Canon DSLR Hack Allows It To Shoot RAW Video 171

When the Canon 50D DSLR camera was released back in 2008, it could take nice pictures, but it had no support for video recording. Now, through an enterprising hack by members of the Magic Lantern forums, the 50D can capture RAW video. From the article: "The tech inside the 50D looks like it borrows a lot more from its higher-end siblings, like the 5D Mark II, and it’s possible we may actually get better RAW video quality out of the 50D than we do out of any of the non-CF Canon cameras. ... The camera doesn’t have playback or audio recording as it was never designed to shoot video, but this isn’t too different from the RAW recording on the other Canon DSLRs at the moment."

Vastly Improved Raspberry Pi Performance With Wayland 259

New submitter nekohayo writes "While Wayland/Weston 1.1 brought support to the Raspberry Pi merely a month ago, work has recently been done to bring true hardware-accelerated compositing capabilities to the RPi's graphics stack using Weston. The Raspberry Pi foundation has made an announcement about the work that has been done with Collabora to make this happen. X.org/Wayland developer Daniel Stone has written a blog post about this, including a video demonstrating the improved reactivity and performance. Developer Pekka Paalanen also provided additional technical details about the implementation." Rather than using the OpenGL ES hardware, the new compositor implementation uses the SoC's 2D scaler/compositing hardware which offers "a scaling throughput of 500 megapixels per second and blending throughput of 1 gigapixel per second. It runs independently of the OpenGL ES hardware, so we can continue to render 3D graphics at the full, very fast rate, even while compositing."

Google Releases Glass Factory System Image, Rooted Bootloader 74

Krystalo writes "In a nod towards the modding community and hackers in general, Google has released the first factory system image and rooted bootloader for the latest version, XE5, of Google Glass. Nevertheless, the company is at the same time warning that using these downloads will result in a voided warranty for the experimental device."

Working Handgun Printed On a Sub-$2,000 3D Printer 521

Just a few weeks after Cody Wilson and friends successfully fired an instance of their own 3-D printed handgun design, Sparrowvsrevolution writes, "a couple of Wisconsin hobbyist gunsmiths have already managed to adapt Defense Distributed's so-called Liberator firearm and print it on a $1,725 Lulzbot 3D printer, a consumer grade machine that's far cheaper than the industrial quality Stratasys machine Defense Distributed used. They then proceeded to record their cheaper gun (dubbed the 'Lulz Liberator') firing nine .380 rounds without any signs of cracking or melting. Eight of the rounds were fired from a single plastic barrel. (Defense Distributed only fired one through its prototype.) In total, the Lulz Liberator's materials cost around $25 and were printed over just 48 hours."

Ask Slashdot: Wiring Home Furniture? 235

b1tbkt writes "So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?"

Arduino Branches Out, With a Plug-and-Program Robot 24

mikejuk writes "The new Arduino robot looks a bit like a robot vacuum cleaner, but it has a lot more going for it and it certainly doesn't suck — well not unless you add an air pump to it. As always, the Arduino Robot is completely open source and comes as an easy to assemble kit involving no soldering, just some plugging in of components. It consists of two circular boards, 19cm in diameter, each with its own Arduino controller. They fit together to create a stack about 10cm tall. The bottom board has two wheels and motors which allow it to move in any direction. The top board contains lots of sensors and a central display. The two communicate via a serial connection. There is also a lot of space for expansion. There is a new library which can be downloaded to help write programs for this fairly sophisticated robot. There is only one big problem with the Arduino robot — you can't buy one at the moment. If you really can't wait, until early July when they should start shipping from the Arduino shop and from distributors, then you will have to get to the Maker Faire San Mateo (May 17-19) where they are being demonstrated and sold."

RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks 79

New submitter TheJish writes "The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build. While there have certainly been larger RPi clusters put together recently, I figured the Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis."

Make Your Own Invisibility Cloak With a 3D Printer 80

cylonlover writes "Invisibility cloaks have been around in various forms since 2006, when the first cloak based on optical metamaterials was demonstrated. The design of cloaking devices has come a long way in the past seven years, as illustrated by a simple, yet highly effective, radar cloak developed by Duke University Professor Yaroslav Urzhumov, that can be made using a hobby-level 3D printer."

California Lawmaker Wants 3-D Printers To Be Regulated 856

New submitter phrackthat writes with news that California State Senator Leland Yee (D-S.F.) says he wants regulations to track who owns and uses 3-D printers. Yee's comments come in response to the recent news of Defense Distributed's successful test-firing of a 3-D printed gun. "He's concerned that just about anyone with access to those cutting-edge printers can arm themselves. 'Terrorists can make these guns and do some horrible things to an individual and then walk away scott-free, and that is something that is really dangerous,' said Yee. He said while this new technology is impressive, it must be regulated when it comes to making guns. He says background checks, requiring serial numbers and even registering them could be part of new legislation that he says will protect the public. Yee added, 'This particular gun has no trace whatsoever.'"

DoD Descends On DEFCAD 496

First time accepted submitter He Who Has No Name writes "While the ATF appears to have no open objection to 3D printed firearms at this time, the Department of Defense apparently does. A short while ago, '#DEFCAD has gone dark at the request of the Department of Defense Trade Controls. Take it up with the Secretary of State' appeared on the group's site, and download links for files hosted there began to give users popups warning of the DoD takeover." Well, that didn't take long. Note: As of this writing, the site is returning an error, rather than the message above, but founder Cody Wilson has posted a similar message to twitter. At least the Commander in Chief is in town to deliver the message personally. Update: 05/09 21:17 GMT by T : Tweet aside, that should be Department of State, rather than Department of Defense, as many readers have pointed out. (Thanks!)

Printable Gun Downloads Top 100k In 2 Days, Thanks to Kim Dotcom 656

Sparrowvsrevolution writes "The promise of a fully 3D-printable gun is that it can spread via the Internet and entirely circumvent gun control laws. Two days after that digital weapon's blueprint first appeared online, it seems to be fulfilling that promise. Files for the printable gun known as that 'Liberator' have been downloaded more than 100,000 times in two days, according to Defense Distributed, the group that created it. Those downloads were facilitated by Kim Dotcom's startup Mega, which Defense Distributed is using to host the Liberator's CAD files. And it's also been uploaded to the Pirate Bay, where it's one of the most popular files in the filesharing site's uncensorable 3D printing category."

The First Fully 3D-Printed Gun Has Been Successfully Test-Fired 717

On Friday, we mentioned that Defense Distributed had created a (near-enough-to) fully 3-D printed pistol. Sparrowvsrevolution now writes that "Last week, the Liberator was fired for the first time at a firing range and successfully shot a .380 caliber bullet using a remote firing setup. Over the weekend, Defense Distributed's founder, the anarchist and radical libertarian Cody Wilson, was bold enough to try firing it by hand. The results of that test, witnessed by a reporter, indicate that the era of the 3D-printed firearm may be upon us, for better or for worse." Predictably, certain politicians are — so to speak — up in arms about it.

Defense Distributed Has 3D-Printed an Entire Gun 712

Daniel_Stuckey writes with this snippet from Motherboard with an update on Cody Wilson's Defense Distributed project: "On Friday morning, Forbes's Andy Greenberg published photos of the world's first completely 3D-printed gun. It has a 3D-printed handle, a 3D-printed trigger, a 3D-printed body and a 3D-printed barrel, all made of polymer. It's not completely plastic, though. So as not to violate the Undetectable Firearms Act and guarantee it would get spotted by a metal detector, Wilson and friends embedded a six-ounce hunk of steel inside the gun. They're calling it 'The Liberator.'" (A name I'm sure that Wilson didn't come up with accidentally.)

Staples Starts Selling 3-D Printer 65

An anonymous reader writes "Soon anyone will be able to head out to the store and buy a 3D printer: 'Staples, one of the leading office supply retailers in the U.S. announced it would begin selling 3-D Systems' entry level personal 3-D printer, The Cube. This is quite simply the single largest 3-D printer retail move to date by any 3-D printer manufacturer.' 'The Cube is one of a number of 3-D printers designed with traditional consumers in mind. Specifically, this unit can print items up to 5.5 inches tall, wide and long in one of 16 different colors. The retail bundle includes 25 free design templates to get users started but the real fun is designing and building something all your own.'"

BotObjects Announces First Full-Color Desktop 3D Printer 29

Zothecula writes "In the ProDesk3D, 3D printing outfit botObjects has come up with not only the first full color desktop 3D printer, but thanks to its anodized aluminum body, unquestionably one of the prettiest. The company's goal was to think about how 3D printers might look in 5 years, aiming to put clear water between the ProDesk3D and its "kit-like contemporaries." To print in color, it uses a cartridge system capable of mixing five base colors of PLA."

New OpenWRT Drops Support For Linux 2.4, Low-Mem Devices 194

hypnosec writes with word that the OpenWRT team a few days ago released the final version of the project's newest iteration, version 12.09 (codenamed "Attitude Adjustment"). "The final version doesn't support Linux 2.4, because of which the distribution wouldn't run on old router models, for example the Linksys WRT54G models, which have 16MB of RAM and CPUs clocked at 200MHz. The distribution is now based on Linux 3.3 and there is good news for the Raspberry Pi fans as the distribution now supports the credit card-sized computer, along with Ramips routers."

$5 Sensor Turns LCD Monitors Into Touchscreens 98

An anonymous reader writes with this snippet from ExtremeTech: "Researchers at the University of Washington's aptly named Ubiquitous Computing Lab can turn any LCD monitor in your house into a touchscreen, with nothing more than a $5 sensor that plugs into the wall and some clever software." The system works by measuring changes that your hand creates in the electromagnetic signature of the monitor. Surprisingly, it offers some pretty fine-grained detection, too: "full-hand touch, five-finger touch, hovering above the screen, pushing, and pulling." The "$5 sensor" part is mostly theoretical for now to those of us who don't live in a lab, though; on the other hand, "co-author Sidhant Gupta tells Technology Review that the $5 sensor uses off-the-shelf parts, and the algorithms are included in the paper, so it would be fairly easy for you — or a commercial entity — to recreate the uTouch system."

BeagleBone Black Released With 1GHz Cortex-A8 For Only $45 142

DeviceGuru tipped us to the release of the latest single board computer from Beagle Board. It's been two years since the previous BeagleBone was released, and today they've released the BeagleBone Black (including full hardware schematics) at a price competitive with the Raspberry Pi ($10 more, but it comes with a power brick). Powered by a Cortex-A8, it has 512M of DDR3 RAM, 2G of onboard eMMC, two blocks of 46 I/O pins, a pair of 32-bit DSPs, the usual USB host/client ports, Ethernet, and micro-HDMI (a much requested feature). Support is provided for Ångstrom GNU/Linux, Ubuntu, and Android out of the box. Linux Gizmos reports where some of the cost savings came from: "According to BeagleBoard.org cofounder Jason Kridner, interviewed in a Linux.com report today, cost savings also came from removing the default serial port as well as USB-to-serial and USB-to-JTAG interfaces, and including a cheaper single-purpose USB cable. (Three serial interfaces are available via the expansion headers.) In addition, the power expansion header for battery and backlight has been removed."

Happy Hardware Freedom Day 35

Blug_fred writes "For the first year the Digital Freedom Foundation (ex-SFI) is organizing Hardware Freedom Day. With 66 events worldwide split over 36 countries, they are not yet covering the whole world but it is a good start. So if you have always been wondering about hacking your own stuff, be it a piece of wood or some more complex electronic gears then it is time to join an open door day type of event. Sixty-six events is definitely less that the total number of hackerspaces around the world and you can check for other events happening in a hackerspace near you if none are celebrating today. Hopefully they will join the movement next year."
