B&K Precision'sModel 1673 has a quad digital display,
which enables the user to visually monitor the output voltage and current on
both variable outputs simultaneously. The 1673's two variable outputs, configurable
from 0 to 32V dc, and one fixed output of 5V dc provide clean power. The two
variable outputs can also be used independently or interconnected in either
series or parallel configurations for greater output voltage or current
supply can be set via the front panel to provide constant voltage (CV) or
constant current (CC) operation with automatic crossover. This feature allows
for continuous transition from either constant current to constant voltage mode
in response to any load condition changes with a front panel LED indicator to
indicate which mode is active.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
