The Russo-Japanese war, which began with a sudden attack of the Japanese on Port Arthur on the night of 8/9 February 1904 and virtually ended with the defeat of the king’s fleet in the Tsushima Strait, with merciless clarity showed the backwardness and complete collapse of the Russian autocracy, incompetence and venality of its military elite. But this war showed the world great examples of valor and selflessness of the Russian soldiers, sailors, and the best part of the officers. Shots, sounded in the outer Harbor of Port Arthur, was a prelude to the heroic drama in Chemulpo, where in an unequal battle against the squadron of Admiral Urn die the cruiser “Varyag” and the gunboat “Korean” die with nesuderinami flags, flooded and blown up their teams, who chose death shameful surrender to the enemy.

People sometimes just have no time to twist knobs of the receiver to switch from one frequency to another. Here comes the advance settings of some of the most popular stations, pressed a button and listen to the desired program. In this mode you will be able to work any long-wave radio with a homemade console, designed for several fixed frequencies in the range of SV.
Development and manufacture of printed circuit boards for a single instance of a homemade device with a higher density of mounting becomes sometimes a problem even for the experienced radio Amateur. I have also found the opportunity to do without any preliminary layout of printed wiring conductors, and even without soldering electric and electronic circuits. I replace all of that… wrap.
Anti-aircraft guided missiles (AAGM) is located at the junction of rocket technology, electronics, precision mechanics and chemistry, and are the most complex class of missile weapons. Because of this, none of them in the years of the Second world war were brought to combat use, though the development and testing of such systems was carried out in England, USA, Germany and Japan.
The simplest water supply and Sewerage for country home. To live in the country like human beings, should, in principle, not so much — light, water, a decent toilet and sanitation. With the light problems not too much— even if there is no centralized electrification of the suburban village, you can buy portable gasoline generator and enjoy all the benefits of civilization, which gives electricity.
PROPOSED RC MODEL GLIDER WITH an ENGINE displacement of 2.5 CM3 model airplanes BUILT by the CZECH VLADIMIR BILY, IT MADE ABOUT 370 FLIGHTS (80 HOURS). THE MODEL IS EQUIPPED WITH DVUHKOMNATNAYA EQUIPMENT.
Existing acoustic system (as) furniture type mostly rather cumbersome and expensive. To use them when testing and setting the audio uncomfortable. And in ordinary surroundings while listening to the radio and music are often given preference more simple and accessible to speakers of small capacity, including homemade, produced from scrap materials.
Georgia — the country is amazing, not just amazing, but, unfortunately, unfairly deprived of attention. Tourists in Tbilisi should visit the cable car, which immediately attracts attention, once you get into the city. Tourists often mistakenly call it a funicular. Cabin cable car will take you to one of the most popular viewpoints for a few minutes, and then you can get to the oldest landmarks of the city include the Narikala fortress.
Bomber P2V NEPTUN. In the late 30-ies of the leadership of the U.S. Navy began to develop the requirements for patrol aircraft anti-submarine escort convoys and deep sea exploration. New aircraft with long range flight was to carry the weapon systems of a wide range from conventional bombs to sea mines and torpedoes. To develop for this purpose flying boat did not make sense, because its pressurized fuselage are not satisfied with the capacious bomb Bay and external weapons worsens the already poor aerodynamics of a floatplane, reducing the maximum range and speed of flight.
(The end. Beginning at No. 10, 1973) In the tenth issue of the magazine, readers got acquainted with the General layout of the three-wheeled micro-car, only “Friendship” design Bykovskiy, G. Malinowski and B. Horev. Today we talk about refinement and alterations to the factory components and parts that have been applied in the construction of this interesting machine. Remember that to make their own does not make sense. Even with the appropriate machining equipment it will greatly increase the cost and complicate the work, not to mention the fact that the quality of parts made in primitive conditions, much lower than factory.
