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!)

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."

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.

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.)

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.'"

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."

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."

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."

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."

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."

An anonymous reader writes "Hacker Benjamin Smith deconstructs the cycle of education, production, and rest that will be familiar to many software and hardware engineers. He breaks it down into four steps: 1) Focused effort toward a goal, 2) structured self-education, 3) side-projects to sharpen skills, and 4) burnout and rest. He writes, 'As my motivation waxes at the beginning of a cycle, I find myself with a craving to take steps towards that goal. I do so by starting a project which focuses on one thing only: building a new income stream. As a result of this single-mindedness, the content or subject of the project is often less interesting than it otherwise might have been. ... [Later], I almost always decide to teach myself a new technical skill or pick up some new technology. ... This is usually the most satisfying period of my cycle. I am learning a new skill or technology which I know will enhance my employability, allow me to build things I previously could only have daydreamed about, and will ultimately be useful for many years to come. ... [In the burnout phase], I'll spend this period as ferociously devoted to my leisure activities as I was to my productive tasks. But after a few months of this, I start to feel an itch...'"

New submitter drachensun writes "Francesco Santini was looking into the possibilities of stand-alone printing with the Solidoodle. He choose the PengPod 700, a tablet that runs a full Linux distribution and turned it into a standalone interface for the SD2. 'So, in summary, I now have a fully-functional touchscreen pronterface installation that can drive the Solidoodle, for a total cost of 110$. No assembly, soldering, firmware modding required. Just a little bit of fiddling with Linux (if required, I can post a step-by-step guide, or prepare an ad-hoc linux image).'"

anavictoriasaavedra writes "Adafruit Industries just posted the first episode in a new educational series aimed at teaching kids about electronics. The episode is entitled 'A is for Ampere' and teaches the basic theory behind electrical current. The subject seems like a common one for A-to-Z themed electrical tutorials. And yes, that's Collin Cunnigham as André-Marie Ampère."

He was the CTO at Microsoft, is an accomplished nature and wildlife photographer, and his cookbook Modernist Cuisine won a James Beard award, but Nathan Myhrvold is probably best known for being co-founder and CEO of Intellectual Ventures. In 2009 the company launched a prototyping and research laboratory called Intellectual Ventures Lab. The lab has hired many prominent scientists to work on a variety of inventions including safer nuclear reactor designs and vaccine research. Under Myhrvold's direction Intellectual Ventures has purchased 40,000 patents and applications and internally developed over 2000 inventions, but not without controversy. Nathan has agreed to take some time to answer your questions but please limit yourself to one question per post. As a bonus on Wed. April 3, Nathan will be doing a live Q&A from 12-12:30pm PDT.

Hesh writes "The University of Southern California has launched a website that contains the blueprints for many of their custom VR headsets as well as new mods to the much anticipated yet unreleased Oculus Rift. Some are helping push DIY VR forward through custom sensor mounts to support, for example, stereo cameras and others add more functionality like new eye cups to help increase the already large FOV of the headset. This is truly an exciting time for VR; by GDC, developers will already have Rifts in hand and tinkerers can 3D-print their own designs now as well!"

yanom writes "My school gave me several circa-2006 computers with no operating system. I fixed them up, and now they run Lubuntu fairly well, making them great internet/LibreOffice/general Linux workstations. I've been wanting to donate them to local nonprofits where they'll go to good use — for example, I've already given several to a local church for them to use in their afterschool care/tutoring program. However, I'm having trouble finding other places where these machines could go to good use. How should I best conduct this search? How can I find nonprofits that could benefit from these workstations?"

Hesh writes "With the impending arrival of the first batch of Oculus Rift VR headsets to developers, Rod Furlan put up a very detailed guide on how to build your very own headset with off-the-shelf parts and a few hours of spare time based off of the original design of the headset from the forums where it all started. This is a very exciting time for VR, and DIY headsets will allow everyone to try out new tricks and form factors while finally being able to test with a whole new world of compatible software that is about to be released very soon."

Sparrowvsrevolution writes that at this year's SXSW, Defense Distributed founder Code Wilson has announced a for-profit spinoff of his gun-printing project, from which people will be able to search for and download gun-related CAD files. "Though the search engine will index all types of files, Wilson says he hopes the group's reputation for hosting politically incendiary content will mean users trust that it won't censor search results. 'When we say you should have access to these files, people believe we mean that,' says Wilson. 'No takedowns. No removals. We'd fight everything to the full extent of the law.' Along with the SXSW announcement, Wilson also released a provocative video where he lays out the plan for Defcad.com and criticizes gun control advocates and 'collusive' 3D printing companies like Makerbot."

Blug_fred writes "The Digital Freedom Foundation is proud to announce the first celebration of Hardware Freedom Day on Saturday April 20th, 2013. While registration has opened about a month ago and early registrants will receive free banners, posters and swags as long as they register before Friday 15th, anyone who registers is of course welcome to celebrate the Day! So get your hackerspace into order, your team members ready and showcase your best 'Get Into Hacking workshop' to entice your neighbours to start. Still not lucky enough to be part of a hackerspace structure? Then use that day to meet people who will be willing to join you in the project!"

yenrabbit writes "A friend has just told me he has 80 CRT TVs, a stack of DVD players and hundreds of VCR machines, all broken and all mine free of charge. I can already think of a few awesome components I can extract (flyback transformers for high voltage contraptions and so on) and have a few ideas, such as DVD lasers, that I can build. But what else can be made from such a treasure-trove of components, and how would one go about processing such a large volume of stuff with the least amount of effort? Also, I don't have access to online shopping so I'd also like a pain free way of salvaging many simpler parts such as resistors as well." Another reader sent in a similar question: "The other day I went down to my University's property disposition center for the first time. In addition to mundane things like chairs and desks, it also had a wealth of technological devices, from old PCs and monitors to obscure medical and chemistry equipment. Honestly, I was a bit overwhelmed. I just don't know what I'd do with a old gene sequencing machine or a broken oscilloscope. Any ideas for fun projects? Or better yet, suggestions on how I can figure out which machines (or their components) are worth playing with?"
