Useful accessories for your car with your own hands. Useful homemade products for your car with your own hands

Various homemade products for cars have always been of interest to motorists. All of them are designed to improve performance, appearance or comfort passenger car. For example, you can make a subwoofer, a convenient organizer, eyelashes for headlights, license plate protection, etc. with your own hands. We will tell you about some useful homemade products that are available to everyone.

Every motorist strives to make his car unique. This can be done with the help of unique overlays on the headlights, which are called cilia and add some zest to the appearance of any car.

To make your own eyelashes you will need the following:

• construction hair dryer;
• thick paper or cardboard;
• primer and paint;
• sandpaper;
• hacksaw;
• scotch;
• plexiglass.

First you need to decide what shape of eyelashes you want to get. The choice depends on your preferences and imagination. Draw a template on paper or cardboard and cut it out. You can use it to cut a piece of plexiglass in the future.

Attach the created template to the headlight of your car and give it a finished look by carefully fitting all the edges. When everything is ready, attach the template to the plexiglass and trace it with some sharp object. The part should be cut out along the resulting contour.

In order not to damage the headlights and protect them from scattering, it is better to cover their surface with tape. Use a hairdryer to heat the workpiece, and when it begins to bend, you can apply it to the headlight.

After this, the surface must be treated with sandpaper, moistening it with water. When everything is dry, prime the part and then paint it in any suitable color. Everything is very easy, and the result can exceed all your expectations.

If on rims If your car has scratches or chips that spoil the appearance of the product, you can take the wheels to a specialized workshop for painting. If you don’t want to spend money on this, you can try to restore the damaged areas yourself.

To work you will need:

1. Scratched discs.
2. Epoxy glue of any color, since a layer of paint will be applied on top. However, if the paste is too bright, it may show through the paintwork, so before applying paint it is better to prime everything thoroughly with a primer.
3. Sandpaper number 300-400 and 600.
4. Adhesive tape.
5. Spray paint and varnish.

First, using coarse sandpaper, you need to clean the places of chips and scratches to such an extent that you could not feel any bumps with your hand. We recommend covering the rubber with adhesive tape and covering it with newspapers to prevent paint from getting on it.

Mix both components of epoxy glue in a one to one ratio. Apply the mixture to the cleaned scratches so that the mixture completely fills them, and a thin layer forms on top.

Dry everything thoroughly. This takes a lot of time, and to speed up the process you can use heat by placing a fan heater or a simple incandescent light bulb near the disks.

When the glue has dried, sand it with fine sandpaper, preparing the surface for painting. Everything should be smooth to the touch and look - this is important.

Using a spray can, painting the rims is not difficult at all. You need to thoroughly shake the can and start spraying the paint from a distance of 20-30 cm. The paint should be applied in layers. Avoid too obvious transitions by applying two or three layers. Each of them needs to be dried, waiting for half an hour. To protect fresh paint from dust, it is better to carry out painting work in a pre-humidified room.

After the paint has dried, apply two coats of varnish. Between layers you need to wait half an hour, and the top layer should dry longer.

When everything is thoroughly dry, you need to moisten the finest sanding paper (1000-2000 grit) with water and carefully smooth the varnished area. To achieve factory shine, the surface can be polished.

The theft of registration plates today has become one of the illegal ways for criminals to earn money. It takes thieves no more than 10 seconds to steal license plates from a car. In order not to fall into the trap of scammers, you need to take care of protecting your registration number. There are several methods, each of which can be implemented independently at home.

Protect your number with tape

This method of protecting your license plate from theft may seem funny to you, but it is quite effective. The back surface of the registration number should be degreased and double-sided tape should be attached to it. This simple and inexpensive way to protect your plate creates an additional barrier for a thief to keep your license plate.

Secrets for car number

Instead of simple screws that secure the license plate, lockers are installed. The hats are designed in such a way that the secrets can only be unscrewed special key, sold together with fasteners. The kit costs about 500 rubles, and installation does not take much time.

Electronic homemade products, today, are an affordable way to manufacture useful mechanisms that can make life easier and diversify leisure time. Modern craftsmen are able to assemble with their own hands both simple toys and complex, multi-tasking mechanisms. Read below to learn how to quickly and easily make electronic toys, interesting and useful electronic crafts for your home and car!

Simple DIY electronics: making a spinner

Electrical engineering today is widely used for both practical and entertainment purposes. Some inventions (such as the smart home system) will be quite difficult for a beginner to make. They require experience and advanced knowledge of physics. Other designs are simple and accessible to beginner radio amateurs. For example, you can make interesting toys with your own hands - spinners, the sales of which have increased incredibly this year.

To assemble the toy you will need to stock up on:

• Wooden blank measuring 9x4x1.2 cm;
• Bearing size 2.2x0.8x0.7 cm (with rubber seal);
• Two RGB LEDs;
• Two CR2032 batteries and holders;

11. Install the bearing into the mounting hole.

The spinner is ready! The toy will be interesting not only for children. Adults can also use this electronic device: the device, rotating, will help you relax or get distracted.

Simple electronic homemade circuits: making an electric call

You can make an electric call quite simply and quickly with your own hands.

Such a call will last a long time and will please the ear. After all, when pressed, it will be able to create signals of different frequencies and tones.

Thus, an electric call can be single-tone or multi-tone.

The ability of a bell to reproduce sound in one or more tones will be influenced by the presence in the radio design circuit of a multivibrator with two bipolar transistors. Let us consider in detail the circuit of an electronic call with a complex sound signal.

Yes, electronic homemade circuit will consist of the following radio components:

• Step-down transformer series TA;
• Call button;
• Five alloy silicon diodes;
• Electrolytic capacitor with a capacity of 1000 microfarads
• Two electrolytic capacitors with a capacity of 10 microfarads;
• Two trimming resistors with a resistance of 470 kilo-ohms;
• Two MLT resistors with a resistance of 10 kiloohms;
• Two MLT resistors with a resistance of 33 kilo-ohms;
• MLT resistor 1 kilo-ohm;
• MLT resistor 470 kilo-ohm;
• 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, allowing current to pass to the fourth transistor of type 630G. This will create the primary signal. When the second transistor of type 630D opens, the third and fourth transistors will be locked, creating a signal of a different tone.

DIY crafts for the car

Automotive electronics are in great demand today. At the same time, homemade automation often has simple circuits, easy execution and installation. What kind of electrical homemade products can you make for your car yourself?

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

• Dynamic turn signals using the KIT DIY constructor;
• Universal Charger from old electronics;
• Water pump based air conditioning;
• Heated wipers and much more.

The easiest way would be to design a backlight for the seat belt buckles. To do this, you will need to dismantle and disassemble the locks using a flat-head screwdriver. After that, using hot-melt adhesive, you need to secure the LEDs in the locks.

Each LED can be turned on through its own current-limiting resistor: this will extend the life of the semiconductor light-emitting device.

After this, you should assemble the locks, and run the wires powering the LEDs under the seats to the ignition or the parking button through the cigarette lighter. At the owner's request, the car's interior lighting can be supplemented with lamps that indicate that the seat belt is not fastened.

Unusual electronic homemade products: do-it-yourself binary clocks

You can make cool binary clocks for your home with your own hands. To do this you need an Arduino platform. The electrical circuits on this platform are simple and convenient; they are used for the manufacture of most electronic homemade products.

Additionally, to make a binary clock you will need:

• Real time clock module on DS1302 chip;
• Diffuse LEDs with a diameter of 1 cm (20 pieces);
• Resistors with a resistance of 10 Ohms (20 pieces);
• Resistors with a resistance of 10 kilo-ohms (2 pieces);
• Two tact buttons;
• Frame.

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

In this case, each LED must be connected through its own current-limiting resistor.

After this, the leads from the LEDs must be connected to the platform. The controller itself will need to be connected to the real time clock module. After this, the contacts from Arduino and the module must be routed to the clock buttons to set the time through resistors with a nominal value of 10 kilo-ohms. They will serve as load bearings. Finally, you should connect the power cable to the circuit.

Useful DIY crafts: how to make household scales

Today, almost every home has a floor or kitchen scale. In order to make this useful yourself measuring device, you need to understand its structure and operating principle.

So, to the outside components weights include:

• Weight processor;
• Frame;
• Display screen;
• 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 load cell inside the device. The strain gauge, in turn, influences the strain gauge, changing its resistance. The latter transmits the signal to an analog-to-digital converter. After this, the ADC converts the signal to digital and feeds it to the microcontroller, which draws conclusions about the mass of the load on the platform and displays the values ​​on the screen.

When assembling the circuit, you need to pay attention to the type of strain gauge.

So, for a central location under the platform of floor, retail and technical scales It is better to choose a single point sensor. For bending installation, a block sensor is used. In this case, you need to ensure that the strain gauge has a reliable connection to the ADC. A weight processor will help solve the problem of connecting devices.

DIY radio circuits for the home: making an electronic lock

Electrics can also serve to protect your home. So, today, DIY sites offer simple radio circuits for electronic locks for the front door. It is impossible to open such a lock using a physical key.

The simplest electrical circuit for making a lock is usually based on a four-digit Johnson meter.

This scheme can be implemented in several variations. The simplest one is using the 4017 microcircuit. The principle of operation of the circuit is quite simple: when you enter the correct four-digit code, a logical unit is activated at the input of the microcircuit, which opens the lock.

Let's take a closer look at the operation of the device:

• When the wrong keys are pressed, the circuit restarts without triggering the mechanism through the RESET input.
• The correct signal when pressing a key should be sent to field-effect transistor VT1, which, after opening, supplies voltage to the output corresponding to the key;
• After the correct code has been completely entered, from the output corresponding to the last correct key, the signal is sent to the transistor VT2 connected to the relay;
• The transistor is activated for a time that determines the capacitance of the capacitor;
• The relay opens an actuator (for example, a latch).

In order to open such a lock, you will need to go through about ten thousand different codes. At the same time, the numbers on the code should not be repeated. That is, code 3355 will not be possible; all digital values ​​must be different.

Most of the electronic homemade products that modern craftsmen make are designed to perform ordinary household tasks faster and better than authentic devices. For example, an electric spinning wheel will significantly speed up the process of creating yarn. You can quickly make an electric spinning wheel by placing an electric motor on an authentic device.

At the same time, the motor for an electric spinning wheel must have a power of at least 15 W.

As a motor, you can use a motor from a fan, auto cleaner, or player. The pedal must be used to operate the engine. It will be possible to change the movements of the motor by including a TP-type toggle switch in the circuit, which provides connection of a capacitor and resistance to different windings.

An electric fly swatter will be useful and easy to assemble and operate.

In order to implement such a mechanism, you will need to assemble a standard blocking generator. At the same time, you will need to remember to insulate the handle of the fly swatter.

Probably all drivers have at least once forgotten to turn off the direction indicators after performing a maneuver? Standard clicks from the front panel are not always clearly audible, especially if there is music playing in the cabin, so I suggest adding a simple turn signal signal circuit to your car with your own hands.

The cigarette lighter is one of the few car features that has retained its original design for more than 70 years. As a result of this, both rare cars and the most modern models the same design is used. Of course, in the old days this device was used only for one function, although now in the modern “information world” it performs different functions, for example a connector for charging various digital gadgets or even starting a car.

Amateur radio circuits for turn signals are designed to work only with LEDs in your car's brake lights; if you are still using regular bulbs, you can easily replicate the design of the turn signal. Simple development" Brake lights" - a homemade time relay will turn off the latter if they are on for more than 40-60 seconds, and turn signal relay upgrade 495.3747 will allow you to enter into standard equipment VAZ or GAZ LEDs instead of incandescent lamps.

The proposed first option for upgrading the car windshield wiper relay has more high reliability operation, can provide dynamic braking of the engine.

Install a humidity sensor and water drops falling on it will automatically trigger the circuit.

A car monitor with rear view cameras is very important element in your car, because in modern urban realities you need to be a parking master to find a place to park your car. An example of installing a monitor in a car visor is clearly shown, which makes the image optimally positioned for the driver’s eyes.

Nowadays, the issue of accounting and saving energy resources, including fuel for vehicles, is more pressing than ever. From a wide variety of devices that take into account fuel consumption, greatest distribution received devices with a recording element of the sensor in the form of an impeller. Sensors with a different measurement principle, although they have sufficient accuracy, are difficult to manufacture and have disadvantages. Practice has shown that sensors with an impeller, made with the necessary and sufficient accuracy, can operate for years without requiring maintenance, with a registration error below the tolerance for this type of device

The ignition system is a set of various automotive instruments and devices that generate an electric spark to ignite the air-fuel mixture in the engine cylinders internal combustion when turning the ignition key. On this page you can find various schemes connecting the ignition of VAZ cars. As well as homemade amateur radio versions of the electronic ignition circuit

It has the following advantages: the spark power is increased, the breaker contacts do not burn; no resistor is needed in the ignition coil circuit; when the ignition is on, but the engine is not started, the circuit smoothly without a spark turns off

In the Soviet automobile industry, the RS57 type turn signal interrupter was of an electromagnetic operating principle and was used to ensure the flashing of warning lights, which makes the turn signal more visible and noticeable to other road users. The turn signal switch is connected in series to the turn signal circuit. Within the framework of the article, we will consider options for replacing this electromagnetic device with its electronic analogues.

Probably every car enthusiast forgot in the warm season to close the windows in the car, so that this does not happen again, I suggest putting together a circuit designed to automatically close all the windows in the car when the alarm is set. Let's look at a few possible options implementation of the design from simple circuits from a relay to an automatic window control on a microcontroller.

But there are a lot of negative effects abrupt start, which over time affects the electrics of the vehicle. This article describes a diagram of the relay replacement option smooth start cooling fan.

Carburetor economizer device

Carburetors were installed on cars for many years until they gradually made way for various fuel injection systems. But the automobile age Russian cars long, and still have to deal with vehicles that still have a carburetor. Well, as you know, its normal operation is ensured by several devices, the main one being a fuel economizer. This is exactly what we will talk about, and also consider the diagram of the forced economizer system idle move for VAZ cars

A car starter is a device that allows the engine to start after turning in any weather conditions. Almost all starters, in their essence, are conventional short-term electric motors, but of high power. The starting cycle of a typical device consists of three attempts with a 30 second interval between them. Since the car has a single source of electricity (the battery), the engineers chose a DC electric motor for the starters.

Every car owner who was driving budget car knows how long to wait for heat to come from the engine when it warms up winter time year, especially if you live in the northern part of the most big country peace. It takes about 30 minutes to reach a comfortable temperature, and this happens every morning. Best idea The solution to this problem, in my opinion, is to heat the car interior with a fan heater. An old and faulty toaster helped bring the idea to life computer unit nutrition.

In winter, many Russian drivers begin to experience a time when driving a car requires a preheated engine. A car antifreeze heating circuit helps solve this problem. The first one discussed is quite simple to repeat.

A heated steering wheel, along with heated seats, mirrors, and windows, is not a luxury these days, but an indicator of the level that a person lives in a civilized country. All of the above parameters in a personal car are very convenient, and help the driver to concentrate only on driving the vehicle, and not on his frozen fingers.

This design is designed to generate a sound signal when moving trucks and buses back, and a sound signal warning of danger begins to be generated automatically.

The main advantage of the second battery is that the accumulated energy is consumed through an additional battery, and the first one is in reserve, that is, you don’t have to worry about starting the car after a picnic far from civilization. Many foreign cars already have a second battery under the hood. Their only drawback is the parallel connection of 2 batteries

This amateur radio design is suitable for charging most smartphones and tablets from 5 volts, even when the ignition is turned off. Or it will allow you to power the DVR for 40 minutes, while the car is waiting for its owner in the parking lot. The basis of the circuit is the AVR Tiny13 microcontroller, the firmware is attached to it.

There is no limit to perfection. This saying is well known to one and all. And any car owner strives to make his car perfect. For many drivers, the factory settings are not enough. They strive to bring something of their own. Something that will set them apart from the rest. But what to do if what you want cannot be purchased in the store? There is only one way out: if you can’t buy it, do it yourself.

They have become very popular lately. They improve the appearance of the car, change some specifications or bring pleasant additions to the options. Among the variety of possible alterations, we suggest considering several options.

Car wash

Let's start with the appearance. When a car is clean, its paintwork shines and shines. It's nice to look at this technique. You immediately get the feeling that the owner is taking care of his car. But going to the car wash is not always possible due to various circumstances. In such cases, homemade car products will come to the rescue. You can assemble a small sink with your own hands, which you can use at any convenient time.

To make a sink you will need the following parts:

• canister with two drains;
• hose 2 m long (suitable for connecting a washing machine);
• watering gun with telescopic rod;
• union;
• spool;
• rubber gasket (outer diameter 2.4 cm, inner diameter 1.5 cm);
• coupling.

Now let's get started:

1. We make a hole in the lid of the canister. We coat the “spool” with sealant and insert it into the prepared hole in the lid. Let it dry.
2. We make a small hole in the second lid. It is necessary for treating the connection between the cover and the coupling with sealant and also allowing it to dry.
3. We cut off the nut with fastening from the curved end of the inlet hose. No need for fastening anymore. Apply sealant to the nut and secure it with reverse side couplings. We connect the cut side of the hose to the nut of the quick-release fitting. Next, the main fitting is screwed in, which is also connected to the watering gun.
4. On the second side of the hose, insert a rubber gasket into the nut. This will protect the system from air penetration. After this, the nut is screwed onto the quick-release fitting.

This completes the process of making a homemade car for a car with your own hands.

Seat reupholstery

Homemade products can also be useful for updating the interior. Useful gadgets and crafts for cars allow you to replace worn out parts, add lighting to the interior and do much more. Let's consider the option of updating the seats.

For this you will need fabric. You can choose two colors - beige leather will be suitable for the central part of the seats, the back of the backrest (about 4 m of it will be needed), and everything else will be black. Black leather needs about 3.5 m. All fabric needs to be duplicated (glued) with a layer of foam rubber 0.5 cm. The foam rubber is glued with non-woven material using an iron. This will make it easier to work with.

Co removed seats(it’s more convenient) remove the covers. We number their individual parts. In order not to get confused, we transfer everything to paper. Also on paper you need to mark the places where the knitting needles are attached (they are on the back of the covers). The knitting needles themselves will then be inserted into new cases.

Next, we disassemble the casing into individual parts (unravel the seams). Patterns are obtained necessary elements. We lay them out on the wrong side of the fabric (wrong side up to avoid mirroring the details) on thick paper (you can use wallpaper) and trace them around the perimeter. We leave a 1 cm allowance along the edges, which will be used for seams. Then all the patterns are cut and sewn (starting from the center). On the reverse side of any fabric we make pockets into which the knitting needles are inserted.

Having connected all the parts, we get new covers. We carry out this process one by one for all seats. Having made such interesting and useful homemade products for your car with your own hands, you can update the interior without contacting a service center.

Ceiling renovation

You can also replace the ceiling trim yourself. In this case, homemade products for a car must begin by removing the ceiling. This can take quite a long time. Fastening is individual in each case. There is nothing complicated, the main thing is to carefully inspect everything and check that all the parts remain intact.

When the ceiling panel is removed, the old fabric is removed from it. When preparing material for the ceiling, you need to remember one thing important point: on the wrong side it should have a small layer of foam rubber. The fabric is glued with heat-resistant glue. When the glue has dried, the panel can be reinstalled on the ceiling. Do this in reverse order.

"Angel Eyes"

It is quite possible to assemble useful electronic homemade products for cars with your own hands. For example, “angel eyes” will allow you to update the headlights of any car. To make them you will need:

• plastic transparent sticks (can be from blinds);
• resistors (220 Ohm);
• battery (9 V);
• LEDs (3.5 V).

The process looks like this:

1. On any metal can, the same diameter as the headlights, we screw a ring from a plastic stick using pliers. To do this, it is heated a little.
2. Next, connect a pair of LED and resistor. Their performance is checked using a battery.
3. Another LED is connected to it.
4. We make deep cuts on the frozen ring from a plastic stick.
5. We assemble the ring, attach the LEDs, and connect.

Conclusion

Anyone can assemble homemade products for a car with their own hands. The main thing is to be confident in your abilities. A little information from our article, a little of your reasoning and thoughts, and everything will work out. And the car will only get better from this. And it’s doubly nice that it was done with your own hands.
