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."

A Wired article (as carried by CNN) attempts to answer the question of why 3D television hasn't caught on. The reasons listed there (high price, paltry content, the need for 3D glasses for typical sets, headaches and strain) all seem to be on the money, in themselves, but I think don't go far enough. 3D on a set small enough for home use outside a high-end home-theater rig seems to me like a clever novelty that I can't even enjoy unless I've given it my full attention. It's nothing like the jump from black-and-white to color, or even the jump from my old (circa 1993) 19" Trinitron to a flat-panel display. On the big screen, it's another story — there, 3D can be arresting and involving, even when it's exaggerated (and it is). On home sets, even quite large ones, to my eye 3D usually looks phony and out of place. Never mind that the content is limited and often expensive, or that there are competing standards for expensive glasses to wear — I just don't like that the commitment is greater than that required for casual, conventional TV; I can't readily scan email, skim through a magazine, or keep watching out the corner of my eye from another room. (I'm hoping to find some actually watchable no-glasses 3D sets at CES next week, but I'm skeptical.)

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."

rtoz writes with the news that Chinese viewers will soon be able to watch a 3D TV channel service, to be opened in late January. Excerpting: "The first stations for the 3D trial are China Central Television, Beijing Television, Tianjing Broadcasting TV, Jiangsu TV and Shenzhen TV. 3D programs will be offered daily from 10:30 am to midnight. The programs include animation, sports, documentaries, TV dramas, entertainment and live broadcasting of big events, such as CCTV New Year's Gala and the London 2012 Olympic Games. The stations will charge no viewing fees during the early phase of operation."

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."

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."

McGruber writes "Following up on the earlier Slashdot story, the Christian Science Monitor now reports that GPS spoofing was used to get the RQ-170 Sentinel Drone to land in Iran. According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.' Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian engineers were able to get the drone to 'land on its own where we wanted it to, without having to crack the remote-control signals and communications.'"

First time submitter StatureOfLiberty writes "The California Near Space Project launched a high altitude weather balloon from San Jose, California 4:00 PM local time Sunday afternoon (Dec 11). Over the past 3 days it managed to cross the United States and then the Atlantic Ocean. The balloon passed the coastline of Spain about 12:40 AM (US Eastern Standard Time) Wednesday morning (Dec 14). It has since popped and landed in the Mediterranean Sea. This is a huge accomplishment. The previous distance record was about 3,300 miles. This one traveled about 6,200 miles. Enthusiasts tracked the balloon via the web throughout most of the trip thanks to a ham radio technology called APRS which received data transmitted by the balloon and logged it to databases on the internet. Thanks to APRS stations around the world (some of whom changed their normal listening frequencies to help with the tracking process) data was available for most of the flight."

Nate the greatest writes "Can you play an MP3 file? Then you can jailbreak the new Kindle Touch. A new hack was posted this morning that roots the Kindle Touch/K5 and opens the way for future hacks. The hacker also reveals that the K5 runs on HTML5, which should make it a lot easier to come up with new apps. Epub, anyone?"

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."

TheNextCorner writes "Glide over the giant asteroid Vesta with NASA's Dawn spacecraft in a new 3-D video. Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements." You'll need some red/green or red/blue glasses for the 3D effect.

Trailrunner7 writes "A group of researchers is claiming that they've found a root exploit that enables them to jailbreak the BlackBerry PlayBook tablet made by Research In Motion. In a video demonstration of the jailbreak, one of the researchers shows off the ability to change the settings on a PlayBook and says that he also has the ability to install the Android Market app on the tablet."

mikejuk writes "Are we getting closer to really effective volumetric 3D display technology? A new display, designed in Russia, uses cold fog and a laser projector to create a volumetric 3D image that you can touch. A tracking device (no, it's not a Kinect) is used to detect the user's hand and moves the virtual objects in response. There have been cold fog 3D displays before, but this one has a reasonable resolution and looks near to being a finished product that could be on sale soon. Estimated price? Between $4000 and $30,000."

MrSeb writes with an article in Extreme Tech about progress toward getting an AOSP build working on the Nexus S. From the article: "Over the past week, ROM Manager extraordinaire Koush has been frantically working on making a working build of CyanogenMod 9 (Ice Cream Sandwich) for the Samsung Nexus S. The custom ROM, which is built purely from the Android Open Source Project, has now reached 'alpha 11.' All major features are present and no significant bugs remain. It's too early to say that the build is ready for prime time or mission-critical work — the final release of CM9 is due in the new year — but it's certainly stable enough for daily use. The most significant feature, if you can call it that, is that Koush's build of ICS is really very smooth — it's as nimble as Gingerbread, if not more so. Unlike the previous, non-CM build that was released last week, this alpha build of CM9 has every feature enabled, including Google Wallet, and setting a mobile data limit. As usual, the custom ROM is pre-rooted, has ROM Manager installed, and absolutely no bloatware. "

ryzvonusef writes "Instructables Member 'Dimovi' utilized a spare LCD monitor and converted it into a 'privacy' monitor. He took apart the monitor's plastic frame, cutting out the polarized film with a utility knife and removed the film adhesive from the glass panel before reassembling the monitor, which now shines a bright white regardless of what is actually being displayed on the screen. He then removed the lenses from a pair of theater 3D glasses, and replaced it with the polarized film he had just removed from the monitor. Now, he is the only one who can see what he is doing on his computer."

Zothecula writes "Russian aircraft company MiG is best known for its fighter planes which have been used by the USSR, China, North Korea and North Vietnam since the beginning of WWII. These days, the former Government-owned RAC MiG is a publicly traded entity and competes on the open market with its technologies, having more than 1600 of its MiG-29 fighters in operation in 25 countries. Now MiG is claiming a major first in military aviation with the launch of a 3D flight simulator at the Dubai Air Show, providing volumetric visualization of beyond-the-cockpit space for trainee top guns. The simulator comes complete with the MiG-29's cockpit and actual control systems."

RulerOf writes "A few years ago, my girlfriend's grandfather was diagnosed with Macular Degeneration. Ever since, he has had progressively more trouble with daily activities. While his wife and family are able to help him with most things, at the age of 88 and without many living friends left, he dearly misses the ability to read printed text. He was able to get by for some time with magnifying glasses and other basic aids but now even those do not help. Recently, a local clinic which specializes in treatment for low-sight and blind individuals made him aware of and showed him several assistive reading devices that successfully allowed him to read. He mentioned this to his family members, and when I was told about it, I thought that these devices sounded like they were not much more than a camera attached to an LCD monitor or television with a little bit of special software thrown into the mix."

taweili writes "According to a tweet from Shanghai Morning Newspaper's Weibo account, the Shanghai Government Technology committee has issued a call for a proposal to build 100 community hackerspaces with government funding for equipment and a community managing the spaces. Hackerspaces have been growing rapidly in China since the first one, XinCheJian, was started in Shanghai last November as reported here by CNN Go. Currently there are three hackerspaces in China, with XinCheJian in Shanghai, Maxpace in Beijing and Chaihuo in Shenzhen. It looks like the governments are paying attention to the trend and are getting into supporting (or 'regulating') the movement."

With his first accepted submission, billakay writes "A recently open-sourced experimental Linux infrastructure created by Bell Labs researchers allows 3D rendering to be performed on a GPU and displayed on other devices, including DisplayLink dongles. The system accomplishes this by essentially creating 'Virtual CRTCs', or virtual display output controllers, and allowing arbitrary devices to appear as extra ports on a graphics card." The code and instructions are at GitHub. This may also be the beginning of good news for people with MUX-less dual-GPU laptops that are currently unsupported.
