The Parts of an X-Ray Machine There are three main parts of an x-ray machine. The first is the x-ray tube. This is responsible for the creation of x-rays. Therefore, without this functioning properly, there would be little chance for the x-ray to work in the right way. It generates enough x-rays so that when they are sent toward the body, they are able to read what the doctor needs. The next element is the high voltage power source. This is important because there are a lot of components that Read More

A device's range is sometimes not large enough to cover an entire infrastructure. Fortunately, WiFi repeaters can be used to effectively double the Read More

Embedded systems refer to devices, instruments or large engineering structures/systems that are built to handle one or a few pre-established tasks. The computer controlling the whole thing is built into or 'embedded' within the device. Cellphones and personal digital assistants (PDAs) are examples of devices with embedded systems. They both perform a specific number of tasks which are controlled by a built-in computer system. Inertial guidance systems used for aerial navigation or as part of the guidance package of smart bombs and missiles are examples of instruments with embedded systems. Read More

Electroluminescent wire (EL wire) is a thin wire that produces 360 degrees of visible light. EL wire differs from string lights, such as Christmas lights, which only produce light at specific points. It uses a phenomenon known as electroluminescence to generate light when electricity runs through it. EL wire is very thin and flexible and can therefore be used in various ways, especially decorating. How to Make EL Wire A thin strand of copper that is coated with a layer of phosphor is the first piece of material used to Read More
