If you have not heard about the COCO home appliance remote control technology, then it's time to get to know it! After all, this is the most affordable and simple system for radio control of electrical appliances and "smart home".

The heart of the simplest version of the system is the AYCT-102 remote control. It contains a radio transmitter operating at a frequency of 433.92 MHz and allows you to control both individual electrical appliances plugged into sockets through radio adapters, or lighting, using miniature built-in receivers, and groups of electrical appliances. For example, simultaneously with several electric blinds or a group of spotlights located in different parts of the site.

The AYCT-102 remote control is designed to operate on 16 channels, divided into four subgroups. This makes it very easy to manage appliance groups ...

A person cannot perceive with his senses: the rustle of electrons running through wires, see the speed of their movement, smell them. We cannot detect electrical energy without special devices, but it can cause great harm to our body. Indeed, a current of 0.05 amperes, with a tragic set of circumstances, causes cardiac fibrillation.

Manufacturers of electrical equipment with energy supply organizations do a lot for the safe operation of electricity. However, it also depends on the owners of the apartments. An example from the life of children. A little boy walked around the room, holding a female hairpin in his hands - an ordinary steel wire. In front of my parents, I stuck it into the openings of the electrical outlet so quickly that they did not have time to react. What happened ...

Everyone knows that the fugenfueller is ideal for leveling walls, sealing joints of drywall sheets, filling various cracks and grooves in the walls, as well as sealing strobe when laying hidden electrical wiring.

Everyone knows that the surface of the walls before puttying must be cleaned of dust. But there are at least two mistakes that even experienced professionals make when using this wonderful material.

The first mistake is made when sealing large grooves and strobe with electric cables having a depth of 15-25 millimeters. Trying to save time, they close the stroba immediately to “zero”, filling the entire volume of the cable groove. When dried, the fugenfueller increases its volume and along the strobes there is a tubercle 2-3 mm high, which in a day to clean off is already very problematic.Since this putty material has a high hardness. Fill in groove...

Various alternative sources of electricity are increasingly interested in homeowners. They are attracted by the low cost of using solar energy. But the mass introduction of devices operating from the solar light flux is constrained by the high cost of equipment and the complexity of its selection and installation. In fact, to assemble with your own hands and operate a solar power station is within the power of a home master, even a senior student. To do this, you need to: familiarize yourself with the principles of operation of the circuit, determine the tasks of the equipment, select the most suitable equipment for the station, conduct mechanical installation of all elements, assemble the electrical circuit, verify operability and correctly operate it.

Numerous practical experiments allow us to recommend a universal scheme for solving the problems of a solar power plant for the home.It includes: solar module ...

There is such a profession in the energy sector: to protect people and equipment from short circuits and other malfunctions in the electrical circuit. The work is complex, highly paid, prestigious.

Only persistent, purposeful and competent people master this profession. They are usually called by profession - relay workers. This is explained by the fact that for a very long time the relay-based element base is used in the algorithm of protection and automation circuits, although recently microprocessor devices using computer technologies have begun to appear in large quantities.

Just want to give an example from the life of the substation team with equipment operating under a voltage of 330 kilovolts.How relays cope with their duties can be learned from the sad example of an accident. A repair team led by ...

It seems that there is no such office where Armstrong-type false ceilings are not used. So tightly they entered our life. As there can be no such organization, from a kindergarten to a business center, where 60 x 60 cm ceiling lights with four fluorescent lamps, which are built into a suspended ceiling or laid on, would not be used for lighting.

Such lamps have become such a familiar attribute of the modern average standard design that others are now difficult to imagine. The power of the lamps of such lamps: 4 x 18 W or 4 x 36 W. The cost reaches 5600 rubles. For the nineties, when incandescent lamps were widely used, the new fluorescent lamps were a real breakthrough not only in design, but also in energy saving. However, technological progress did not stand still, and now LED lighting has become an alternative fluorescent tubes...

Electric heating elements are used in household and industrial equipment. The use of various heaters is known to all. These are electric stoves, ovens and ovens, electric coffee makers electric kettles and heaters of various designs.

Electric water heaters, often referred to as boilers, also contain heating elements. The basis of many heating elements is a wire with high electrical resistance. And most often this wire is made of nichrome.

The oldest heating element is perhaps the usual nichrome spiral. Once upon a time, home-made electric stoves, water boilers and goat heaters were in use. Having at hand a nichrome wire that could “get hold of” in production, make a spiral of the required power ...

As often happens, everything turned out quite by accident. A friend asked me to deal with the high power consumption of garden lighting in a country house and its reliability. If necessary, I asked to put a separate voltage regulator for lighting, since the mains voltage is unstable and often low.

About a year ago, an acquaintance already began the struggle for energy savings. He replaced incandescent lamps in garden lights with compact fluorescent energy-saving lamps. The energy savings turned out to be significant when compact fluorescent lamps were installed instead of 21 pieces of conventional 60-100 W lamps. The company did not stint and put "OSRAM" 24 watts. The homeowner arranged a saving result. But over time, the disadvantages of the new lamps became noticeable. For example, a base with electronics for an energy-saving lamp ...
