As the main or additional source of heat in modern homes and apartments often use an electric heated floor. Often - as an extra, and there is an opportunity to choose. It can be a continuous floor covering, or just a warm piece of a small area in the hallway. For small areas, for example, an ultra-thin heating cable is very convenient, and for large areas a single-core or two-core heating cable (it can go in the form of a mat or on a coil) is better.

The heating cable is mounted under a cement screed, the thickness of which depends on the type of cable. It is best to carry out installation even at the construction stage, or in extreme cases - during the overhaul process. If repair is not expected, then it is possible to install a warm floor from an ultra-thin cable, which is laid without thermal insulation in a layer of tile adhesive ...

In this article, I will tell and even show clearly, in pictures, how to transfer the generator to gas. Can I make a gas reducer myself? In many forums, on the Internet, on youtube you will find a bunch of recommendations on how to convert a gas generator to gas. Someone recommends using home-made gearboxes, which I categorically do not recommend doing, there are also ready-made gas kits that allow you to remake the “native” carburetor just for working on gas, while others drill something in the carburetor ...

All this, let’s say, is not the best and safest way to convert a gas generator to gas. Why reinvent the wheel and seek adventure at its fifth point, when everything has already been invented and tested on hundreds of generators. I recommend to purchase such a gas module. How much is a gas kit? The issue price is only $ 50-60. Agree, the money is relatively small. For the money you get a new carburetor ...

Everyone who watched the Back to the Future trilogy probably remembers how Marty McFly escaped the chase on a hoverboard soaring. To this day, the idea of ​​recreating a hoverboard excites the minds of many inventors - enthusiasts. Even Lexus did not neglect this idea. However, not only Lexus achieved their goal on the way of translating this fantastic vehicle into reality, but first things first.

At the end of 2014, after successfully collecting $ 500,000 on kickstarter, Greg and Jill Hendersons realized their plan. By creating Arx Pax, the couple finally built the world's first hoverboard, which they named Hendo Hover. The skateboard hover technology is based on the repulsion of magnetic fields, which creates a counteraction to the force of gravity. The magnetic cushion trains soar in about the same way, the only difference is ...

The safety of using electric energy depends not only on the correct installation of the electrical installation, but also on compliance with the requirements laid down in the regulatory documentation for its operation. The grounding circuit of a building, as part of protective electrical equipment, requires periodic monitoring of its technical condition. In the normal power supply mode, the ground loop of the PE conductor is connected to the housings of all electrical appliances, the potential equalization system of the building and is inactive: through it, roughly speaking, no currents pass, except for small background ones.

In the event of an emergency related to the breakdown of the insulation layer of the wiring, hazardous voltage appears on the body of the faulty appliance and flows through the PE conductor through the ground loop to the ground potential. Due to this, the value of the high voltage transmitted to the non-conductive parts should decrease ...

In 2004, Russian scientists Konstantin Novoselov and Andrei Geim working at the University of Manchester (Manchester, UK) were able to obtain graphene on a silicon oxide substrate.It was a stable two-dimensional film due to its bonding with a thin layer of oxide (dielectric). The parameters of carbon films one atom thick (a million times thinner than a sheet of paper), such as electrical conductivity, the Shubnikov-de Haas effect, and the Hall effect were then measured by scientists. Novoselov and Game received the Nobel Prize for these advanced works in 2010.

Today graphene can rightfully be called revolutionary material of the 21st century. This carbon compound is the thinnest, strongest and has the highest electrical conductivity. Today, several billion dollars has been allocated for the study of graphene, and according to scientists, this material can replace silicon ...

Gate means a mechanical structure mounted in a wall to restrict and regulate access to a controlled area. According to the device, they can be conditionally divided into: a mechanical enclosure attached to the building elements of a building or fence as part of a stationary and movable structure, a drive that performs the operation of opening or closing the gate leaves with a fixation of the executed position, automation that controls the operation of the main parts of the drive system.

According to their technical performance, modern designs used for installation in a cottage, cottage, garage are mounted according to one of the following principles: hinged, usually made by two leaves, sliding, made by a single solid door moving along the lower metal tee or other supporting profile and supported by top rail ...

The video course was released by the company Aries. The author is Kirill Gainutdinov. The course allows you to learn how to easily work with the Aries PLC110 controller. Video instructions provide clear recommendations on the most common issues.

For example, for beginners it is: how to start working with a controller, how to create your first project, etc. Advanced users will also find answers or important tips for themselves, for example: how to connect external devices to the PLC110 ARIES controller - such as input-output modules, panel controllers, frequency converters. In addition, the course includes a video on setting up work with wireless networks and archiving. PLC is a programmable logic controller. The programmable logic controller Aries PLK110 is designed to create automated control systems technological equipment in various fields...

Portable generators can be used almost anywhere you need electricity. Tourists use them to light tvs for food, enjoying the fresh air. Builders use generators to power power tools at construction sites not yet connected to the city’s power grid. In private homes and enterprises, generators are used as part of the power system, which allows you to continue to use various electrical appliances for the duration of a power outage in the main network.

But, regardless of their purpose, generator engines require fuel. Most portable generators run on gas or gas. Both types of fuel have their advantages and disadvantages, and we’ll talk about this. Gasoline generators are the most common type of generator, because gasoline, unlike gas ...
