Development and manufacture of printed circuit boards for a single instance of a homemade device with a higher density of mounting becomes sometimes a problem even for the experienced radio Amateur. I have also found the opportunity to do without any preliminary layout of printed wiring conductors, and even without soldering electric and electronic circuits. I replace all of that… wrap.LAMPS WILL LAST LONGER
It’s no secret that halogen lamps used in automobiles often fail. This happens as a result of a current surge that inevitably occurs every time they are switched on, when the filament coil is still in an unheated (cold) state. For example, a “halogen” fog lamp is designed to operate in normal mode with a Read more…
Debugging any program of the microprocessor, it is necessary many times to write and erase information in the chips ROM КР573РФ5 (РФ5). However, the online those is very limited. In the end — quick exit of the chips from the system.
In the aquarium automation now the dominance of the expensive import, processors, chips, complex equipment… But is it always justified the cost of purchasing the advertised aggressively in the domestic market by foreign devices? And isn’t it better to return to the simple and reliable Russian designs? Among them can be attributed to the proposed technical solution.
Led bulb (abbreviated SL) can be seen today in almost every home. And for good reason-they are economical. Energy conservation is that SL, for example, with a declared capacity of 9 watts and current consumption of just from 0.065 A, is the analog of the output light of the incandescent lamp 60 W, which consumes several times more.
In 1907, English engineer Round, who worked at the world famous Marconi laboratory, accidentally noticed that running the detector around a point of contact there is a glow. Also seriously interested in this physical phenomenon and tried to find the practical application of “inconceivably talented Russian” — Oleg Vladimirovich Losev.
One of the common causes leading to failure of washing machines “Vyatka-automatic”, is the failure of motor windings (ED) the drive command device. In repair shops usually eliminate this problem by replacing. And I prefer not to deal with blown cheap update windings and not even with “soundriver” motor, and with expensive command device (SC), in which all of this is not subject to disassembly “monolith”.
