Peter Hoddie Talks About His Internet of Things Construction Kit (Video)

Roblimo posted 6 hours ago | from the everything-you-own-must-now-connect-to-the-internet dept.

Programming 45

You remember Peter Hoddie, right? He was one of the original QuickTime developers at Apple. He left in 2002 to help found a startup called Kinoma, which started life developing multimedia players and browsers for mobile devices. Kinoma was acquired in 2011 by Marvell Semiconductor, whose management kept it as a separate entity.

The latest creation from Peter and his crew is the 'Kinoma Create,' AKA the 'JavaScript-Powered Internet of Things Construction Kit.' With it, they say, you can 'quickly and easily create personal projects, consumer electronics, and Internet of Things prototypes.' EE Times mentioned it in March, and they're not the only ones to notice this product. Quite a few developers and companies are jumping on the 'Internet of Things' bandwagon, so there may be a decent -- and growing -- market for something like this. (Alternate Video Link)

Grad Student Rigs Cheap Alternative To $1,000 Air Purifiers In Smoggy China

Hardware Hacking 156

An anonymous reader writes "University of Virginia grad student Thomas Talhelm was living in Beijing on a Fulbright Scholarship during the winter of 2012-13, when air pollution was so bad scientists likened it to a nuclear winter. Those who could afford it were resorting to an expensive solution: air filters costing up to $1,000. Talhem built his own on the cheap, getting comparable particulate count results, and has started a company that both markets the product to middle class Chinese and shows others how to DIY."

NASA's JPL Develops Multi-Metal 3D Printing Process

NASA 29

yyzmcleod (1534129) writes The technology to 3D print a single part from multiple materials has been around for years, but only for polymer-based additive manufacturing processes. For metals, jobs are typically confined to a single powdered base metal or alloy per object. However, researchers at NASA's Jet Propulsion Laboratory say they have developed a 3D printing technique that allows for print jobs to transition from one metal to another in a single object. From the article: In JPL’s technique, the build material’s composition is gradually transitioned as the print progresses. For example, the powdered build material might contain 97 percent titanium alloy and 3 percent stainless steel at the beginning of the transition. Then, in 1 percent increments between layers, the gradient progresses to 97 percent stainless steel and 3 percent Ti alloy by some defined point in the overall 3D printing process.

Raspberry Pi-Compatible Development Board Released

Hardware Hacking 47

kodiaktau writes: Hardkernel has released a new Raspberry Pi-compatible development board based on the Samsung Exynos SoC. The board is smaller than a typical Pi, keeping basic HDMI, USB and CSI interfaces. It also has a 26-pin expansion board with more GPIO available, though it lacks an Ethernet jack. Initial prices as estimated around $30. The article makes the interesting point that this and other devices are marketed as "Raspberry Pi-compatible." The Raspberry Pi Foundation may run into name retention issues (similar to the ones Arduino had) as related hardware piggybacks on its success.

A Look At the Firepick Delta Circuit Board Assembler (Video)

Roblimo posted 2 days ago | from the components-get-tinier-every-year dept.

43

From the Firepick website: 'We are developing a really cool robotic machine that is capable of assembling electronic circuit boards (it also 3D prints, and does some other stuff!). It uses a vacuum nozzle to pick really tiny resistors and computer chips up, and place them down very carefully on a printed circuit board.' There are lots of companies here and in China that will happily place and solder components on your printed circuit board, but hardly any that will do a one-off prototype or a small quantity. And the components have gotten small enough that this is really a job for a robot (or at least a Waldo), not human fingers. || There are obviously other devices on the market that do this, but Firepick Delta creator Neil Jansen says they are far too expensive for small companies, let alone individual makers.

The Firepick Delta Hackaday page talks about a $300 price for this machine. That may be too optimistic, but even if it ends up costing two or three times that amount, that's still a huge step forward for small-time inventors and custom manufacturers who need to populate just a few circuit boards, not thousands. They have a Haxlr8r pitch video, and have been noticed by TechCrunch, 3DPrintBoard.com, and Adafruit, just to name a few. Kickstarter? Not yet. Maybe next year. Open source? Totally, complete with GitHub repository. And they were at OSCON 2014, which is where Timothy found them. (Alternate Video Link)

3-D Printing Comes To Amazon

Soulskill posted 2 days ago | from the world-goes-plastic dept.

Businesses 62

An anonymous reader writes Promising "an appstore for the physical world," Amazon has just unveiled their new online market for products created using a 3-D printer. "Customization gives customers the power to remix their world," explains the co-founder of Mixee Labs (an Amazon partner), "and we want to change the way people shop online." Amazon's ability to sell you things before they've even been built is currently limited mostly to novelties like iPhone cases, jewelry, and bobbleheads that look like you. But this could be the beginning of mainstream 3D printing.

Ask Slashdot: Open Hardware/Software-Based Security Token?

timothy posted 2 days ago | from the you-could-use-postcards-scanned-by-an-arduino dept.

Security 110

Qbertino (265505) writes I've been musing about a security setup to allow my coworkers/users access to files from the outside. I want security to be a little safer than pure key- or password-based SSH access, and some super-expensive RSA Token setup is out of question. I've been wondering whether there are any feasible and working FOSS and open hardware-based security token generator projects out there. It'd be best with ready-made server-side scripts/daemons. Perhaps something Arduino or Raspberry Pi based? Has anybody tried something like this? What are your experiences? What do you use? How would you attempt an open hardware FOSS solution to this problem?

Build Your Own Gatling Rubber Band Machine Gun

Toys 39

New submitter melarky (3767369) writes This is a fun weekend project that most nerds will appreciate. Step by step instructions and also a handy video will make the construction of this project fast and easy. I have seen lots of plans for sale (or actual guns/kits for sale), but couldn't seem to find any plans for free. I played around with a few different designs (even cut my first few on a homemade CNC machine) and finally landed on this design. I made the guide more accessible to the general public (no need for a CNC machine here), so if you've ever dreamed of ending friendships because of hundreds of rubber band welts, now's your chance! We'd like to see your home-made projects, too.

A Router-Based Dev Board That Isn't a Router

timothy posted 4 days ago | from the hook-it-to-anything dept.

Networking 53

An anonymous reader writes with a link to an intriguing device highlighted at Hackaday (it's an Indiegogo project, too, if it excites you $90 worth, and seems well on its way to meeting its modest goal): The DPT Board is something that may be of interest to anyone looking to hack up a router for their own connected project or IoT implementation: hardware based on a fairly standard router, loaded up with OpenWRT, with a ton of I/O to connect to anything.

It's called the DPT Board, and it's basically an hugely improved version of the off-the-shelf routers you can pick up through the usual channels. On board are 20 GPIOs, USB host, 16MB Flash, 64MB RAM, two Ethernet ports, on-board 802.11n and a USB host port. This small system on board is pre-installed with OpenWRT, making it relatively easy to connect this small router-like device to LED strips, sensors, or whatever other project you have in mind.

Two South African Cancer Patients Receive 3D Printed Titanium Jaw Implants

timothy posted 5 days ago | from the ok-but-they-did-already-need-them dept.

Medicine 71

jigmypig (3675225) writes "Two patients in South Africa that have had their lives and more specifically their jaws severely affected by cancer, have just received 3D printed jaw implants. The jaws were 3D printed using a laser sintering process that melts powdered titanium, one layer at a time. The process saves a ton of money, and unlike traditional manufacturing of titanium jaws, it doesn't waste any materials. Traditional manufacturing wastes up to 80% of the titanium block used in the process, whereas with 3D printing there is little to no waste at all. This new process also allows for a fully customizable solution. The models are drawn up in CAD software, and then printed out to precisely fit the patient."

Household Robot Jibo Nets Over $1 Million On Indiegogo

Communications 61

mikejuk (1801200) writes After seven days the Jibo project has over $1.1 million. What is surprising is that Jibo isn't a complex piece of hardware that will do the dishes and pick up clothes. It doesn't move around at all. It just sits and interacts with the family using a camera, microphones and a voice. It is a social robot, the speciality of the founder, MIT's, Cynthia Breazeal. The idea is that this robot will be your friend, take photos, remind you of appointments, order takeaway and tell the kids a story. If you watch the promo video then you can't help but think that this is all too polished and the real thing will fall flat on its face when delivered. If it does work then worry about the hundreds of kids needing psychiatric counselling — shades of Robbie in I, Robot. Even if it is hopelessly hyped — there is a development system and I want one. It is the early days of the home computer all over again.

Metamason: Revolutionizing CPAP Masks With 3D Scanning and 3D Printing

samzenpus posted about a week ago | from the breathing-easy dept.

Medicine 59

First time accepted submitter Leslie Oliver Karpas writes As millions of Americans with Obstructive Sleep Apnea struggle to get a good night's sleep, one company has harnessed 3D technology to revolutionize CPAP therapy. As 3ders.org reported today, "Metamason is working on custom CPAP masks for sleep apnea patients via 3D scanning, smart geometry, and 3D printing." "We're at the crossroads of 3D technology and personalized medicine," says Metamason's founder and CEO. "There are many medical products that would be infinitely more comfortable and effective with a customized fit. CPAP therapy is the perfect example—it's a very effective treatment with a 50% quit rate, because mass-produced masks are uncomfortable and don't fit properly." CPAP is a respiratory device worn during sleep to treat OSA, which affects 1 in 4 men and 1 in 9 women in the US alone. Metamason's "ScanFitPrint" process for creating their custom Respere masks translates a 3D scan of the patient's face into a 3D printed custom mask that is a perfect individual fit. To print the masks in soft, biocompatible silicone, Metamason invented a proprietary 3D printing process called Investment Molding, which creates wholly integrated products that were previously considered "unmoldable."

Raspberry Pi Gameboy

An anonymous reader writes: An enterprising hacker took on a project to rebuild a broken Gameboy using emulation software, a Raspberry Pi, and a few other easily-obtainable parts. The result: success! The hacker has posted a detailed walkthrough explaining all of the challenges and how they were solved. "Using a Dremel, I cut out a most of the battery compartment as well as some posts that on the case for the LCD that would no longer be needed. Doing so, the Pi sits flush with the back of the DMG case. ... The screen was the first challenge. The screen runs off 12V out of the box which wouldn't work with the USB battery pack. The USB battery pack is rated at 5V, 1000mAH so the goal was go modify the screen to allow it to run at 5V. ... I finally got it to work by removing the power converter chip as well as soldering a jumper between the + power in and the resister on the top right."

Robot With Broken Leg Learns To Walk Again In Under 2 Minutes

Unknown Lamer posted about a week ago | from the unstoppable-robot-overlords dept.

Robotics 69

KentuckyFC (1144503) writes When animals lose a limb, they learn to hobble remarkably quickly. And yet when robots damage a leg, they become completely incapacitated. That now looks set to the change thanks to a group of robotics engineers who have worked out how to dramatically accelerate the process of learning to walk again when a limb has become damaged. They've tested it on a hexapod robot which finds an efficient new gait in under two minutes (with video), and often faster, when a leg becomes damaged. The problem for robots is that the parameter space of potential gaits is vast. For a robot with six legs and 18 motors, the task of finding an efficient new gait boils down to a search through 36-dimensional space. That's why it usually takes so long. The new approach gets around this by doing much of this calculation in advance, before the robot gets injured. The solutions are then ordered according to the amount of time each leg remains in contact with the ground. That reduces the dimension of the problem from 36 to 6 and so makes it much easier for the robot to search. When a leg becomes damaged, the robot selects new gaits from those that minimize contact with the ground for the damaged limb. It compares several and then chooses the fastest. Voila! The resulting gaits are often innovative, for example, with the robot moving by springing forward. The new approach even found a solution should all the legs become damaged. In that case, the robot flips onto its back and inches forward on its "shoulders."

SRI/Cambridge Opens CHERI Secure Processor Design

Unknown Lamer posted about two weeks ago | from the dreaming-of-hurd/coyotos dept.

Hardware Hacking 59

An anonymous reader writes with some exciting news from the world of processor design: Robert Watson at Cambridge (author of Capsicum) has written a blog post on SRI/Cambridge's recent open sourcing of the hardware and software for the DARPA-sponsored CHERI processor — including laser cutting directions for an FPGA-based tablet! Described in their paper The CHERI Capability Model: Reducing Risk in an age of RISC, CHERI is a 64-bit RISC processor able to boot and run FreeBSD and open-source applications, but has a Clang/LLVM-managed fine-grained, capability-based memory protection model within each UNIX process. Drawing on ideas from Capsicum, they also support fine-grained in-process sandboxing using capabilities. The conference talk was presented on a CHERI tablet running CheriBSD, with a video of the talk by student Jonathan Woodruff (slides).

Although based on the 64-bit MIPS ISA, the authors suggest that it would also be usable with other RISC ISAs such as RISC-V and ARMv8. The paper compares the approach with several other research approaches and Intel's forthcoming Memory Protection eXtensions (MPX) with favorable performance and stronger protection properties.
The processor "source code" (written in Bluespec Verilog) is available under a variant of the Apache license (modified for application to hardware). Update: 07/16 20:53 GMT by U L : If you have any questions about the project, regular Slashdot contributor TheRaven64 is one of the authors of the paper, and is answering questions.

ClockEndGooner writes Looking for a 3-D printer to help you out with a home project or two? If you're in one of the 12 pilot program areas in the U.S., stop into Home Depot to take a look at and purchase a MakerBot 3-D Replicator printer. "...The pilot program will offer the microwave-sized MakerBot Replicator printers, priced at $2,899, for sale, as well as the smaller Replicator Minis, which list for $1,375. 'This will open up the whole world of 3-D printing to people who wouldn't otherwise know about it—like moms and dads, electricians, contractors and DIY-home-improvement folks,' said MakerBot chief executive Bre Pettis. 'It's a good match.'"

Chinese Company 3D Prints a 2-person Boat

First time accepted submitter Bob768 writes A Chinese company, Sanya Industrial Innovation Design Center, has 3D printed the very first one piece boat. The boat will seat two adults comfortably, and measures 2 meters in length by 0.8 meters wide, and weighs approximately 35 kg. "One interesting fact about the 3D printer used to create this boat, is that it doesn’t require spools of filament, but rather can be fed with raw materials, in the form of pellets or ground up thermoplastics."

New Raspberry Pi Model B+

samzenpus posted about two weeks ago | from the latest-and-greatest dept.

Upgrades 202

mikejuk writes The Raspberry Pi foundation has just announced the Raspberry Pi B+. The basic specs haven't changed much — same BC2835 and 512MB of RAM and the $35 price tag. There are now four USB ports, which means you don't need a hub to work with a mouse, keyboard and WiFi dongle. The GPIO has been expanded to 40 pins, but don't worry: you can plug your old boards and cables into the lefthand part of the connector, and it's backward compatible. As well as some additional general purpose lines, there are two designated for use with I2C EEPROM. When the Pi boots it will look for custom EEPROMs on these lines and optionally use them to load Linux drivers or setup expansion boards. Expansion boards can now include identity chips that when the board is connected configures the Pi to make use of them — no more manual customization. The change to a micro SD socket is nice, unless you happen to have lots of spare full size SD cards around. It is also claimed that the power requirements have dropped by half, to one watt, which brings the model B into the same power consumption area as the model A. Comp video is now available on the audio jack, and the audio quality has been improved. One big step for Raspberry Pi is that it now has four holes for mounting in standard enclosures.

coondoggie writes Taking a page from NASA's rocket powered landing craft from its most recent Mars landing mission, the European Space Agency is showing off a quadcopter that the organization says can steer itself to smoothly lower a rover onto a safe patch of the rocky Martian surface. The ESA said its dropship, known as the StarTiger's Dropter is indeed a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position, where it then switches to vision-based navigation supplemented by a laser range-finder and barometer to lower and land a rover autonomously.
