Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Electromagnetic waves with frequencies between microwave and infrared light, also known as terahertz radiation, are leveraged ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

Rarely a week goes by that some company doesn’t offer to send us their latest and greatest laser. You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the breeze, and no ...

The diode is one of the most commonly adopted and simply made elementary component in semiconductor technology. It’s been the basic starting brick for the construction of all electronic technology, ...

Hobbyist-grade laser cutters can be a little restrictive as to the types and thicknesses of materials that they can cut. We’re usually talking about CO 2 and diode-based machines here, and if you want ...
