain imaging system using parts from a cheap LCD projector and a digital camera. The system can be used to check the level of bruising or oxygenation in layers of tissue that aren't visible to the naked eye, according to an article in Chemical and Engineering News. An accompanying video shows the series of patterned pulses that the improvised imaging system makes in order to read hemoglobin and fat levels below the surface of the skin. A more sophisticated version of the imaging system is being commercialized by a startup within UC Irvine, called Modulated Imaging. The article and video also describe infrared brain scanners that can non-invasively check for brain bleeds, and multiphoton microscopes that produce stunning images of live skin cells."

MojoKid writes "Renowned overclocker 'Hicookie' achieved a new high clock speed on the Intel Core i7 3930K processor by cranking the chip past 5.6GHz using a Gigabyte GA-X79-UD3 motherboard, the first mobo in the world to achieve a mulitplier of 57x. There was a bit of a scandal with Gigabyte recently when a YouTube video showed one of its X79 boards going up in smoke. Gigabyte released a BIOS update for several of its X79 boards to prevent such incidents from happening, and there were outcries that the new F7 BIOS would ... [reduce] overclocking performance; Hicookie's achievement should erase those concerns."

jfruhlinger writes "Tired of your code only executing in digital space? Why not hack your smiling snowman? OK, this crash course only shows you how to make pretty LED lights blink in a sequence of your choosing, but it serves to introduce you to Arduino, an open-source platform that uses C-like code. Really, any project that involves a soldering iron is good fun."

YokimaSun writes "Mamosuke, a PSP Homebrewer from Japan, has posted the first Hello World on the PS Vita which comes from the PSP Emulator in the console. Using a buffer overflow, he has found a way into the PSVita, and with many PSP Game exploits still around and not published for the whole homebrew and hacking community this means that in the short term homebrew is here on the PSvita. Lets hope this is the start of a true PSVita homebrew scene."

Trailrunner7 notes that some dedicated hackers who've been working on jailbreaking RIM's PlayBook tablet have now "posted a detailed walkthrough of how users can accomplish the same task on their own. The technique requires the use of a custom tool, but otherwise is fairly straightforward. One of the researchers, known as Neuralic, posted the walkthrough to Pastie.org Tuesday morning. In order to begin the process, a PlayBook user need to first install the beta 2.0 version of the PlayBook software and then install the Dingleberry tool, which exploits a weakness in the PlayBook architecture which stems from the fact that the backups the device takes aren't signed."
