SECOND COUNTS… “MOUSE”

COUNTING SECONDS... Currently available a variety of models of wall elektromekhanicheski quartz watches with stepper motor. They are, as a rule, uses unpackaged integrated circuit — the oscillator/divider with an external quartz resonator coated with black compound. And had to happen that this e-node has failed in the clock, served me faithfully for years.

ECONOMICAL VELOPLIVD

Almost all designs drive bikes have a common drawback that reduces their efficiency. This defect is uneconomical expenditure of muscular energy in the change efforts from one foot to the other during the passage of the pedals ‘dead spots’ (the vertical position of the connecting rod). A large part of the muscular effort at this point is directed to the axis of rotation of the pedals and not so much does the useful work, how much increases the wear of the bearings of the carriage. No wonder the cyclists before the withdrawal of the rods from the vertical position. As a result the course begins with partial loss of muscular energy, which causes premature fatigue of the cyclist.

THE FASTEST FIGHTER AIRCRAFT OF THE SECOND WORLD

THE FASTEST FIGHTER OF WWIIThe priority of the German aircraft industry in jet aircraft does not diminish the role of other countries that have joined before the Second world war in the “reactive” race. And each of them has contributed to this difficult process. Am Cradle started to design the turbojet engine (TRD) in the mid-thirties of the last century and do not start a war, probably would have completed it before.

THE EFFECTS UNIT IS FOR SOLO GUITAR

EFFECTS UNIT FOR Before describing the operation of the device as a whole will focus on one of its constituent elements — the Converter of the spectrum of the electrical signal, or “FUZZ”device. To To obtain this effect, it is necessary to enrich the original signal a large number of odd harmonics. There are several ways, and thus the schemes to achieve them. We will stop at the spectrum Converter, which is a ULF with parapremium.

A FAILED “DOUBLE”

UNSUCCESSFUL The unsuccessful Russo-Japanese war caused a powerful flow of criticism and accusations against Russian warships, primarily cruisers. The unenviable fate of our clumsy “goddesses” swift and graceful “shestidesyatnikov”, most of them internetoffice after receiving not too extensive damage, gave rise to attacks on the very type of ocean-going armored cruisers. Somehow “suddenly” found that such ships are not able to fight in line battles (which, however, they never intended). Specialists and idle public organizations began to look for their ideal. And, in the end, found in the person of the only armored reconnaissance squadron, the cruiser “Bayan”. Meanwhile at the appearance of this cruiser does not cause such enthusiasm.

SLIDING OVER THE WAVES

Ships rise into the air. From the moment when the English hovercraft (SVP) CR.N1 in July 1959, crossed the 32-mile Strait of Dover (or the better-known us — Pas-de-Calais) between the ports of Calais on the French coast of continental Europe, and Dover on the island Kingdom, its inventor Christopher Cockerell became famous all over the world…

TWO SHEETS OF PLYWOOD AND A DINGHY!

TWO SHEETS OF PLYWOOD AND A DINGHY!If you live not too far from the pond, make our drawings Dinghy, and you will experience all the delights of sailing. But if this ancient engine is not too attract you, the body of the Dinghy can be used as the basis for small motor boats or rowing Dinghy. Materials for it will require only two sheets of plywood and pine slats.
