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”.
Not every radio has a built-in protection against so-called “polarity” and incorrect connection to power supply with a known high voltage (which is necessary, unfortunately, to encounter, such as faulty alternator in the car). And payback can be the output of this equipment failure.
Inspired by the originality of technical solution, published in the journal “modelist-Konstruktor” No. 11’78, I modified the circuit for fluorescent lamps and for many years its use in residential lighting fixtures. As in the prototype, economical and not scarce ЛДЦ40 (ЛДЦ80) light up instantly, their work is not accompanied by annoying clicks and “wink” for missing an unreliable starter. And best of all — for such lighting you can even use the bulb.
It happens that the recorder or the player when you rewind the tape “do not pull” due to the large current hooked the batteries. And in many electronic games such as, Brick game (“Tetris” in China), when you enable sound for the same reason, begins to noticeably flicker LCD screen.
Hams, self-repairing computers and modern means of automation or manufacturing such equipment, are faced sometimes with the need to record information in the chip programmable logical matrices (PLM). With similar problems they have, for example, to meet when you combine the joystick with the keyboard on the basis of MC КР556РТ1 (КР556РТ2). However, it may be that the existing programmer (even among the so-called universal) are not designed for firmware of these chips. To buy new, more specialized and costly electronic device is not always justified. Another thing is to modify what is already at hand.
I am convinced that any device with power supply-battery flashlight will only benefit if you provide it a makeshift terminals, providing reliable electrical contact in the connection to the battery. Moreover, the time and cost it takes a bit.
