We collect electronic housewifes for home

Electronic devices and devices of various kinds surround us. They are constantly next to us: at work, at home, and in the car. Manufacturers offer their options for all occasions. But there is no limit to imagination, and the master-amators invented them even more. These devices can be used for different purposes and in different places, and their assortment is simply amazing.

Schemes of electronic samovelok for both beginners and experienced masters in large numbers can be found in specialized periodicals. But among the great variety, you can always choose the most interesting thing. Therefore, in this article we will reflect only a few examples of such adaptations.

Motion Sensor

Electronic gadgets are designed to facilitate the life of people. Among them - all kinds of sensors that allow you to control the house remotely. One such example is the motion sensor.

They work on the basis of reflection pulses. If you enter the controlled area, the impulse will be reflected, and its characteristics will change. This will lock the detector, which monitors the output signal.

For a house, it is better to choose a thermal detector, since its components are more affordable. The assembly diagram does not cause any difficulties (it is shown in the figure below). And it can work in a wide range of temperatures. This sensor is suitable for monitoring luminaires, alarms and so on.

Replacement of incandescent LED

Incandescent lamps are available in every home. But now they are gradually being pushed out of the market. They are replaced by LED lighting, so there are already options for converting incandescent lamps to more modern and economical. To do this, you will need a 30 watt LED matrix , an aluminum sheet, a profile. Let's get to work:

1. To begin with, the lamp must be disassembled.
2. Then a circle is cut from the aluminum sheet, equal to its diameter.
3. It cuts off two small pieces of the profile. They are connected with rivets perpendicular to each other. The size of them must be such that they fit into the lampshade.
4. On the aluminum circle, mark the edges of the LED matrix (it should be placed in the center).
5. We make holes for rivets and fix the matrix.
6. On the inside we fix the profile. It will serve as an additional element for improving the heat sink.
7. The last stage involves the installation of a structure inside the plafond. It is necessary to connect the lamp wires to the matrix wires. After that, the lamp closes.

This self-made electronic ready for further use.

Tile with diode illumination

Electronic homemade for home amaze with its diversity and flight of imagination of the masters who invented them:

• The process begins with the laying of tiles in a traditional way. Only the seams between the tiles are not needed yet.
• The next stage of the work is the preparation of the wiring. For this, special connections such as "papa-mama" are used. The insulation of the wires will be carried out by heat shrinkage. Add to the wiring cross-shaped elements, which in their design have an LED.
• When all the wiring is assembled, it must be spread out in the grooves between the tiles. Install the LED is best at the intersection of the seams.
• After everything is decomposed, you can start filling the seams with a fugue. Only thus it is necessary to be very careful not to shift the LEDs.

Glowing Balls

Air balloons - a favorite attribute of all holidays. They have appeared for a very long time. But only recently their "life" has changed with the addition of "raisins". The fact is that the electronic games have affected them. Luminous balls will draw attention to yourself. It is not difficult to make them. To do this, you need: air balls in the amount of 5-10 pieces, batteries, at the rate of 3 pieces for each ball, and scotch tape.

1. The process starts with checking the polarity of the LED. To do this, it is placed on the battery. If it lights up, then everything is correct. If not - you need to change the polarity.
2. After that, the LED is attached to the battery with the help of an adhesive tape. The resulting design is placed in a ball. The same process is carried out with all the remaining balls.

These data are suitable for beginners. Almost everyone can do it.

Photo-relay on the principle of "day-night"

Lighting, which turns on and off on its own is very convenient. Schemes of electronic homemade offer to make a photo relay. A photodiode can be taken from an old computer mouse.

The principle of operation is quite simple. It is necessary to assemble the circuit as indicated in the diagram. It is suitable for the case when it is light. When a light emitted from the LED on the photodiode, a transistor opens. This leads to the fact that the second LED starts to glow. The sensitivity of the device is changed with the help of a resistor.

Electronic gadgets are a whole world that is completely unrealistic to know. You can choose only a few options that are suitable for each particular case. And if there is nothing suitable, you can always invent something of your own and share it with others.
