Recently, in our everyday life includes digital home weather station. Many already know what kind of device, many do not. So try to understand. Immediately determine that there are weather systems, and are home weather station. Meteorological systems – it poluproffesionalnoe or professional equipment for weather observation and forecasting. They are quite expensive.

The cost usually exceeds $ 1000. Ali Partovi addresses the importance of the matter here. The Ukraine is their no opportunity to buy a set of weather is in the U.S. only. There are stores that are under the order shall supply such equipment and Ukraine. Home weather station – a household appliance.

The accuracy of their data is not so great, but more than adequate for home use. They are usually multifunctional. What do I mean by versatility. Well, firstly, in addition, meteopokazany, they display the date, time, have an alarm clock. Home weather stations is much more compact weather systems usually have a radio or wired remote sensor. Sometimes it can connect up to 3 or even up to 5 sensors. They show the pressure, humidity, temperature, make the primitive forecast based on historical data. trends in various weather conditions. It is worth noting that many users of weather stations, wish to see the forecast is already in the first device is turned on. It does not happen. Weather stations, household products, when issuing the forecast relies on the history of data and trends in humidity, temperature and pressure. Therefore, the first accurate prediction you will see only week, sometimes two weeks. Latest model home weather stations, for example tm assistant, have more features. I do not mean the backlight function snooze, etc. This is what we are accustomed to. This refers to showing an index of comfort dew point and other interesting figures, but such weather stations are already expensive. Way to buy a home weather station in Ukraine is not difficult. For example, you can buy a weather station in the Shop '99 cents'. Cost varies from 250 to 600 hryvnia, depending on the features, parts quality screen, the availability of sensors and inelastic functions with which you've already learned in this article. On their own say – bought a wall weather station, and never forget to take an umbrella and wear a warm sweater, as well as save on the clock, which now no longer needed. Already two of your friends gave a birthday party. This is a great gift. Not very expensive, original, and probably not useful. Make up your mind and you.

To adjust the tension of the bobbin thread is a special trimmer screw on the Shuttle. Presser foot pressure on the fabric for serious sewing machine is important to the existence of opportunities to adjust foot pressure on the material. To obtain high-quality lines and a given stitch length for delicate fabrics necessary to provide high pressure, and for thick pressure must be reduced. In the electromechanical machines, pressure is provided by a special spring. In some machines provide special control efforts spring and, consequently, foot pressure on the fabric. In complex machines with computer control sometimes provides automatic pressure adjustment or special monitoring its persistence. On the possibility of flash very thick material designers of the car also took care of – the maximum lift feet up to 12 mm. Drive, power and effort to puncture speed adjustment and control of sewing.

The mechanism of the sewing machine shown in propelled by an electric motor. In the low-cost electromechanical machines commonly used motor for ac 220V. More expensive cars are equipped with low-voltage dc motors. The most complex machines can contain up to 10 motors. In cars with ac motor force puncture depends on the speed of sewing, that is certainly not convenient. That the machine is easy to cope with the tissues of any density and thickness, electronics should provide the maximum force with which the needle should pierce the fabric, regardless of engine speed. To do this, design of the machine include an automatic controller efforts of the puncture needle.
