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 ...
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 ...
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 ...
The classic crystal radio was an oatmeal box with some wire and a few parts. [Michael Simpson] has something very different. He found an assembled Philmore “selective” radio kit. The simple kit had a ...
