Haydon's newest product line of leadscrew assemblies offers a wide selection of leadscrews made from 303 stainless steel, with Haydon's very own precision rolling process and a tight lead accuracy. They range in diameter from .1875 to .375 inches, and are available with Haydon's Black Ice™ coating, that prevents common flaking problems with other PTFE coatings. The new nuts eliminate typical backlash between the leadscrew and nut interface, making them ideal for precise positioning applications. The nuts are made from Haydon's own self-lubricating polyacetal. Coupled with the screws, there is low drag torque and smooth operation. All the nuts need is Haydon's standard lubricant to work for the life of the application without relubrication, and with Haydon's Black Ice™-coated screws, no lubrication is needed. There are three anti-backlash styles and a new, low-profile freewheeling design. The new nuts are available in a number of diameters and leads, come with a thread mount and can be customized with a variety of standard or special flange configurations.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
