Correct setting Ignition timing (IAP) is one of the main aspects of adjustment that allows you to achieve proper operation engine. Due to an incorrectly set OZ, the engine will work intermittently, and in some cases it will not start at all. You can use a strobe light to make adjustments. How to build a strobe light for installing the ignition with your own hands - learn from this material.

Description of the strobe

How to make a simple strobe for setting up an OZ on LEDs, what elements will the circuit of the device consist of? First, let's look at the main characteristics of the device.

Working diagram

The main constituent elements using the example of the above diagram:

1. The power circuit consists of switch SA1, diode element VD1 and capacitor device C2. The diode is used to protect other components from erroneous polarity reversal. The capacitor itself is used to block possible interference, thus preventing failure of the trigger. The purpose of switch SA1 is to activate and deactivate power.
2. An equally important component is the input circuit, which includes the controller, resistor elements R1 and R2 and capacitor device C1. The role of the controller here is played by the device clamp, which is called a crocodile, it is fixed on the first cylinder. If the connection is correct, then the above elements form a simple differential circuit.
3. Trigger circuit. This component consists of two single vibrators used to generate a signal of the desired frequency at the output. These components perform the function of frequency setting.
4. The output stage is made using resistor elements R5-R9, and transistors VT1 are also used for this purpose. VT2 and VT3. These devices are necessary to increase the output current of the trigger board. The resistor device R5 sets a certain base current of the transistor element number 1 (the video was shot by Maxim Sokolov).

Operating principle

The device for setting the advance angle is powered by a built-in battery or car battery. When the switch is activated, the trigger starts working first. At outputs 2 and 12 of the board, an increased potential is formed, and a low potential is formed at pins 1 and 13. At this moment, capacitor parts C3 and C4 receive power from resistors.

The signal from the controller goes through a differential circuit and is ultimately supplied to the DD1.1 input. Since it is a one-shot device, it results in switching of the device. Then C1 is overdischarged in the circuit, which again contributes to switching the trigger.

Element DD1.1 will respond to pulses supplied from the controller, thus generating new rectangular pulses at the first pin. In the case of the second one-shot DD1.2, the principle of operation will be identical - thanks to this device, the pulse duration at pin 13 is reduced by 10 times. This element operates under a load supplied from the amplifier stage of transistors, which open for the duration of the pulse. Thanks to the resistor components R6, R7 and R8, the current is limited, its value in total should not exceed 0.8 amperes.

The current value is not high, this is due to the following factors:

• the pulse duration is no more than 1 second;
• Usually, car owners need no more than 10 minutes to set up the OZ; during this time the crystals will not overheat;
• diodes used today have improved performance and features when compared to devices used more than 10 years ago.

Printed circuit board and assembly parts

In order to build a strobe light with your own hands, you will need a board with all the necessary elements.

As an example:

1. On the board we are considering, the diode function is performed by the KD2999V controller. In principle, you can use any other one, you just need to take into account that the diode element must have a minimum voltage drop.
2. Capacitors are also used. It is important that they are rated at 0.068 µF. As for the main capacitor device C1, it is a high-voltage part, the voltage on which is 400 V.
3. The trigger device - TM2 - has excellent resistance to possible interference.
4. It is necessary that the transistors used VT1, as well as VT2, have a high gain.
5. As for the diodes marked with the symbols HL1-HL9, they should have maximum brightness, and it is also desirable that the dispersion angle be small. Diode components are mounted on a separate circuit; their number should be 3 in a row.

Device setup nuances

Before using a homemade strobe light on a car, it must be configured correctly. Initially, you should adjust the trimming resistor component, this will make it possible to provide the desired visual effect. As you move the slider, you can see that due to the drop in pulse, the illumination of the marks will be ineffective, and if the pulse is too high, the lighting will be washed out. On at this stage you need to properly adjust the effectiveness of the light flashes (video shot by Serj ZP).

Installation of UOZ with a strobe light

How to use a homemade device to adjust the OZ:

1. First you need to start the engine and warm it up to operating temperature. To do this, let the unit run at idle speed.
2. Then you will need to connect your homemade device to a power source. This can be either a built-in battery or a car battery.
3. Next, a copper sensor should be connected to the core of cylinder 1; to do this, wind it around the core.
4. After this, the diode light bulb should be aimed at the mark marked on the housing of the distribution mechanism.
5. When these steps are completed, you need to find a fixed point, it is located on the flywheel pulley.
6. In order to ensure that these points coincide, you need to rotate the switchgear housing. And when the points coincide, the body must be fixed in this position. When the points match, the diodes should light up.

How to make a device yourself?

Today there are many various options circuits for making a strobe light. We recommend that you familiarize yourself with one of the simplest and least costly manufacturing methods.

To implement it you will need the following components:

• transistor device KT315;
• thyristor element KU112A, as well as resistor components rated at 0.125 W;
• diode light bulbs or a flashlight with LEDs, which will be used as a housing, and the number of diode elements must be at least 6 pieces;
• capacitor devices C1;
• V2 in the diagram is the low frequency diode component;
• you will also need a relay, its index should be RWH-SH-112D;
• power cable, its length must be at least one meter;
• clamps;
• you will also need a piece copper wire approximately 10 cm long.

All these components can be purchased at any themed store or radio market.

How to build such a device yourself:

1. To begin with, you should drill a hole on the back side of the prepared case, through which you will lay the power cable.
2. Then the prepared clamps must be soldered to the ends of the prepared cords. It is advisable to mark on them in advance which will be positive and which will be negative; it will be better if the colors of the clamps are different.
3. The sensor itself is mounted on the left or right side of the housing. One more hole needs to be made on the side of the case; it will be used to lay the cord to contact X1.
4. Then a prepared piece of copper wire should be soldered to the main cable core. This wire is considered one of the main ones, since it will be used as a device sensor.
5. All that remains is to insulate the connections with electrical tape or heat pipes.

Conclusion

As you can see, in general, building such a device is not a problem. It is enough to have some knowledge in the field of electronics and follow the steps described in the instructions. If you make mistakes during assembly, the device may not work correctly. If you do not have experience in making such devices, then it may make sense to think about buying a new strobe light.

The quality of engine tuning is a decisive factor on which not only the duration of operation, but also power and fuel consumption depend. In addition, not a single engine used as fuel - gasoline - can operate without a special system - the ignition system. It is this that allows the air-fuel mixture to ignite and detonate inside the engine, causing the crankshaft to rotate and the vehicle to move.

The ignition system ensures the formation of a spark to ignite the mixture in the required cylinder strictly at the moment of compression. This happens in a certain sequence of cylinder operation.

The fuel-air mixture must ignite at a certain point in time. To do this, the spark fires at a certain moment in strict coordination with the optimal operating condition of the engine with the ignition timing. These conditions are determined primarily by the number of revolutions of the running engine, as well as the load at which it operates.

Thanks to a well-tuned ignition system, the required amount of energy is supplied to form a spark, which allows you to reliably ignite the working air-fuel mixture. It is the quality and reliability of the car’s ignition system that represent optimal conditions to ensure continuous spark formation in the system.

However, it may happen that a malfunction occurs in the ignition system both during engine start and during subsequent operation. This may manifest itself in several factors, such as:

• poor engine start, or inability to start it;
• engine tripping during operation, as well as involuntary stopping when sparks leak in the working cylinders;
• incorrect ignition timing leads to detonation of the air-fuel mixture and, as a result, accelerated wear of engine working parts;
• During malfunction of the ignition system, electromagnetic interference appears, which can affect the operation of some electronic systems.

Thanks to timely diagnostics, engine performance can be eliminated. large number possible problems. To correctly determine the angle and timing of ignition, special equipment called a strobe is used. Today, such a necessary device can be purchased at any car store, or you can make it yourself. The latter method can be no less reliable, but at the same time be less expensive.

Strobe, operating principle of factory stroboscopes

Many people know that most problems that may arise during the operation of a car can be easily eliminated independently using self-diagnosis, as well as certain skills and knowledge of the design of such equipment. Even despite the complexity of the car, you can easily deal with problems that arise on your own, without the need to go to a service station.

Almost every car owner wants to save some amount of money when purchasing a factory strobe light for setting the ignition on the car. Very often, car owners make such a device themselves, but if they lack confidence in their own abilities, they can easily purchase a high-quality branded strobe light at the nearest car store.

Until the car owner decides to purchase a branded strobe light, it is necessary to carefully study its main features, as well as its operating principle. To do this, first of all, you need to decide on the scope of application of this automotive device. This device, which is called a strobe, allows the car owner to adjust and tune the car’s ignition without much difficulty. Such a device allows you to significantly speed up this process, without requiring excessive time to create your own homemade device.

The design of this device provides for the presence of a special warning lamp, thanks to which you can immediately determine the correct moment of spark appearance and set the ignition timing. The main advantage of a branded strobe light is not only the efficiency of detection, but also the accuracy of performing such tasks in a matter of minutes.

However, along with such a significant advantage, there is one big drawback of such a device. The high cost of this device leads to the fact that most car owners are trying to make a similar device on their own, without the need to spend a significantly larger amount on purchasing a branded strobe light. The high cost is due to the fact that almost all factory models have expensive gas-discharge lamps in their design, when replacing which it will be much easier to purchase a new device. Price gas discharge lamps comparable to the price of a new device.

Do-it-yourself strobe - saving material resources

If the car owner has the time and desire to save a significant amount of money, then such a strobe light can easily be made independently. For these purposes, you will need to purchase certain parts, most of which are already in the garage of most car owners.

A simple design of a car strobe light can be created from an ordinary flashlight, simple and low-power LEDs, and even such children's fun as a laser pointer. Despite the simplicity of the design and somewhat original appearance, such a device, made with your own hands, will last as long as a branded strobe.

Such a device for adjusting the car’s ignition system is most necessary for those cars that have a carburetor. The use of a strobe light in such cars is due to the fact that the ignition is adjusted in a special way. Adjusting the ignition timing, which is located on the contact group of the distributor and virtually all distributors that do not have contacts, is very difficult and is absolutely impossible to do without a special device. Thanks to a self-made strobe, you can adjust the ignition timing with maximum accuracy in just 10 minutes.

Adjusting your vehicle's ignition system is extremely important. Thanks to this, the operation of many vehicle systems will be more harmonious and the vehicle will be able to operate at a high level. Since the cost of a branded strobe light in car stores is significantly high, this became the decisive factor for creating an independent strobe model.

Do-it-yourself strobe at minimal cost, strobe diagram based on a flashlight or camera body

There is nothing better for any car owner to perform high-quality diagnostics or minor car repairs, while managing to save a significant amount. The money saved can be used to improve your car, or to buy something nice for yourself and your loved ones. It is a self-made invention that allows you to reduce the financial costs of car repairs and maintenance. To set the ignition timing, a diagram of several variants of a homemade strobe light was proposed.

A stroboscope is an excellent auxiliary tool that allows you to fine-tune the engine ignition system of any modern car that uses a carburetor. The device itself for installing the ignition can be easily made independently from any available materials, which will be several times cheaper than buying an expensive strobe light. For example, today car dealerships provide a wide selection of stroboscopes, the cost of which varies from 1,000 to 6,000 rubles.

The most common type of homemade stroboscopes, which require minimal costs for parts, can be assembled based on the body of a flashlight or camera. The cost of such a device will be several times cheaper and in most cases will not exceed 600 rubles, but in practice it will be just as reliable, efficient and durable.

Today there are already a large number of schemes by which you can easily assemble a high-quality and working strobe. In order to make it yourself you will need a little skill in working with a soldering iron, a little time and perseverance. The most popular scheme can be chosen as follows, consisting of the following parts:

• power cord - 1 m;
• transistor KT-315;
• thyristor KU-112A;
• several 0.125 W resistors;
• capacitors C1;
• LF diode V2;
• relay with index RWH-SH-112D;
• several special clamps;
• copper wire - approximately 10 cm.

For many radio amateurs, this simple set of elements can be found in the garage, and if they are not available, there are stores of similar electronics or an amateur radio market in any city. This is a standard set of radio components for creating such a simple diagnostic tool.

The housing for the design of this homemade strobe light will be an unnecessary but working flashlight, or a broken point-and-shoot camera. You can choose it at your discretion from what may be at hand and no longer needed in the household.

In order to make a strobe, you need to make a small hole in the back wall of the flashlight or camera, through which you pass the power wire. After that, special alligator clips should be soldered or otherwise secured to the ends of the wires. For greater convenience, you need to install “crocodiles” different colors, or mark the wires with multi-colored adhesive tape. This will allow you to indicate the “plus” and “minus” of the power supply.

In order to install the sensor, you need to decide on which side it will be fixed, then make a small hole on the desired side and insert the wire into it to the sensor contact. Next, you need to solder a previously prepared small piece of copper wire to the main core of the wire. It is this that will serve as the main strobe sensor. All connections should be carefully insulated from the possibility of short circuits.

Such a simple device, made from scrap materials, can be multifunctional. It can be used as an ignition control device, to check the functionality of spark plugs, and also to adjust the regulator.

DIY strobe light based on a timer (diagram)

A strobe for setting the optimal ignition angle can easily be assembled on the basis of a tool such as a timer. Despite its significantly expanded circuit, it has a very major advantage - the timer has an even light pulse that will in no way depend on the voltage of the supply battery. A measuring device assembled on the basis of a timer can work as an engine speed meter. In order to switch it, it will be enough to turn a special regulator.

It is not possible to assemble such a circuit of a high-quality and working strobe light so quickly. However, a number of significant advantages will not take long to arrive. As a substitute for a special sensor, you can wind about 5 turns of wire around the spark plug.

DIY strobe light based on LEDs (diagram)

Today, LEDs are the most common type of lighting fixture. They achieved such popularity for a number of advantages that other lighting devices cannot compete with. The first advantage was cost-effectiveness. This positive property was achieved due to lower power consumption, while their brightness is at a very good level. In addition, the operating time of the average LED reaches 50,000 hours of continuous operation, which in turn has become another advantage of using this type of lighting in all areas of human activity.

The use of LEDs for the manufacture of a strobe light has not been spared. The availability of this part allows them to be used on a large scale, and the low power consumption has contributed to the fact that a brighter and more noticeable strobe can be made. This device can be easily used in the brightest daylight.

The circuit of this device uses a special 155AG1 microcircuit, triggered by pulses with negative polarity. In the circuit itself, 3 resistors were used, which influence and “cut” the amplitude of the input signal. And the further duration of the pulse signal is set using capacitive capacitor C4, as well as resistor R6. The power source for such a circuit must be connected to the vehicle’s on-board electrical network.

Pro Tip: How to Set Up Manufactured Strobes

Self-assembled strobes will essentially be no different from branded strobes purchased in car stores. Professionals recommend taking into account some nuances when diagnosing a car and the ignition system in particular.

1. The engine of the vehicle being tested must be started and idling without gas leaks, etc.
2. To a self-made strobe, you need to connect an external power supply, which can be a car battery, or another battery.
3. A copper sensor must be wrapped around the core of the engine cylinder.
4. The light should be directed at the mark located on the distributor body.
5. The next step is to find a point on the flywheel pulley.
6. The distributor body should be rotated until the two points come together, after which they should be fixed in a certain position.

How to find and order a strobe light on Aliexpress at a reasonable price and free shipping

An LED strobe light for installing the ignition allows you to quickly and accurately set the optimal ignition timing (IAP) in the car. This parameter plays important role in the correct operation of the engine. A slight displacement at the moment of ignition leads to a loss of power due to increased fuel consumption and engine overheating.

Despite the large assortment of industrially produced devices for checking and installing SPDs, the relevance of creating a strobe light with your own hands has not lost its meaning in our days. The presented diagram of a homemade strobe light for a car does not require adjustment after assembly and is made from available parts.

Schematic diagram of a strobe

The scheme was developed and presented in the ninth edition of Radio magazine back in 2000. However, due to its simplicity and reliability, it remains relevant today.

In the circuit diagram of a strobe light for a car, 4 parts can be divided into four parts:

1. Power circuit consisting of switch SA1, diode VD1 and capacitor C2. VD1 protects circuit elements from erroneous polarity reversal. C2 blocks frequency interference, preventing trigger malfunctions. Switch SA1 is used to supply and disconnect power; any compact switch or toggle switch is suitable for this.
2. The input circuit, which consists of a sensor, capacitor C1 and resistors R1, R2. The sensor function is performed by an alligator clip, which is attached to the high-voltage wire of the first cylinder. Elements C1, R1, R2 represent the simplest differentiating chain.
3. A trigger microcircuit assembled according to a circuit of two monovibrators of the same type, which generate pulses of a given frequency at the output. The frequency-setting elements are resistors R3, R4 and capacitors C3, C4.
4. The output stage is assembled using transistors VT1-VT3 and resistors R5-R9. Transistors amplify the output current of the trigger, which is reflected in the form of bright flashes of LEDs. R5 sets the base current of the first transistor, and R9 eliminates malfunctions in the powerful VT3. R6-R8 limit the load current flowing through the LEDs.

Operating principle

The strobe circuit is powered by a car battery. At the moment the switch SA1 is closed, the trigger DD1 goes to its original state. In this case, a high potential appears at the inverse outputs (2, 12), and a low potential appears at the direct outputs (1, 13). Capacitors C3, C4 are charged through the corresponding resistors.

The pulse from the sensor, having passed through the differentiating circuit, arrives at the clock input of the first monovibrator DD1.1, which leads to its switching. Recharging of C3 begins, which after 15 ms ends with the next trigger switching. Thus, the one-shot device reacts to pulses from the sensor, generating rectangular pulses at the output (1). The duration of the output pulses from DD1.1 is determined by the ratings of R3 and C3.

The second one-shot DD1.2 works similarly to the first, reducing the duration of the pulses at the output (13) by 10 times (to approximately 1.5 ms). The load for DD1.2 is an amplifier cascade of transistors that open for the duration of the pulse. The pulse current through the LEDs is limited exclusively by resistors R6-R8 and in this case reaches a value of 0.8 A.

Don't be so scared of great importance current Firstly, its pulse does not exceed 1 ms, with a duty cycle in operating mode of at least 15. Secondly, modern LEDs have much better technical characteristics compared to their predecessors from 2000, when this scheme first came into practical use. Then it was necessary to look for LEDs with a luminous intensity of 2000 mcd. Now a white LED (from the English Light-emitting diode) type C512A-5 mm from the company with a dispersion angle of 25° is capable of delivering 18,000 mcd at DC at 20 mA. Therefore, the use of ultra-bright LEDs will significantly reduce the load current by increasing the resistance R6-R8. Thirdly, the time of using a strobe usually does not exceed 5-10 minutes, which does not cause overheating of the emitting diode crystals.

Printed circuit board and assembly parts

A homemade strobe light for installing the ignition can be assembled using both inexpensive domestic radio elements and more precise imported elements. Below is a board using domestic components for pin mounting.

Board in Sprint Layout 6.0 file: plata.lay6

Diode VD1 - KD2999V or any other with a low forward voltage drop. Capacitor C1 must be high-voltage with a capacity of 47 pF and a voltage of 400 V. Capacitors C2-C4 are non-polar KM-5, K73-9 series at 0.068 μF 16 V. All resistors, except R4, are MLT type or planar with the values ​​indicated in the diagram . Trimmer resistor R4 type SP-3 or SP-5 at 33 kOhm.

It is better to use a TM2 trigger of the 561 series, which is characterized by high noise immunity and reliability. But you can replace it with a 176 and 564 series microcircuit, taking into account their pinout. Transistors VT1-VT2 are suitable for KT315 B, V, G or KT3102 with a high gain. Output transistor – KT815, KT817 with any letter prefix. It is better to take super-bright LEDs HL1-HL9 with a small dispersion angle. They are placed on a separate board, three in a row. If any circuit parts are missing, they can be replaced with more modern analogues, slightly improving the board.

The finished strobe control board and the board with LEDs can be conveniently placed in the body of a portable flashlight. In this case, it is necessary to provide a hole in the housing for the R4 regulator, and a standard switch can be used as SA1.

Settings

The circuit contains a tuning resistor R4, by adjusting which you can achieve the desired visual effect. By rotating the knob, you can observe that a decrease in the current pulse leads to a lack of illumination of the marks, and an increase leads to blur. Therefore, during the first launch of the strobe, it is necessary to select the optimal duration of the flashes.

The length of the shielded wire from the printed circuit board to the sensor should not exceed 0.5 m. A 0.1 m copper conductor soldered to the central core of the shielded wire is suitable as a sensor. At the moment of connection, it is wound onto the insulation of the high-voltage wire of the first cylinder of the car, making 3 turns. To increase noise immunity, winding is carried out as close to the spark plug as possible. Instead of a copper conductor, you can take an alligator clip, which should also be soldered to the central core, and its teeth slightly bent inward so as not to damage the insulation.

Installation of UOZ with a strobe light

Before considering the operation of a car strobe light, you need to understand the essence of the stroboscopic effect. If an object moving in the dark is illuminated for a moment with a flash, it will appear frozen in the place where the flash occurred. If you put a bright mark on a rotating wheel and illuminate it with bright flashes that match the frequency of rotation of the wheel, then at the moment of the flashes you can visually record the location of the mark.

Before adjusting the ignition timing of a car, two marks are applied: a movable one on the crankshaft (flywheel) and a stationary one on the engine body. Then the sensor is connected, power is supplied to the strobe and the engine is turned on in idle mode. If the marks coincide during flashes, then the OZ is set optimally. Otherwise, adjustments should be made until they completely match.

The presented strobe light for installing the ignition, assembled with your own hands, will allow you to debug the car’s ignition system in a few minutes. As a result of the adjustment, the engine efficiency will increase and its service life will increase.

The correct operation of a car engine depends on how the ignition is set. This is due to the fact that the combustible mixture entering the combustion chamber must be completely ignited. To install the ignition, a strobe light is used, which you can make yourself or purchase at a specialized store. We will discuss below how easy it is to make a strobe light for installing the ignition with your own hands.

The purpose of the strobe, the parts that will be needed for its manufacture

The strobe light for installing the ignition is used so that the car enthusiast can adjust the correctness and timeliness of the supply of electric current, which forms a spark. It serves to ignite the incendiary mixture in the combustion chamber of the cylinders of gasoline power units.

The correct operation of the motor and its power depend on the timeliness of its supply. Therefore, correctly set ignition is necessary for the power unit to work well.

In specialized stores, this device costs from 1,000 to 7,000 rubles. Therefore, in order to save money, it is better to make a homemade strobe light to install the ignition with your own hands. To assemble it (I did it myself), you will need to spend up to 500 rubles.

In general, a strobe is the simplest scheme and design. It is based on the principle of the effect of a spark on the ice of a light bulb, which can be taken from any flashlight. Thus, it is easy to set the ignition angle, which will ideally meet the requirements for timely and complete ignition of the fuel mixture.

Let's look at the list of parts that you will need to easily make your own strobe light:

• transistor marked KT 315;
• thyristor, which is marked KU 112 A;
• copper wires;
• flashlight with diode bulbs (there should be at least 6 of them, more possible);
• timer, used for some homemade strobes;
• low-frequency diode marked V 2;
• resistors, with a power of 0.125 W;
• relay, which has the index RWH/SH-112D;
• 1 meter long cord to power the device;
• base for collecting the microcircuit, made of insulating special material;
• special terminals (clamps).

Here are the components you will need to install the strobe light yourself. They can be purchased in special stores or at radio markets.

The circuit of the simplest strobe looks like this:

It is important to remember that to make this device it is best to take the body of a simple diode flashlight, or from a flashlight. All the parts will fit there, including the microcircuit on which the parts will be located.

Strobe assembly

The assembly process takes place at home using a soldering iron, using the following algorithm (the body of the flashlight is taken as the basis):

• drilling a hole on the back wall of the flashlight body, this is necessary in order to route the power cord;
• soldered to the ends of the cord special terminals, the main thing is not to confuse the polarity (they are taken in different colors);
• sensor placement on the right or left side of the body;
• drilling a hole, it is done at the location of the sensor, a cord is inserted into it (a cord is laid), which is connected to contact X 1, indicated in the diagram;
• assembling a microcircuit, this is done according to the above scheme, using a soldering iron (if the car enthusiast is not good at assembling such circuits, then he needs to contact a specialist in this field);
• soldering copper wire to the main core of the wire, it will serve as a special strobe sensor;
• insulation of all connections special tape.

Here's how to make a strobe light with your hands with the lowest financial costs.

It is important to remember that such a device can be used not only for setting the ignition, but also for checking spark plugs and adjusting the regulator. That's how many useful functions it can perform for a car enthusiast.

Types of homemade stroboscopes

Above is a diagram and algorithm for creating a simple strobe light. Some craftsmen also recommend making such devices based on a timer or LEDs.

Let's look at the strobe circuit, which includes a timer:

This design is more complex, so if a car enthusiast thinks that he cannot assemble it on his own, it is better to contact a specialist and purchase all the necessary parts. If there is no domestically produced timer, it can be replaced with a foreign one, which must be marked NE 555. And it is better to use diodes for such a circuit with the designation KD 521.

It is interesting to know that having made such a device with a timer, you can install a regulator on it, by switching which it will begin to work like a tachometer. At the same time, even a weak battery charge will not affect its operation.

Now let's look at a circuit that allows you to make a strobe using LEDs. It should be noted right away that they are characterized by increased reliability; it can be used even in bright daylight.

The diagram of such a strobe is as follows:

The entire circuit will be based on a microcircuit marked 155 AG 1, which can be triggered by pulses that have negative polarity. Resistances suitable for it are R 1, R 2, R 3, resistor R 6. Resistances limit the amplitude of the incoming signal, and capacitance C 4 regulates the duration of the signal coming from the motor.

Setting up the strobe

After this device is manufactured, it needs to be configured. It happens this way:

• the engine is warming up, it needs to be started, warmed up, and then switched to idle mode;
• The strobe is connected by terminals to the battery;
• a copper wire (sensor) is wound around the core of the cylinder;
• the light that will be created is directed to a special point marked on the body;
• find a fixed plane (point) on the motor flywheel;
• Rotate the body of the ignition element so that the two points coincide, and then fix it in this place.

After these manipulations, the device is ready to perform its functions. The main thing is not to violate this installation order.

You can make a strobe light for setting the ignition yourself by purchasing the necessary parts. After that, it is customized and will serve the car enthusiast no worse than those sold in stores. In addition to setting the ignition, such devices, made using a timer or LED lights, can perform other useful functions.

Stroboscopes are used on cars to adjust the ignition system of the power unit. This device can be purchased at any auto store. But you can make the device yourself. Process self-made The strobe light doesn't take much time. More on this later in the article.

A strobe light makes life much easier for its owner.

Thanks to it, even an inexperienced motorist can independently adjust the ignition angle. The operation of a strobe is based on the stroboscopic effect - a moving object is illuminated by a light flash.

Having such a device is beneficial, as it makes it possible to independently regulate the ignition without contacting a service center, which saves the car owner time and money. There are car enthusiasts who prefer factory strobes, not trusting homemade ones, but they are no worse than traditional store-bought ones.

Why is it difficult to set the ignition without a strobe?

It is very difficult to adjust the ignition system with your bare hands. The stroboscope allows you to speed up the ignition adjustment time several times vehicle. The light in the lamp of this device signals the formation of a spark, which makes it possible to adjust the correct advance angle.

Factory-made strobe, pros and cons

Factory devices work flawlessly and efficiently, but they cost a lot. But in fact, all such devices have an expensive lamp, the failure of which leads to the purchase of a new device. It is worth noting that even at service stations, some craftsmen use homemade devices.

Top 5 most popular factory strobes

The most popular factory-made stroboscopes:

The cost of such devices reaches six thousand rubles. If you make a strobe light yourself, it will cost you about 600-700 rubles. Thus, saving money actually stimulates making such a device with your own hands tenfold.

Such parts and spare parts can be purchased at any electronics store or radio market. The device body is small in size. You can even use the base of an old flashlight.

Strobe circuit

There are a lot of diagrams on the Internet on how to create a simple strobe light yourself. Most of them are easy and quick to assemble, without requiring significant financial investments.

Assembling a strobe light with your own hands, step by step, the easiest option

Sequence of actions:

• Drill a hole for the power cable.
• Observing polarity, solder the clamps to the ends of the wires.
• The sensor can be installed on the right or left.
• We solder copper wire to the main core.
• We isolate all contacts.

This invention is used to test the operation of the regulator and spark plug.

Timer-based strobe, pros and cons

To make a device yourself using a timer, you need to put in more effort than for a regular strobe. The key advantage of such a device is constant light pulses that do not depend on the battery voltage. A strobe light is used similar to a tachometer. To do this you need to switch the regulator.

LED strobe, pros and cons

The basis of such devices is the 155AG1 microcircuit, which requires pulses with negative polarity to start. In such circuits it is necessary to use resistances R1, R2, R3. They limit fluctuations in the input signal. This circuit will be powered by a battery. The duration of the pulses can be provided by capacitance C4 with resistor R6. According to classic settings, this value will be 2 ms.

How to use homemade strobes

For the homemade device to function correctly, it must be checked. From the existing device you need to set the advance angle:

1. First, we warm up the power unit and leave it to idle.
2. We connect the device to the battery.
3. We wind the copper sensor onto the cylinder core.
4. Next, you should orient the light source according to the special indicator on the body.
5. We look for a fixed point on the flywheel.
6. To make the two points coincide, rotate the ignition housing and keep it in the desired position.

The key point when making this device yourself is correct assembly. electrical diagram. That is why, before starting production, it is imperative to first make detailed diagram, which will help to avoid errors when assembling the device.

Don't forget about safety precautions. Any strobe operates under voltage. Do not allow the internal elements of the device to touch its body, especially the metal one.

It is advisable that the variable resistor be protected with a plastic handle. A well-insulated power cord must have a plug. All parts must be mounted on a special board made of insulating material. The parts are mounted according to a special scheme, but their location is not important. It is necessary to attach all elements very carefully.
