If you haven’t seen them before, they usually have some kind ... an inductor, a diode, or a transistor and get a readout of which pin is which. It seems like magic, but [Andreas Spiess] did ...

Op amps. Often the first thing that many learn about when beginning the journey into analog electronics, they’re used in countless ways in an overwhelmingly large array of circuits. When we ...

That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology. It was built by Walter Brattain. Before ...

The microprocessor's investors pulled out before it was built, thinking it was a waste of money. The transistor and its offspring have consistently been undervalued -- yet turned out to do more ...

Scientists in the US built the first silicon transistor in 1947. Before that, the mechanics of computing had been performed by vacuum tubes, which were slow and bulky. Silicon changed everything.
