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 ...

[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Take three rare Soviet-era germanium diodes, add a band-pass filter, and there you have it, the recipe for a limited edition hard-clipping distortion like no other, the Distortion Filter D312A When ...

Before the era of large-scale integration (LSI) semiconductor circuits, discrete logic circuits using the common diode-transistor logic (DTL) were still necessary and available in a format that was ...

This graphic depicts a new electronic device created at Purdue that uses germanium as the semiconductor instead of silicon. Germanium is one material being considered to replace silicon in future ...

(Nanowerk News) A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 - the purified germanium semiconductor - and now researchers here are on the ...

Materials science researchers have demonstrated the first electrically injected laser made with germanium tin. Used as a semiconducting material for circuits on electronic devices, the diode laser ...
