Motorists know that if a car a long time not to use the battery terminals to prevent oxidation must be removed, and the open contact of the battery terminals to isolate. The easiest way — the usual plastic bottle caps. On the negative pin tightly put on the cap from a half-liter bottle, and on the positive — from 0.75-liter. Conclusions closed by such caps are not oxidized, and the battery is protected from accidental short circuits.
The motorist in the garage is always served its plastic canister, and the house oborotnivka three – or five-liter flask from under the water, throw which is a pity. But you can convert them to other usable, suitably by cutting. The neck will become, for example, in the funnel, and the rest .— in a Read more…
To make this model forces students 4-6 grades, first starting modeling. The first detail which you will need when building Navoiy 6. It is made of the housing 4 missiles and cap-cone 1. The last carved out of tree diameter casing.
Old but wise proverb says: “Bread is a head”. Here are only stocking it in store is hopeless. So very quickly it hardens and dries, and then becomes moldy and unfit for consumption. And as you know, especially the delicious fresh bread. But people still have not found a way its long-term storage without loss of taste—except that rusk. But the last mistress use rather of despair.
Increasingly, we receive letters from readers describing flying models, which instead of internal combustion engines operate motors of different systems. This is quite natural and timely: judging by many indications, the electrification of aircraft modeling – in sight. No wonder the first successful examples of flying models are available in the “toy” version of some foreign model aircraft firms. Among them are low-cost models, capable of conducting free uncontrollable flight duration of 1-3 minutes, Cordoba for the different types of food on the wire and even radio-controlled model of the coast, including the piloting. The duration of the last flight without recharging has managed to bring up to 10-15 minutes. However, the electric power is still inferior to compression and heat rating.
Anyone who has had to work with a shovel, knows how hard it is to dig the ground, overgrown with grass, covered with a dense layer of turf or “reinforced” by the roots of trees and shrubs. Even if the soil is relatively soft, flip kom turf will be down, just pull up on all Read more…
Boxes of nails and screws love to fall to the floor. This can happen by careless movement of the hand, and vibration of the table. However, if a box mounted on a vertical hinge bottom cover of a table or workbench, it will get rid of this bad habit. Rotate it around the hinge… and Read more…
Novice automodellista propose a simple model with a body made of thin stiff cardboard. Manufacture the body you need to start with drawing and cutting with the side walls of the pattern No. 1. To get the contours right and left walls, the pattern upside down. After cutting the parts beaten out from the inner side with a hammer, giving them a slightly curved profile. Longitudinal breaklines make incisions on half the thickness of the cardboard on the outside and the inside — on the dotted line.
The main aircraft for training pilots in the great Patriotic war was the U-2 (Po-2) and produce the resource UTI-4. Double export fighter I-7B, Yak-9 and La-7UTI in flight schools were a rarity — they didn’t even spare regiments, and training pilots on them was expensive. In this regard, in the war years in OKB-115, led by C. A. Yakovlev, began the future development of the Yak-18, which replaced the At-2 as a “school” pilots. However, future air fighters needed the aircraft for training their shooting at air targets and bombing.
More rapidly advancing digital satellite TV, coming to replace the bulky radioligand lines. The population of our vast country, even in its most distant corners, appeared a real possibility of a wide choice of television channels with excellent quality of image and sound. Therefore, a great demand began to use satellite receivers with antennas in the form of “saucers.” Installation of reception of the electronic equipment does not cause trouble, but with the installation of the antenna sometimes there are difficulties: for example, in the zones of “shade” trees, high buildings, etc. In some cases, the reception of the satellite TV signal even becomes impossible. There is a need to install antennas as high as possible to get out of the “shadows.”
