Those who have read the jump by Charles Perrault or watched the cartoon “puss in boots”, remember how much trouble was the cat that didn’t want to catch mice… So it opened a white light — cats should catch mice, and mice hiding from cats. And of course, each of the parties, not wanting to be the loser, goes to all sorts of tricks: the cat sits motionless for hours in ambush, or repeatedly bypasses the possession; mouse cleverly disguises its burrow, satisfied with spare moves.CAT AND MOUSE IN THE MAZE

Ubiquitous electronics is steadily expanding its “activities”. Where yesterday it was considered “foreign”, today it becomes indispensable helper. Approval this fully applies to karting. Smooth engine operation and high speed, readiness “number one” at the start and scrupulous accuracy at the finish be possible in collaboration with the electronics.
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.
This is a safety alarm device (SLD) is designed to automatically alarm (electrozone) in the case of penetration of unauthorized persons in the protected object — an apartment, dacha, garage. It is more immunity and no false positives. The unit is powered by 12-volt battery GB1 of the eight cells that consume standby current less than 5 mA.
A modern casino with excellent gambling attracts many, but to go there dare not everyone. Another thing — home electronic arcade. Here and nice and safe and the costs are minimal. On how to initiate the creation of such games, says the factsheet, which draws on materials from the Bulgarian periodical “Young designer”.
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.
(The end. Beginning at No. 9 and 10,’01). Electronic watch embedded in an improvised universal apparatus for charging batteries differ from the standard. Instead the category “des. min.” in the output “0.1 CH” is the idea of time is here more convenient for rapid calculations. The maximum count value “of 99.9 h.” Instead of the oscillator used household electricity 50 Hz, and the input of the amplifier-limiter is used for formation of the steepness of the pulses removed from the secondary winding of the supply transformer.
One of the problems for the citizens-owners of vehicles is the condition of the batteries. Frequent stops on subsequent runs of the engine discharged battery, a full charge from an onboard generator is at best one hour. And, as experts say, only 90 percent of waste of electric capacity is restored quickly, for some ten or fifteen minutes. The line current is reduced, and further the charge is delayed.
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”.
Generators of low frequency oscillations, as is known, can be used as a caretaker: intermittent loud noises warn of the approach of a stranger. On the same principle and made our “Keeper”. It is assembled on the transistor T1 and the transformer TR1 (Fig. 1). Load — the loudspeaker TP1. The chain of positive feedback R1, R2, R3, R4, C1 provides periodic self-excitation of the generator.
