Over on YouTube our hacker [VIP Love Secretary] shows us how to make a simple MOSFET tester. This is a really neat, useful, elegant, and simple hack, but the video is kind of terrible. We found ...

After my DIY article “Build Your Own Headphone Amp” in the May 25 issue, the good folks at Radio World asked me to share the process by which I make printed circuit boards. There are usually two ...

According to the most recent data from the World Bank, 15 percent of the world’s population—approximately 1.1 billion people—lacked access to electricity in 2014. In 1994, approximately 27 percent of ...

Op amps are typically used to build signal processing circuits like amplifiers, integrators and oscillators. Their functionality can be described by mathematical formulas that have a single, ...

The idea of a circuit board that dissolves the moment it is cooled totally sounds like something out of the Mission: Impossible movies, or maybe a mystery heist flick where a rare computer disappears ...

A team of researchers from the University of Arkansas has successfully developed a circuit that can capture the thermal motion of graphene and convert it into an electrical current. The physicists say ...

Johns Hopkins researchers have discovered new materials and a new process that could advance the ever-escalating quest to ...

Australian researchers have announced the manufacturing of a quantum circuit at an atomic scale, claiming it integrates all the necessary components of a classical computer chip but at a much, much ...
