We note right away that "conductive pastes" in the literature are much more often called "conductive adhesives." This name is more accurate - because, in fact, the main thing in the installation is to fasten, glue the parts. And whether such glue will have the consistency of a paste or, say, liquid sour cream - this is a secondary matter.

And one more reservation: it is not necessary to think that electrically conductive glue should be used for installation of any details through which current should pass. Old, tested soldering is both simpler, more affordable, and cheaper. And that, perhaps the most important thing, solders are produced by industry, and electrically conductive glue has to be done in a handicraft way.

In any case, conductive glue should be used only when the material either cannot be brazed, or pickling before brazing is undesirable, or parts cannot be heated (which is inevitable during soldering) ...

Electric power generators. What is it? This is comfort. This is security. This is confidence. Confidence in yourself, in your home. The presence of a generator in your own home today will not surprise anyone. Today, a petrol or diesel generator is not a luxury - it has already become an urgent need. After all, with the loss of electricity, life in the house freezes - there is no water, there is no heat, there is no light ...

The power of generators used in everyday life ranges from 500 W to 100 kW. Generators of average power are most in demand - from 6 to 15 kW, about as much is necessary for the normal existence of medium-sized houses.

Almost all medium and high power generators are equipped with an electric starter, which greatly facilitates the operation of generators. To start work, just press the button or turn the ignition key and the station is ready for work ...

At school, we all studied algebra, but they did not talk about Boolean algebra there. What is the difference between Boolean algebra and school algebra, the history of its appearance, problems and applications are described in this article.

What is Boolean algebra? Oddly enough, despite the fact that for five years they have been studying algebra at school, many students, and later adults, will not be able to answer the question, what is algebra? Algebra is a science that studies the sets of some elements and the actions on them.

In a school course in algebra, such elements are numbers. Numbers can be denoted not by numbers, but by letters, everyone is familiar with this. In the first lessons of algebra, this always makes it difficult for many students. Remember how difficult it was at first to get used to adding letters instead of numbers, solving equations that say nothing.

Probably, each of us then asked ourselves the question: “Why do we need to enter letters instead of numbers and is it necessary at all?” ...

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 ...

The principle of operation, advantages, similar heating appliances.

Electric radiators with their appearance resemble water specimens. Heat is generated in them when electric current passes through the heating element of the radiator. It is this heat that warms us.

As you know, electrical energy can be quite easily controlled. Therefore, heating systems equipped with electric radiators make it possible to regulate the indoor climate.

As noted above, electric radiators are similar to ordinary ones both in appearance and in principle of operation. The difference is that instead of water, an electric current is used. In order to transfer heat from the heating element to the walls, various liquids are used, most often this is oil. Such radiators can be controlled both through a thermostat ...
