One of the perennial challenges of building robots is minimizing the size and weight of drive systems while preserving power. One established way to do this, at least on robots with joints, is to ...

Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but ...

High Performance HF Power meter using Arduino and a Directional Coupler This device can measure power over a wide dynamic range from 10uW to 1 KW and will derive SWR for a 50 Ohm load The front end ...

Abstract: When modeling magnetic components, the permeance-capacitance analogy avoids the drawbacks of traditional equivalent circuits models. The magnetic circuit structure is easily derived from the ...
