How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

After seeing many projects that use microcontrollers to switch mains voltages [Rob Miles] decided to share his preferred method. The shots you see above are an enclosed relay, part number RIBTU1C ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

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 ...

MIT engineers built a magnetic transistor from chromium sulfur bromide, promising smaller, faster electronics with built-in ...
