Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

Learn how to build a DIY portable speaker using a car speaker, cardboard, and basic electronic components. This step-by-step ...

When you think of Sony, you probably think of a technology company that’s been around forever. However, as [Asianometry] points out, it really formed in the tough years after World War II. The two ...

Scientists have created an n-channel transistor using diamond for the first time, potentially leading to faster components that can work in extreme conditions. When you purchase through links on our ...

The telephone company had problems with vacuum tubes, too, and hoped to find something else to use for switching telephone calls. The idea of somehow using semiconductors (solid materials such as ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

“The first digital use of the transistor for consumers was in a calculator,” says Rick Bensene, curator of the Old Calculator Web Museum. Our series on the birth of the transistor — and with it, the ...
