New ways of generating energy have been presented to the world constantly, some very curious. However, just as important as the ways to generate energy are the ways to store it. Batteries, supercapacitors, and others have been constantly improved. The hot topic was also the focus of Professor Ventura, Bart and Bert. In fact, it went far beyond what the three expected becoming a subject of national discussion when starting from a simple bet on an innovative idea, spreading across the world as a technological shock wave. See more in this adventure of Professor Ventura, Bart and Bert how they discovered a way of being to store energy in a hole.
In the previous article, we discussed the differences between solid-state contactors and solid-state relays (SSR and SSC). We have seen there are some doubts about the point at which one type of component is distinguished from the other. However, if we consider that basically the two control currents (which can be intense) from an electrical signal, we can explore the common points of these devices with some circuits that we have selected.
There are dozens of types of capacitors that we find in electronic circuits, with the most diverse purposes. Technicians almost mechanically know how a capacitor works in a given application and when to replace them, but certainly few are the ones who stopped to analyze how these small devices store energy. In this article, we will address this interesting subject of interest to beginners, students and technicians.
For the month of June of this year (1994), scientists foresee a gigantic cosmic collision, which can even affect in some way, we do not know how, life on Earth: a shattered comet must hit the planet Jupiter, at a fantastic speed of 150 thousand kilometers per hour. Even occurring a few hundred million kilometers from Earth, this event has a special meaning for us and even for electronics. In this story, Prof. Ventura explains to his friends Bart and Bert the "electronic" side of this fantastic celestial impact.
The "zoology" of electronic components presents very interesting facts for readers who are interested in "archaeological studies" of this science. Not only what certain components did is interesting, many of which disappeared, but also the assigned names that followed a certain logic. We have already dealt with other articles on components ending in "tor" and we see that a large number of them have not reached our times. In this article we deal with components terminated in “tron”.
The Internet of Things (IoT) is undergoing a very fast development phase, accelerated by the needs created by the disruption which represents the pandemic. In fact, the changing habits of all of us, with the creation of new products, has a very intense focus on the internet of things, and this involves the presence of wireless technologies. In this article, we make some considerations about the existing network technologies and how to choose the best one for your business.
