Groschopp's PS2300 is compatible with all Groschopp ac, PM and dc brushless motors, with high continuous duty torque ratings up to 320 inches-lb. With an efficient design and unique use of synthetic lubricants, it stays cool and works well in industrial conveyors or commercial garage door openers, which need high start and stop torque. It has a powder-coated cast aluminum housing and standard face and foot mounts with optional custom mounts. Internal ball bearings and needle bearings on the output shaft provide substantial overhung load durability, and it provides quiet, but high continuous torque and yield ratings using heat-treated hobbed gearing and helical gears. It is available in 13 ratios from 5:1 to 300:1.
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.

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.
