FLYING “SAUCERS”

FLYING Victor E. Marina from Rostov-on-don from a young age engaged in the construction of models of free flight. In recent time, leading a circle of aircraft modeling on obsut, he became interested in the structures with circular drainer, discreto. However, to achieve good results for a long time could not — flying “plates” were heavy, clumsy, and most annoying, bad flying.

B-25 “Mitchell”

B-25 During the great Patriotic war in the Soviet Union from the United States and supplied under lend-lease twin-engine bombers b-25 “Mitchell” company “North American”. The aircraft started to be developed in 1938 as an attack-bomber. He had dvuhkilevoe tail and tricycle landing gear support to facilitate its operation. After reworking the project into a bomber the machine, adopting, received the designation b-25. Her first flight took place on 19 August 1940

CONTACTLESS CAPACITIVE RELAY

A CONTACTLESS CAPACITIVE RELAYThe basis of a capacitive relay — a low-power generator of high frequency such as local oscillator of a radio receiver. To the circuit L1C4 (see diagram) of the connected metal plate sensor. Approached to him the palm of the hand represents the second plate of the capacitor CD. The capacity of such a condenser is the greater, the more area it covers and the smaller the distance between them.

NTTM-2014

NTTM-201424 – 27 June 2014 in pavilion No. 69 all-Russian exhibition centre will host the XIV all-Russian exhibition of scientific and technical creativity of youth NTTM-2014. The exhibition organizers are: the Ministry of education and science of the Russian Federation, Government of Moscow, all-Russian exhibition centre, the Council of rectors of Moscow and Moscow region with the support of the chamber of Commerce and industry of the Russian Federation. Given the importance of the exhibition NTTM in the formation of a new generation of engineering and technical personnel, integration of fundamental science, educational process and production, increase of innovative activity of youth of the XIV all-Russian exhibition of scientific and technical creativity of youth included in the Plan of participation of Ministry of education and science in Russian and international events in science, technology and innovation in the framework of the Year of science Russia – EU 2014.

STENCIL

STENCILDraw the circuit diagram, weathering adopted the proportionality of graphic symbols electronic elements, it is not as simple as it might seem at first. Great help here can have a stencil plate of thin transparent material with holes and slots corresponding in form to symbols of parts adopted in the Unified system for design documentation (ESKD). This stencil need not only for Amateurs but also professionals working in this field of technology.

DUST AND DIRT

Before painting the ceiling during the repair of the apartment it is usually carefully cleaned of previous coatings, and all around, usually covered that off. To avoid unnecessary dirt succeed, if work brushed metal with a rubber trim around the edges and a hole in the middle for connection with a pipe cleaner.

ARMORED “BULAT”

ARMORED The family of KAMAZ trucks filled up by the new special armored SBA-60-K2 “Bulat”. This war machine was created with the use of units, assemblies and series parts, KAMAZ-5350, commonly known as “Mustang”, which as a military truck was called to military service in 2002, the Mustang has a capacity of 6 tons, a curb weight of 15.4 tons; its 260-horsepower diesel engine allows to reach the speed of 100 km/h. It is a three-axis front-engined car with permanent all-wheel drive (6×6) driven front wheels and two closely spaced rear axles. Carrier system – spar frame. Designed and manufactured by the Kama automobile plant.

FIVE INSTRUMENTS IN ONE

FIVE INSTRUMENTS IN ONEPerhaps the most difficult stage in the process of creating radiokonstruktor — setting. But if you have even the simplest instrumentation, to establish any electronic device will be much easier. At least, for this job you need avometr, or simply tester. For example, very popular among ham radio uses a simple inexpensive device C-20. But the problem is, he is not entirely comfortable, and this tester is limited. So for those of you who already have such avometr, we propose to improve it by extending the limits of measurement and adding the generator probe with the test transistors.
