To complete the profile of woodcarving, offer readers a “M-K” to assemble a simple machine based on the electric drill IE-1036Э with electronic regulator of frequency of rotation of the spindle. This mechanical almost universal, it is suitable for cutting curly proraso as wood and metal. To make it simple saadeldin, with experience on machine tools drilling, turning and milling. To jigsaws will need a pair of gears (Z1=14 and Z2=40), bolts, bearings, pipe pieces, a piece of steel channel, steel plates of various sizes.

Anyone interested in the history of armored vehicles is well known that highly characteristic feature of the external appearance of the German tanks since 1943 was an anti-magnetic coating of armor — so-called “zimmerit”. Originally this coating was intended only for the Eastern front, but soon became an integral part of all tanks of the Wehrmacht. “Zimmerit” with a rather complex chemical composition, in simplified form, is represented as a mixture of latex with cement. The idea of such a coating is rather controversial, since the magnetic mines were used only by guerrillas, and after application the tank was still “clean” place (rollers, tracks, etc.). In the end mine was “to stick” and to railway platform, and downhill equally flew echelon with tanks, as with the “Cimmeria”, and without it. But nevertheless, the Germans did it quite costly.
For those who like roasted seeds or coffee beans at home, but do not want to waste time to stand at the stove with the continuous turning of the upcoming Goodies, I recommend a simple and reliable technical solution. Its implementation will require microelectronical, a double reduction from some broken mechanical toys, self-made metal tray is a sieve and a couple of strands of steel wire. And yet, ten minutes of patience to put it in a workable structure, as shown in the figure.
After reading No. 1 “M-K” for the year 1989 description electronic switch-off “weight” of the car, decided to use it as a simple anti-theft tool. However, the replacement of toggle on the button (as advised by the project author V. Arapov) or reed switch occurs very undesirable moment when the voltage produced by the generator will be equal to the battery voltage, the transistor closes. And in the future on-Board vehicle network will be powered by only one generator. And as for fuel economy the engine is regulated to the minimum idling speed, the voltage generated by the generator in this mode, will be low. Therefore, at the moment of starting off (as in a “weak” generator, and when the light is turned on) the engine may stall. But the main danger occurs when emergency braking, as when the engine stops, the on-Board system is de-energized and the brake lights do not burn!
With all the advantages of fiberglass hulls for model rockets the traditional process of production is highly labor-intensive and unsound. Meanwhile, the conversion gave the modelers a new and very interesting material is heat resistant fiberglass gasket STP-4. It is used widely and, having a small official shelf life, often charged and often goes to the shops “Junior technician” or “Do it yourself”.
