This is a simple fire alarm circuit using Germanium Diode and 555 timer. In this circuit Germanium Diode plays very important role in detecting the fire.This is a simple fire alarm circuit using ...

Scientists at GE Global Research have developed one of the most fundamental devices within an electronic circuit using carbon nanotubes, which many semiconductor researchers think will replace ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

Niskayuna, N.Y.-based General Electric Co.’s Global Research organization reported today its researchers have developed an “ideal” carbon nanotube diode that operates at the theoretical limit, ...

Beyond the power variant, it sometimes seems as though we rarely encounter a discrete transistor these days, such has been the advance of integrated electronics. But they have a rich history, going ...

CTC soups up its Dumble/K-style amp-in-a-box drive with some super rare germanium. It's limited edition, on until it's gone, but the original Unobtanium will remain on the menu When you purchase ...
