3D Printer tool changers are bedazzling to watch, but even failed attempts at tool changers can yield something marvelous. Such is the case for [Raymond] who transformed a tool changer attempt into a ...

The expansion of nanoscale optics has generated a variety of scanning probe geometries that yield spatial resolution below 10 nm. In this work, we present a physical model for coupling far-field ...

EMI from on-board DC-DC converters is a common problem with IoT products. These small circuits generally switch between 1 MHz and 3 MHz and use very fast sub-nanosecond edge speeds. The result is ...

An oscilloscope and a device under test (DUT) constitute a de-facto system. In it, the most overlooked element is the interface between the two: the oscilloscope’s probes. Test personnel simply grab ...
