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”.REPAIR “VYATKA-AUTOMATIC”

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.
The principle of operation of my proposed homemade svetvincenat “Whelan” is forced Ventilation of the Lamp bulb and heat the bottom of the room with warm air by sending heat to the floor, which is the “waste” of the light source. Moreover, the “Whelan” cleans the air from dust. And the lifespan of the lamp filament is thus significantly increased.
Fluorescent lighting is much more economical and durable than conventional incandescent lamps. Especially when equipped with modern fluorescent lamps (LDS) with a cap, which fits easily into familiar to all electroputere, and a tubular helical radiator, not exceeding in size the usual tube stellabelle.
In the old days, when required to perform switching in the electric circuits when the voltage rises to a certain threshold, resorted to the use of polarized electromagnetic relay. However, the substantial size and weight, lack of reliability of the kinematics and contact pairs severely limited the use of these devices. Now in their place came a miniature non-contact thingies called discs. This four-layer semiconductor diodes whose structure is like a two transistor: p-n-p and n-p-n type, with the base of one is connected to the collector of the second, forming the internal positive feedback (Fig. 1).
