First-person-view (FPV) flying, by adding a camera, video transmitter, and video goggles to the meat on the ground, is one of the best ways to experience remote-controlled flight. For just a few hu… ...

A fully fledged spectrum analyzer on a basic Arduino board? It is possible when the software is tailored to the available processing power. A standard Arduino can be turned into an AC line (‘mains’) ...

Precise optical spectrum analysis with high resolution by an economical and reliable device is of much interest in optical science and technology. In this work, we propose a silicon-photonic ...
