Why was the transistor such a big deal? Until the late 1940s, electronics relied on vacuum tubes, glass bulbs that used a delicate filament inside a vacuum to moderate the flow of electrons. Vacuum ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

The history of the transistor and similar types. How transistors made an impact on the world. How grudges eventually subside. Transistors are simple electronic devices that boost or switch electrical ...

A limiting problem in creating energy-efficient circuits for improved memory and more powerful computers is manufacturing a transistor with reconfigurable properties. As the size of transistors ...
