In the mixer tap in the bathroom sometimes breaks the pin on the shower switch cold-hot water. In the store it is almost impossible to find, and a new faucet is expensive. It is fixable.
The idea of compression of air and practical use of its in new condition not new. Alexander Belyaev in his work “the Seller of air” introduces us to the prospects of this direction. The hero of his works Bailey clutched the air in the balls and kept them at a temperature equal to absolute zero.
If the stock is illiquid. burden burden of low-power portable radio (or a set of two stations), designed for communication in civil band 26,9 — 27,2 MHz, offer the option of their useful lives. Often, ham radio is both a car owner and cottager, who, as a person concerned for the safety of your car or suburban house. Besides there are many other areas of application of the proposed security devices on the basis of two portable radios. The main difference from other security systems is that the “alarm” signal is passed through the radio channel and range of action of the protection system depends on the power of radio transmitters and features of the passage of radio waves in the area of application of the system Even if there is only one radio station (CBS stations), is also not a problem as the receiver can use an all-band multimode transceiver type Kenwood FH-7E, Yaesu or similar (more about that below) in the circumstances, the transceiver is programmed to receive the appropriate frequency 27,175 MHz. Automatic shutdown function in the transceiver neutralized.
Party NTTM, army innovator Y. Bandurko, suggested a simple device for cutting steel wire rope. Steel is the base plate to which are welded crosswise arranged vertical edge guides. Between them with the edge of the knife upwards to fit the bar, he lowered the rope, and the top plate is inserted into the mandrel. Then all of this fixture Assembly is installed under the press, the mandrel takes its stress on itself and presses on the rope, cutting it on the blade of the knife block.
Every housewife in the kitchen Arsenal are the rolls of napkin paper or foil. But to use them and store them without special tools is not very convenient. Make a simple stand — and you will forget about these inconveniences. It consists of a wooden base, sawn from any of the Board, and of a Read more…
It would seem that not so long ago appeared in our kitchens “blue light” — the first of the Saratov gas. The enthusiasm that accompanied the displacement of them wood-burning stoves, kerosene stoves and kerosene stoves, over time, subsided. Gas was not an ideal fuel for stoves. The allocation during the combustion of harmful substances, the constant danger — and suddenly blow out the flames the wind and the room is filled with explosive mixture, — all this has led to the fact that gas stoves were gradually superseded by electric. The advantages of the latter compensate for even that heat the burner costs a bit more expensive.
To debug transistor-based hardware is much easier if you have the regular store stable voltages. Two adjacent shoulders of the bridge rectifier V1, V2 connect the unit Zener diodes V3 — V8 and V9—V14, V15 — V20, V21 —V26 or V27 — V32 (Fig. 1) exercising, in addition to rectifying the current, stabilization of the output voltage 7, 8, 9, 10, 12, 14, 16, 18, 20 or 24 V at a current of 30 mA. When the input voltage is within 110 — 240V output changes by 0.2 V and the current is 1 mA.
This advice will be useful to those involved in the drinking of low-melting materials. Take a spare soldering tip high power (over 65 watts), flatten the end and rivet it to a steel stamped Cup — for example, the wheel cover of a stroller or a spoon of suitable shape. Align the hole in the Read more…
To create a device is simple, inexpensive to perform and at the same time with high performance — such is the aim of gliders. We offer our readers the description is very promising glider “Albatros” open class, created by Moscow engineer A. Z. by rabanim in early 1978. This device has been widely tested and has a high aerodynamic qualities. From other phones open class “Albatross” stands simple design (all tube frame straight), in combination with precise profiling of the dome, which provides pre-curved armor combined type (front — hard, back — elastic). The frame of the Albatross allows you to apply domes of different shapes and size without any alterations and additional adjustments.
His appearance holder, obviously, was due to the fact that it was not possible to attach the handle to the glass. Modern chemistry allows you to do this even at home. Take the glue BF-2 or “Moment”, and of metal strips vignette the handle In the part that will fit the glass and drill a Read more…
