Solid State Electronics

Solid state components are the building blocks of today's electronics. Learn about the technology inside the gadgets and machines that we use every day.

What does solid-state mean in relation to electronics?

Solid-state electronic devices are part of our everyday lives. The transistor, invented in 1947, was the first solid-state device to come into commercial use. Learn what solid state electronics are and where you can find them.

How Transistors Work

The introduction of the transistor moved the world from power-hungry vacuum tubes to portable, powerful solid-state electronics. What other advancements has the mighty transistor wrought on our society?

How Oscillators Work

Oscillators show up in lots of electronic equipment. In fact, you might be surprised to know that computers, radios, metal detectors and stun guns all use oscillators. Learn all about electronic oscillators.

How Inductors Work

An inductor is little more than a coil of wire. Sound simple? Well, it is -- but that coil of wire can do some pretty cool things. Learn all about inductors and what they're used for.

How Electronic Gates Work

Would you like to be able to build your own digital devices? Logic gates are the basis of digital electronics. Find out what these gates do and how you can use them to start building your own devices.

How Microcontrollers Work

Most modern electronic devices (TVs, appliances, power tools) contain an embedded microcontroller. It's basically a dedicated computer. Find out how these devices work and experiment with one on your own.

How Electric Motors Work

You might be surprised to find out just how much work is done by electric motors. They're everywhere! You'll find them in your car, your kitchen, bathroom, office... Find out how electric motors get stuff moving.

How Relays Work

Powered by electromagnets, a relay is simply a mechanical switch, and you’ll find them all over a typical house or car. Find out what these simple components are doing in all your electrical stuff.
