The company's newest single-axis controller/driver, designed for lower-cost network support, has communications options such as RS232, RS465, CAN and Ethernet. It allows CAN-using devices to work at the same time with a supervisory network that uses RS232, RS485 or Ethernet. It works well with the company's NEMA 17 and NEMA 23 frame I-Grade step motor/encoders. It comes with breakouts for power, communications and I/O. Its closed loop control (servo) of a stepmotor offers all the accuracy of a traditional servomotor, with better torque for applications up to 2,000 rpm. It works with only one cable for motor and encoder signals, and functions well on lines up to 50 ft. It comes with 12-48V dc input power, built-in voltage clamp and power resistor, four analog inputs, electronic gearing and camming, SSI encoder interface and many other features.
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.
