About ten years ago I read in “M-To” article that described the design of the spear gun. Decided using the same principle — a spring as a battery, to make the gun more simple, easy, and good combat. Numerous experiments and fine-tuning have produced the desired result.FROM THE CLOUD — IN FAUCET
Almost every rural or suburban home on the corner, under the gutters is a barrel for collecting rainwater. This, of course, the easiest option, but if m only! Remember: around this place is always damp or even dirty, and the rain falling jet of water squirts all around, harming a examples walls of the house. Read more…
The age of the members in the club of young technicians “planet” in the city of Izhevsk with a range from primary school students to graduates. And if the seniors are more interested in serious equipment (tillers, snowmobiles, ATVs, etc.), for the younger most attractive lightweight motorcycles, it was possible to start to ride. Therefore, the technical creativity of each new generation of young inventors usually begins with the development of mini-mokik. One of these machines has been described in the publication “Gasoline is not necessary” at No. 9 in 1997, “Model construction”. In it they talked about the design on the base frame and running gear from the Riga mini-mokik with motor drive MD-1 serial excitation. Unfortunately, this idea has not received development, as it was not possible to find a more lightweight, but powerful battery is a heavy car, which had to use in this design. Therefore, in the future to drive mokikov used traditional petrol engines type D-6, D-8.
No, we are not talking about shifting residential home from one place to another, what we have witnessed in the period of reconstruction of our cities, and about unusual homes-travelers — cars. It is very difficult to tell who was a pioneer of this new technical direction and on the roads what country had the first car in the back which placed the whole apartment. Most likely, the house on wheels was created simultaneously in many countries, by many designers, and each solved the problem differently- depending on their tastes and possibilities either from the profile of the automotive company where he worked. Under this originated and the principal directions is clearly determined to date, which can be classified roughly as follows.
UNIVERSAL TROLLEY FOR TOURISTS-WATER-TRANSPORT WORKERS. Over the years Hobbies boating, we tested several variants of trucks for transportation of kayak and equipment. And the hikes have seen many different portable transport devices. But they all had drawbacks of a constructive nature that prevented equally well use them for short hikes on weekends and on roads and trails difficult trails.
In the “M-K” appear frequently describe designs that use integrated circuits. The production of these modern elements are so expanded that their widespread introduction in household equipment and in the development of ham radio now is no surprise. However, there still exists an opinion that “communication” is with chips only available to experienced hams. Meanwhile, in the chips can be used to create simple devices to collect that it is easy even for those who make their first steps in Amateur radio.
Rocket 8К65 – single-stage, liquid-propellant rocket engine and with load-bearing fuel tanks. As propellants were first used hypergolic in contact with nitric acid (AK-27AND oxidizer) and unsymmetrical dimethylhydrazine (UDMH fuel). Flight control is performed by means of gas-jet rudders.
