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 ...

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 ...

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 ...

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 ...

In a world obsessed with solar power there is still a tried-and-true power source that reigns supreme: the gasoline-powered generator. Advancements in technology have made these machines smaller, ...

Cars use a type of a.c. generator, called an alternator, to keep the battery charged and to run the electrical system while the engine is working. A dynamo is another type of generator sometimes found ...
