Change arrow indicators the dog often come led. And this is not surprising: the second is much easier and safer first. Simple five-level scheme of the AF voltmeter to the voltage of 0.1—0.6 volts, where the indicators are LEDs, published in the journal “Рипката1ег” (GDR). If the signal fed into socket x2, XS, the voltage exceeds 0.1 V, open transistors V2, V4 and, as a result, the led turns on Q1. With an increase of the signal to 0.2 In open semiconductor triode V6 and the led flashes B2. When the signal voltage reaches about 0.6 V, burn all the LEDs.

The kid from the first start push-rod started the engine, and early test-in. The engine revs, causing the car faster and faster to run on the track. Here are the included machine-cut timing a run of eight laps of the race, which is determined by the speed of the model. One lap to another… But it is! The impression is that someone hung on the rear wheels of the machine and slows down her run. Smooth, easy sound debugged in training “engine” was replaced by strained, jagged roar. Of course, the speed shown “shell” is too small.
Trucks fourth generation of GAZ-3307 GAZ — 3309. Automakers used to call generations of a group of machines based on the single structural elements (frame, cabin, engine). And speaking of cars trucks medium-duty Gorky automobile plant, then its currently the trucks GAZ-3307, GAZ-3309 or GAZ-3308 “Sadko” should be attributed to the cars of the fourth generation.
In his hands standing on the bridge of a schoolboy elegant model powerboats. The boy winked one eye, as if before the shot. Finally, the wind has abated a little — it is possible to produce a model. Raising astern low backwash water, the boat went to the goal. After fifty meters posed a number of buoys, medium form the gate width of two meters. It is best to get it in them — a rating in the highest. With a frozen heart, waiting for the young athlete how to behave microcode. There is a hit! Even the rising wind and waves did not prevent him to enter into the Central gate.
Do I have to mug for the second year, two seventh graders. Like everyone else, they began with rezinomotornaya contour of the car. In fact, the tenacity with which even unskilled hands, they grind parts, with some passion launched his first microwaveability, it became clear — will of the good guys. Soon they built from kits and simple racing models with internal combustion engines. Gradually became their skillful hands, the children learned to treat different materials, began to feel that is not enough running mikromotorchika and how to troubleshoot to race “whiz” down the left the entire distance along the path of the track.
“Shortly before the New year left to drink” — whether in jest, whether seriously says on the website www.snowmobile.ru acting under the nickname (alias) Canosa Alexander Zaozerskaya from the city of Totma in the Vologda region. During a multi-day holidays came across the magazine “modelist-Konstruktor” No. 11 for 1991. It was the publication of a homemade crawler snowmobile “Idea-2”. Also decided to try to build a “snezhik”, good experience of working with iron were for his workshop all woodworking machines made with their own hands.
There is an expression: “the Best is the enemy of good.” It remains true, however not always. Any Modeler familiar with one of the standard domestic compression motors — KMD-2,5. Although it is designed for racing model aircraft, it is successfully used and air “fighters”, only pilots and beginners.
