The TEN-HIGH 60W Laser Cutter is a powerful laser cutter/engraver that provides hobbyists with professional quality at an affordable price. Review the features and specs to learn more. When harnessing the incredible force of a laser cutter or engraver, one must come to accept that their creative capabilities are only as powerful as the laser itself. Combine a low-powered laser and a tiny engraving area, you can start to see why most desktop-sized machines don’t quite make the cut for hobbyists and prosumers. You might need more industrial strength to actualize you engraving and cutting needs, but that doesn’t necessarily mean you have to pay an industrial price to achieve it. Similar to the desktop 3D printer market, there are a number of low-cost, Chinese-made laser cutting/engraving machines that have made the technology more accessible to all. We recently took a look at the TEN-HIGH 40W, a laser engraver that has become popular on web-based retailers like Amazon and Ali Express. Now, we’ll kick things up a notch with the more powerful and robust member of the laser engraving family: the TEN-HIGH 60W. Priced right around $3,000, the TEN-HIGH 60W is certainly not built for ent...

Machine-learning systems are black boxes even to the researchers that build them. That makes it hard for others to assess the results. A few years ago, Joelle Pineau, a computer science professor at McGill, was helping her students design a new algorithm when they fell into a rut. Her lab studies reinforcement learning, a type of artificial intelligence that’s used, among other things, to help virtual characters (“half cheetah” and “ant” are popular) teach themselves how to move about in virtual worlds. It’s a prerequisite to building autonomous robots and cars. Pineau’s students hoped to improve on another lab’s system. But first they had to rebuild it, and their design, for reasons unknown, was falling short of its promised results. Until, that is, the students tried some “creative manipulations” that didn’t appear in the other lab’s paper. Lo and behold, the system began performing as advertised. The lucky break was a symptom of a troubling trend, according to Pineau. Neural networks, the technique that’s given us Go-mastering bots and text generators that craft classical Chinese poetry, are often called black boxes because of the mysteries of how they work. Getting them to p...

SPRINGDALE — The state is investigating a report that a firm hired to haul an estimated 117,000 gallons of wastewater from Bethel Heights applied it to land east of Springdale without a permit, officials confirmed Monday. Arkansas Department of Environmental Quality officials said the investigation involves White River Environmental Services and land owned by Harold Parsons. The land is in the White River watershed. Jeff LeMaster, a policy adviser for the department’s Office of Water Quality, said the agency has no record of a permit allowing White River to discharge wastewater at that site or elsewhere. The hauler, upon request, provided the state with coordinates for an access gate to the land on Parsons Road, LeMaster said. White River Environmental told the department this was where the Bethel Heights wastewater was applied in late August, LeMaster said. “We’ve requested records from both the city and White River,” LeMaster continued. “But it’s still too early to tell who’s at fault.” Emails sent Monday to Bethel Heights Mayor Cindy Black and Robert Rhoads, an attorney representing the city, were not returned Monday night...

Editors Message:A recent review of Metrology News readership statistics exhibited a 40% increase year to-date demonstrating the magazine profile continues to grow significantly within the manufacturing metrology sector. September was another busy month for Metrology News with the publication of more than 50 articles, many of which were associated with new product introductions at the significant EMO metalworking exhibition in Hanover, Germany and demonstrating the metrology sector continues to innovate and introduce new technologically advanced products.

The kid was born with a Hot Wheels in his hand, or at least that’s what Peter Georgeades told STREET RODDER when asked how long he’s been interested in cars. We’ll skip past how many Hot Wheels cars Pete collected in his pre-driver license days and spin the yarn of Pete’s 1930 Model A coupe and how watching American Graffiti as a kid locked-in the inspiration to spend 10 years of his early adulthood building a hot rod. It wasn’t all Pete; thanks to meeting Ron Cambra, the Model A project had a mentor with a vision and was on the pay-as-you-go plan. Pete met Cambra while he was building cars from his home shop and the “A” project relocated when Cambra opened the doors to Cambra Speed Shop in Orange, California. The starting point was a $400 1930 Model A coupe body Pete found behind a coffee roasting company’s alley in Hayward, California, and hauled south. At Cambra’s home shop he told Pete the coupe body was rusted junk and he needed to find something in better condition. The search led to Craigslist where Pete found a complete running 1930 Model A and swapped bodies. The running Swiss cheese Model A was flipped on Craigslist. Ever since his early childhood, checking out competi...

CEDAR RAPIDS, Iowa (KCRG) – People toured some historic Cedar Rapids school buildings on Friday evening on a school bus. The group Save CR Heritage organized the event. Local historian Mark Stoffer Hunter explained the unique characteristics of the city’s school buildings. Historians are talking about these buildings because there will be changes coming soon. The Cedar Rapids School District’s facilities master plan was approved in January 2018. It called for 21 elementary schools to be closed, rebuilt, or renovated. Greg O’Connell has been the principal at Coolidge for nine years.Five hundred students from preschool to fifth grade fill the classrooms. But the school, which was built in 1967, has its downsides. In the library, the sinking floor causes it to be so uneven, pencils roll right off desks. The building has the same boiler today as when it was opened.Window air conditioning units are used to keep the kids cool. Some students are as young as three. It’s also a challenge to make the building accessible for all. “When you look at older buildings, one of the hardest parts is trying to figure out how to fit in some of the ADA compliance into an exis...

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 – the...

VQ, the latest series of end mills from Mitsubishi Materials has been further expanded to include an innovative new six-flute, conical taper barrel type. This latest addition has been specially designed for high efficiency finish machining of titanium alloy blades and for milling other materials from mild steel through to aluminium alloys. The ability to outperform standard ball nose end mills is provided by the large conical taper barrel form that blends seamlessly with the nose radius. This larger tangential radius permits a much greater overlap and therefore greatly reduces the number of passes required to cover the surface area of the material being machined. The larger overlap also leads to significant improvements in the surface finish. Additionally, the six-flute geometry permits greater feeds and promotes further savings in machining time. When compared to ball nose end mills, the conical taper form with the much larger area of contact with the workpiece during barrel milling could lead to chatter and vibration, but this concern is negated by the irregular pitch geometry of the flutes. The radial accuracy of ±0.01mm for the end (RE1) and barrel radii (RE2) are also key f...
