Modern craftsmen are capable of collecting both simple toys and complex, multitasking mechanisms. About how easy and quickly make electronic toys, interesting and useful electronic homemakers for home and car do it yourself - read below!

Simple electronics with your own hands: do spinner

Electrical engineering, today, is used everywhere to implement both practical and entertainment purposes. Some inventions (such as a smart home system) make a newcomer quite difficult. They require experience and in-depth knowledge of physics. Other designs are simple and accessible to beginner radio amateurs. So, for example, you can make interesting toys with your own hands - spinners whose sales incredibly increased this year.

To collect the toy you will need to stock:

  • Wooden billet size 9x4x1.2 cm;

  9. Clear bearing, and process its insides WD 40;
  10. Cut off the bolt cap, and fasten the axis in the bearing on both sides with nuts;
  11. Install the bearing into the seating hole.

Spinner is ready! The toy will be interesting not only for children. Adults will be able to use such an electronic: the device, rotating, will help relax or distract.

Uncomplicated electronic homemade schemes: Making an electric lion

It is enough simple and quickly with your own hands you can make an electric-connector.

Such a call will last long and will delight the ear. After all, when you click, it will be able to create signals of various frequencies and tonality.

Thus, the electro-call can be one-photon and multi-torrent.

On the ability of a call to reproduce the sound in one or more tonalities will influence the presence in the multivibrator radioconstruction scheme with two bipolar transistors. Consider the details of the electronic call scheme with a complex sound signal.

So, electronic homemade scheme will consist of such radio components:

  • Lowering transformer series TA;
  • Ring buttons;
  • Five alloy silicon diodes;
  • Electrolytic capacitor with a capacity of 1000 microfrades
  • Two electrolytic capacitors with a capacity of 10 microfrades;
  • Two stroke resistors with resistance in 470 kiloma;
  • Two mlts of resistors with a resistance of 10 kiloma;
  • Two mlts of resistors with resistance 33 kiloma;
  • Resistor MLT on 1 kilome;
  • Resistor mlt at 470 kiloma;
  • Three silicon-plenary transistors type 630d
  • Silicon-planar transistor type 630g.

The principle of operation of the device is simple. Pressing the button will open the third transistor of type 630d, giving the current to the fourth transistor of type 630g. This will create a primary signal. When opening a second transistor of type 630d, the third and fourth transistors will turn, creating a signal of another tonality.

Homemade do it yourself for the car

Autoelectronics, for today, has a huge demand. At the same time, homemade automation, often, has simple schemes, Easy performance and installation. What electrical sequels can be done on your own car?

So, with your own hands for the car you can do:

  • Dynamic turn signals using Kit DIY constructor;
  • Universal charger from old electronics;
  • Air conditioning based on water pump;
  • Withers with heating and much more.

The easiest way will be constructed backlight for safety belt locks. To do this, it will be necessary to dismantle, and disassemble the locks using a flat screwdriver. After that, with the help of a thermal stake in the locks, it is necessary to secure LEDs.

Each LED can be included through its current-limiting resistor: it will prolong the service life of the semiconductor light-emitting device.

After that, you should collect locks, and the wires that feed the LEDs, stretching under the seats to the ignition or the dimensions button through the cigarette lighter. At the request of the owner, the car lighting of the cabin can be supplemented with lamps that signal that the seat belt is not fastened.

Unusual electronic homemakes: binary watch with their own hands

You can make funny binary watches for your own hands. To do this, you need Arduino Platform. Electroschemes on this platform are characterized by simplicity and convenience, used for the manufacture of most electronic homemakes.


In addition, you will need a binary watch:

  • Real-time clock module on the DS1302 chip;
  • Diffuse LEDs with a diameter of 1 cm (20 pieces);
  • Resistors with resistance of 10 ohms (20 pieces);
  • Resistors with resistance in 10 kiloma (2 pieces);
  • Two clock buttons;
  • Case.

The case of the clock should consist of two halves, which can be made of wood, plastic, metal. It depends on what style will be your watch. Before making the case, you will need to assemble the LED matrix.

At the same time, each LED must be connected through its current-limiting resistor.

After that, the conclusions from the LEDs must be connected to the platform. The controller itself will need to connect to the real-time clock module. After that, contacts from Arduino and the module must be carried out to the clock buttons to adjust the time through the resistors with a par value of 10 kilomes. They will serve as loads. Under the end, you should connect the power cable to the diagram.

Useful homemakes with their own hands: How household scales are made

Today, in almost every house there are outdoor or kitchen scales. In order to independently make this useful measuring instrument, it is necessary to deal with its device and the principle of work.

So, to the external components of the scales include:

  • Web processor;
  • Housing;
  • Screen for readings;
  • Platform;
  • Legs.

The principle of operation of the scales is extremely simple. The load, falling on the platform, presses on it due to gravity, activating the strain gauge weight sensor inside the instrument. The strain gauge, in turn, affects the tesorressor, changing his resistance. The latter transmits a signal to an analog-to-digital converter. After that, the ADC translates the signal into digital and serves it on the microcontroller, which makes conclusions about the mass of the load on the platform, and displays the values \u200b\u200bto the screen.

When assembling the scheme, you must pay attention to the type of strain gauge sensor.

So, for the central location under the platform of outdoor, trade and technical scales, it is better to choose a single-point sensor. A block sensor is used to install on bending. At the same time, it is necessary to ensure that the strain gauge has a reliable connection to the ADC. Solution will solve the problem of connecting devices.

Radioshames do it yourself for home: Making an electronic lock

The electrician can serve to protect the house. So, today, the sites of self-delicacies offer simple radioshes of electronic locks for the front door. Open such a lock using the physical key will not work.

The simplest electrical system for the manufacture of the lock, usually, is based on the four-digit Johnson counter.

This scheme can be implemented in several variations. The most simple - using the chip 4017. The principle of operation of the circuit is quite simple: when entering the correct code consisting of four digits, a logical unit is activated at the input of the chip, which opens the lock.

Consider the operation of the device more details:

  • When you press the wrong keys, the diagram is restarted without the operation of the mechanism through the RESET entry.
  • The correct signal, when you press the key, should enter the VT1 field transistor, which, after opening, supplies the output to the appropriate key;
  • After the correct introduction of the correct code, from the output corresponding to the last right key, the signal is fed to the VT2 transistor connected to the relay;
  • The transistor is activated for a time that determines the capacitance of the capacitor;
  • The relay opens the actuator (for example, a latch).

In order to open up such a castle, you need to go through about ten thousand different codes. At the same time, the numbers on the code should not be repeated. That is, the code 3355 will be impossible, all digital values \u200b\u200bmust be different.

Most of the electronic homemakes that are manufactured by modern masters are designed to perform the usual household tasks faster and high quality authentic devices. So, for example, it will significantly speed up the process of creating an electric stroke yarn. It is possible to quickly make electrical shields by putting an electric feed on an authentic device.

At the same time, the engine for the electrokeum must have a power of at least 15 watts.

As an engine, you can use the motor from the fan, the fan, the player. To activate the engine, use the pedal. You can change the motor movement by including a TP type toggle switch to connect a condenser and resistance to different windings.

Useful, easy to assemble and operation will be an electric wobble.

In order to implement such a mechanism, you will need to collect a standard block generator. At the same time, it will be necessary not to forget to isolate the fluff stick.

Where to find amateur diagrams and homemade

Modern radio amateur websites propose not only useful, but also unusual radios models. So, for example, on the brains website, you can find interesting radio-electronic schemes for the manufacture of reminders for the refrigerator, thermometers that change the color depending on the temperature, etc.

Interesting and helpful will be electrical things for life and crafts from girlfriend for fishing from the site "Visiting Samodelkin".

On how to design, debug and make electronic mechanisms at home, you can read in the book "Entertaining Radio Electronics". NEWs among radios models often posts the website of the Radio Worker's Workshop. Employed and useful technical materials contain new issues of the magazine "Radio Piters".

Homemade with your own hands at home (video)

Radiate mugs enjoy today, popular with both schoolchildren and adults. Master classes and radioches presented on various sites make it possible to collect almost any electrical appliances at home. The main thing is to find the necessary schemes, to clearly follow the instructions, and adhere to the safety technique when working with electricity. And you can collect everything you want!

For those who are just starting to make the first steps in electronics, it is important to start with something. Well, we suggest you familiarize yourself with the ideas that can come in handy in the future and at the same time will give an idea of \u200b\u200bhow to do something. What to choose if there is a desire to make simple with your own hands? Here are the options that can be used in everyday life.

Simple power regulator for smooth power on lamps

This type of device has been widely used. The easiest is an ordinary diode that is turned on sequentially with the load. Such regulation can be used to extend the operation of the incandescent lamp, as well as to prevent the soldering iron overheating. Also can apply them to change the power in a wide range of values. First there will be the most simple electronic homemakes with your own hands. Schemes you can see here.

How to protect yourself from network voltage fluctuations

This device turns off the load if the mains voltage goes for the permissible limits. As a rule, within the framework of normal, deviation is considered up to 10% of the regulatory. But due to the peculiarities of the energy supply system in our family, such a framework is not always observed. So, the voltage can be 1.5 times higher, or much lower than necessary. The result is often unpleasant - the instrument fails. Therefore, there is a need for a device that will turn off the load earlier than something will have time to burn. But when creating such a self-made must be careful because the work will be carried out with a significant voltage.

How to make a safety transformer

In various electronic structures, tang-transformer power supplies are often used. Usually such devices have a small power, and to avoid electricians, they are placed in an insulating plastic case. But sometimes they need to be tuned, and then there is an opening of protection. To avoid possible injuries, use the unleashing security transformer. It will also be useful when repairing such devices. Constructively, they consist of two identical windings, each of which is designed for the network. As a rule, the power of transformers of this type varies in the range of 60-100 W, these are optimal parameters for adjusting different electronics.

Simple source of emergency lighting

What if it is necessary so that in the event of a power failure, the illumination of some kind of plot has retained? The response to such calls can serve as an emergency lamp, performed on the basis of standard energy saving lamp, the power of which does not exceed 11 watts. So if it is necessary that the light be somewhere in the corridor, a utility room or in the workplace, this homemade will have to be placed. Usually, if there is a voltage, they operate directly from the network. When it disappears, the lamp begins to function on the battery energies. When restoring the voltage in the network and the lamp will work, and automatically charge the battery. The best electronic homemakes with their own hands were left at the end of the article.

Warming Power Controller

In cases where it is necessary to solder massive parts, or a network voltage is often reduced, the use of the soldering iron becomes problematic. And to help out this situation may increase the power regulator. In these cases, the load (i.e. soldering iron) is powered by rectified network voltage. The change is carried out using an electrolytic capacitor, the container of which allows to obtain a voltage greater than 1,41 network. Thus, with a standard voltage value of 220V, it will give 310 V. And if there is a drop, say, up to 160 V, it turns out that 160 * 1.41 \u003d 225.6 V, which will optimally act. But this is just an example. You have the opportunity to make a scheme suitable for your conditions.

The simplest twilight switch (photoorela)

As new items are created, it is now necessary to make less and less components to make some kind of device. So, for the conventional twilight switch, they must be needed. 3. With the versatility of the structure, multipurpose use is possible: in an apartment building; For lighting the porch or courtyard of a private dwelling, or even a separate room. Indicating the features of such a design as a twilight switch, they call it more "photowork". You can find a lot of implementation schemes that were made or lovers, or industrialists. They possess their set of positive and negative properties. As negative properties, it is usually called or the need to prevent the source of constant voltage, or the complexity of the diagram itself. Also, when buying cheap and simple details or integer kits, they often complain that they simply burn out. The scheme functionality is based on three components:

  1. Photocell. Usually under it understand photoresistors, phototransistors and photodiodes.
  2. Comparator.
  3. Simistor, or relay.

When there is daily lighting, the resistance from the photocell is small, and does not exceed the triggering threshold. But it is necessary to darken only - as the design will be included in the present moment.

Conclusion

These are interesting electronic homemakes with their own hands you can do. The main thing in cases where something fails is to continue to try, and then everything will succeed. And gaining experience, it will be possible to switch to more complex schemes.
