In this competition almost everything was as really big car races: clearly marked and numbered paths, a huge inscription “Start” and “Finish” bright lights, signal lights, gambling, overlapping the voice of the broadcaster the cheers of the fans, overtaking each other swift cars. Still, the racing was unusual. They were not on the racetrack, and in the great hall of one of Omsk schools, and even the largest of launched cars easily fit in the glove box of the usual “Zaporozhets”. As for the racers, most of them have not had time to get out of the pioneer age, and some even from October.PIONEER RACING

The modelers are well aware, how difficult it is to make a model submarine. A lot of time is spent on installation and electronic equipment, debugging it, setting up steering mechanisms, so that the boat promptly sank and floated. And a disappointment for the team and shipbuilder, when she for some reason goes under the water and no longer appears. Then it is looking for divers and even divers. And not always successfully.
In the sixth issue of our magazine in 1974 we told about the device “Pulse” for the control of knowledge of students. Practice operating the machine created by the participants NTTM Donetsk Polytechnic Institute, as well as the feedback from readers has convinced authors of the need to improve the design.
Graceful and swift motorboat is an excellent educational model for aspiring shipbuilders. Work on bliss allows you to develop basic skills that will be required in the manufacture of sports cars of high class. With these boats, if they do, you can arrange competitions; it is only necessary to equip them with outboard electromotorically and to provide a place for mounting a battery from a pocket lantern.
In the last issue we talked about last representatives of cruisers with over 20 years of ex-one of the most important and revered ships in the fleets of all the major Maritime powers. The class that developed it seems to be quite natural and successful, but which is completely and permanently disappeared from the plans of shipbuilders in just two to three years.
10 years — 15 ago, the industry was widely released table lamps with fluorescent lamps, designed for a voltage of 127 V. A today 127 V network was preserved only in rare homes. It is clear that the owners of these lamps was now “tied” to expensive and bulky step-down transformers. We offer our readers we developed and tested a device that allows you to include a 127-volt lamp in the network a voltage of 220 V without the step-down transformer.
Futurologists from the technique, predicting the future of ground mass transport, a clear preference is given to the development of electric vehicles. However, until now, despite the efforts of scientists of several countries have not yet created a cheap, economical and quite powerful electrochemical generators. Modern lead acid batteries after more than a century of development almost completely exhausted its possibilities.
