It is difficult now to imagine urban and rural life with no running water. Well, if the centralized water supply there, and the next well, the simplest solution is to use to lift water the pump. However, this is half the battle. The water supply system of the house should include a holding tank, and elements of the automatic control pump, and supplies network. Because of that design decision here can be very diverse. About some of them today to tell our readers.
If in your workshop or garage is no place to neatly place the tools fix the spring clamps on the folding shelf. In the off position, the tool locks firmly turntable or special latches located in a comfortable place in the latter case, the regiment becomes a kind of safe, inaccessible to attackers.
In modern modeling foams of various grades are used. This is understandable: the material has very little density, and its strength is comparable with some types of wood. But in the processing of foams is not always possible to recognize a convenient. The pupil 8-go a class Andrey Redko from the station in Samarkand region Read more…
This device whose description was published in the journal “Funkamateur” (GDR), used in various measuring devices or equipment, where necessary intermittent light or sound alarm. Moreover, the load can be connected both with the positive and the negative pole of the power source.
Do not rush to dispose of the waste battery “Krona”! It will serve more on your model. No, not as a newly charged power source for radio remote controls. Her shell will not hide the electrical energy, and fuel for model engine. In short, the “Crown” can be a great tank for model airplane, car Read more…
Microgravity class F3A are becoming more popular. However, their production is possible only to experienced modelers. Teenagers need a compact, simple to assemble and easy to use flight model of a simplified scheme under the compression motor small cubic capacity. Initially, we expected it under domestic MK-17 “Junior”, however, due to the low location of the tank the motor was bad possivel fuel, and had to be replaced compression “Meteor”.
Odnokomnatnaya model well-earned position in the class F2A. At competitions it is hard to escape the thought that flies the same speed — they are so similar. The approved scheme is fully justified. Stretched the console closes a lot of plot cord”brake”, and the plot is moving with the greatest speed and therefore creating a short in the normal wing the greatest resistance. Other model parameters are chosen in a practical way and provide optimum characteristics of stability and controllability. However odnokomnatnoj the scheme has a distinctive shortcoming: if the engine stops the model immediately sharply losing altitude. Struggled with it, inserting the elements of the external console. They compensated for the increase in lift force of the left wing, arising from blasting his air screw. Eventually had to abandon for more, reducing the speed of the wing, opposed “Norov” speed skill of the athlete.
The original design of the apartment can be sometimes the most unconventional ways. For example, if you are doing repairs in the fall at the time of leaf fall, as a kind of stencil you can use fallen leaves. They applied a paint brush, and then they primatyvajutsja Fotoalbom to the wall. The resulting prints Read more…
Can you name at least one model class that is really available to everyone? Until recently the answer to this question could only be unequivocal: no.
In modern apartments small size of living rooms is not always, unfortunately, allow you to post full sets of furniture and equipment for pupils. That’s why often there are separate elements are augmented or enhanced section of furniture sets.
