After reading No. 1 “M-K” for the year 1989 description electronic switch-off “weight” of the car, decided to use it as a simple anti-theft tool. However, the replacement of toggle on the button (as advised by the project author V. Arapov) or reed switch occurs very undesirable moment when the voltage produced by the generator will be equal to the battery voltage, the transistor closes. And in the future on-Board vehicle network will be powered by only one generator. And as for fuel economy the engine is regulated to the minimum idling speed, the voltage generated by the generator in this mode, will be low. Therefore, at the moment of starting off (as in a “weak” generator, and when the light is turned on) the engine may stall. But the main danger occurs when emergency braking, as when the engine stops, the on-Board system is de-energized and the brake lights do not burn!
ANTI-THEFT – IN 5 MINUTES
As a stand-alone power source flash FIL-46 I use a voltage Converter PN-70, manufactured by Kharkiv enterprises “ECHO”. In the process of operation of this device revealed its drawback: after charging the storage capacitor and ignition indicator lights, signaling willingness to work consumed by the inverter current decreases from 1.5 A to About 1 A, that is, the batteries are not disabled and continue to discharge. This leads to rapid failure. To stop the discharge of the batteries is possible by disabling the flash from the unit manually by taking out the plug from the socket or set forth in the chain of socket switch. However, both methods are inconvenient due to the fact that distract from the shooting.
Honeybees live on the Earth for over 10 million years. And of course, tried to adapt to the environment in the wild but not at home… From hibernation they often go weak, susceptible to infectious diseases. And even whole families die. Although, it seems, and here nametype has, as they say, your height. Beekeeper-inventor and long-time subscriber “M-K” S. Kalashnikov developed an original method allowing the bees to facilitate the winter, they create a truly comfortable environment with the use of additional (electric) heating of hives.
Many plants, like tomatoes, during its growth and fruiting require a lot of moisture, so they often have to be watered, especially in hot season. The proposed machine will help you save valuable time and eliminate the need to be constantly “tethered” to their Pets. Just turn on the power and set the clock correct time of watering. The device is simple to manufacture, and at the same time it is reliable in operation.
When using electrical appliances (e.g. electric light), there is an inconvenience: you want to sleep but have to get up to go to the outlet and remove it from the fork. The proposed electronic device allows you to control (turn in work on or off) of various household appliances at a distance of just spoken sounds. Suffice it to say a certain word and please: earned (or stopped) the radio or television; lit (or extinguished) electric lamp or Christmas tree garland.
In my opinion, the most effective seem to be those developments that do not need to “up from zero”: we will focus on improving ready-made industrial electronic devices on their own. The result is a very modern functional design, one of which I bring to your attention. This is an additional node to industrial flash SEF-1 produced once the millions of “copies”.
For several years Samsung cell phones are available with the new universal (multi-function) mini-connector. Compact and flat (see photo), it provides charging from the adapter, connecting headphones, connecting to USB port of personal computer (“data cable”) to operate the phone as a modem and many other features.
One of the inconveniences in the design of many cars is that the interior light goes out immediately when closing the doors. There are, however, a special device to delay the power light on 5-15 that the driver had time to explore the dashboard controls and to insert the ignition key. But these developments are usually complex and expensive. And reliability often leaves much to be desired.
