When planning an overhaul of an apartment, the question arises of choosing lighting equipment. I would like to introduce some kind of innovation, a twist. There is a great alternative to traditional lamps - LED strip. Installing LED strip on the ceiling will radically change the overall appearance of the whole room. At the same time, great opportunities open up for you in choosing the best design solution. You can choose either a single color tape or a three-color one, that is, an RGB type tape.

Among the advantages of using LED strips can also be noted the ability to adjust the brightness of the lighting, as well as the speed of color change. You can choose the lighting for any mood and your surroundings. In addition, for the installation of LED strip, you do not need to call specialists, since it can be easily mounted and connected independently. This article will talk about how to install ...

Electricity has firmly entered our lives. While it is, we do not notice it. It seems that this has always been and will be, but if he faces the abyss, and we understand that this is a problem. Especially when a power outage occurs without warning.

The lights go out, the TV and computer turn off, you have to adjust your plans, and in addition to this, eliminate the consequences, starting with the search for candles, flashlights and matches and ending with a leaky refrigerator and spoiled foods.

This problem was especially urgent in the 90s of the last century, when there were so-called rolling blackouts. Now there is no planned shutdown - the phenomenon is much more rare. Nevertheless, it occurs and spoils life. All power outages have two types of causes: technical and economic. Technical reasons. Scheduled major or current repairs of the entire electrical household ...

Very often, the problem arises of failure of the charger of a mobile phone or other device, which is used to charge the battery charger. The main reasons why the charger may fail are as follows: wire breakage, failure of the charger unit, violation of the contact connection of the wire with the plug or charger unit.

Very often, the cause of the failure of the charger is a wire break or a violation of the contact of the wire with the structural elements of the charger - plug and block. In this case, you can repair the charger yourself. Consider the principle of repairing damage to the charger wire using a specific example of repairing the charger of a Nokia mobile phone (with a thin plug). To repair the charger we need: a multimeter, a knife, a soldering iron ...

The problem of finding alternative methods of heating apartments and houses does not lose its relevance. One of the modern solutions for space heating is the installation of infrared films. All their advantages are described in detail by sellers of such products.

We give a specific example of the use of this type of heating. The owners of a three-room apartment building, it was decided to heat their home using infrared films. They turned to the appropriate company, whose specialists performed the installation and commissioning of the necessary equipment.

A temperature controller was installed in each room to control the temperature. The heating performance was tested, the owners performed the calculation, and the company employees left.After a short period of using infrared heating, a serious problem arose. The fact is that the power of a meter of a square heating film is 250 W ...

There are many transistor circuits (just remember the number of at least household equipment) for amplifying and converting electrical signals, but, with all the diversity, these circuits consist of separate stages, the basis of which are transistors. To achieve the necessary signal amplification, it is necessary to use several stages of amplification, connected in series. To understand how amplifier stages work, you need to become more familiar with transistor switching circuits.

The transistor alone cannot amplify anything. Its amplifying properties are that small changes in the input signal (current or voltage) lead to significant changes in voltage or current at the output of the cascade due to the expenditure of energy from an external source. It is this property that is widely used in analog circuits - amplifiers, television, radio, communication, etc. To simplify the presentation, we will consider here...

The type of circuitry by which the LED strip is connected depends on several factors: the length of the strip and its type. As a rule, the standard length of the LED strip is five meters. By the type of tape are classified as monochrome and RGB tape. Let's consider the connection schemes for single-color LED strips.

When purchasing a power supply for an LED strip, pay attention to the correspondence of its rated power to the power consumption of the LED strip. If you plan to connect several LED strips, then accordingly choose the power supply unit whose rated power is slightly higher than the total power consumption of both strips. When choosing a power supply, always make a small margin of power. Connecting one tape of a standard size (5 meters) is quite simple. To do this, connect the tape to the power supply ...

A few recommendations regarding the choice of power supply for powering LED strips. A brief overview of several of the most popular power supplies for powering LED lighting.

Lighting equipment in our time has a large assortment. Currently, the buyer is presented with many modern developments in the field of lighting equipment, in particular LED lighting (LED strips, lamps, lamps). If you decide to use LED strips in the design of your apartment, then you should know some features.

One of the features is that you cannot directly connect an LED strip to the network, such as a conventional incandescent lamp or housekeeper. This is due to the fact that the operating voltage of the LED strip is much lower than the voltage of the household network, as a rule, this is 12 V ...

For wiring of a hidden type, as a rule, it is necessary to install sockets of the corresponding type, that is, hidden. Very often there are external outlets in the apartment. Perhaps, when installing the wiring, the previous owner of the apartment or an electrician performing work to replace the wiring decided to save his time and installed an outdoor type socket. He greatly simplified the work, since he did not have to mount the box directly into the wall for mounting a hidden socket.

The external outlet does not fit into the interior design of the apartment, since its entire body is located outside the wall.At this stage, the landlord decides to fix this problem and install a hidden socket, that is, an internal one. How to replace an external outlet with an internal one? First, you need to prepare for the work ...
