That fuse in the radio, will alert you to the simple automatic device, scheme of which was published the magazine “Radio Fernsehen Elektronik” (Germany). While a fuse F1 (see figure), the voltage between the emitter and base of transistor V1 is equal to zero and a semiconductor device is closed. Once the fuse will burn immediately on the basis of V1, a voltage is applied, opening the transistor and the led B1, included in the collector circuit will light, indicating an “accident”.THE INDICATOR OF BURNING OF A FUSE

The country’s economy demands a more versatile, capable of performing several operations simultaneously or transformable vehicles. Very seriously, and most importantly — an inexhaustible invention relate to the creation of advanced machines of its kind in Cute Novosibirsk Akademgorodok. They first wonder how fresh and original ideas in design! And potam admire the elegance and completeness of solution. No wonder the mentors Kutuzov along with making the guys thinking out of the box many time I spend in the formation of their aesthetic taste, sense of harmony.
About 190 km/h! This is a technical medium speed modern racing model with a powerful engine. Moreover, the maximum operating speed of the model exceeds 170 km/h, this is not the limit. Constantly improving miniature aircraft, athletes strive to further reduce the time of passage of a ten-kilometer distance. Before the Modeler, usually three ways: change the layout scheme, forcing the engine and improved aerodynamics models.
The first time I saw this unusual rocket in 2007 in the championship of Russia in Orel. At the start of class models Ѕ4А my attention was drawn to the flight of the rocket glider container type. From the start of the Protocol we learned the name of its designer — Sasha Scoops from the team of the Krasnodar territory and the flight time is maximum (3 minutes). Just wanted to meet the designer, but in the starting area he appeared and after the second round. But the Protocol after the red number “180” was listed a “0”.
In the latest issue of our magazine published a series of articles of the group of designers of the gyros about the features of the construction of these helicopters, how to build gyroplanes, how to fly them, towed by boat or car. In this room we talk about the fuselage structure and the governance of the autogyro (or Meropenem, since they are identical).
