INSTEAD OF THE PCB?

INSTEAD OF THE PCB?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.

THE LAST FIGHT “TERRIBLE”

THE LAST BATTLE 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.

ANTI-AIRCRAFT MISSILE “RHEINTOCHTER”

ANTI-AIRCRAFT MISSILE 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.

PATROL WITH NUCLEAR WEAPONS

PATROL WITH NUCLEAR WEAPONSBomber 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.

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.

THE LAST “AMX” FRENCH TANK OF THE DYNASTY

LAST Tank builders from different countries have sought to create a new machine jointly. In the summer of 1963, the Ministers of defense of the United States and Germany signed an agreement on joint development of main battle tank for the armies of both States on the program of the MBT (Main Battle Tank). In 1969 tests were presented prototypes of tanks, MBT-70, developed in Detroit, and in Augsburg. Although the sample was designed according to General technical requirements, they differed significantly from each other with weapons, engines, chassis. As a result, in the same year, the Alliance broke up, dispersed and tank builders, who then went their separate ways. In the US there was a tank “Abrams” in Germany – “the Leopard”: similar in their main characteristics, but at the same time.
