83-Year-Old Woman Gets New 3D-Printed Titanium Jaw 121

arnodf writes "The University of Hasselt (in Belgium) announced today (Google translation of Dutch original) that Belgian and Dutch scientists have successfully replaced an 83-year-old woman's lower jaw with a 3D-printed model. According to the researchers, 'It is the first custom-made implant in the world to replace an entire lower jaw. ... The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The artificial jaw is slightly heavier than a natural jaw, but the patient can easily get used to it."

Ask Slashdot: Techie Wedding Invitation Ideas? 399

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."

Android Kinect Projector Interface 45

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!"

Pirate Bay To Offer Physical Item Downloads 343

lukehopewell1 writes "The Pirate Bay is offering users the chance to download and print out real objects using 3D printers in what the pirate site is hailing as 'the future.'" Amir Taaki mentions that among the new "physibles" uploaded to the Pirate Bay are "plans for a tabletop replica for a Warhammer 40k dreadnought that got taken down in December with a DMCA request." Downloadable 3D models have been around for a while; MakerBot users are probably all familiar with the Thingiverse. Couple TPB with a cheap method of accurate 3D scanning, though, and I wonder what illegal shapes will emerge.

Ask Slashdot: Tips On 2D To Stereo 3D Conversion? 125

An anonymous reader writes "I'm interested in converting 2D video to Stereoscopic 3D video — the Red/Cyan Anaglyph type in particular (to ensure compatibility with cardboard Anaglyph glasses). Here's my questions: Which software(s) or algorithms can currently do this, and do it well? Also, are there any 3D TVs on the market that have a high quality 2D-to-3D realtime conversion function in them? And finally, if I were to try and roll my own 2D-to-3D conversion algorithm, where should I start? Which books, websites, blogs or papers should I look at?" I'd never even thought about this as a possibility; now I see there are some tutorials available; if you've done it, though, what sort of results did you get? And any tips for those using Linux?

Alternative Android Market To House Banned Apps 114

sl4shd0rk writes "In contrast to the Apple's iron-fisted control over their App store, the Android Market is much more open. Google does, on occasion, remove apps it deems inappropriate, such as emulators, legally-questionable music services, tethering apps and one-click root apps. But if Koushik Dutta of CyanogenMod fame has his way, these heretic apps may have a home after all. Dutta plans an 'underground' Android Market complete with an approval process to weed out malicious applications; something Google doesn't do. Ideally, this will give Android users a more trustable source from which to get applications without having to resort to dictatorial software control."

Silver Solution Ink Makes Faster Flexible Circuits 36

judgecorp writes "Silver-based compounds dissolved in ammonia could make finer and more flexible circuits, according to researchers at the University of Illinois. Existing inkjet based circuit printing systems use particles which are less predictable. The silver-based ink remains dissolved until the ammonia evaporates, and can be delivered through 100nm nozzles. In all senses, it's a better solution."

Raspberry Pi Gertboard In Action 191

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."

Makers Keep Flogging 3D TV, Viewers Keep Shrugging 457

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.)

Medical Imaging With a Hacked LCD Projector 57

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."

Gigabyte Board Sets Intel X79 Overclocking Record 113

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."

Hello World On PS Vita, Thanks to Buffer Overflow 123

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."

US Sentinel Drone Fooled Into Landing With GPS Spoofing 647

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.'"

Atlantic Crossing By Amateur Radio High Altitude Balloon 51

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."

PlayBook Jailbreak Tool Released 60

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."
