The smart grid is the next evolution of the electricity grid with the convergence of electric power, telecommunications infrastructure and information technology. The ultimate goal is to allow ...

These days when electronic circuits can be found almost anywhere, there is, some people fear*, a different kind of environmental pollution. They call it electrosmog (the word does not appear in any ...

This circuit can easily be assembled on a small piece of prototyping board. Use low-current types for the LEDs. They have a low forward voltage and are fairly bright at current levels as low as 1 mA.

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Researchers have co-opted glucose meters to detect infectious agents, including SARS-CoV-2, by pairing the devices with synthetic gene circuits that produce glucose in response to target analytes. The ...
