Most of us spend a lot of time in hand with a soldering iron. Not a secret, that a good soldering of components is key to successful operation of the electronic device. soldering quality is determined by the characteristic luster. Grayish and uneven solder is a potential cause of bad operation of the circuit. another important… Continue Reading
The proposed trigger (diagram in Figure below) differs, that in one of its states, it almost does not consume current. It made it through the transistor optocoupler 4N35. Resistor R1 limits the base current of transistor its U 1.2 at a safe level, R2 protects… Continue Reading
The proposed device constantly monitors battery voltage the battery during its operation, preventing deep discharge, prejudicial to the state of the battery. Limiter discharge disconnects the load from the battery when the voltage drops below a predetermined threshold value. Description of similar purpose devices published in… Continue Reading
All chassis, which are equipped with TVs, assembled in China or in the CIS of Chinese parts, It never failed to meet not only the concept of, but often even the internal structure. This is because, that the data are standardized chassis (universal), produced in factories,… Continue Reading
Due to the low latitude and a large number of sunny days per year, The United Arab Emirates is an ideal place for solar energy development. It is therefore not surprising, что в этой солнечной ближневосточной стране вступила в строй самая большая в мире солнечная… Continue Reading
