Lightning is one of the most powerful forces of nature and lightning strikes can cause a lot of damage. When lightning strikes, it creates a high voltage discharge that emanates from the cloud in the form of lightning bolts. These lightning bolts can reach as far as 10 miles to strike something on the…
Image Source: Flickr When it comes to connecting a monitor, laptop, or other video devices to your computer there are plenty of different cable types and connectors to choose from. Which one should you use? It all depends on the features that you need, but also how much space you have available and what kind…
Image Source: Flickr When you think of electricity and circuits, what comes to mind? If you’re like most people, you’ll probably think of series and parallel circuits. After all, these are the two most common types of electric circuits used in everyday devices and appliances. But how do they differ? Which one is better for…
If you’ve ever studied electronics, you may have heard the term “buck converter”. It sounds like something that only an electrical engineer could understand, but it’s actually quite simple to understand. You see, a standard DC motor has a voltage range of around 3 volts up to 24 volts or more. But that does not…
The cathode ray oscilloscope is a piece of laboratory equipment that may be used to examine the waveforms of alternating currents and voltages and measure voltage, current, power, frequency, and nearly any other variable involving amplitude and waveform. The screen displays the amplitude of electrical signals as a function of time. It’s commonly used for…
Standard wall switches provide simple on-off control of light fixtures. On the other hand, Dimmers allow you to alter the amount of power a fixture receives, changing the lighting intensity. A rheostat—a big variable resistor—was used in older dimmers. As the rheostat’s resistance grew, the voltage to the lamp was reduced, and the energy that…
A network switch serves as the system’s ” brain when it comes to network design. ” Networking hardware connects all devices on a LAN (Local Area Network) and redirects and forwards data to the correct location. When it comes to running a business, it’s critical to have a network switch that can successfully meet all…
The ATtiny85 is an 8-bit RISC microcontroller that is widely popular. Because of its great functionality in such a compact size has become the primary choice for professionals and developers. It’s an 8-pin (PDIP) microcontroller with nearly all of the functionality that any microcontroller should have, including built-in FLASH, EEPROM, SRAM, SPI, IIC, ADC, etc.…
Video cards and graphics cards are two of the most important pieces of hardware in your computer. They’re both used for rendering images on your screen, but they do it in slightly different ways. However, both video cards and graphics cards serve the same general purpose: to help improve visual performance by providing the computer…
Computer networking is a complex world. There are endless combinations of protocols, standards, and other variables to consider when building out your home or office network. And if you’re like most people, you probably have no idea what half of those things mean. Fortunately, it doesn’t have to be that way. To get the details…
