Startup Helps You Build Your Very Own Picosatellite On a Budget 21

Posted by samzenpus
from the to-infinty-and-beyond dept.
Zothecula writes A Glasgow-based startup is reducing the cost of access to space by offering "satellite kits" that make it easier for space enthusiasts, high schools and universities alike to build a small but functional satellite for as little as US$6,000 and then, thanks to its very small size, to launch for significantly less than the popular CubeSats.

NASA Tests Feasibility of 3D Printing on the Moon and Other Planets 58

Posted by samzenpus
from the in-space-nobody-can-hear-you-print dept.
ErnieKey writes A major application of 3d printing that could revolutionize space travel would be using 3d printers to create structures on non-terrestrial bodies like the moon, other planets, and even asteroids. Researchers from NASA's Kennedy Space Center have been working to develop solutions to materials issues, and recently presented initial findings on the potential for using in-situ materials like basalt for 3D printing. Their innovative method is based on only using in-situ supplies, and not materials that need to be brought into space.

The Personal Computer Revolution Behind the Iron Curtain 114

Posted by samzenpus
from the do-what-you-can dept.
szczys writes Obviously the personal computer revolution was world-wide, but the Eastern Bloc countries had a story of PC evolution all their own. Martin Malý tells first hand of his experiences seeing black market imports, locally built clones of popular western machines, and all kinds of home-built equipment. From the article: "The biggest problem was a lack of modern technologies. There were a lot of skilled and clever people in eastern countries, but they had a lot of problems with the elementary technical things. Manufacturing of electronics parts was divided into diverse countries of Comecon – The Council for Mutual Economic Assistance. In reality, it led to an absurd situation: You could buy the eastern copy of Z80 (made in Eastern Germany as U880D), but you couldn’t buy 74LS00 at the same time. Yes, a lot of manufacturers made it, but 'it is out of stock now; try to ask next year.' So 'make a computer' meant 50 percent of electronics skills and 50 percent of unofficial social network and knowledge like 'I know a guy who knows a guy and his neighbor works in a factory, where they maybe have a material for PCBs' at those times."

mikejuk (1801200) writes "When British astronaut Tim Peake heads off to the International Space Station in November, 2015, he will be accompanied on his 6-month mission by two augmented Raspberry Pis, aka Astro Pis. The Astro Pi board is a Raspberry Pi HAT (short for Hardware Attached on Top), and provides a gyroscope, accelerometer, and magnetometer, as well as sensors for temperature, barometric pressure, and humidity. It also has a real time clock, LED display, and some push buttons — it sounds like the sort of addon that we could do with down here on earth as well! It will also be equipped with both a camera module and an infra-red camera. UK school pupils are being challenged to write Raspberry Pi apps or experiments to run in space. During his mission, Tim Peake will deploy the Astro Pis, upload the winning code while in orbit, set them running, collect the data generated and then download it to be distributed to the winning teams.

PC Magazine reports (citing a blog post from project manager Andrew Nartker) that Google's Cardboard -- first introduced to some laughter -- is growing up, with a small but growing collection of compatible apps and a recently announced SDK. And while Cardboard itself is pretty low-tech (cardboard, rubber band, a magnet) and consequently cheap, the resulting VR experience is pretty good, which explains why more than 500,000 of them have now shipped.

Doctors Replace Patient's Thoracic Vertebrae With 3D-Printed Replica 55

Posted by timothy
from the unbeatable-bragging-rights dept.
ErnieKey (3766427) writes Earlier this month, surgeons at Zhejiang University in China performed a surgery to remove two damaged vertebrae from a 21-year-old patient. In their place they inserted a 3D printed titanium implant which was shaped to the exact size needed for the patient's body. The surgery, which took doctors much less time and provided significantly less risk [than conventional surgery] was completely successful and the patient is expected to make a full recovery. This is said to be the first ever surgery involving 3D printing vertebrae in order to replace a patient's thoracic vertebrae.

3D Printer Owner's Network Puts Together Buyer's Guide 62

Posted by Soulskill
from the what's-the-best-under-$17 dept.
Lucas123 writes: Thousands of 3D printer owners who are part of a distributed online network were tapped for a buyer's guide, rating dozens of machines from tiny startups to major manufacturers. Surprisingly, the big-name 3D printer makers were nowhere to be found in the top picks. More obscure companies, like Makergear, a 12-person start-up in Ohio, or Zortrax, a Polish company that began as a Kickstarter project, took top spots in the reviews. The buyer's guide, put together by 3D Hubs, contains five different categories: Enthusiast Printers, Plug-n-Play Printers, Kit/DIY Printers, Budget Printers and Resin Printers. In all, 18 models made it to the top of the user communities' list, and only printers with more than 10 reviews were included in the buyer's guide. 3D Hubs also added a secondary "Printer Index" that includes 58 3D Printers that didn't make it to the top of their categories. Printers with more than five reviews are displayed in the index.

$35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O 140

Posted by Soulskill
from the more-competition-more-innovation dept.
DeviceGuru writes: Hardkernel has again set its sights on the Raspberry Pi with a new $35 Odroid-C1 hacker board that matches the RPI's board size and offers a mostly similar 40-pin expansion connector. Unlike the previous $30 Odroid-W that used the same Broadcom BCM2835 SoC as the Pi and was soon cancelled due to lack of BCM2835 SoC availability, the Odroid-C1 is based on a quad-core 1.5GHz Cortex-A5 based Amlogic S805 SoC, which integrates the Mali-400 GPU found on Allwinner's popular SoCs. Touted advantages over the similarly priced Raspberry Pi Model B+ include a substantially more powerful processor, double the RAM, an extra USB2.0 port that adds Device/OTG, and GbE rather than 10/100 Ethernet.

Economist: US Congress Should Hack Digital Millennium Copyright Act 129

retroworks writes This week's print edition of The Economist has an essay on the Right to Tinker with hardware. From the story: "Exactly why copyright law should be involved in something that ought to be a simple matter of consumer rights is hard to fathom. Any rational interpretation would suggest that when people buy or pay off the loan on a piece of equipment—whether a car, a refrigerator or a mobile phone—they own it, and should be free to do what they want with it. Least of all should they have to seek permission from the manufacturer or the government."

Using Discarded Laptop Batteries To Power Lights 143

Posted by Soulskill
from the i-bet-fresh-laptop-batteries-would-work-even-better dept.
mrspoonsi sends news of an IBM study (PDF) which found that discarded laptop batteries could be used to power lights in areas where there's little or no electrical grid. Of the sample IBM tested, 70% of the used batteries were able to power an LED light for more than four hours every day throughout an entire year. The concept was trialed in the Indian city of Bangalore this year. The adapted power packs are expected to prove popular with street vendors, who are not on the electric grid, as well as poor families living in slums. The IBM team created what they called an UrJar — a device that uses lithium-ion cells from the old batteries to power low-energy DC devices, such as a light. The researchers are aiming to help the approximately 400 million people in India who are off grid.

You can spend less than $500 if you like. That's the maximum amount allowed if you're competing in the Power Racing Series. Interviewee Josh Lee is a member of the Southern Polytechnic State University Electric Vehicle Team. The modified electric 'ride on' toy they showed off and raced at Maker Faire Atlanta (where this video was made) is just one of their many projects. And, obviously, they're just one of many 'slightly deranged' teams involved in learning about and building electric vehicles. (Alternate Video Link)

Ben Harris Shows off the Electric Vehicle Challenge Simulator (Video) 37

Posted by Roblimo
from the not-as-fast-as-a-tesla-but-costs-a-lot-less dept.
EVChallenge is a high school student project that converts gas cars to electric. This isn't a "someday" thing. It's already happening, and Ben has worked hard to make it so in N. Carolina. There are other people around the world doing EVChallenge, and Ben does a number of things besides EVChallenge. His Kickstarter project, for instance, was called Help Bring Back Quality Science Kits (STEM Education). It closed on October 17 after 119 backers came through with $6523, which was a lot more than Ben's modest $3500 goal. This takes us to Ben's EVChallenge simulator itself, which is a simple "breadboard" simulation of the circuitry that drives an electric car so students can learn EV (electric vehicle) principles before they work on the real thing.

This is all part of the Harris Educational effort to make science teaching fun and interesting, not just with electric cars and simulations of their circuitry, but with other kits and even training services. As Ben's Training Services page says, "Harris Educational can provide face-to-face or online training for individuals, small groups, or companies. We can also help you design and implement your own training programs." So besides the video interview here, please look at Ben's pages, this article about his work, and check some of the videos on his assorted pages. It's good stuff, especially if you have (or plan to have) kids in high school. (Alternate Video Link)

Who Needs NASA? Exoplanet Detected Using a DSLR 108

Posted by timothy
from the small-cheap-everywhere dept.
Iddo Genuth writes Until 20 years ago even the best telescopes in the world could not detect a planet outside our solar system. Now, with the aid of a basic DSLR, low cost lens and some DIY magic, you just might be able to "see" ET's home planet for yourself. Your DSLR can do much more than just take a few nice portraits or the occasional vacation photos – if you have some DIY experience (O.K. a bit more than just "some"), you might be able to repeat what David Schneider was recently been able to do — that is, building his own planet finder using only inexpensive photo gear, low cost electronics, the right kind of software and a lot of patience. Although Schneider was "only" able to rediscover an already known exsoplanet (some 63 light-years away from us), what he did — and more importantly how he did it — might allow planet hunting to become closer to SETI@home than NASA's 550,000 million dollar Kepler space telescope project.

Fly With the Brooklyn Aerodrome (Video) 22

A bit of housing insulation material, a battery, a motor and propellor, a radio receiver and transmitter, and servos to control the motor and a pair of ailerons, and you're ready to fly the Brooklyn Aerodrome way. This isn't a tiny radio-controlled paper airplane, but a big bruiser with a 1:1 power to weight ratio (which means it can climb like a bat out of hell) and enough guts to fly in reasonably windy conditions while carrying a camera -- except we'd better not mention cameras, since Brooklyn Aerodrome creations, whether kits or plans, are obviously intended tohelp you build model airplanes, not drones. Timothy ran into project proponent Breck Baldwin at a maker faire near Atlanta, surrounded by a squadron of junior pilots who may someday become astronauts on the Moon - Mars run -- or at least delivery drone controllers for Amazon.

ISS's 3-D Printer Creates Its First Object In Space 69

Posted by Soulskill
from the made-in-space dept.
An anonymous reader writes: NASA reports that the 3-D printer now installed on the International Space Station has finally finished its first creation. After it was installed on November 17th and calibrated over the next week, ground control sent it instructions yesterday to build a faceplate for the extruder's own casing. The process was mostly a success. "[Astronaut Butch Wilmore] Wilmore removed the part from the printer and inspected it. Part adhesion on the tray was stronger than anticipated, which could mean layer bonding is different in microgravity, a question the team will investigate as future parts are printed. Wilmore installed a new print tray, and the ground team sent a command to fine-tune the printer alignment and printed a third calibration coupon. When Wilmore removes the calibration coupon, the ground team will be able to command the printer to make a second object. The ground team makes precise adjustments before every print, and the results from this first print are contributing to a better understanding about the parameters to use when 3-D printing on the space station."

This project is based on the same Galileo boards Intel has used to support some high-altitude balloon launches -- except this is an extremely simple, practical application. Open source? You bet!

In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubbornness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the C standard library, it finally works! (video)"

Collin Graver and his Wooden Bicycle (Video) 71

Posted by Roblimo
from the we'll-stick-to-our-metal-bikes-for-the-moment-thank-you dept.
This is not a practical bike. "Even on smooth pavement, your vision goes blurry because you're vibrating so hard," Collin said to an Atlanta Journal-Constitution reporter back in 2012 when he was only 15 -- and already building wooden bicycles. Collin's wooden bikes are far from the first ones. Wikipedia says, "The first bicycles recorded, known variously as velocipedes, dandy horses, or hobby horses, were constructed from wood, starting in 1817." And not all wooden bicycles made today are as crude as Collin's. A Portland (OR) company called Renovo makes competition-quality hardwood bicycle frames -- for as little as $2200, and a bunch more for a complete bike with all its hardware fitted and ready to roll.

Of course, while it might be sensible to buy a Renovo product if you want a wood-framed bike to Race Across America, you won't improve your woodworking skills the way Collin's projects have improved his to the point where he's made a nice-looking pair of wood-framed sunglasses described in his WOOD YOU? SHOULD YOU? blog. (Alternate Video Link)
