First time accepted submitter afeeney (719690) writes 'The Centre for Art and Media in Karlsruhe, Germany, is displaying an ear grown from DNA contributed by a relative of artist Vincent Van Gogh. The Center said artist Diemut Strebe made the replica using living cells from Lieuwe van Gogh, the great-great-grandson of Vincent’s brother Theo. Using a 3D-printer, the cells were shaped to resemble the ear that Vincent van Gogh is said to have cut off during a psychotic episode in 1888. “I use science basically like a type of brush, like Vincent used paint,” Strebe told The Associated Press. Historians argue about whether Van Gogh cut off his own ear and if so, why, but it remains one of the most famous acts of self-mutilation in the Western world.'

Lucas123 (935744) writes 'Ford has been using 3D printing for rapid prototyping since the mid-1980s, but in recent years it has ramped up its efforts adding new machines and materials. A tour of the facility revealed four different methods of 3D printing being used to prototype parts. For example, Ford uses Nylon 11 and laser sintering to make parts that can be retrofitted to working vehicles and tested over thousands of miles. The center also uses binder jet printing to form molds for metal prototypes by laying down layers of sand that are then epoxied together. Just one of its five 3D prototyping centers churns out more than 20,000 parts a year. Today, Ford could not meet new vehicle deadlines without 3D printing.'

Nerval's Lobster writes: 'Following up on news that ActiveLink is building heavy-duty exoskeletons for work in nuclear plants, IEEE Spectrum reports that MIT researchers are experimenting with Supernumerary Robotic Limbs (SRLs) that attach to either the shoulder or waist. The SRLs are capable of lifting objects and bracing against solid surfaces. From the article: "The SRL watches what you're doing with your arms to decide how to move. It does that by monitoring two inertial measurement units (IMUs) that the user wears on the wrists. A third IMU sits at the base of the robot's shoulder mount, to track the overall orientation and motion of the SRL." In the future, we will all have the ability to become Doctor Octopus (minus two robo-limbs, of course).'

The Fuel 3-D website has a blurb that says, "The world’s first handheld point-and-shoot, full color 3D scanner. Our planned list price is $1500 but by placing your advanced order now you pay only $1,250. Fire up your creativity!" We've thought about getting a 3-D scanner ever since we first messed with a 3-D printer, but we've thought more about something in the sub-$300 price range than in $1000+ territory. But that's just us. There is no doubt a healthy market for 3-D scanners to use in commercial applications where $1250 (or even $1500) is hardly worth noticing. Ah, well. Maybe we need to look at the The DAVID website which describes their device as an "Incredibly Low-Cost 3D Scanner for Everyone!" Their 3-D starter kit is only $529 from a randomly-selected U.S. reseller, which isn't too bad compared to the alternatives. But waiting for prices in this market niche to come down is another possibility, and it's one a whole lot of individuals -- including us -- and smaller companies will probably choose.

Lucas123 (935744) writes "Cody Wilson, the 26-year-old former law school student who published plans for printing 3D guns online, disputed claims by universities and government agencies that his thermoplastic gun design is unsafe. Wilson claims the agencies that tested the guns did not build them to spec. In a Q&A with Computerworld, he also addressed why he's continuing to press regulatory agencies to allow him to offer the plans again for upload after being ordered to take them down, saying it's less about the Second Amendment and more about the implications of open source and the digital age. "If you want to talk about rights, what does it mean to respect a civil liberty or civil right? Well, it means you understand there are social costs in having that right; that's why it deserves protection in the first place," he said. Wilson is also planning to release other gun-related project, though not necessarily a CAD design."

An anonymous reader writes "Nick Pitton, the developer behind the Spirited Away Boiler Room VR experience, has released his second project: the bus stop scene from Studio Ghibli's famous movie My Neighbor Totoro, once again in virtual reality for the Oculus Rift. Pittom 'hand-painted' the textures in Photoshop to recreated the painted-background feel of the movie. For the characters (Totoro and the Catbus) he used a cel-shaded approached to approximate the animated look from the movie. For his next project, he plans to recreate the ship and characters from the acclaimed anime Cowboy Bebop."

TechCrunch is among the many outlets which carry news (based on a release from MIT professor Daniela Rus) of robots that take advantage of materials engineered to change shape with the application of heat. With carefully planned creases and slits "printed" into flat sheets of plastic, heat-induced deformation can be channeled to create complex three-dimentional shapes, something between origami and Shrinky-Dinks. The creases can also be used to create moving parts in the finished product, and -- as with papercraft -- folding, overlapping and other techniques can increase the stiffness or otherwise give useful properties to the robot bodies formed. From the article: "This project could also produce a variable resistor by opening or closing an electric component and even create metallic muscles that contract when heated or current is applied. It’s obviously still in very early stages right now but Rus and her team will exhibit the technology at the IEEE International Conference on Robotics and Automation this year and maybe, one day, our cake-like robotic servants will rise up and bake us."

Lucas123 (935744) writes "It appears an Idaho-based company that created prototype panels for constructing roads that (among other features) gather solar power, will be going into production after it exceeded its crowdfunding goal of $1M. ... Solar Roadways' Indiegogo project has already exceeded $1.6 million. The hexagonal-shaped solar panels consist of four layers, including photovoltaic cells, LED lights, an electronic support structure (circuit board) and a base layer made of recyclable materials. The panels plug together to form circuits that can then use LED lights to create any number of traffic patterns, as well as issue lighted warnings for drivers. The panels also have the ability to melt snow and ice. Along with the crowdfunding money, Solar Roadways has received federal grant money for development."

An anonymous reader writes "What got you into hacking? This is a question that Jennifer Steffen, IOActive CEO, often asks hackers she meets on conferences around the world. More often than not, the answer is movies: War Games, Hackers, The Matrix, and so on. But today, it is the real life hacking that is inspiring the movies of tomorrow. 'Hackers are doing epic stuff,' she says, and they are now inspiring movies and comics. So, what got you started? And what makes a good hacker today?"

An anonymous reader writes "The SparkFun team took a tour of a factory in China that manufactures LEDs. They took lots of pictures showing the parts that go into the LEDs, the machines used to build them, and the people operating the machines. There's a surprising amount of manual labor involved with making LEDs. Quoting: 'As shipped on the paper sheets, the LED dies are too close together to manipulate. There is a mechanical machine ... that spreads the dies out and sticks them to a film of weak adhesive. This film is suspended above the lead frames ... Using a microscope, the worker manually aligns the die, and, with a pair of tweezers, pokes the die down into the lead frame. The adhesive in the lead frame wins (is more sticky), and the worker quickly moves to the next die. We were told they can align over 80 per minute or about 40,000 per day.'"

They say, 'without additional expertise and the right type of ammunition, anyone attempting to fire one would probably maim or even kill themselves.'"

Jason Koebler (3528235) writes "Adam Steltzner, the lead engineer on the NASA JPL's Curiosity rover mission, believes that to send humans to distant planets, we may need to do one of two things: look for ways to game space-time—traveling through wormholes and whatnot—or rethink the fundamental idea of 'ourselves.' 'Our best bet for space exploration could be printing humans, organically, on another planet,' said Steltzner."

An anonymous reader writes "Google Glass is now becoming more widely available, but developers are only just starting to tap into the augmented reality specs' potential for gaming. A new report looks at some of the early experiments with the tech — leading the charge is indie developer Mind Pirate, the first studio to release a mobile game simultaneously on iPhone and Google Glass. But will others get on board? Will the explosion in popularity of virtual reality headsets help or hinder it? It's still a wild wild west.

'The potential of wearables will only be realized through thoughtful integration of hardware and software,' says Mind Pirate CEO Shawn Hardin. Right now, 'much of the mature infrastructure of the mobile arena' is missing in the world of wearables. The 'myriad of unique sensor and hardware configurations atop increasingly diverse operating systems' makes it particularly difficult for developers to get started."

Affordable 3-D printing is still young; just a few years ago, it would have been nearly impossible to have an arbitrary three-dimensional piece of plastic (or resin, or sometimes metal) created from a software description in a box that fits on your desk. But in the several years the printing of *things* has moved fromquaint, quixotic, futzing-about hobby into something that works (fairly) reliably in ever more garages, schools, and hackerspaces, it's gotten good enough that you can now download and print quite a few objects that are available for download, or scan small items to replicate, or scan your friends to print out as statuettes. However, for the most part, these printed pieces are static, and finished. With care, you can print things like a chain, or even a ball joint, but you're still limited mostly to one basic material at a time. (Printing with multiple colors is getting easier, though.) If you want to print a flashlight or a robot, you'll need to add wires and other circuitry as a separate step. That's what the folks at Rabbit Proto (get it?) are trying to change. With the system they're working on, a filament printer is used to fabricate the object itself, but at the same time, both capacitive and conductive features can be baked -- or rather printed -- right in, with a separate print head. We talked with Alexandre Jais and Manal Dia of Rabbit Proto about how the system works, and why you might want to use it. (Alternate video link.)

A limitation of current (affordable) 3D printers is their use of open loop controllers and stepper motors which limits reliability (drove the motor too quickly and skipped a step? Your model is ruined) and precision (~300 steps per revolution). A new project, Servo Stock instead uses cheap RC Servomotors combined with Hall Effect sensors, using a closed-loop controller to precisely position the extruder. The Servo Stock is derived from the delta robot Reprap Rostock (which is pretty cool even with stepper motors). The sensors give a resolution of 4096 ticks per rotation, and the controller can currently position the motors to within +/-2 ticks. They've also simplified the printer electronics by driving as much as possible from the controlling computer using Bowler, a new communication protocol for machine control. The Servo Stock also includes sensors for the hot end, presumably to be used to control the filament feed rate and temperature. The hardware models are fully parametric, allowing reasonably straightforward scaling of the design. Source for the hardware, firmware, and software is available.

According to The Wall Street Journal, Google may be planning to commoditze 3-D scanning by building the tech of its Project Tango project (essentially, thus far, a phone-sized handheld with 3-D sensing capabilities) into tablets. The Register speculates: "Given that Google has already announced the Project Tango smartphone, it seems likely that it would extend the technology to tablets, and the seven-inch form factor would tie in nicely with the existing Nexus 7 design. ...Google is hoping that developers can build applications to use the scanning capabilities of the Tango hardware. Suggested topics include providing guides for visually impaired people, building gaming maps based on actual rooms, and possibly augmenting Google Maps with interior details – Street View becoming Home View perhaps?" Setting aside what brand it might bear, how would you employ a portable 3-D scanner?

bauhausinteraction writes "A team from the Bauhaus-University and Native Instruments Developers built and programmed a fully functional interactive Lego Sequencer / Tangible Groove Machine that sends control data to the Maschine drum sequencer to make music. The thing was built within 24 hours as an unofficial weekend collaboration between bauhausinteraction and NI at the MidiHack 2014 in Stockholm. A standard webcam is mounted underneath the baseplate. The image is processed by a Python Script using the OpenCV Library to track the bricks. The tricky bit was to not track the user's hand, but we succeeded at that as well.

The information about brick color, position, and orientation is derived from the image and then converted into OpenSoundControl (OSC) messages. Those are sent over a network connection to a computer running Native Instruments Maschine to play back the sounds. Of course, this would work with other sound generators as well, since the whole thing simply spits out OSC-Messages and MIDI — but hey: if the guys from Native are there, you'd better use their Maschine stuff. Being real Masterbuilders, of course we used only unmodified, standard Lego Parts and no Kragle* for the construction. (*see the Lego Movie for reference.)"
