Before proceeding to the description of the snowmobile “Turtle-2”, will tell about the history of his birth. And it happened thanks to the ATV — the predecessor of the same name, only with index “1”.
Each constructor of RC models knows how many times spent the time to draw a wiring diagram. In a hurry is not always possible to sustain the necessary proportions between the individual elements, thoroughly implement the conventions. And then this scheme is not only messy, unsightly, but it often creep annoying bugs and inaccuracies. What to do in this case? To help here you can the cliches. More precisely, a set of moulds from which to select the desired image of the scheme. There are only about twenty: resistor, capacitor, diode, transistor, transformer, etc.
Fluorescent light (LDS) are widely used today in various industries and in everyday life. Unfortunately, the durability of LDS is extremely low. Their weak spot — helix required for the ignition of the phosphor inside the lamp at the time of inclusion. Two of them — from both ends of the lamp, and if even one of them burn out, to include LDS with the standard circuit (containing inductor, capacitor and starter) is impossible. In such a situation it is necessary to change the blown bulb with a new one. Therefore, where there are a large number of lamps (for example, in manufacturing plants, apartment buildings, stairwells and other similar cases), during the years of operation goes down and accumulates a lot of LDS with blown spirals.
Elastic tape used to seal the cracks in the frames of Windows and doors, you may find a different use, if there is a need in the hinges for the lids of small boxes or caskets. Enough pieces of tape to attach, using nails with a wide hat to the body and the lid: when Read more…
River passenger ships — a very numerous class of vessels. Small flights of ships to last several hours. Passengers are protected from the weather and can relax in the soft comfortable chair. Large vessels are often built specifically for multi-day journeys and equipped with comfortable sleeping cabins. Small have a small draught and a displacement of up to 80 tonnes, that allows to operate them even in the rivers. A model of such “microlayer” is very beautiful and has good driving characteristics.
Soldering chips easy electric soldering iron with special tip (see figure). For this presleyana copper rod of diameter 4-5 mm drill hole Ø 0,8 mm at the depth of 6 mm. Drilling is necessary, be careful, as copper is a viscous material and sloppy work is easy to break the drill bit. Perform soldering using Read more…
The French fleet of the late 80-ies of the XIX century, is familiar to specialists first of all thanks to Admiral Théophile OBU and his “young school.” Well known for their ideas of building naval forces: a Horde of destroyers, spread across ports and backed by armored coastal defense vessels.
In rural homesteads, and in ordinary suburban houses, which in mother Russia today Nemer-unread, without any stove — Russian, Dutch or a simple “stove” — is hardly a cost, even if “we have gas in the apartment”. Only still far not everywhere and not all have the “blue fuel”. But even if the gas is supplied, in the heat of summer to stand at the stove in the kitchen and prepare food — a handful. But have to do it, as you know, not once a day.
Getting a smooth surface — a long and laborious process. Cut it will help the sanding attachment on a drill, which is a cylinder with an oblique gap, which made the ends of strips of sandpaper.
At competitions of the Moscow schoolchildren model pupil of the 55th school Igor Svistunov in adverse weather conditions (wind of 6-10 m / s) scored 501 points. Only breaking model at the start of one of the tours did not allow Igor to achieve absolute victory outcome in all five rounds.
