In the multi-individual homes usually have Autonomous water supply system, which consists of a boiler, pipes, radiators and the surge tank. The inner walls of the tank is always wet from the constant evaporation and wetting with the expansion of water in the heating system. The reservoir is intensely rust inside and rust and fills the system, threatening congestion.LIKE A GLOVE IN HAND
A simple device consisting of a Board with a cutout, makes it easy to remove the tight boots. To give the required level from the floor under the Board attached to a wooden block, and the neckline is edged cut rubber tubing to avoid damage to the shoes.





Even in the recent past 10АС9 sound system, each sound column which contains two versatile dynamic loudspeaker (one for low and medium frequencies and the other, with a diffuser of smaller diameter for higher), it was considered perfectly acceptable for a home stereo. And electrical parameters it was on a high level: power 10 W, impedance DC current 4 ohms, audio frequency response 40 to 18,000 Hz. With the advent of so-called Hi-Fi equipment these speakers have become increasingly depart among the almost Museum pieces.

The homebrew is often used segments of rubber hose as a flexible coupling when connecting coaxial shafts, particularly in those cases where the rotation speed is small, and the shafts are not strictly coaxial. This way I decided to apply when I built the frame of the greenhouse from the chimneys of the old clamshells.
I offer a homemade device allows you to control voltage vehicle electrical system. In particular, that’s all right — the battery is charged and generates the required 12-14,8 V, the signal indicator is green light. At lower voltages the light turns yellow, and when elevated — red led.
