Multi-purpose fighter F-5E. After the Second world war, the US claimed, not without reason, on the role of world leader, particularly in aviation. The leadership was obliged to provide economic and military assistance to allies.
THE PUMP UNDER CONTROL
Motorists have appreciated a commercially available foot-pump to inflate tyres equipped with pressure gauge: it is easy to use and allows you to constantly monitor the pressure in the chamber. But the pump is the old type with the help of simple consoles can be equipped with a pressure gauge. This would require a metal Read more…
This kind of furniture can be included at equipment a large kitchen, often used as a dining room or stand in the living room, especially if there is a dedicated functional area. Bedside table-bar offered by the Hungarian magazine “Earmaster” successfully combines beautiful appearance, large capacity and ease of use of its content.
CHARGING AND RECOVERY DEVICE’S BATTERY. The battery in the car is one of the most important elements. Despite the constant efforts of manufacturers to improve the reliability and durability of the batteries after 3 — 4 years they still come into disrepair, aided by a constant undercharge when riding in urban environments the cost of the battery remains high, so to extend the term of its service makes sense at least once in the summer season to carry out remedial exercises.
A small group of enthusiastic scientists and engineers of the Department of theoretical mechanics of the Kursk Polytechnic Institute, working on the creation of an engine operating without fuel and electricity: they are… replace the flywheel. About these interesting looking we asked to speak to the group leader, doctor of technical Sciences, Professor Nurbay Vladimirovich Gulia, head of the Department of theoretical mechanics Institute.
Training RC model airplane. This publication is for those who have sufficiently mastered the piloting cord model airplanes and thinking about the next step — creating the RC. You can, of course, buy ready-made miniature replica of the aircraft and start its development, however, great pleasure from it is unlikely to get made with your own hands and independently adjusted and test flown the model is not interesting example. And cost is cheaper to buy will have only the remote control equipment Yes servos.
Nowadays, the drill is not uncommon. Drill a hole in the concrete wall or polished metal part having a cartridge holder with a felt circle — in such cases it is indispensable. Wooden disk glued with a cloth will help you Polish any flat item, and if between the skin and the drive to lay the foam, you can tear off the old varnish from the floor, grind the surface of complex shape.
Czechoslovakia justly called the center of Europe: at its plants at different times was created by the machines and equipment are well known throughout the world and is characterized by high reliability and original design solutions.
Karting is the most popular and accessible to young people kind of motor sport. It is also interesting that card — an object of technical creativity.

The simplicity and low cost of raw materials enable schools, Palaces of pioneers and the young technicians ‘ stations to build as many carts as you need for simultaneous teaching of a large group of guys. Also important is the advantage that these sports cars are cheap to operate and do not require storage spacious garages.
Usually automatic device switch on and off the Christmas tree lights in leaps and bounds, without changing the brightness. But the electronic switch scheme is presented in figure — does not have this drawback. The basis of his work is based on the principle of beats that occur between the frequencies of the mains and generator. The latter is a multivibrator transistors T1, T2. It generates rectangular pulses with a frequency of (100 ± Δ) Hz (100 Hz is the fundamental frequency of the multivibrator, And the frequency of the beating, which switch lamp garland which is in the range of 0.1—8 Hz). Adjustment of the burning time of the lamps is variable resistor R6 “Smoothly” and R7 “Rough”.
