In homes, offices, manufacturing, and basically anywhere, remote control switches can be useful. First of all, we are talking about lighting control. The advantage of this approach is undeniable, because personal comfort is very important for a modern person, no matter how cynical it sounds.

Switches with remote control over the radio channel, through an infrared remote control, with a motion sensor, voice command or just from a smartphone - all this is available today and is very wide. A person no longer needs to approach the switch whenever it is necessary to turn on or turn off the light, it is not necessary to reach for the button on the wall, it is enough to send a signal remotely. And all you need is to add a switch with a remote control to the lighting circuit. It is about such switches that will be discussed in this article, we will consider several models ...

Today it is hardly possible to surprise anyone with just a luminous sign or a bright light box with a painted picture. The consumer requires spectacles, and a static advertising image is rapidly becoming a thing of the past, giving way to dynamic displays and signs with running lights, iridescent letters, and in general, dynamics is replacing statics, and this is not at all surprising, because programmable LED controllers appeared on the market allowing it is easy to create unique lighting dynamic effects that, in combination with modern LEDs, are capable of creating real miracles of visualization.

A small controller box for signs at the request of the designer will revive the LED line, the composition of the LED duralight, or a large LED cluster - a block of individual LEDs or a block of entire LED lines. Solutions based on RGB LED clusters ...

When choosing an air heater, or just a heater, the first question is what type of heater to choose. After answering the first question, the necessary power of the device of the selected type is approximately calculated so that it can heat the room of the corresponding area. Approximately take 1 kW per 10 square meters. And finally make the long-awaited purchase.

But if in appearance all these steps seem simple and simple, then as soon as it comes down to the matter, a lot of nuances immediately pop up to the surface. What type of device to choose? What are the pros and cons of devices of one type or another? Which is best suited to current conditions? We will try to honestly answer these questions in this article. Namely, we compare the two most popular today, and at the same time completely different, such as air heaters - heating elements and ceramic ...

A brief overview of the functionality of the Schneider Electric Compact INS / INV Series products. What are switch disconnectors for? This switching device is primarily intended for switching rated currents in manual mode. The main difference between switch-disconnectors and circuit breakers is that they do not protect the circuits from emergency operation - overload and short circuit. What are the functions of these switching devices?

In this article, we briefly characterize the switch-disconnectors on the example of electric devices of the Compact INS / INV series of the well-known manufacturer Schneider Electric. The main advantages of this type of circuit breaker are its simplicity of design, wide range of applications, compliance with international standards, as well as the possibility of expanding functionality by installing various additional devices ...

Today, robotics is conquering ever-larger industries and is increasingly being introduced into various spheres of human life.And if earlier robots could fulfill the role of man, replacing him in factories, which often require uniform actions in the conveyor production, for example, in the production of cars, now the time has come when robots are able to be in every house to help people solve urgent tasks, and help save our time and effort.

Household robots designed to help a person in his daily life are gaining more and more popularity, which is not at all surprising, because the variety of robots is growing every year. Already today it includes vacuum cleaners, lawn mowers, window washers, pool cleaners, and even snow-removing robots. By the way, back in 2007, Bill Gates drew attention to the significant potential ...

Where can a beginner start mastering electronics? First of all, from a book, then moving on to practice, this can only be said by someone who does not yet know about the existence of the Electronics for Beginners set from Amperka LLC. The "Electronics for Beginners" set, which includes an electronic version of the book and an extensive set of electronic components, will allow a beginner to not only immerse himself in a boring theory, but will make it possible to immediately begin to implement the practical schemes that are given in the book, and the components for which are included in set.

The Electronics for Beginners set is sold in two parts, each of which contains all the necessary electronic components for assembling practical circuits and conducting the experiments described in the book by Charles Platt, which served as the basis for creating this educational set. The book in electronic form can be downloaded ...

In this review, we’ll talk about the Amperka educational kit produced by the Moscow Amperka LLC, which is a ready-made training course aimed at teaching beginners the application programming of microcontrollers and giving the student the opportunity to realize their creative potential by creating their own electronic devices. The set will allow a beginner to learn to put into practice the laws of electricity, as well as to master the practical application of theoretical material in computer science. The set is ideal both for schools and for independent development of Arduino.

The Ampreka set includes three components: electronics, a training course and online materials. The kit contains all the necessary electronic components, more than 150 parts that are useful for successful completion of the course. It includes resistors, LEDs, transistors, motors, sensors, an LCD screen, a board ...

This article will focus on stun guns. We will turn a little to history, then consider the technical side of the issue, and finally outline the factors that should be considered when choosing a stun gun for personal defense. On March 30, 1852, the German inventor Albert Sonnenburg received a patent for an electric whaling harpoon.

The device was intended for hunting whales, with the help of it the mammal was shocked by a dynamo generator on board the vessel to paralyze the whale and calmly catch it. For a hundred years, this was the only type of electric weapon - an electric harpoon for whaling, to which electricity was transmitted from a hand-held electric generator by wire directly from the side of the vessel. Nevertheless, the problem remained unresolved - the police of some countries fired too often during detention, and cases of unjustified killings ...
