The article describes the most common devices for protecting your electrical equipment from voltage surges. The advantages and disadvantages of voltage stabilizers are considered.

Our power networks have been in a rather neglected state for more than a dozen years, as a result of which multiple accidents occur, which leads to the failure of household appliances.

A lot of equipment designed to protect electrical appliances is presented on the electrical equipment market. Consider only the most common devices that will help protect our devices from voltage surges.

High and low voltage protection. These devices are designed to protect both individual consumers (TV, computer, refrigerator), and the entire apartment as a whole ...

Warm floor. What is it? This is comfort, coziness, profitability ... The article gives some tips and recommendations from an electrician with experience. Read it, think it over and you will understand whether you can build a “warm floor” on your own ...

Today, there are several types of heating systems of this type - this is a cable system where a cable is used. Cable thickness from 3 to 10 mm. For ease of installation, some manufacturers make systems in the form of mats. And the second type is the so-called “warm” or “heating film”, which we will talk about in the next article.

So, how do you build a warm floor on your own? Is it possible? What is needed to know and be able to do this? Here are some simple tips that you can use to achieve the desired result ...

An article about various ways to connect the load to the control unit on microcircuits using relays and thyristors.

All modern equipment, both industrial and domestic, is powered by electricity. At the same time, its entire electrical circuit can be divided into two large parts: control devices (controllers from the English word CONTROL - to control) and actuators.

About twenty years ago, control units were implemented on microcircuits of small and medium degree of integration. These were the series of chips K155, K561, K133, K176 and the like. They are called logical digital circuits, as they perform logical operations on the signals, and the signals themselves are digital (discrete).

The operation algorithm of such control units was carried out due to the corresponding connection of microcircuits, and their number was quite large. Currently, all control units are developed on the basis of different types of microcontrollers ...

Features of the device of organic LEDs and prospects for the development of OLED technology.

For light signaling, LEDs have been used for a long time. Currently, the production of LED lamps used for lighting is actively developing. Their advantages are obvious: high efficiency, long service life, low power consumption. Now a new direction is beginning to gain momentum - the production of organic LEDs.

Organic light-emitting diodes are a set of films of organic origin, which, when passing an electric current, begin to glow. In this case, the light is distributed evenly over the entire area of ​​the material ...

The development of human thought has led to the emergence of various devices designed to simplify our lives.However, this to some extent pushed humanity closer to that dangerous line beyond which the harm caused by the device will exceed its benefit.

Electricity is the driving force of the entire modern process of life; many vital systems cannot do without it. Nevertheless, many people die or receive damage from electricity. Therefore, we can conclude that a characteristic feature of the development of power supply and power consumption is electric injury.

Injury has become a social phenomenon and is the subject of study not only of medicine alone. The problems of preventing and eliminating injuries should be addressed mainly by organizational and technical measures ...

The article describes a converter circuit made on a modern element base, containing a minimum number of parts and allowing to obtain significant power in the load.

For many years now, on the pages of radio engineering publications, circuits have been published that make it possible to obtain an alternating voltage of 220V from a car battery to power various equipment in “field” conditions.

The modern elemental base allows us to significantly simplify such schemes. The proposed scheme, in comparison with the just described, contains a minimum number of parts ...

Brief installation instructions for plastic skirting boards with cable channel.

Installation of skirting boards is a joyful moment of repair, as it is its final stage. Skirting boards vary in the material from which they are made. “Classics” are wooden skirting boards, but wood-based skirting boards from MDF and also from plastic are produced.

Recently, plastic skirting boards with a cable channel, in which you can lay a telephone or network cable, with the possibility of replacing it without dismantling the skirting board, have been very popular. All fasteners (screws or nails) are inside it.

The cable channel is closed with a decorative panel that masks the channel itself, together with fasteners ...

What to do if the light goes out in the apartment? The article gives a brief description of the troubleshooting procedure in the power supply system of an apartment, a private house by those who have never done this — single boys and girls, men and women who do not have special education.

The lights went out - and immediately a lot of problems: how can I watch the series, in the morning - a bath, a toilet, a hairdryer? Let's try to help ourselves. The first thing you need is local lighting: a flashlight, a mobile phone, a lighter, in a pinch, a candle, matches. The best thing now is the LED flashlight, which is mounted on the head - very comfortable and hands free.

Now let’s determine how the light is off: in the whole apartment or in one room ...
