We tested 20 solar generators to find the most versatile devices that can provide emergency backup power and fuel off-grid ...

Master Electronics provides availability of BK Precision’s 4075B series of arbitrary/function waveform generators. These devices incorporate a DDS architecture providing simple conventional function ...

With an ability to turn friction into small amounts of electricity, triboelectric generators may one day be used in clothes that turn movement into power, in battery-free brain implants, and a host of ...

Hydrogen! It’s a highly flammable gas that seems way too cool to be easy to come by. And yet, it’s actually trivial to make it out of water if you know how. [Maciej Nowak] has shown us how to do just ...

Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...
