ELECTRONICS: Johnson Electric introduces Ledex® B12 Series Box Frame Solenoids. At just 2.0 (50.8 mm) x 1.25 inches (31.75 mm) the B12 are the company’s most compact linear open frame solenoids available to date. They are specifically engineered to fit where space is at a premium and to provide fast actuation times and high performance in applications where battery powered operation may be required. Pull versions are standard; push versions are also available.
B12 Series box frame solenoids weigh just 0.3 oz. (8.5 g), provide dielectric strength of 500 VRMS for one second with holding force of 7.7 oz. (2.1 N) at 20C, and provide 100 percent continuous duty cycle operation at 20C ambient temperature. A magnetically latching version will be launched later in 2010.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.

The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
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?
