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.

Bob the Super Hamste writes "Fortune magazine is reporting that the company Zebra Imaging is producing a 3D hologram table that will project a 360 degree 3D image that doesn't require glasses. Funding for this project is being provided by DARPA for battle planning. The company expects it will take at least another three years for the table to be ready for commercial applications."

Barence writes "PC Pro has published a comprehensive guide to installing Android on a HP TouchPad using CyanogenMod's alpha Android release. The mod, which is based on Android 2.3 (Gingerbread) instead of 3.0 (Honeycomb, the source code of which is yet to be released) 'performs similarly to the Tegra 2-based tablets we've seen from the likes of Asus and Samsung,' according to PC Pro. 'The only real problem we hit was some apps refusing to install from the Android Market because they didn't recognise the hardware,' although there are ways around it."

An anonymous reader writes "The New York Times is running a story on people hacking the Nissan Leaf electric vehicle. 'Using Mr. Giddings’s home-brewed E.V. fuel-level display, Leaf drivers get the confidence to extend their driving range by 10 percent or more. His gauge, which displays the actual state of charge, reveals that the Leaf dashboard’s "zero bars" display comes on when the battery pack has several miles remaining.' Here's an interesting quote from one of the hackers, Phil Sadow, who was interviewed for the story: 'I don't like the term hacking because it's been portrayed by the media as something evil. To me, hacking is actually very American. Go out to the garage. Take it apart. Make it better.'"

Nate the greatest writes "It's been just over a month since the T1 launched and only a couple weeks since it shipped — and it has already been hacked. A video has surfaced that shows the T1 running a number of apps, including a new home screen, AW Launcher, and a couple of different reading apps. It can't run Angry Birds just yet, but this is still great news. There aren't any details yet on when you'll be able to hack your T1, but I bet they'll be filtering out fairly soon."

99luftballon writes "The OccupySF team have been running an ad-hoc computer network on the streets of San Francisco without a steady power source, no Wi-Fi and even the occasional police raid. It turns out the best way to keep the lights on is car batteries and pedal power."

MrSeb writes "Jonas Pfeil, a student from the Technical University of Berlin, has created a rugged, grapefruit-sized ball that has 36 fixed-focus, 2-megapixel digital camera sensors built in. The user simply throws the ball into the air and photos are simultaneously taken with all 36 cameras to create a full, spherical panorama of the surrounding scene. The ball itself is made with a 3D printer, and the innards (which includes 36 STM VS6724 CMOS camera sensors, an accelerometer, and two microcontrollers to control the cameras) are adequately padded, so presumably it doesn't matter if you're bad at throwing and catching."

yesakmac joins the teeming hordes of successful Slashdot submitters, with this excerpt from PC World that says the frenzied effort to port Android to HP's discontinued TouchPad has actually succeeded: "CyanogenMod also released a 'lower your expectations edition' release guide to let you know exactly what is working (or not) under the hood. Modders will be happy to know that basically all the TouchPad's guts are recognized. It supports dual-booting and fake SD cards in case you need to restore the TouchPad. What does not work, though, is the camera, which can only be used for video chat. Power efficiency is still an issue, too. As for the final build, CyanogenMod says they won't be giving a hard date, and that it will be ready when it is ready."

Slate has reprinted the piece that Ron Rosenbaum wrote for Esquire in 1971, explaining to the world that there was an underground movement of people hacking the phone system. (Rosenbaum is now a columnist for Slate.) According to the article's new introduction and followup piece by Rosenbaum reflecting on its impact — and to the New York Times obituary for Steve Jobs — this article inspired Jobs and Wozniak to start building blue boxes themselves, an effort that made them several thousand dollars.

First time accepted submitter aonsquared writes "A couple of months ago I managed to scoop up a cheap (£30) robot arm with a USB interface from Maplin (I'm in the UK). Following a wrist injury which left me without the use of my right hand for 4 weeks, I decided to build it for a little hacking project. Using Linux, libusb and other freely available tools, I have enabled the robot arm to respond to my voice commands. I've posted a full tutorial and downloadable source code, as well as a demonstration video. Hopefully, open-source voice recognition as well as devices like the Kinect (which has spawned hundreds of different cool hacks) can someday revolutionise the way we interact with computers and machines."

hypnosec writes "Smartphone maker Sony Ericsson has decided to work closely with developers creating custom Android ROMs for devices in order to learn from them. The company said in a blog post that it has decided to support an open source developer group called 'FreeXperia,' which creates custom Android ROMs based on the CyanogenMod for several Sony Ericsson phones like the Xperia ARC and Play. Sony Ericsson maintained that it does not approve of some of the work carried out by independent developers but was keen to work with people who were creating custom ROMs."
