Homemade welding machines are engaged not the first year. In their manufacture into account the advice and recommendations of the “Model construction” and other well-established technical publications and reference literature. Started with “Welding baby” (No. 11, ’87), using the Latr ready with the primary winding. For secondary — recommended magazine, Shino-wire not found. Dare to wind the desired number of turns of the flexible stranded wire 6 mm2 in vinyl insulation. And what? Of course, such a device quickly overheated even when welding of cellular electrode. To somehow solve the problem associated with cooling, have decided to omit the “svarochnik”… in the water. Came from the fact that the secondary winding is great for insulation. And primary, which went before the slider wasn’t exposed as proactively managed to cover it in several layers of protective varnish.
FILTERED ANY WATER
Most water filters designed for connection to the tap water. And what about those who have “bucket-wire”, who carry water from a well? In these times and so often you have to clean. It is for this purpose I had to fit the filter “spring”. The tip that fits over on the faucet, I took Read more…
Many quite rightly believe that automobilism is one of the most exciting and spectacular forms of diverse technical activities. Here you can find a lot of sharply differing from other classes of models, including, it seems, the whole conceivable spectrum of interests of athletes and fans of all ages.

In the same year took place in Tambov and the first “booster”, the championship of Russia in the new class. Participated athletes using exclusively machine-handmade. Unfortunately, the result of these competitions was due to poor weather conditions is almost zero.
In October 1996 in the Udmurt Republic celebrated the 65th anniversary of the system of children’s technical creativity. In 1931 in Izhevsk was opened the first children’s technical station, later received the status of Republican. Over the years many students RSUT became heroes of the Soviet Union, doctor of technical Sciences, honored workers of science and culture, managers of industrial enterprises, masters of sports. Best work 236 young technicians Udmurt Republic were awarded medals VDNH USSR, many leaders awarded gold and silver medals, received the title of laureates of the NTTM, 42 pupil participated in the international exhibitions in Japan, France, Germany, Belgium and other countries.
In our area, where most of the year is negative or close to zero temperature, it is foolish not taken advantage of the free cold storage of vegetables, fruit, roots. It would be nice. for example that the houses were built with the corresponding chambers in the walls of the kitchen, where he was would be Santa Claus. But somehow, the architects of this not yet provide. However, the situation can be corrected by yourself. I have made and for several years successfully operated kitchen wall Cabinet-column for storing potatoes. Through the intake tube, it enters from the street the cold air. Overlapping holes if necessary, you can adjust the temperature in the column.
