MIT Researcher Works Toward Robots That Assemble Themselves In an Oven 20

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."

Ask Slashdot: What Inspired You To Start Hacking? 153

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?"

Tiniest Linux COM Yet? 76

DeviceGuru writes: "An open-spec COM that runs OpenWRT Linux on a MIPS-based Ralink RT5350 SoC has won its Indiegogo funding. The $20, IoT-focused VoCore measures 25 x 25mm. How low can you go? Tiny computer-on-modules (COMs) for Internet of Things (IoT) applications are popping up everywhere, with recent, Linux-ready entries including Intel's Atom or Quark-based Edison, Ingenic's MIPS/Xburst-based Newton, Acme Systems's ARM9/SAM9G25 based Arrietta G25, and SolidRun's quad-core i.MX6-based MicroSOM. Now, an unnamed Chinese startup has raised over six times its $6,000 Indiegogo funding goal for what could be the smallest, cheapest Linux COM yet."

'Curiosity' Lead Engineer Suggests Printing Humans On Other Planets 323

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."

Google Glass and the Future of Wearable Gaming 39

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."

Servo Stock 3D Printer Brings Closed-Loop Control To Reprap 56

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.

Google Rumored To Be Making 3D-Scanning Tablets 55

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?

LegoTechno -- Making Music With Lego Bricks, Python, OpenCV and a Groovebox 5

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.)"

Unlock Your Android Phone With Open Source Wearable NFC 81

coop0030 (263345) writes "Becky Stern at Adafruit has created a guide on how to create an open source NFC ring or other wearable to mod and unlock your Android phone. From the tutorial: 'Unlock your phone by just picking it up! No more pesky password or gesture PIN, just scan an NFC tag! This guide covers creating an NFC ring, putting an NFC tag in your nail polish, modding your Android installation to read tags from the lockscreen, and creating an automation toolchain to unlock the phone when the desired tag is scanned.' There is also a video that demonstrates how it works."

Autodesk Unveils 3d Printer As It Aims To Become Industry's Android 85

Hugh Pickens DOT Com (2995471) writes "BBC reports that Autodesk — the leading 3D modelling software-maker — is going into hardware with its own 3D printer and in addition to selling the machine, Autodesk will also allow other manufacturers to make their own versions of the printer or power their own models off its software at no cost. 'The printer is a bona fide attempt to prove the interoperability and open source nature of Autodesk's platform,' says Pete Basiliere. 'And by sharing its design we could see a second wave of small start-ups creating stereolithography machines just as the makers did when the early material extrusion patents expired.' Chief executive Carl Bass likened the new printer to Google's first Nexus smartphone, a product meant to inspire other manufacturers to install Android on their handsets rather than become a bestseller itself. In Autodesk's case the idea is to drive the adoption of its new Spark software, a product it likens to being an 'operating system for 3D-printing'. Although Autodesk is giving away both Spark and the printer's design, the company should still profit because the move would drive demand for the firm's other products. 'If 3D printing succeeds we succeed, because the only way you can print is if you have a 3D model, and our customers are the largest makers of 3D models in the world.'

Instead of the extrusion technique most commonly used by existing budget printers, Autodesk's printer uses a laser to harden liquid plastic to create the objects delivering smoother, more complex and more detailed objects. 'We're making a printer that, rather than just being able to load in proprietary materials, you can load in any material you want. You can formulate your own polymers and experiment with those. That's an important next step because we think material science is a breakthrough that has to happen to make [the industry] go from low-volume 3D-printed stuff to where it really starts changing manufacturing.' Bass said, its printer is targeted at more professional users–for creating small objects like medical devices or jewelry–and will likely end up closer to the $5,000 range, though exact pricing has not been set."

OpenRISC Gains Atomic Operations and Multicore Support 77

An anonymous reader writes "You might recall the Debian port that is coming to OpenRISC (which is by the way making good progress with 5000 packages building) — Olof, a developer on the OpenRISC project, recently posted a lengthy status update about what's going on with OpenRISC. A few highlights are upstreamed binutils support, multicore becoming a thing, atomic operations, and a new build system for System-on-Chips."

A 32-bit Development System For $2 138

An anonymous reader writes "If you are too cheap to buy a $20 Arduino or too elitist to not have at least a 32-bit processor, Dr. Dobb's shows you how to take a $2 chip, put it on a breadboard with a TTL serial (or USB) cable, and be up and running with a 32-bit C/C++ system. Even if you have to buy the breadboard and the cable, it is comparable in price to an Arduino and much more capable. The Mbed libraries (optional) make it as easy to use a 'duino, too."

First Arrest In Japan For 3D-Printed Guns 274

PuceBaboon (469044) writes "Earlier today (Thursday), police in Kawasaki, Japan, arrested a man for violation of the firearms control law. He was apparently in possession of five, 3D-printed handguns, two of which were reportedly capable of firing normal rounds (although no actual bullets were found). The suspect was arrested after releasing video of the guns online. Japan has very strict gun control laws and, whether or not the suspect actually appeared in the alleged video, he may just have signed himself up for some serious porridge."

Samsung 'Smart' Camera Easily Hackable 62

An anonymous reader writes "The op-co.de blog has a post about the incredibly poor job Samsung did securing its new NX300 'smart camera.' One of the camera's primary features is that it can join Wi-Fi networks — this lets it upload photos, but it also lets you use your smartphone to access the photos on the camera directly. You can also connect with NFC. Unfortunately, the way they set it up is extremely insecure. First, there's an NFC tag that tells the camera where to download the app, and also the name of the access point set up by the camera. 'The tag is writable, so a malicious user can easily 'hack' your camera by rewriting its tag to download some evil app, or to open nasty links in your web browser, merely by touching it with an NFC-enabled smartphone.' Things aren't much better with Wi-Fi — a simple port scan reveals that the camera is running an unprotected X server (running Enlightenment). When the camera checks for new firmware, it helpfully reports your physical location. Its software also sets up unencrypted access points."

Can the Lix 3D Printing Pen Actually Work? 90

szczys (3402149) writes "Brian Benchoff used science and math to prove that the performance shown in the Lix Kickstarter video is questionable at best. Check his evidence and see if he's done an appropriate job of debunking the functionality presented." From the Hackaday post: "While we know the video is an outright misrepresentation of what any USB 3 powered device can do, We can’t figure out if the Lix is a viable product. We’re turning to you. Can you figure out if the Lix pen actually works? All we know is the Lix pen has a 4.5 Watt power supply from a USB 3 port. It’s possible for a USB 3 powered 3D printing pen to work, albeit slowly, but the engineering is difficult and we don’t know if the Lix team has the chops."
