ErnieKey writes: University of Illinois researchers have created a device, called a Molecular-Machine, which essentially manufactures on the molecular compound level. Martin Burke, the lead researcher on this project says that they are already able to synthesize over a billion different compounds with the machine, compounds which up until now have been very difficult to synthesize. The impact on the pharmaceutical industry could be staggering.

MojoKid writes "Here's your feel-good story for Thursday afternoon. Albert Manero, who has a degree in Aerospace engineering from the University of Central Florida and is currently pursuing a doctorate in Mechanical Engineering, has made it a point to serve others. He helped found Limbitless Solutions, a volunteer foundation that uses 3D printer technology to build bionic arms for children that have either lost a limb, or were born with partially developed limbs. Seven-year-old Alex fits into the latter category and Manero, with the help of the Microsoft OneNote Collective Project, has been hard at work to develop a new 3D-printed bionic arm for him. And once the project was finished, Microsoft and Manero were able to find the most "qualified" person on the planet to deliver the arm to Alex: Tony Stark AKA Iron Man Robert Downey Jr. Awesomeness ensues, of course.

szczys writes "Arduino is a household name in hobby electronics. But now there are two companies calling themselves Arduino and as you've probably guessed this is going to play out in the courts. How can this be? One company started the Arduino movement and used the other company, a contract manufacturer, to actually make the hardware. This went on for a few years before the trademark was actually granted. Elliot Williams did some digging to help figure out how this all might shake out."

ErnieKey writes A man named Eric Harrell has reverse engineered a 5-speed transmission for a Toyota 22RE Engine, and 3D printed an entire working replica on his desktop 3D printer. Even though it is made up almost entirely of plastic, he says that it could function as a replacement for the real thing. In all it took about 48 hours of print time, plus many more in order to assemble the device. He has made the files available for anyone to download and print themselves for free.

An anonymous reader writes In 2013 Cody Wilson posted online the design files needed to 3D print weapons. The files were downloaded at least 100,000 times before the U.S. State Department ordered him to take them down. Last fall he reemerged with a new project, the Ghost Gunner--a relatively small and affordable CNC milling machine that could easily manufacture the lower receiver of an AR-15. It was a different approach toward the same goal of multiplying the number of firearms in the world. But are we really facing a world where backyard bunker-builders are manufacturing their own gun components? Reporter Andrew Zaleski visited Wilson to check on the status of his project. What he found was a man in the throes of small-business hell. As Wilson puts it, "It's like the nightmare of a startup with the added complication that no one will allow you to do it anyway."

Zothecula writes For years now, we've been promised miraculous new flexible touchscreen displays, but the deployment of such technology in big consumer products, like say the LG G Flex, hasn't started any revolutions just yet. That could soon change thanks to a team of computer scientists from Germany's Saarland University who have developed a technique that could allow anyone to literally print their own custom displays, including touchscreens."

In Texas, guns are a common sight:gun-racks are visible in the back of many pick-ups, and pistols, cannons, and rifles are part of the state's iconography. Out-of-sight guns are common, too: The state has had legal (though highly regulated) concealed carry for handguns since 1995, though -- contrary to some people's guess, and with some exceptions -- open carry of handguns is not generally legal. One thing that's definitely not a common sight, though, is a group of people manufacturing guns just outside the south gates of the Texas capitol building. But that's just what you would have encountered a few weeks ago, when an organization called CATI (Come and Take It) Texas set up a tent that served as a tech demo as much as an act of social provocation. CATI had on hand one of the same Ghost Gunner CNC mills that FedEx now balks at shipping, and spent hours showing all comers how a "gun" (in the eyes of regulators, at least) can be quickly shaped from a piece of aluminum the ATF classifies as just a piece of aluminum. They came prepared to operate off-grid, and CATI Texas president Murdoch Pizgatti showed for my camera that the Ghost Gunner works just fine operating from a few big batteries -- no mains power required. (They ran the mill at a slower speed, though, to conserve juice.)

Zothecula writes: Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organization), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world's second one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse.

mpicpp sends an article from Fortune about the tiny industry springing up around food-related 3D printing. While such devices are still too expensive and too special-purpose for home kitchens, professionals in restaurants and large cafeterias are figuring out ways they can automate certain time-intensive tasks. For example, pasta: "If the user is making a recipe for ravioli, for instance, the [device] prints the bottom layer of dough, the filling and the top dough layer in subsequent steps. It reduces a lengthy recipe to two minutes construction time and ensures that no one has to clean a countertop caked with leftover dough and flour." The companies developing these 3D printers hope they'll be this generation's version of the microwave, gradually finding a use in almost every kitchen.

Bruce Perens writes Chris Testa KD2BMH and I have been working for years on a software-defined transceiver that would be FCC-legal and could communicate using essentially any mode and protocol up to 1 MHz wide on frequencies between 50 and 1000 MHz. It's been discussed here before, most recently when Chris taught gate-array programming in Python. We are about to submit the third generation of the design for PCB fabrication, and hope that this version will be salable as a "developer board" and later as a packaged walkie-talkie, mobile, and base station. This radio is unique in that it uses your smartphone for the GUI, uses apps to provide communication modes, contains an on-board FLASH-based gate-array and a ucLinux system. We intend to go for FSF "Respects Your Freedom" certification for the device. My slide show contains 20 pages of schematics and is full of ham jargon ("HT" means "handi-talkie", an old Motorola product name and the hams word for "walkie talkie") but many non-hams should be able to parse it with some help from search engines.

ErnieKey writes: Amazon has been inching its way into the 3D printing space over the past 10 months or so. This week, however, the U.S. Patent office published a filing by Amazon for mobile 3D printing delivery trucks. The trucks would have 3D printers and CNC machines on board and be able to communicate with a central hub. When a product is ordered, the mobile 3D printing truck that's closest to the consumer's home or office would then get the order, print it, and deliver it as soon as possible.

An anonymous reader writes Last fall, Defense Distributed — the company created by Cody Wilson of 3D-printed gun fame — announced a DIY gunsmithing machine called the Ghost Gunner. Now, FedEx is refusing to ship the device, saying there are laws or regulations that would prohibit them from shipment. A FedEx spokesperson said, "This device is capable of manufacturing firearms, and potentially by private individuals. We are uncertain at this time whether this device is a regulated commodity by local, state or federal governments. As such, to ensure we comply with the applicable law and regulations, FedEx declined to ship this device until we know more about how it will be regulated." Wilson argues, "They’re acting like this is legal when in fact it’s the expression of a political preference. The artifact that they’re shipping is a CNC mill. There’s nothing about it that is specifically related to firearms except the hocus pocus of the marketing."

ErnieKey writes The U.S. military is working with technology that will allow them to create exact virtual replicas of their soldiers. In case of an injury, these replicas could be used to 3D print exact medical models for rebuilding the injured patient's body and even exact replica implants. Could we all one day soon have virtual backups of ourselves that we can access and have new body parts 3D printed on demand?

An anonymous reader writes: Writer Adam Estes has tested over a thousand dollars worth of smart home gear from companies like Wink, GE, Lutron, Cree, and Leviton. Most of it worked correctly out of the box — which he said was great. But almost immediately, devices stopped responding and defects manifested themselves. Even after getting replacements and reconfiguring the devices, he found himself wondering if it was worth the effort to wrestle with all these devices, and ended up appreciating the simplicity of a plain old light switch.

Estes says, "Installation woes and bugs aside, my smart home never seemed handy. I had to tape off the regular switches so that the power would stay on and the bulbs' smart features would work. Even then, I had to pull out a smartphone or a tablet any time I wanted to dim the lights. That was never convenient. I could turn the lights on from my office, but that didn't really make my life better. I could impress my friends with a stray smart home feature here and there, but more often than not, I found myself embarrassed by the glitches of my smart home gone dumb." He concludes that while many smart home products can and do work, the biggest lie their marketers tell us is that it'll be simple and easy to set up and operate all these gadgets. Those of you who have wired up parts of your home, how has it worked out so far?

What kind of person builds a cloud chamber at home in his spare time -- and wants to make it easy for other people to make them, too? How about someone who uses a 3-D printer to make shifters for his bicycle? And then there's the spherical speaker enclosures and the alarm clock that shreds money if you don't wake up. The clock isn't original. Seattle resident Rich Olson (whose URL is nothinglabs.com) says someone else originally made it and he liked the idea. No 3-D printing or laser cutting required; just buy and hook up some inexpensive, easy-to-find components and off you go. Despite its lack of originality (which Rich freely admits), this little project got Rich mentioned everywhere from financial publications to the New York Daily News to Huffington Post's UK edition, which is somewhat amusing when you realize that Rich is not famous (outside of a small circle of maker-type people) and doesn't have anyone doing PR for him.

By day, Rich is a humble mobile app developer. But when he's done working he becomes Mr. 3-D and laser cut cool designer guy who does fun things in his workshop with CAD software, a 3-D printer, a laser cutter, and (of course) traditional cutting, drilling, and shaping tools. Since he's an open source devotee, Rich posts almost all of his designs online so you can make them yourself. Or modify them. Or use them to spur an entirely new idea that you can then make, and hopefully pass on to others. While it's interesting to see that Martha Stewart is now selling 3-D printer designs, Rich and his hobby are what the maker movement is really about. If you're so inclined, you can follow Rich on YouTube, where he posts a video now and then that shows what he's made recently or follow his low-volume blog to see what he's up to.

szczys writes Would you do a better job designing hardware if your life depended on it? Chris Nefcy is in that exact position. Years ago he developed an Automatic External Defibrilator for First Medic. The device allows non-doctors to restart a human heart in the field. When Chris had a heart attack his ticker was restarted with shocks from his own hardware. His story isn't just heartwarming, he also covers the path that led him into developing the AED and the bumpy road encountered getting the hardware to market.

An anonymous reader writes: You may recall last September when Mozilla and a new company named Matchstick announced a Kickstarter project for a new device that would compete with Google's Chromecast. It was an HDMI dongle for streaming media that runs on Firefox OS. They easily quadrupled their $100,000 funding goal, and estimated a ship date of February, 2015. Well, they emailed backers today to say that the Matchstick's release is being pushed back to August. They list a few reasons for the delay. For one, they want to upgrade some of the hardware: they're swapping the dual-core CPU for a quad-core model, and they're working on the Wi-Fi antenna to boost reception. But on the software side, the biggest change they mention is that they're adding support for DRM. This is a bit of a surprise, since all they said on the Kickstarter about DRM was that they hoped it would be handled "either via the playback app itself or the OS." Apparently this wasn't possible, so they're implementing Microsoft PlayReady tech on the Matchstick.

sciencehabit writes Researchers have built contraption from LEGOs that can move and rotate insects every which way while keeping them stable and positioned under a microscope. The design improves on previous insect manipulators because it's cheap, customizable, and easy to build. As natural history museums work on digitizing their voluminous collections—taking high-resolution photographs of each precious beetle, bee, and dragonfly in their possession—they have to handle insects repeatedly. Now the job will be easier on the entomologists, and more insect specimens will be able to hang on to their wings—all thanks to LEGOs.

MojoKid writes Here's a dose of Rebel goodness to tide you over while you wait for the next Star Wars trailer. A drone enthusiast in France recently graced the web with a few videos of a self-built quadcopter with a shell designed to look like the Millennium Falcon. It's enough to make a Star Wars fan tear up. The drone features a blue thruster light, just like the real Millennium Falcon, and has bright front lights as well. Its creator, who goes by "Oliver C", has some serious modding skills. The shape of the Millennium Falcon presented Oliver with some challenges, but he has the balance more or less handled by the time the spaceship (or quadcopter) takes its first flight outside.
