The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

FIFTY years ago today in Murray Hill, N. J., a Bell Labs engineer named Walter Brattain connected two strips of gold foil to a thin piece of germanium and noted with satisfaction that this combination ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

Fast switching: the Hybrid Photonics Labs at Skoltech where the new optical transistor was created. (Courtesy: Skoltech) A new optical transistor has been designed by researchers in Russia, ...
