Stylus: The Future of the Electronic Pencil?

So far, people have been rather disappointed in using Electronic Pencils (styluses) for the purposes of taking notes on their smartphones. However, a new combination of the MyScript Nebo note-taking app and the Apple Pencil on the iPad Pro seems like a winner. This is really helpful to people who are coming up with ideas at odd times of the day, and have to look for a piece of paper and pencil to jot them down. The trouble with the paper and pencil approach is eventually every hand-written note Read more [...]

What is a QLED?

Recently, Samsung has announced their new TV technology using QLEDs to counter the OLED TVs that LG and others have put on the market. QLED stands for Quantum dot LED, and though Samsung has been using the concept of quantum dots in its TVs for quite some years now, they claim they will be bringing out several flavors of the QLED technology. According to Samsung, QLEDs are transmissive, as LCDs are, and light goes through several layers to create an image on the surface of the screen. The company Read more [...]

Multicolored LEDs Create Secondary Colors

Any student of physics knows mixing two primary color light sources produces a secondary color. For instance, mixing the primary colors red and green creates the secondary color yellow. There are three primary colors—Red, Blue, and Green. This process is easily seen in tricolor and RGB LEDs. There is a disadvantage in this method. As two primary colors are necessary for generating a secondary color, two LEDs must remain turned on at the same time. Therefore, generating a secondary color means Read more [...]

The Law, Big Data, and Artificial Intelligence

We use a lot of electronic gadgets in our lives, revel in Artificial Intelligence, and welcome the presence of robots. This trend is likely to increase in the future, as we continue to allow them to make many decisions about our lives. For long, it has been a common practice using computer algorithms for assessing insurance and credit scoring among other things. Often people using these algorithms do not understand the principles involved, and depend on the computer’s decision with no questions Read more [...]

What is a Programmable Logic Controller?

Programmable Logic Controllers (PLCs) are miniature industrial computers. The hardware and software in a PLC are meant to perform control functions. Specifically, a PLC helps in the automation of industrial electromechanical processes. This includes controlling machinery on assembly lines in a factory, rides in an amusement park, or instruments in a food processing industrial establishment. Most PLCs are designed to facilitate multiple arrangements of analog and digital inputs and outputs. They Read more [...]

Different Types of Industrial Cables

To wire up different components within electronic gadgets, hook-up and lead wires may be adequate, but the electric industry needs a vast variety of industrial cables to remain connected. Chief among these are power cables to carry high voltages and currents, and cables necessary for industrial automation and process control. Cables may conform to multiple standards such as UL, CSA, and others. Cables often have to transmit power or signal in industrial environments that may harbor the harshest conditions Read more [...]

What Influences Industrial Connectivity?

In the industry, any component coming in the path of delivering control signals or power to do useful work is termed industrial connectivity. For instance, components including relays, motor starters, terminal blocks, and connectors are all typical connectivity components. Generic connectors can use low-cost material as they merely maintain electrical continuity. However, based on operating environments, connectors are differentiated into four categories: hermetic, military, industrial, and commercial. Read more [...]

Importance of Resolution in Thermal Imaging

Thermal imaging technologies have long been associated with a range of applications and industries for discovering abnormalities and weak points quickly and efficiently. These technologies are ideal for production monitoring and other applications as materials and components undergo non-destructive testing under operating conditions. That allows discovery of the problem before a breakdown can occur or a fire risk can develop. For instance, thermal imaging allows contractors in a building, facilities Read more [...]

What are Miniature Circuit Breakers?

Most places that earlier used fuses in low voltage electrical networks now commonly use miniature circuit breakers (MCB) instead. Although an MCB is much larger than a fuse holder is, the MCB has several advantages when compared to fuses. Any abnormal condition of the network, meaning overload or fault conditions, causes the MCB to sense and automatically switch off the electrical circuit. While a fuse does not sense it, the MCB senses the abnormality in a more reliable way. Additionally, the Read more [...]

LCD Touchscreens for the Raspberry Pi

Those using the single board computer, the Raspberry Pi (RBPi), can now get several high-resolution LCD screen models on the market. While they are cheap, some are designed to integrate with the RBPi specifically. SunFounder, a company specializing in accessories and kits for RBPi and Arduinos, produce a series of these screens. For satisfying different segments in the market, SunFounder has lately produced and is marketing a number of models with varying price ranges. SunFounder LCD 10.1” HD With Read more [...]
