An anonymous reader writes "An article at Wired shows just how close we are to a 3-D printed car. Jim Kor's 'Urbee 2' design is a lightweight teardrop shape with three wheels. The engine, chassis, and wheels aren't printed, of course, but much of the car is formed layer-by-layer out of ABS plastic. It takes about 2,500 hours of printer time to create the whole thing. Assembly is easier, though, since many different parts can be consolidated into just a few. 'To negotiate the inevitable obstacles presented by a potentially incredulous NHSTA and DOT, the answer is easy. "In many states and many countries, Urbee will be technically registered as a motorcycle," Kor says. It makes sense. With three wheels and a curb weight of less than 1,200 pounds, it's more motorcycle than passenger car. No matter what, the bumpers will be just as strong as their sheet-metal equivalents. "We're planning on making a matrix that will be stronger than FDM," says Kor. He admits that yes, "There is a danger in breaking one piece and have to recreate the whole thing." The safety decisions that'll determine the car's construction lie ahead. Kor and his team have been tweaking the safety by using crash simulation software, but the full spectrum of testing will have to wait for an influx of investment cash.'"

derGoldstein writes "We've seen some very impressive aerobatics performed by quadrocopters before, but this is getting ridiculous. Robohub points to the latest advancement from the Flying Machine Arena, which developed algorithms that allow quadrocopters to juggle an inverted pendulum. One of the researchers working on it said, 'We started off with some back-of-the-envelope calculations, wondering whether it would even be physically possible to throw and catch a pendulum. This told us that achieving this maneuver would really push the dynamic capabilities of the system. As it turned out, it is probably the most challenging task we've had our quadrocopters do. With significantly less than one second to measure the pendulum flight and get the catching vehicle in place, it's the combination of mathematical models with real-time trajectory generation, optimal control, and learning from previous iterations that allowed us to implement this.'"

Several readers sent word of a new addition to the 3-D printing industry. Most 3-D printers are roughly the size of regular printers, and require design files on the computer to guide the extruder. Now there's a much smaller and much simpler alternative: the 3Doodler pen, which lets you draw 3-D objects by hand. The people making the pen set up a Kickstarter project yesterday with a $30,000 goal. They reached that within hours, and now have pledges exceeding $800,000. "The 3Doodler pen is 180mm by 24mm. The pen weighs less than 200 grams or 7 ounces (the weight of a typical apple), although the exact weight will depend on the final shell specifications once in production. And we are using a universal power supply, so provided you have the correct adapter for your country, 3Doodler will work just fine on 110v or 240v. ... While the plastic extruded from 3Doodler is safe to touch once it has left the pen, the pen itself has a metal tip that can get as hot as 270C." The pen uses the same ABS/PLA plastic as most 3-D printers, and they're planning to host stencil designs on their website so that users have patterns to sketch from.

An anonymous reader writes "We've watched patents slow down the smartphone and tablet markets. We've seen patent claims thrown against Linux, Android, and countless other software projects. Now, as 3-D printing becomes more capable and more affordable, it seems a number of patents threaten to do the same to the hobbyist and tinkerer crowd. Wired has highlighted some of the most dangerous ones, including: a patent on soluble print materials that support a structure while it's being printed; a ridiculously broad patent on distributed rapid prototyping, which could affect "every 3-D printing service that has launched in the past few years"; and an 18-year-old patent on 3-D printing using a powder and a binding material, held by MIT."

jfruh writes "The Kindle Fire HD is in theory a powerful device at a reasonable price — but its Android-based OS is so oriented towards Amazon's ecosystem that it can be tricky to unlock its full potential. Still, with a little savvy you can get underneath the covers, improving battery life, getting full access to cameras and other devices, and even listening to music you've purchased through iTunes."

Wired reports that the 3-D printed AR-15 magazine from Defense Distributed we mentioned a few weeks back has been improved through design, and is now robust enough to last through firing (at least) several hundred rounds, rather than fewer than a hundred as in the previous iteration. CNET says the video demonstration on YouTube was first yanked, then restored, but as of now seems to have been yanked again.

New submitter Zeussy writes "While looking around Thingiverse for something to 3D-print, I found this awesome public domain prosthetic hand designed for a 5-year-old child called Liam, who was born without any fingers on his right hand. The design is based on parts either 3D-printed or bought from your local hardware store. It's body powered via cables and bungees; see it in action in this video. They are currently running a Fundly Fundraiser."

crankyspice writes "Having recently picked up the Erector set I've wanted since I was a kid, I quickly found myself wanting to plunge deeper into makerspace by adding more sophisticated electronics to moving devices (rovers, maybe eventually flying bots). My first instinct was Arduino (maybe because of brand recognition?), but that got me thinking — what's the 'best' platform out there (most flexible)? Arduino with its myriad options (Nano, Mega, Uno, Mini)? PICAXE? BASIC Stamp? Raspberry Pi? (The latter seems like it would easily be the most flexible, but at greater cost in terms of weight and complexity.) I'm a hobbyist programmer, having learned C and C++ in college and recently re-learning Java (took and passed the Oracle Certified Professional exam, FWIW)..."

MikeChino writes "Instructables member Patrik has successfully transformed an old HP5150 inkjet printer into a DIY bioprinter. To do this he removed the plastic covers and panels and rewired the paper handling mechanism. Then he prepped ink cartridges to be able to handle biological materials by opening the lid, removing the ink, and washing it out with deionized water. For his first experiment, he printed a simple solution of arabinose onto filter paper."

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."
