Do you like to work with your own hands? Electronics to help!

Electronics, in particular electronic household appliances, just burst into the life of a person and is so solid in it that it is simply impossible to imagine your life without such a mass of devices. So, for example, the older generation can not do without TVs, every evening they spend at TV screens, absorbing various shows and television series. And at this time, young people for ears will not be drawn from laptops, tablets, smartphones, all their attention and vital energy are absorbed by the world wide web called the Internet. But after all, some 50-60 years ago, not every home had a radio receiver, not to mention television sets. Progress does not stand still, it rushes forward not by leaps and bounds, but bursts into each house like a tornado, destroying the habitual foundations of a person's life and introducing confusion in the form of electronic devices and devices.

However, most people are only users of this technique, they do not have the faintest idea of how this or that device works, by what principle it works. Technical knowledge of such people is limited only to how to turn on the device in a network or put on a charge. But this science is very interesting and entertaining, and it's not at all difficult to learn how to make the simplest devices with your own hands. Electronics can open to you from a different angle. Having mastered the basics, you do not want to stop on the spot, you will develop and enrich your knowledge base, increasing your practical skills.

Of course, we must start with the simplest devices. So, by assembling the elementary scheme of a conventional doorbell with your own hands, the electronics of which will provide a frequency of sound or a melody that differs from all others, you will feel confident that you can move to more complex devices.

Let's look at how this is done in practice. For the assembly, we need two resistors (22 kOhm, and 180 ohms), one H310 field-effect transistor, a 50-25 V capacitor, one button, a speaker and a 9-volt current source. In this circuit plus supply voltage, a resistor (22 kOhm) is applied to the control electrode of the transistor, the throughput channel of which is carried through a resistor (180 ohms), plus a speaker. The minus speaker is connected to the voltage source. Connect the capacitor between the negative terminal and the source of the transistor. This scheme is collected in five minutes, literally on the knee.

You can buy a manual for beginner radio technicians and make different self-made items by your own hands, electronics Which will please you a long time. Moreover, the quality of such products will be many times better than those of Chinese counterparts that flooded our stores. Not the last place in your practice can be occupied by automotive electronics, made by yourself. The advantage of this direction is that any tuning is very simple, and experts are taking huge amounts of money for such "chips".

For example, install yourself additional LED lighting in the car: under the hood, in the luggage compartment, in the cabin ... Or put the LED strip on the bottom of the car. This does not require any specific knowledge. Pick up yourself on the radio market LEDs with a voltage of 12 V. Today, such a product is presented in a wide range. It is possible to take diodes in the case, protected from dust, dirt, moisture, etc. And this device is fixed elementary - on a double-sided scotch.

In any car on the hood and in the luggage compartment there are buttons on the opening, here to them it is necessary to connect the positive LED wire, and the negative one to the car body. With this connection scheme, the light will only light when the dimensions are on, that is, at night. If you are not comfortable with this method, extend the battery from the battery and install an additional button. But how convenient it will be at night to look for something in the trunk or dig under the hood. And most importantly - you could do it yourself. Electronics is just a klondike of all kinds of ideas for modeling and tuning.

You can even teach your child's wisdoms or learn with him. This will help you to establish close contact with your son, because boys like to pick their pieces in pieces of iron, to collect various devices with their own hands. Electronics, or rather, knowledge in this area, they do not really need it - are desperately needed!
