3D Printed Tank Track Pops Together With Plastic BB For Hinge

3D printing is well-suited to cranking out tank tread designs, because the numerous and identical segments required are a great fit for 3D printing’s strengths. The only hitch is the need for fasteners between each of those segments, but [AlwynxJones] has a clever solution that uses plentiful hard plastic spheres (in the form of 6 mm airsoft BBs) as both a fastener and a hinge between each of the 3D printed track segments. Each segment has hollows made to snugly fit 6 mm BBs (shown as green in the image here) which serve both as fasteners and bearing surfaces. Assembly requires a bit of force to snap everything together, but [AlwynxJones] judges the result worth not having to bother with bolts, wires, or other makeshift fasteners. Bolts or screws are one option for connecting segments, but those are heavy and can get expensive. Segments of printer filament have been successfully used in other tread designs, though that method requires added work in the form of either pins, or heat deforming the filament ends to form a kind of rivet. This design may be a work in progress, but it seems like a promising and clever approach. Probably personal preference, weight and differing size t...

Power of simple physical models for complex protein machines — ScienceDaily

The living cell can be viewed as a factory where protein machines are in charge of various processes, such as transport of material inside the cell or operations with other macromolecules like DNA. Their operation is typically fueled by ATP molecules, the major energy carrier in biological cells. The chemical energy gained through ATP hydrolysis is used by a protein machine to cyclically change its shape and thus to perform a particular function. Hence, resolving functional conformational changes in proteins is a major challenge, with fundamental importance for understanding and control of biological single-molecule motors and machines. The complexity of interactions between atoms in a protein machine is so high that even world’s best supercomputers cannot reproduce just one of their operation cycles. In this review article, it is however demonstrated that essential aspects of the operation of such natural nano-devices can be already revealed by exploring very simple mechanical models of proteins, i.e. by treating such macromolecules as elastic networks obtained by connecting particles by a set of elastic springs. The authors, professor Alexander Mikhailov and assistant pr...

Pilot killed in NYC helicopter crash wasn’t certified to fly in bad weather

NEW YORK — The pilot killed Monday when his helicopter slammed into the roof of a New York City skyscraper was not authorized to fly in limited visibility, according to his pilot certification, raising questions about why he took off in fog and steady rain. Tim McCormack, 58, was only certified to fly under regulations known as visual flight rules, which require generally good weather and clear conditions, according to the Federal Aviation Administration. The rules require at least 3 miles of visibility and that the sky is clear of clouds for daytime flights. The visibility at the time of Monday’s crash was about 1¼ miles at nearby Central Park, with low clouds blanketing the skyline. McCormack was not certified to use instruments to help fly through cloudy or bad weather, said the FAA. The crash in the tightly controlled airspace of midtown Manhattan shook the 750-foot AXA Equitable building, obliterated the Agusta A109E helicopter, sparked a fire, and forced office workers to flee. It briefly triggered memories of 9/11 and fears of a terrorist attack, but authorities said there is no indication the crash was deliberate. Rep. Carolyn Maloney, who represents the area where McCo...

IFA Shift AUTOMOTIVE Conference Gets First Key Partners

During the IFA Global Press Conference last week in Spain, the organizers of IFA 2019 announced the first two key partners for the Shift AUTOMOTIVE conference and exhibition, which runs concurrent to the IFA 2019 show. Car manufacturer smart and IT equipment and services brand Fujitsu will each have a major presence at this year’s show. Shift will take place on September 10 and 11 at IFA in Berlin, and the program will include various educational sessions, panel presentations, and a first-time Shift exhibition on the Messe Berlin fairgrounds. Shift AUTOMOTIVE was debuted at IFA 2018 and is the result of a partnership between IFA, Messe Berlin, the Geneva International Motor Show, and Palexpo. The conference is intended to look beyond the technological breakthroughs and investigate what changes and impacts those technologies will have on transportation and society—and if consumers, businesses, and cities are ready for those changes. “Fujitsu will attend this very special event as one of the key exhibitors and will provide an experience that could propel the visitor’s right into the future of connected mobility through a quantum leap”, Dr. Joseph Reger, CTO CE and EMEIA at Fujits...

When you’ve worked hard to shed any bad ideas about “acceptable” summer bodies and being “swimsuit

When you’ve worked hard to shed any bad ideas about “acceptable” summer bodies and being “swimsuit ready,” there’s no better reward than a summer day you can actually enjoy without the bullshit. And nothing puts the cherry on top quite like an absolutely fire swimsuit that helps you feel hot enough to command control of the pool, the beach, the ocean, and even all the fish who dwell within. But when you’re shopping for swimwear for a large bust, finding that swimsuit can be a challenge, no matter if you’re straight-size or plus-size. The four women photographed for this story had pretty different expectations about what would work for their boobs (and some ended up in suits that surprised them), but all agreed that shopping for swimwear has always been tough. Part of it is the preconceived notions we have about what will work. A quick Google search for swimwear for large busts will bring up a lot of heavily structured and padded options, but there’s more to it than that. Not everyone over a size DD cup  likes the feeling and fit of a swimsuit that’s built like construction scaffolding. On the other hand, if you do want extra support, it can be tough to figure out how, exactly, y...

Walmart Sued By JetBlue For Jetblack Name | PYMNTS.com Walmart Sued By JetBlue For Jetblack Name

The airline said the name is a “transparent attempt” by the retailer to take advantage of the goodwill of the firm, and would probably cause “significant consumer confusion” with the service’s United States expansion, Reuters reported. Randy Hargrove, a spokesperson for Walmart, said per the report, “We respect the intellectual property rights of others. We take this issue seriously, and once we are served with the complaint will respond appropriately with the court.” The airline also noted that the retailer intended more infringements through the use of other names that include “jet,” including colors like Jetsilver and Jetgold, while getting closer to its core business through travel services. At the same time, the complaint noted that JetBlue has 43 federal trademark registrations dating back to before the company started offering transportation services. The company is now one of the biggest airlines in the United States. According to Reuters, “JetBlue and its lawyers did not immediately respond on Monday to requests for comment.” Last May, Walmart announced it was rolling out a same-day delivery service with a twist: Shoppers would be able to text their orders to the retail...

A Routing Scheme to Make Underwater Networks More Reliable

The ocean’s depths have long remained mysterious—a dark abyss where few humans go. But we still have a stake in this alien environment; scientists want to know where pockets of pollution are worst, and where earthquakes occur along the sea floor. Passive sensors can collect such data, but transmitting it in this murky environment is a challenge. Guangjie Han at Hohai University and his colleagues have proposed a new approach for how autonomous underwater vehicles (AUVs) patrolling those depths can better collect data from these sensors. Their design was published 27 March in IEEE Transactions on Mobile Computing. Each sensor, referred to as a node, sits stationary while it collects data. Meanwhile, a fleet of AUVs is dispatched across the network on a predetermined trajectory to collect data from each node. Radio waves are absorbed by water, so underwater sensors and vehicles typically transmit and receive information by using acoustic signals. But sound waves cannot travel as fast or as far in water as radio waves can in the air. And with more AUVs comes more challenges. “Particularly, it is difficult to communicate directly and synchronize the information among AUVs, due to th...

Any limitation this nailer has seems to stem more from Everwin’s claim that it can handle

Any limitation this nailer has seems to stem more from Everwin’s claim that it can handle more than a siding nailer is designed to handle. If you keep in mind that Pros won’t like it for framing or decking, you’ll have a fine siding nailer in your hands! Don’t you love the smell of new tool features in the morning? We’ve come to expect coil nailers to remain generally the same with only marginal tinkering, but Everwin set out to prove us wrong. Since we like better tools, hopefully, Everwin hit the nail on the head with the Everwin Coil Siding Nailer. Although the Taiwanese company has a long pedigree of tool development, it was only founded in 2012, so many Pros might be unfamiliar with it. Everwin is trying to make a splash with some helpful innovation, and we’re here to see if it’s beneficial. The nailer stands out right away because it doesn’t have the familiar color scheme of any of the common manufacturers. There’s no yellow, orange, or all silver that you’d expect to be doing the job.  The Everwin Coil Siding Nailer has a matte gray body and dark red cylinder cap protected by rubberized bumpers on both sides. All of the parts you’d be familiar with – th...
