Do you know what a Typotron is? (ART565E)

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”.

Energy Storage Technologies (ART561E)

In the past, the only simple and most used way to store energy was through batteries. Batteries have evolved, allowing ever greater amounts of electrical energy to be stored, but at the same time new forms of energy storage have been created, improved and are now very promising, some with important practical applications. In this article, we focus on these technologies and with special attention to their application with forms of energy generation which also evolve day by day, such as solar and wind power.

Back to the Future (ART423E)

With advances in technology, especially those involving quantum physics, we are increasingly realizing that a time travel may be possible in the future. Maybe it is not the way the well-known film "Back to the Future" preaches, as we're just crawling into the understanding of its phenomena. But there is something behind it. In this article we make some interesting considerations on the subject.

Makers, Inventors or Scientists (AT546E)

We are experiencing a strong transition in the way of life for people all over the world, accelerated by the pandemic that is plaguing us at the time of writing this article. There will be a disruption, in which our old customs will be totally forgotten, and we will move on to a new era in which customs will be different. In this article, we focus on what, in our view, this will mean for science and technology.

Designing a Plasma Speaker (ART421E)

The plasma speaker or ionophone is not a new idea. The “singing arc” was invented by William Duddell in 1900 and then the ionophone by Sigmund Klein. We have not yet reached a sufficiently efficient version to be marketed, but curious readers can conduct experiments and even demonstrations at events with the ideas we give in this article.
