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.CAREFUL THE WHEELS
To cut large office furniture comfortable when placed on the wooden trestles. However, in the process, the surface of boards can get scratched. To prevent this, wheels should attach a few scraps motorcycle or Bicycle tires: they will prevent the polishing or plastic lining shields from scratches.
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.
