They say everything old is new again. And energy here, it seems, is no exception. Burned on Chernobyl, faced in some places with the threat of an energy crisis, mankind increasingly turns its gaze on technical solutions, unfairly written off in the past in the archive. The use of the gratuitous forces of the wind among such solutions. Come to them in their creative pursuits and like to make things with their hands (see, for example, “M-K” № 4/84, 5/86, 6/90, 7/92|.
In the process of cleaning leaving cleaner air is not “dispersed” dust the room, suggest to the exit hole, insert curved pipe, directing the stream up. The corresponding diameter of the hole and the tube can be provide with podmahivala tape. A. IVANOV, S. Ivanovka
Before copiers that manufacture aircraft models in the Mel scale, often raises the problem of simulating a power plant with a radial engine. Offers an unusual method based on the use of… conventional steel screws or bolts. First, you need to pick up screws with fine or medium threads, the outside diameter corresponding to the cylinder size of the engine. The screws are trimmed to length and with one edge sharpened needle files tapered tetrahedron (the angle and depends only on the number of cylinders). Then, treating the sharpened surface etched with acid, they oblizyvaet using a soldering iron.
Few people know that packaging Styrofoam is the perfect base for the manufacture of varnishes and paints. The first are obtained by dissolving the foam in solvent “647” or butyl acetate. On the basis of this lacquer you can get a very durable paint Serebrianka, for which the composition is added to aluminum powder. Read more…
Practice starts in the competition boat-“bramahadev” convincing evidence that until today the question of establishing a simple and reliable device for shutdown of main engines after completing the scoring of the race remains open. That is the problem and is dedicated to offer modelers the material.
To unsolder chips from a PCB — troublesome. However, it is simpler if we use a medical needle, a sharp tip which is pre-cut with a needle file or abrasive block. O. I, Voronezh
To accelerate the defrosting household refrigerators are very convenient to use the pan-the pressure cooker “Minute”.

Using this “steam cutter” easily cut through the snow coat on the individual Read more…
Even perfectly executed a valid copy of a military ship or self-propelled artillery loses much if its design does not allow to simulate the use of the main weapon of the prototype. But most known simulators does not provide the sound similarities with a shot or hampered their placement.
Preparation for the winter vegetables, fruits and berries in many cases, connected with great inconvenience due to the imperfections of technology and primitiveness kitchen appliances for the job. I would like to offer home hosts a very simple device that helps to simplify and even to protect their work. Let me remind you a bit of a process.
