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 ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

Electromechanical relays for testing products ranging from automotive engines to thermocouples are readily available, low-cost devices you can use to route signals originating from almost anywhere. It ...

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 ...

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 ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

In its first collaborative work with Hitachi Central Research Laboratory, researchers at the Advanced Technology Institute of the University of Surrey have show that superior transistor switching ...

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 ...
