Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick ...

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 ...

This DI describes how some simple circuitry can simulate bouncy contacts, and do so controllably and repeatably, thus ...

The F2 Ultra is an interesting machine as it combines two laser types in one enclosed engraver. The first is a powerful 60W MOPA fibre laser used for engraving, embossing and cutting thinner metals, ...

The alternator is a device that keeps your car’s electrical system running once the engine is on. It’s essentially a small generator that converts mechanical energy into electricity, bolted to the ...

The STARFIRE Hub – an initiative funded by the US Department of Energy to develop fusion energy solutions under the leadership of Lawrence Livermore National Laboratory (LLNL) – is pleased to announce ...

Paul Crump, head of the High-Power Diode Laser Lab at the Ferdinand-Braun-Institut (FBH) in Berlin, will lead the newly ...

Heat, in particular, can cause these components to quickly break, so installing an LED bulb in a hot corner of your home or in a deep-set socket with poor ventilation can cause the lights to go out ...

Biology and quantum physics often seem like they belong to separate worlds. Living cells function in warm, noisy environments ...

Series 600 high-voltage reed relays from Pickering Electronics offer over 2500 combinations of rating and connection options.

In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and ...

The LGM-35A Sentinel has run into severe cost overruns and schedule delays that could force the Air Force to keep Minuteman ...
