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.

After his amateur rocket flight in the desert (to 121,000 feet!), you asked rocket enthusiast Derek Deville about the project. Derek's responded to a selection of the best of those questions; read on below for his replies.

First time accepted submitter Gortu writes "We are describing and demonstrating a 3D Volumetric Projector (YouTube video); in short words: a device that enables mixed reality. The 3D projector has very poor quality, we just have 10 rotational voxels (as we are using only 10 regular LCD projectors), but is proof of concept for developing a commercial solution."

blackbearnh writes "For many adults into technology, childhood was an alienating experience, pigeon-holed as a nerd and relegated to the A/V, Computer or Gaming club in high school. But according to a Christian Science Monitor article that looks at young Makers, the next generation of tech geeks are social and are gaining increasing support from corporate America. Radio Shack is stocking Arduinos, Autodesk bought Instructables, and teens are flocking to local Hackerspaces to learn how to create their own gear. Wired GeekDad David Giancaspro thinks the desire to create things is natural. 'As we've moved further and further away from that, towards what people call "knowledge work," as opposed to producing something physical, that urge is starting to come back,' he says."

ematic writes with a link to an interesting competition from DARPA: "The ability to reconstruct shredded documents will potentially yield information that may save lives or offer critical information about an adversary's plans. Currently, this process is much too slow and too labor-intensive, particularly if the documents are handwritten. We are looking to the Shredder Challenge to generate some leap-ahead thinking in this area. The Shredder Challenge is composed of five separate problems. The overall prize awarded depends on the number and difficulty of problems solved."

Hallowe'en is just around the corner. I've spent hours this month poring over masks, fog machines, automated monsters, and sound-activated dancing skeletons (mostly too rich for my blood), and worked with my brother and sister to haunt my mom's house with scary pictures, mounds of spider-webbing, sound effects, strobe lights, stage blood, candles, and rusty knives. Like every year, though, the best laid plans are the ones you come up with after the fact (why do I always plan to build a coffin with Bible-repelling magnetic lid and matching Bible, but never do?), and while our effort was fun and satisfying, it definitely didn't push the envelope. (There's plenty of good inspiration out there, though, for people who do want to go a little crazy.) So I ask: What are you doing to celebrate the spirit of Hallowe'en? In particular, are you using any good stagecraft-style tech to make your dwelling, yard, or neighborhood just a little bit scarier than usual? Any good advice based on previous haunting experiences, either as haunter or hauntee? What effects do you wish you could create, given enough time and money? Do you control any aspect of your display by computer? Think broadly: Links to inspiring commercial haunts, sources of interesting gear, and your favorite house-haunting projects at Instructables are all welcome, as well as relevant advice from the parts of the world where Hallowe'en isn't the major event that it is in the U.S.

An anonymous reader writes "As the launch of the $25 PC gets ever closer (sometime next month), members of the Raspberry Pi team have found time to start blogging about the history of the project. Eben Upton, director of the Raspberry Pi Foundation, has been working on the project for many years, and decided to share a couple of very early prototypes for the $25 PC with the community. The 2006 edition of the PC used an Atmel ATmega644 microcontroller. It ran at 22.1MHz with 512K of SRAM. Compare that to the final version of the PC, which will use a 700MHz ARM11 processor and 128MB/256MB of SDRAM. Five years clearly brings a massive leap in performance. For those of us happy to play around with components at this level, Eben has made the schematics and PCB layout available to download (ZIP file). Armed with this information you can create your very own 2006 Raspberry Pi machine."

An anonymous reader writes "The Jumentum open source project has announced a single-chip programming system based on the NXP LPC1768 (the same as in the mbed) that can generate PAL/NTSC video and use a PS/2 keyboard, so it may operate as a standalone BASIC programmable computer, similar to many old BASIC computers (e.g. Apple ][ or C64) of yore. Projects such as the Raspberry Pi provide a multichip Linux solution, and the Humane PC uses three AVR microcontrollers, but the Jumentum system can provide a true one-chip solution. Video is generated by software, and only a few external resistors are required to interface to a composite video input. With the Jumentum system, you can take your tiny one-chip computer on-the-go, or use it as part of your own electronics projects (using for example, the mbed) to give it a convenient interface (along with Jumentum's Ethernet web and USB interfaces)."

Hugh Pickens writes "DARPA reports that more than $300 billion worth of satellites are in the geosynchronous orbit, many retired due to failure of one component even if 90% of the satellite works just as well as the day it was launched. DARPA's Phoenix program seeks to develop technologies to cooperatively harvest and re-use valuable components such as antennas or solar arrays from retired, nonworking satellites in GEO and demonstrate the ability to create new space systems at greatly reduced cost. However, satellites in GEO are not designed to be disassembled or repaired, so it's not a matter of simply removing some nuts and bolts, says David Barnhart. 'This requires new remote imaging and robotics technology and special tools to grip, cut, and modify complex systems.' For a person operating such robotics, the complexity is similar to trying to assemble via remote control multiple Legos at the same time while looking through a telescope."

ptorrone writes "Imagine waking up and seeing your design for a circuit being used in a product by someone who never contacted you to ask if it was okay. You will not get any payment for their usage of your design, they've raised over $31,000, and they're selling something you worked really hard on. You have no control over what someone does with something you made. Is this a nightmare? Perhaps for some, but this is actually a dream come true for others who do open-source hardware. MAKE magazine profiles a maker using open-source hardware for his now-funded project and looks at others using open hardware for their works."

lekernel writes "The Milkymist project (also mentioned earlier this year) have started shipping their so-called 'video synthesizer,' a device used by concert and other event organizers to create live visual effects. Most interestingly, the device is based on their fully open source system-on-chip design, including both a CPU and graphics accelerators — the latter being a significant part of what the Open Graphics project is still struggling with."

First time accepted submitter misterbarnacles writes "The Microtouch is a mobile media device that aims to become an open-source alternative to the iPod Touch." Deeper investigation reveals that the Microtouch is a nifty little device. Powered by an 8-bit microcontroller with only 2.5K of RAM there is an example ebook reader application. A primitive application framework (for some definition of the phrase) is available as Free Software, and for the hardware hackers the EagleCAD PCB files are published under a CC attribution-share-alike license.
