Zener Diode

Zener diodes are diodes that have a very unique property that makes them eminently useful in many different electronics applications. These devices are much different than a standard diode, which is also one of the most common and useful electronic components in the world. Zener diodes are much different from a standard diode in terms… Continue reading Zener Diode

Fibre Optic

Fibre optic is a technology that allows light to be guided through a cable, providing illumination, data transmission and other functions. It is among the most efficient ways to transmit data in the world, allowing data to be transmitted over very long distances at significant bandwidths. Fibre optic has largely displaced many other technologies used… Continue reading Fibre Optic

Relays Overview

What Is a Relay? A relay is a type of switch that is controlled by an electrical circuit rather than by a human operator. These devices are among the most common of all electrical components and they come in a wide variety of designs. Relays first came about as the result of telegraph technology. They… Continue reading Relays Overview

Control Relays

Relays are among the oldest and most heavily used electronic components in the world. The most common design for a relay is that of an electromagnetic switch that can change its open or closed state with the application of a current to a coil. Relays are commonly used to isolate circuits, particularly in cases when… Continue reading Control Relays


What You Need to Know about the Raspberry Pi The Raspberry Pi is a credit-card-sized computer that plugs into a TV and a keyboard and is a capable little PC that can be used for many of the things that a normal desktop PC does, like spreadsheets, word-processing, and games. It also plays high-definition video.… Continue reading RASPBERRY PI

Chip Systems

A chip system, or a system on a chip (SOC), is an integrated circuit that places all of the various components of an electronic system or computer system into just one chip. You will find these most often in embedded systems. Some of the systems will run only a single system, while others are capable… Continue reading Chip Systems

What is a Microphone?

Microphones are incredibly common electronic appliances. They are utilized in telephones, on headsets for computers, in hearing aids, in tape decks, in megaphones, for VoIP purposes and much more. Microphones work on very well understood electrical principles and are actually very old devices. Depending upon what you actually consider a microphone, there are varying ways… Continue reading What is a Microphone?
