Rebuilding the PDP-8 With a Raspberry Pi 86

Posted by Soulskill
from the what's-old-is-new dept.
braindrainbahrain writes: Hacker Oscarv wanted a PDP-8 mini computer. But buying a real PDP-8 was horribly expensive and out of the question. So Oscarv did the next best thing: he used a Raspberry Pi as the computing engine and interfaced it to a replica PDP-8 front panel, complete with boatloads of fully functional switches and LEDs.

Australian Company Creates Even Faster 3D Printer 52

Posted by Soulskill
from the for-when-you-need-new-shower-curtain-rings-NOW dept.
ErnieKey writes: One of the major reasons 3D printing hasn't really caught on is because it's an incredibly slow process. Just last week a company called Carbon3D unveiled a super fast new 3D printing process that utilizes oxygen and light. Now, another company — Gizmo 3D — has unveiled an even faster 3D printing process which is claimed to be more reliable than the process presented by Carbon3D. It can print 30mm in height at a 50 micron resolution in just 6 minutes.

New 3D Printing Process Claimed To Be 25X Faster Than Current Technology 95

Posted by Soulskill
from the may-be-t1000-in-disguise dept.
ErnieKey writes: Carbon3D, a startup based in Redwood City, CA. has just announced a new breakthrough 3D printing technology called Continuous Liquid Interface Production technology (CLIP). The process works by using oxygen as an inhibiting agent as a UV light rapidly cures a photosensitive resin (abstract). "Conventional 3D printers usually take several hours to print an object — because with most printing methods, they need to individually treat each new layer of material after it's put down so that the next layer can be put down on top of it. The new method is much faster because it works continually, instead of in layers, eliminating this step. As a result, it works in minutes, rather than hours — 25 to 100 times faster, its creators say, than conventional 3D printing." The company has just emerged from stealth mode and announced that they have raised a staggering $41 million to further develop the process and bring it to market.

Maker Person Rich Olson Returns (Video) 42

Posted by Roblimo
from the not-everything-is-about-money dept.
In February we ran a video titled Rich Olson Embodies the Spirit of the Maker Movement. We aren't saying Rich is a superman, but more like everyman or, in this case, everymaker. He is a hobbyist who, like many others, shares his designs freely in the best spirit of open source. Today we have some more words from Rich that may help you if you are just starting to use a 3-D printer and similar tools either at home or in a makerspace. and a note: If you know someone we should interview, please email robinATroblimoDOTCOM.

from the go-big-or-go-home dept.
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.

Tony Stark Delivers Real 3D-Printed Bionic Arm To 7-Year Old Iron Man Fan 43

Posted by samzenpus
from the but-I-wanted-repulsors dept.
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.

Fight Over Arduino Name Pits Originators Against Contract Manufacturer 33

from the in-a-name-is-money dept.
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."

Man 3D Prints a Working 5-Speed Transmission For Toyota Engines 230

Posted by timothy
from the that's-awesome dept.
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.

Cody Wilson Wants To Help You Make a Gun 449

Posted by samzenpus
from the print-and-shoot dept.
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."

PrintDisplay: DIY Displays and Touchscreens Anyone Can Print 14

Posted by samzenpus
from the print-and-watch dept.
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."

Come and Take It, Texas Gun Enthusiasts (Video) 367

Posted by timothy
from the a-lower-receiver-can-be-an-entire-gun-under-the-law dept.
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.

3D Printers Making Inroads In Kitchens 91

Posted by Soulskill
from the license-to-print-honey dept.
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.

Developers Disclose Schematics For 50-1000 MHz Software-Defined Transceiver 135

Posted by samzenpus
from the fire-up-the-boat-anchor dept.
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.
