The profession of pilot, astronaut, test flight of space technology require absolute health and exceptional emotional stability. To determine the degree of emotional stability of each person with the help of an instrument called emocionalnom. Such a device is designed and manufactured in the Club for young technicians Novosibirsk Akademgorodok.
You’ve probably heard: “he’s Got good reflexes.” Thicket just as they say about athletes. For example, the goalkeeper. He must react instantly to the ball rapidly flying into the net. Or runner, the reaction of which the starting pistol is calculated for fractional seconds. The ability to find the right solution in any sudden situation, it is important for the pilot, the driver, the driver of the tram or trolleybus.
Instruments based on the radio. Determination of the frequency of an unmodulated source, an external signal. With the help of measuring GS you can configure any radio transmitting and radio-emitting devices in the frequency range 150 — 12 000 kHz, in the CW mode, and the mode AM or IM. In the absence of signal modulation of an external RF source (CW mode), its frequency can be determined by the method of zero beating with the frequency of HS. The block diagram implementation of the method of zero beat is illustrated.
When employees of Institute of petrochemical and gas industry named. Gubkin turned in a circle electronic automation of the Moscow Palace of pioneers with a request to produce thermostats for chemical experiments, it is to no one’s surprise. Is not the first creative activities of the children’s team, led by F. Y. Yerokhin, goes jobs scientific institutions and industrial enterprises of Moscow. So this time they decided posed a technical challenge.
To consider, compare, think, manage that work, which are handled by modern computers. With the help of electronic machines is calculated the orbit of the motion of planets, satellites and missiles, the calculated flight speed of elementary particles in nuclear reactors, control machines, production lines, shops and factories. The management of real objects with a computer basically boils down to converting discrete data into a continuous signal. This work is done by auto binary code converters — descramblers. The layout of one of these converters built in school No. 511 of Leningrad. Schematic diagram of the layout in the figure.

Instruments based on the radio. Modification of the receiver “VEF-Spidola”
More precisely, one (50 or 65 watts), operating in three modes. Design advantages: constant availability, visual inspection of the three modes, etc. All provide automation. Power consumption in the idle — 15 watts (on L2), in the normal operating — 45 W (L2 and L3), and overheating — 50 W (L3). Changing modes 2 and 3 is made by the switch B1, in standby mode, by overlapping the luminous flux from L1 to K3 with the handle of the soldering iron.

Instruments based on the radio. Assembly and adjustment of the measuring complex
(The end. The beginning in № 4, 1976) the design quality of stereoleto, the description of which we offer readers, the outer shell of the ear cups made of artificial leather of black color. They are made on a wooden model-the matrix (Fig. 1). The hole is carefully cut out with a jigsaw, and the cut portion is used as a punch. Faux leather cut out a rectangle the size 180X160 mm, remove the knitted lining and evenly stretch the skin on the model, fixing the lower side of the stationery buttons. Then the product is heated to 70— 90°, push in and a punch in the matrix, stand in this condition until cool. Then punch with the buttons removed and the shell removed. On retinectomy frame (Fig. 2, POS. 2) glue 88H glued the foam and cut it in the shape of the ear pads. Thereafter, the sheath is stretched over the foam and glued to the bottom of the frame with glue BF-2, first external perimeter and then the inside. Decorative grille — from pocket radios. Glue it to the frame last.
