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."

Japanese and Swiss Watchmakers Scoff At Smartwatches 399

jfruh (300774) writes "With rumors swirling about Apple entering the wearable space with an iWatch, you'd think that the Japanese and Swiss companies that have dominated high-end watchmaking for more than a century would be scrambling to catch up. But there were virtually no smartwatches on display at the Baselworld trade fair, and the watchmaking giants had no plans to produce any. Company representatives seemed sure that people in practice would be uninterested in constantly recharging their watches and downloading software updates just to tell time."

Man Builds DIY Cellphone Using Raspberry Pi 83

Photographer and software engineer Dave Hunt has posted an article about his most recent project: a DIY cellphone based on a Raspberry Pi (he calls it a PiPhone). It has a touchscreen dialing interface for making calls, and it's built with off-the-shelf components. The total bill of materials clocks in at about $158: $40 for the rPi, $35 for the 320x240 touchscreen, $15 for the LiPo battery, $48 for the GSM module, and about $20 for miscellaneous other minor parts. Hunt says, '[The GSM/GPRS module] allow us to send standard AT commands to it to make calls, hang up, send texts, data etc. Overall a very clever module. Towards the bottom of the white PCB, you can see the SIM Card, which allows the module to associate with my local GSM network, and it’s using a regular prepaid SIM card, bought in my local phone store for €10. Below the GSM module, you can see the on.off switch and a DC-DC converter, which converts the 3.7volts from the LiPoly battery to 5volts needed by everything else.' He points out that the phone is not terribly practical, but it's a neat project. Hunt has done several others, including turning the Raspberry Pi into a controller for time-lapse photography. He'll be publishing the code he wrote for the PiPhone next week.

Google's Business Plan For Nest: Selling Your Data To Utility Companies 167

jfruh (300774) writes "Google spent $3.2 billion on Nest. How is it going to make its money back selling high-end electronic thermostats at $250 a pop? Well, keep in mind that Google is a company that makes its money off information, not hardware. In fact, Nest is developing a healthy revenue stream in which it sells aggregated user information to utility companies, to help them more efficiently plan their electricity-generation scheduling. The subscriptions net Google somewhere in the range of $40 per user per year."

DIY Wearable Pi With Near-Eye Video Glasses 59

coop0030 (263345) writes "Noe & Pedro Ruiz at Adafruit have created a pair of open source near-eye video glasses combined with a Raspberry Pi. Their 3D Printed design turns a pair of 'private display glasses' into a "google glass"-like form factor. It easily clips to your prescription glasses, and can display any kind of device with Composite Video like a Raspberry Pi. They have a video demonstrating the glasses, a tutorial on how to build them, along with the 3d files required to print it out."

$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand 288

An anonymous reader writes "A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' an open source hand which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."

Cody Wilson Interview at Reason: Happiness Is a 3D Printed Gun 207

An anonymous reader writes "Cody Wilson details his conflict with the State Department over 3-D printable guns in this new interview with ReasonTV. In this video, he discusses how 3-D printing will render gun control laws obsolete and unenforceable; why Dark Wallet, his new crypto-currency, is much more subversive than Bitcoin; his legal defense, headed by Alan Gura (attorney in District of Columbia v. Heller and McDonald v. Chicago); and his forthcoming book about anarchy and the future."

For $20, Build a VR Headset For Your Smartphone 50

An anonymous reader writes "Not everyone can drop a few hundred dollars on a VR headset, but that doesn't mean they can't experience VR! For those with the time and a bit of handiwork skill, this DIY guide from guest writer Ohaple will show you how to make a smartphone-based VR headset for as little as $20. Along the way, you'll learn the hardware and software basics of a VR headset." This project screams for a ready-made commercial version; does anyone know of existing purpose-built headgear? As one of the comments on the linked tutorial says, Poppy seems close, but lacks an LED for tracking.

Ask Slashdot: Which Router Firmware For Bandwidth Management? 104

First time accepted submitter DeathByLlama (2813725) writes "Years ago I made the switch from DD-WRT to Tomato firmware for my Linksys router. I lost a couple features, but gained one of the best QoS and bandwidth management systems I have seen on a router to date. Admins can see graphs of current and historical bandwidth usage by IP, set minimum and maximum bandwidth limits by IP range, setup QoS rules, and see and filter graphs and lists of current connections by usage, class or source/destination — all from an elegantly designed GUI. This has allowed me to easily and intelligently allocate and adjust my network's bandwidth; when there is a problem, I can see where it's coming from and create rules around it. I'm currently using the Toastman's VPN Tomato firmware, which has about everything that I would want, except for one key thing: support for ARM-based routers (only Broadcom is supported). I have seen other firmware projects being actively developed in the last few years, so in picking a new 802.11ac router, I need to decide whether Tomato support is a deal-breaker. With solid bandwidth management as a priority, what firmware would you recommend? Stock Asuswrt? Asuswrt-Merlin? OpenWRT? DD-WRT? Tomato? _____?"
