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.

New submitter jigmypig writes: One of the main issues with 3D printers today is that they lack in one area; speed. A 15-year-old boy named Thomas Suarez is developing a 3D printer that he says is the most reliable, most advanced, and faster than any 3D printer on the market today. In fact he claims it is 10 times faster than any 3D printer ever created. "There's something that makes me want to keep going and keep innovating," he says, laughing at being asked if he'd be better off outside climbing trees or riding a bike. "I feel that my interests will always lie in technology. Maybe I should go outside more but I just really like this stuff."

The new kid on the block, known as the HummingBoard can handle faster processors, more RAM and will fit the same cases for the Pi. Also, you can expand the memory and the CPU is replaceable! The low end model starts at $45 and the high end costs $100. So tell me guys, what are you going to do with yours?" $45 model is a single core iMX6 (an ARMv7) with 512M of RAM, the $100 model has a dual core i.MX6 with 1G of RAM. Full specs.

The 3D files can be found on Thingiverse, and a video of the finished product is provided as well."

First time accepted submitter Franz Struwig writes "MAKE Magazine has a great review of a bicycle radar product — showing off some of the early prototype innards: "The latest version features a 24 GHz radar antenna — high enough to resolve more targets and small enough to fit on a bike — an ARM processor, and Bluetooth LE to communicate with the front unit. The radar creates a doppler map, and recognizes not only the vehicle, but how far away it is and how quickly it’s approaching. It communicates this to the cyclist by a system of LEDs, and to the car by increasing the rate at which the tail light blinks as the car gets closer."

Lucas123 writes: A company in China has used additive manufacturing to print 10 single-room buildings out of recycled construction materials in under a day as offices for a Shanghai industrial park. The cost: about $5,000 each. The company, Suzhou-based Yingchuang New Materials, used four massive 3D printers supplied by the WinSun Decoration Design Engineering Co. Each printer is 20 feet tall, 33 feet wide and 132 feet long. Like their desktop counterparts, the construction-grade 3D printers use fused deposition modeling (FDM), where instead of thermoplastics layer after layer of cement is deposited atop one another. The cement contains hardeners that make each layer firm enough for the next. Yingchuang's technique builds structures off site in a factory one wall at a time. The structures are then assembled onsite. The technique is unlike U.S.-based Contour Crafting, a company whose 3D printing technology to form the entire outer structure of buildings at once, The Yingchuang factory and research center, a 33,000 square foot building, was also constructed using the 3D printing manufacturing technique. It only took one month to construct.

Project Tango is part of Google's Advanced Technology and Projects group (ATAP), which Wikipedia says was "...formerly a division of Motorola." Tango's goal is "to give mobile devices a human-scale understanding of space and motion." We humans and our forebears have spent millions of years learning to sense our surroundings, not as a set of static 2D images, but in 3D with motion. This YouTube video starring Johnny Lee, the Tango project lead Tim interviewed at Google I/O 2014, gives you some decent insight into Project Tango's goals -- in addition to our video, that is.

Tekla Perry writes: We cook our food today using technology invented to bake bricks. We can do a lot better. Nathan Myhrvold explains what's wrong with today's ovens and challenges oven designers make them better. He says, "Oven designers could do a lot to make ovens heat more evenly by taking advantage of the different ways ovens transfer heat at different cooking temperatures. At 200 C or below, convection moves most of the heat. But at 400 C, radiant energy starts doing a fair amount of the heat transfer. At 800 C, radiation overwhelms convection. Why couldn't we have an oven designed to cook primarily by convection at low temperatures that switches to radiant heating for high-temperature baking? ... The shiny skin of raw fish reflects heat, but as the skin browns, it reflects less and less energy. That’s why food under a broiler can seem to cook slowly at first and then burn in the blink of an eye. But technology offers a fix here, too. Oven designers could put optical sensors in the oven chamber to sense the reflectivity of the food, and then the oven controller could adjust the heat automatically or at least alert the cook as the surface browns. And a camera in the oven could feed to a color display on the front panel, giving the chef a clearer view of the food than a small window in the door can. Indeed, a decent optics system could allow designers to dispense with the glass in the door altogether, reducing the gap between the hottest and coolest corners of the oven and obviating the need to open the door and rotate the food midway through cooking.

mikejuk (1801200) writes Due to its importance in the history of computing, the UK's Computer Conservation Society embarked on a 4-year project to build a replica of EDSAC. The main challenge facing the team of volunteers who are working on the rebuild is the lack of documentation. There are almost no original design documents remaining so the rebuild volunteers have to scrutinize photographs to puzzle out which bits go where. However, three years into the project, a set of 19 detailed circuit diagrams have come to light and been handed to the EDSAC team by John Loker, a former engineer in the University of Cambridge Mathematical Laboratory. "I started work as an engineer in the Maths Lab in 1959 just after EDSAC had been decommissioned. In a corridor there was a lot of stuff piled up ready to be thrown away, but amongst it I spotted a roll of circuit diagrams for EDSAC. I'm a collector, so I couldn't resist the urge to rescue them. " In the main, the documents confirm that the team has been correct in most of its re-engineering assumptions, but the drawings have thrown up a few surprises. The most significant discrepancy between the original and the reconstruction that the papers reveal is in the "initial orders" (boot ROM in modern terminology). In the absence of fuller information, the reconstruction team had considered and rejected one possibility which was in fact the one that was used by the original engineers. That will now be rectified in the reconstruction, which is due for completion in late 2015.

Last week at Google I/O, the company introduced Cardboard, its cheap-and-cheerful (it's made of cardboard, after all) approach to nearly instant VR viewing. It's no Oculus Rift — lacking the Rift's connection to a powerful backend PC, it can't do the same heavy lifting. In fact, it looks sort of like a prank, and the announcement at I/O that everyone at the conference would be getting "a piece of cardboard" drew a lot of chuckles. Gigaom argues that it's nonetheless extremely valuable, because it makes immersive viewing easy and cheap for anyone with a fairly capable smartphone — a pretty satisfying experience in itself, and a good taste of what even higher-end viewers can bring. "In addition to the Cardboard app," writes an anonymous reader, "Google has pushed out an updated version of Google Maps which includes a VR mode for Street View." And if you weren't blessed with an I/O pass, and aren't sure about your skills cutting one out of a pizza box, note that you can buy a kit for about $25, including the RF tag that will tell a phone to fire up the Cardboard app. (The linked article says an aluminum version is in the works from at least one company; I'd like to see one in corrugated plastic — strong but light — and with connection points for a headstrap.) If you've made something similar (or would like to), what would you improve in the design or feature set? (Look soon for a video introduction to Cardboard with Google VP Clay Bavor, too.)

An anonymous reader writes with this story about a machine-learning project out of the UK's University of Sheffield: Using simple drones the researchers have created automatic-control software that enables the "flying robot" to learn about its surroundings using a camera and an array of sensors. The robot starts with no information about its environment and the objects within it. But by overlaying different frames from the camera and selecting key reference points within the scene, it builds up a 3D map of the world around it. Other sensors pick up barometric and ultrasonic data, which give the robot additional clues about its environment. All this information is fed into autopilot software to allow the robot to navigate safely, but also to learn about the objects nearby and navigate to specific items.

fluxgate (2851685) writes "A notice from the FAA announced earlier this week just turned a bunch of kids' toys into drones. In the past, the FAA had made the distinction between model aircraft (allowed) and drones (prohibited without special permission) according to whether they were used for recreation (okay) or commercial purposes (verboten). Now they have further narrowed the definition of model aircraft: If you fly it through video goggles, it no longer qualifies. This move eliminates First Person View (FPV) radio control flying. I'm an editor at IEEE Spectrum with a special interest and blogged about this disturbing development as soon as I heard the news."

First time accepted submitter themusicgod1 (241799) writes According to 2600, their distributor (Previously known as "Source Interlink", now recently renamed to "TEN: The Enthusiast Network") has decided to consolidate its resources and is keeping the money retailers paid for the last two issues of the quarterly magazine. 2600, in the meanwhile, is still busy trying to organize the upcoming HOPE X conference. However, according to the link: "In the worst case scenario, being ripped off at this level would make it almost impossible for us to continue publishing. We would have to make a lot of painful choices and cut back on things for no reason other than some outside company's mismanagement. Our readers have supported both our print and digital publications and we've been doing quite well overall." Note: As it says at the linked explanation, 2600 is not a charity, and they're not seeking donations -- but they would like you to buy the magazine (in print or Kindle form), and to attend the upcoming HOPE X conference. (I wish I could make this year's HOPE but can't; as conferences go, HOPE is a wildly good bargain.)

An anonymous reader writes UNYQ (pronounced: unique), a start-up based in San Francisco and Seville, has set out to change the way we look at prosthetics by selling affordable 3D printed prosthetic leg covers, known as "fairings," directly to consumers. The company was co-founded by Eythor Bender, who is best known for developing a prototype bionic exoskeleton that allows paraplegics to walk again. Bender, who has worked with the disabled for over 20 years, was frustrated by the lack of consideration of style in the medical device development process. Despite all the progress made in other areas, the devices still look more or less like a "wooden stick." Bender wants to challenge what we think is possible with prosthetics.

cartechboy writes Tired of waiting for self-driving cars from the automakers? If 2017 and 2020 just feel too far away there's now a solution. It's called Cruise, and for $10,000 it'll turn your current ride into a self-driving car. Kyle Vogt started the company and recruited a team of engineers and roboticists from MIT to work on autonomous vehicles. Cruise plans to market the hardware as something that can be retrofitted to existing cars using roof-mounted sensors near the windshield, actuators to operate the controls, and a trunk-mounted computer that manages everything. The idea is that drivers can merge onto the highway and simply hit the "Cruise" button on the dashboard. This will engage the system and basically turns the car on autopilot. The system can use the steering, brakes, and throttle to keep the car in its lane. Currently the first system, called RP-1, only works on current-generation Audi A4 and S4 models. RP-1 is currently available for pre-order with the launch set for near year.

jfruh writes Intel is developing a series of robot kits for hobbyists, ranging from "Jimmy", a $1,500 "social robot," to a more robust $16,000 model. The robots are powered by Intel x86 chips, are programmable, and can have exoskeletons parts produced at home by 3-D printers. From the article: "The two-legged Jimmy will be one in a line of robots that Intel hopes do-it-yourself enthusiasts will embrace, developing more functionality for the robots, which will be able to handle tasks such as turning on lights, picking up newspapers and even having conversations, researchers said at the Intel Future Showcase 2014 in New York City Tuesday. Intel and its robotics partners will sell kits with servo motors, batteries, boards, a frame and other internal parts. Using 3D printers, users can create robot designs and place them on the exoskeleton."

curtwoodward writes: Google bought Nest. Then Nest bought Dropcam. Then Nest opened up its platform to tech partners, including... Google. This may not creep everyone out, but for those who don't like the idea of Google's all-seeing eye owning their smart-home devices, there are some small, independent companies developing alternatives. Maybe they'll survive long enough to get acquired by a company that doesn't make 90 percent of its money from advertising — right?

An anonymous reader writes: Here's a fun project: engineer Yuriy Guts built a Visual Studio extension that lets people program using MIDI instruments. You can write code letter by letter on a piano keyboard. Granted, it's not terribly efficient, but it's at least artistic — you can compose music that is also a valid computer program. Somewhat more usefully, it also allows you to turn a simple MIDI input device, like a trigger pad into a set of buttons that will run tests, push/pull code, or other tasks suitable for automation. The extension is open source and open to contributions.

Their main claim: "Sigsense Sensors are field-switchable sensing modules which replace the current generation of single purpose instruments. All Sigsense Sensors connect to the Sigsense Wireless Dock through a common interface. This portability and convenience allows workers to always carry the right instrument for the job." In other words, a technician in a food manufacturing plant doesn't need to carry a humidity-measuring tool, a multimeter, a signal strength meter, and four or five other measuring tools, to the point where he's got a backpack full of instrumentation or a rolling a cart full of measuring devices. That technician can now (in theory) carry a single, wireless sensor body, and put the sensors he needs on it as easily as you change heads on an electric hair trimmer. Check their blurb on AngelList for more about what this company is up to, and note that they are going way beyond making one measurement at a time. They're talking about collecting instrument data, along with tracking technicians, and sending all this data to the cloud, where you can do with it as you wish. But not today. The website says they will have products available "soon." (Alternate Video Link)

rtoz writes: Researchers have found a new material design based on the use of microlattices with nanoscale features, combining great stiffness and strength with ultralow density. The actual production of such materials is made possible by a high-precision 3-D printing process called projection microstereolithography. Normally, stiffness and strength declines with the density of any material; that's why when bone density decreases, fractures become more likely. But using the right mathematically determined structures to distribute and direct the loads, the lighter structure can maintain its strength. This newly invented material is among the lightest in the world. It can easily withstand a load of more than 160,000 times its own weight.
