One of the prominent Russian researchers in the field of fundamental physics was Rimilii Fedorovich Avramenko (1932 - 1999). The author of more than 100 scientific papers and more than 40 inventions and patents, Rimiliy Fedorovich was a member of the Russian Academy of Natural Sciences, was engaged in, among other things, research in the field of energy, and set out the results of some of his observations in openly published scientific articles.

In 2000, the book “The Future Opens with a Quantum Key” was published, after the title of the same article by Avramenko on the energy potential of a vacuum, which presented articles, speeches and notes of the scientist and his colleagues. After performing many experiments and carefully examining the scientific material accumulated by physics, the authors of the book answered the question “what makes up the bulk of the mass of the observable Universe?” The answer was this: the world is filled not only with “warm” relic photons, but also with “ultracold” electrons ...

RFID (Radio Frequency Identification) is a way to ensure the storage and transmission of information from a convenient label carrier to the desired location using special devices. Such identifier tags make it easier to recognize various objects: goods in the store, mobile vehicles during transportation, help determine their location, can identify people and animals, not to mention the wide possibilities of identifying documents and property.

The electromagnetic wave received by the RFID tag from the antenna activates it, and it becomes possible both to write data to the tag and to read data from the tag. The antenna thus serves as a multifunctional communication channel between the transceiver and the tag, which fully ensures the processes of data transmission and reception. Antennas of various shapes and sizes can be built into scanners, gates, turnstiles, - in different means for working with RFID ...

An installation box for a hidden installation, designed to mount an outlet in it, is called a socket box. Most often, the undergrowth has a round shape (less often square) and a standard size. The main function of the socket is to provide a rigid and reliable mounting place for the outlet inside the wall, near the plane of its surface.

If you needed to install a socket, then armed with quite ordinary tools (pencil, level, putty knife, brush, hammer, chisel, drill with a crown, alabaster), you can do it yourself. Observe safety precautions, first turn off the power supply in the shield, carefully use the tool, remember the standards - and everything will work out. First, markup is made relative to the wire going to the future outlet. Draw a horizontal line at a small distance from the wire - this is the level of the center of the future outlet ...

To determine the current value in an electric circuit, special devices are used - ammeters. The ammeter is connected in series to the circuit under study, and, due to the extremely small intrinsic resistance, this measuring device does not make any significant changes to the electrical parameters of the circuit.

The instrument scale is graduated in amperes, kiloamperes, milliamperes, or microamperes. To extend the measurement range, the ammeter can be connected to the circuit through a transformer or parallel to the shunt, when only a small fraction of the measured current passes through the device, and the main current of the circuit flows through the shunt.Today, there are two particularly popular types of ammeters - mechanical ammeters - magnetoelectric and electrodynamic, and electronic - linear and transformer. In a classic magnetoelectric ammeter with an arrow ...

Not every housewife will immediately figure out how to convert amperes to watts or kilowatts, or vice versa - watts and kilowatts to amperes. Why might this be required? For example, the following numbers are indicated on the socket or on the plug: “220V 6A” - marking reflecting the maximum permissible power of the connected load. What does it mean? What is the maximum power the network device can be plugged into such an outlet or used with this plug?

To get the power value, it’s enough to multiply these two numbers: 220 * 6 = 1320 watts - the maximum power for a given plug or socket. Say, an iron with steam can be used only on a deuce, and an oil heater - only at half the power. So, to get watts, you need to multiply the specified amperes by volts: P = I * U - multiply the current by voltage (in the outlet we have about 220-230 volts). This is the main formula for finding power in single-phase electrical circuits ...

When the light goes out in a house or apartment, not only does the connection with civilization disappear, but the products in the refrigerator begin to deteriorate, especially in the summer, especially in the southern regions. Someone did not have a gas, but an electric stove, not to mention a computer, TV, electric kettle, etc. This was fully felt by those who lived in the 90s. On the territory of Russia and the CIS during that difficult period, here and there, there were regular interruptions in electricity, and it was not uncommon that entire city blocks were saved in the evenings only with wax candles.

And although the dashing 90s are behind, in some places even today there are sometimes interruptions in power supply. This problem, of course, is solved by the use of modern uninterruptible power supplies (UPS) or liquid fuel generators. But not every homeowner can afford a high-quality autonomous power supply for an apartment, not to mention a large private house. Let's look at the possibilities for offline ...

In this short review, we consider four types of relays controlled via the Internet from the Russian company KERNELCHIP. For over 10 years, this company has been professionally developing and programming non-standard devices for interfacing with computers, as well as developing automation and control systems and remote control and monitoring systems via Ethernet and GSM / GPRS. Today, when the Internet is everywhere, such solutions are more relevant than ever. It will be about the controlled relays of the Laurent series.

The Laurent-T module has a feature - a special purpose: the collection and transmission, via Ethernet (LAN) interface, of the readings of digital temperature sensors. The module is capable of working maximum - with 20 sensors of the Dallas DS18B20 type. Sensors are connected to a 1-Wire common bus. So Laurent-T is an Ethernet temperature controller ...

In October 1975, California inventor Robert Alexander introduced the public to an advanced drive for a car. According to the inventor, this electric drive was supposed to save car owners from the need to use combustible fuel, from excess noise, and from the need to constantly recharge the batteries.

The experts who arrived at the demonstration were very puzzled, because it seemed that the energy comes from "nothing." However, the car drove easily without fuel at a speed of 36 miles per hour. To experts' doubts, the inventor replied that the car was driving, and she did not care about their arguments.The initial power was provided by a converted electric motor of 7/8 horsepower. The electric motor was redone so that 12 volts were obtained at its output, otherwise the output power would be too large ...
