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.

This event happened April 12, 1961: a powerful carrier rocket put into orbit a spacecraft “Vostok”, piloted by our compatriot Yuri Gagarin. His name was the synonym for extraordinary heroism and amazing courage. The loud echo of the flight immediately and reached the “shores” of the world of philately. Post offices 25 countries dedicated to Yuri Gagarin about 150 commemorative stamps and blocks.
The new law on compulsory insurance of vehicles in conjunction with the ever increasing prices of gasoline has forced me to give up reliable motorized assistance scooter cargo “the Ant-2M”. I sold it in good hands — in the village.
Designers Uralvagonzavod im. Dzerzhinsky, overcoming many difficulties, has created an entirely new fighting machine of the it-1 was the first domestic tank with high-precision weapons. The tank destroyer was a closed military tracked machine, having a powerful missile weapons, reliable armor protection and high mobility, designed to destroy enemy tanks and other moving and stationary armored targets potential enemy at ranges up to 3 km.
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.

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.
