COFFEE? SEEDS? 10 MINUTES!

COFFEE? SEEDS? 10 MINUTES!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.

ANTI-THEFT – IN 5 MINUTES

ANTI-THEFT ALARM FOR 5 MINUTESAfter 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!

NEW TECHNOLOGY

NEW TECHNOLOGYWith 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”.

FLIGHT ELECTROLET

AEROBATIC ELECTROLET

Judging by the letters from our readers, the interest in the model aircraft with electric motor is not reduced. Comes a lot of questions about the challenges of producing interesting flying machines and development of specific projects. One of them we want to acquaint the followers of electroperu. Very effective control line aerobatic model created by A. SUHANOVYM from the city of Astrakhan. In addition, they built “nilotica” interesting minimal use balsa, which gives the possibility of playing in almost any conditions. If necessary, balsa items without much damage to the mass of the model can be replaced made of lightweight Linden (in this case, TopMenu blanks should be reduced in half to two times).

TWO FIGHTING WING

TWO FIGHTING WINGDeveloped in the circle of aircraft modeling station of young technicians of the city of Berezniki of the Perm region and the following proposed model of “air combat” is designed for mid-level athletes. They are distinguished by a good performance, sufficient strength and manufacturability. But for some modelers who do not have experience with foam lomikami or do not have access to the material of the required quality, it may be advantageous to use as the main material lime veneer (which, as a rule, can be made independently). Both bouzouki built on a “flying wing”, dominant in the Junior class and sports the “air battle” of the last decade.

ERSATZ FUEL “CALLOC”

SUBSTITUTE FUEL

Search methanol for glow motors have always been a big problem. The situation is slightly simplified Pope the publication of interesting material about the ersatz fuel in the “M-K” № 6, 1986. However… was not so easy to find and required for its preparation the solvent oil-based paints. Finally the problem was solved after the publication of a number of other recipes fuel mixtures in the “M-K” n b star 1990. Of all the options the most simple mixture based on gasoline And-76 and AI-93. However, there is little difficulty. On a mixture of perfumes work well only with a special selection of glow candles. But this possibility is not at all.

GENTLE TRUNK

GENTLE TRUNK

There are many clamps to secure the roof rack of the car. However, quite comfortable and no unsightly gutters on the roof I did not have to meet. Offer readers the “M-K” I developed the design of the locking mechanism of the trunk. It was developed with the proviso that in the manufacture of trunk with such clamps can only use the locksmith tools.
