coop0030 writes "Open source hardware company Adafruit has announced a new tiny wearable electronics platform board called the Gemma. The Gemma is a tiny, 1-inch diameter and 4-mm thick package. It's powered by an Attiny85 and programmable with an Arduino IDE over USB. There are three available I/O pins, one of which is also an analog input and two of which can do PWM output. Gemma is currently wrapping up development, but should be available soon."

Zothecula writes "Given that most real-life superheroes don't have the budget of Tony Stark or Bruce Wayne, you would assume that their gadgetry wouldn't be quite on par with what we're used to seeing in the movies. German cyber weapons hobbyist Patrick Priebe, however, has built his own working laser gauntlet... just like the one made famous by a certain Iron Man."

An anonymous reader writes "3D printing is on its way toward becoming ubiquitous. Of course, if you have such a printer and want to print something, you need raw materials — the plastic filament that's fed into the machine. It's also likely that while you're learning the ropes, you'll print a bunch of terrible attempts at objects, and end up having to throw them out. Now, Wired is reporting on a device aiming to solve both of those problems. Tyler McNaney's 'Filabot' will break down failed projects as well as many other plastic items from traditional manufacturers, turning them into a filament you can then feed through a 3D printer. 'So far the plastics that work are HDPE, LDPE, ABS, NYLON. More to come on the different types that work.' McNaney sees it as a 'closed-loop recycling system on your desk.' The Filabot's Kickstarter campaign succeeded easily in 2012, and now he and his team are getting ready to launch."

Sparrowvsrevolution writes "Over the past weekend, Defense Distributed successfully 3D-printed and tested a magazine for an AR semi-automatic rifle, loading and firing 86 rounds from the 30-round clip. That homemade chunk of curved plastic holds special significance: Between 1994 and 2004, so-called 'high capacity magazines' capable of holding more than 10 bullets were banned from sale. And a new gun control bill proposed by California Senator Dianne Feinstein in the wake of recent shootings would ban those larger ammo clips again. President Obama has also voiced support for the magazine restrictions. Defense Distributed says it hopes to preempt any high capacity magazine ban by showing how impossible it has become to prevent the creation of a simple spring-loaded box in the age of cheap 3D printing. It's posted the 3D-printable magazine blueprints on its website, Defcad.org, and gun enthusiasts have already downloaded files related to the ammo holders more than 2,200 times." Update: 01/15 23:15 GMT by T : Mea culpa; please blame my flu for mistakenly letting through that headline with "clip" where it should say "magazine." I know the difference — and I don't own any clips.

An anonymous reader writes "We all knew it was just a matter of time, now it looks like Windows RT has been Jailbroken. From the article: 'The hack, performed by Clokr, exploits a vulnerability in the Windows kernel that has existed for a long time — since before Microsoft ported Windows from x86 to ARM, in fact. Basically, the Windows kernel on your computer is configured to only execute files that meet a certain level of authentication. There are four levels: Unsigned (0), Authenticode (4), Microsoft (8), and Windows (12). On your x86 Windows system, the default setting is Unsigned — you can run anything you like. With Windows RT, the default, hard-coded setting is Microsoft (8); i.e. only apps signed by Microsoft, or parts of Windows itself, can be executed.'"

Running uClinux on an ARM Corex-M3 coupled to a Flash-based FPGA, it will be capable of receiving and transmitting from 100MHz to 1GHz. Designed to be low power, Chris has designed the radio primarily with the Amateur 2m and 70cm bands in mind. Currently in early prototyping stage, Chris intends to release the design under the TAPR Open Hardware License."

An anonymous reader writes "Niels Provos, an engineer at Google working on malware and phishing protection, is showing on YouTube how to forge knives and Viking swords. The process is absolutely fascinating and follows the steps of Viking blacksmiths from a thousand years ago. It starts by taking small bars of metal that get heated and hammered together until they become a solid piece. He then shows how to form it with the hammer, heat treat and polish it. All the videos are narrated explaining the purpose of each step. Sure beats sitting in front of the computer."

An anonymous reader writes "Joerg Sprave is at it again. This time, in order to bring in the New Year, he's got something with a bit more bang to it: a firecracker-launching slingshot. Being German, Joerg has built a slingshot that will accommodate the largest legal firecracker in that country. '2 grams of black powder in a tight cardboard "cigar" make a pretty loud bang! In order to make these bangs more spectacular, it is desirable to shoot them as high into the air as possible. A special slingshot crossbow has been designed, chambered for the strongest legal firecrackers. The weapon is a breech loader, and an integrated storm lighter allows the shooter to light the fuse when the weapon is all ready for the shot. The weapon launches the firecracker with tremendous force. The blunt object easily crashes through a moving card board box, and — equipped with a wooden tip — even goes in all the way into a block of ballistic gelatin.' His two videos are available on YouTube: part 1, part 2." This is the same gentleman who made a slingshot that launches machetes.

coop0030 writes "Wired has an article up about how Adafruit, the kit-based electronics retailer and promoter of hobbyist engineering, is aiming to teach electronics to a younger demographic. So young that they're enlisting the help of puppets. Their new online show, titled Circuit Playground, will teach the essentials of electronics and circuitry to children through kid-friendly dolls with names like Cappy the Capacitor and Hans the 555 Timer Chip. Limor 'Ladyada' Fried, Adafruit's founder and chief engineer (and 2012 Entrepreneur of the Year), will host the episodes, with her team assisting with onscreen and puppeteering duties. Episodes will premiere this March, and Fried holds hope for them to help inspire the next generation of designers and builders."

Sparrowvsrevolution writes in with a story at Forbes about Makerbot deleting gun component blueprints on Thingiverse. "In the wake of the Newtown, Connecticut shootings, the 3D-printing firm Makerbot has deleted a collection of blueprints for gun components from Thingiverse, its popular user-generated content website that hosts 3D-printable files. Though Thingiverse has long banned designs for weapons and their components in its terms of service, it rarely enforced the rule until the last few days, when the company's lawyer sent notices to users that their software models for gun parts were being purged from the site. Gun control advocates were especially concerned about the appearance of lower receivers for semi-automatic weapons that have appeared on Thingiverse. The lower receiver is the the 'body' of a gun, and its most regulated component. So 3D-printing that piece at home and attaching other parts ordered by mail might allow a lethal weapon to be obtained without any legal barriers or identification. Makerbot's move to delete those files may have been inspired in part by a group calling itself Defense Distributed, which announced its intention to create an entirely 3D-printable gun in August and planned to potentially upload it to Thingiverse. Defense Distributed says it's not deterred by Makerbot's move and will host the plans on its own site."

New submitter mihai.todor85 writes "It looks like Andrew 'bunnie' Huang has been quite busy lately, developing a nice open hardware laptop. He was even kind enough to provide all the schematics without NDA. For anybody interested in owning such a device, he says that he 'might be convinced to try a Kickstarter campaign in several months, once the design is stable and tested' if enough people are interested."

Today we're doing a live interview from 18:30 GMT until 20:30 GMT with long time contributor Luke Leighton of Rhombus Tech. An advocate of Free Software, he's been round the loop that many are now also exploring: looking for mass-volume Factories in China and ARM processor manufacturers that are truly friendly toward Free Software (clue: there aren't any). He's currently working on the first card for the EOMA-68 modular computer card specification based around the Allwinner A10, helping the KDE Plasma Active Team with their upcoming Vivaldi Tablet, and even working to build devices around a new embedded processor with the goal of gaining the FSF's Hardware Endorsement. Ask him anything. (It's no secret that he's a Slashdot reader, so expect answers from lkcl.)

coop0030 writes "Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware: pre PS/2 and definitely pre-USB. That means you can't just plug the keyboard into a PS/2 port (even though it looks similar). There is no existing adapters for sale, and no code out there for getting these working, so we spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between."

lkcl writes about his effort to go further than others have, and actually have a processor designed for Free Software manufactured: "A new processor is being put together — one that is FSF Endorseable, contains no proprietary hardware engines, yet an 800MHz 8-core version would, at 38 GFLOPS, be powerful enough on raw GFLOPS performance figures to take on the 3ghz AMD Phenom II x4 940, the 3GHz Intel i7 920 and other respectable mid-range 100 Watt CPUs. The difference is: power consumption in 40nm for an 8-core version would be under 3 watts. The core design has been proven in 65nm, and is based on a hybrid approach, with its general-purpose instruction set being designed from the ground up to help accelerate 3D Graphics and Video Encode and Decode, an 8-core 800mhz version would be capable of 1080p30 H.264 decode, and have peak 3D rates of 320 million triangles/sec and a peak fill rate of 1600 million pixels/sec. The unusual step in the processor world is being taken to solicit input from the Free Software Community at large before going ahead with putting the chip together. So have at it: if given carte blanche, what interfaces and what features would you like an FSF-Endorseable mass-volume processor to have? (Please don't say 'DRM' or 'built-in spyware')." There's some discussion on arm-netbook. This is the guy behind the first EOMA-68 card (currently nearing production). As a heads ups, we'll be interviewing him in a live style similarly to Woz (although intentionally this time) next Tuesday.

An anonymous reader writes "Quoting liliputing: 'PengPod plans to start shipping 7 and 10 inch tablets with support for Linux as well as Google Android in January. The company, founded by Neal Peacock, has been raising money to help support software development for the tablets — and Peacock just wrote in to let us know the project has surpassed its initial $49,000 fundraising goal. In other words, the campaign will be fully funded and backers that pledged $120 or more should get their tablets starting in January if all goes according to plan.'" And, unlike many ARM SoCs, the kernel for the Allwinner A10 powering it is developed openly.

slashchuck writes "One of the drawbacks of Google's Nexus 4 was its lack of support for 4G LTE. Now comes a report from AnandTech that it's possible to enable partial LTE support on the device. It seems that a simple software update can allow the Nexus 4 smartphone to run on LTE Band 4. All users have to do is dial *#*#4636#*#* (INFO) or launch the Phone Info app. After that, choosing to connect to AWS networks should allow the Nexus 4 to run on LTE networks on Band 4. The AnandTech report states explicitly that the LG Nexus 4 only works on LTE Band 4, on 1700/2100MHz frequencies, and supports bandwidths of 5,10, and 20MHz."
