Wireless Charging and Electric Vehicles

In our daily lives, we are increasingly using wireless products. At the same time, researchers are also working on newer trends in charging electric vehicles wirelessly. With more countries now implementing regulations for fuel economy and pushing initiatives for replacing fossil-fuel based vehicles with those driven by electricity, automotive manufacturers have focused their targets on development of electric vehicles. On one hand there are technological advancements on lithium-ion batteries and Read more [...]

What is Raspberry Shake and BOOM?

The Earth below our feet is never still. Although we feel tremors only when they are substantially strong, such as during earthquakes, we can use the highly popular single board computer, the Raspberry Pi or RBPi to monitor what is happening just under us. This tiny seismograph, with an appropriate name of Raspberry Shake, is the smallest one can find. Although small, Raspberry Shake can record earthquakes of all magnitudes, even those no human senses can detect. It is also capable of recording Read more [...]

What are RTUs – Remote Terminal Units?

Nowadays, small computers make up remote terminal units or RTUs and SCADA units. Users program controller algorithms into these units, allowing them to control sensors and actuators. Likewise, they can program algorithms for logic solvers, power factor calculators, flow totalizers, and many more, according to actual requirements in the field. Present RTUs are powerful computers able to solve complex algorithms or mathematical formula describing external functions. Sensing devices or sensors gather Read more [...]

Lighting for Illumination and Indication

In our industries, lights play several important roles. Primarily, industries tend to use lights for two fundamental purposes—illumination and indication. Smart visual factories use lighting intelligently. They carefully differentiate between using it for illuminating devices and for indicating them. Fixtures for illumination light up a space in the industry, improving productivity, worker ergonomics, and enhancing safety. For instance, in huge storerooms, low bay lights illuminate areas blocked Read more [...]

How do Surge Trap SPDs Work?

Surge trap Surge Protection Devices or SPDs are protection devices to absorb high-energy power spikes that could damage sensitive electronic equipment such as process controllers, instrumentation, and computers. They divert high-energy power away from an appliance by providing a low-impedance path to the common point earth ground. Frequently, panel boards use several metal oxide varistors or MOVs, connected in parallel, to act as surge suppressors or traps. AC surge suppressors most commonly use Read more [...]

Ethoscope with the Raspberry Pi

Although ethoscopes are very popular instruments for detecting or recording the real-time activity of fruit flies, they can potentially be used on other animals as well. The ethoscope platform is actually a collection of interconnected tools that biologists use when designing experiments, to capture and analyze huge amounts of behavioral data. The ethoscope uses a free and open-source set of tools, both hardware and software. The hardware is a Raspberry Pi (RBPi) while the software is built on top Read more [...]

Do It Yourself Blynk Board

Those who have some experience with Do It Yourself (DIY) electronic projects, and are just starting to test the waters in the Internet of Things (IoT), the Blynk Board from SparkFun is an activity filled challenging exercise. Both experienced users as well as beginners will find this fun to set up and learn—the kit comes with more than ten projects. Of course, you can make this board work without the IoT Starter Kit from SparkFun, but then you will have to buy the sensors and other components Read more [...]

A New Magnet for Electric Cars

The advent of electric cars is spawning innovations in almost every technology field including batteries, motors, wires, PCBs, electronics, and many more. Electric cars require powerful and efficient motors, and for that, magnets used in the motors must be stronger than usual. Toyota Motor Corporation has developed a new magnet for electric motors, and they have reduced by 50% the use of critical rare-earth elements they were using so far. As the number of electric cars is set to increase rapidly Read more [...]

Things Gateway Ties IoT Devices Together

Project Things from Mozilla is a framework of software and services. It helps to bridge the communication gap between IoT devices. Project Things does this by giving each IoT device a URL on the web. The latest version of the Things Gateway, also from Mozilla, can directly let you control your home over the web, and manage all your devices through a single secure web interface. Therefore, if you have several smart devices in your home, you will not need different mobile apps to manage each of them. Read more [...]

Raspberry Pi Makes the Pac-Man Game Go 3D

Some avid gamers of today are not even aware of the video games that flourished in the seventies and the eighties. Those who have a collection of retro games may have given their children time to catch up with the old games. One such classic game from the 1980s, a very addictive one, was the pellet-guzzling arcade game with the name of Pac-Man, from Namco. One of the youngsters, Emanuele Coletta, has come up with a 3-D rendition of Pac-Man. Emanuele wanted to make something funny, while at the same Read more [...]
