In Amateur practice when developing or building a device often require multiple power sources at different voltages. For example, structures made in operational amplifiers and working in conjunction with digital integrated circuits require the bipolar and unipolar current sources. To use in such cases, the voltage divider is uncomfortable, especially in the process of developing new devices. After all, it is necessary to change the number of elements used and their type, which leads to a change of energy parameters of the device, and hence to necessity of the divider.

Cooking, usually accompanied by a aerosol air pollution in the kitchen and throughout the apartment. In this form fat particles, soot, soot, etc., which are deposited on the ceiling, walls, Wallpaper, furniture, curtains. It is also possible the formation of harmful products of incomplete combustion of gas and unpleasant smell of burnt food.
Many years used the intercom system with loud-speaking simplex communication, consisting of a main panel and linear unit connected between a two-wire line. The radio was mounted low frequency amplifier. Here was the power source.
The windsurfer, like any sailboat needs wind. Meanwhile his body-the float if necessary, you can swim in the calm. In the journal “modelist-Konstruktor” once mentioned about using the body in the rowing version, with two-bladed paddle or with a conventional pair of oars (though in the latter case, had to build a removable frame with a seat and two supports under the oarlocks).
Today, Bentley is part of Volkswagen group. That is why many units of the new two-door BENTLEY CONTINENTAL GT coupe borrowed from the AUDI A8 and VW PHAETON. In particular the machine is equipped with volkswagenwerk motor W12. The length of such an engine is comparable to row “four”, so the designers managed to place it in the base behind the front axle. It brought the CONTINENTAL GT by weight distribution by Central motor performance.
Any motorist knows that the state of charge of the battery must constantly monitor is required to control the pressure on it. This can be done by using electronic circuit which gives an alarm when low electrolyte level, high overload, contamination of the terminals of the battery, breakage of the drive belt of the generator, the overcharge of the battery.
A crushing defeat of Japan in 1945 radically changed the geopolitical situation in the far East, however, does not make this part of the globe calm. A series of bloody wars in China, Indochina and Korea led to the split of Nations and the emergence of new tensions. All this occurred against the background of confrontation between the two superpowers — the USSR and the USA trying to engage the warring regimes in its orbit. So in the camp of the allies of Washington and its former enemy Japan, and longtime enemies of the past — South Korea and Taiwan.
The design of this portable barbecue grill is convenient to use in field conditions (e.g., hikers, hunters or fishermen), and in the garden area or in the country for quick cooking kebabs or roasting vegetables, toasting frankfurters, sausages, fish.
Fishing hook is such a classic that no one can tell when he appeared. Since time immemorial, the shape of the hook remains unchanged. Come up with a new hook is to offer a new bolt, nut, wheel. Probably no one is trying to invent on the subject.
Offer simple design of gliders developed in the circle of experimental design. syut Kostroma. They are all made mostly of foam, but differ from each other in size, proportions, mass, manufacturing technology wing flight characteristics. Models are recommended for the manufacture of young modelers in the home, in group classes and the technology classes.
