Stroboscope for setting the ignition angle. How to set the ignition with a strobe? Schematic diagram of a stroboscope

Stroboscopes are used on cars to install the engine's ignition system. Such devices are sold in any auto shop. However, the device can be made by hand. The process of making a stroboscope will not take much time.

Simple stroboscope

A stroboscope makes life much easier for its owner. With it, it will independently adjust the ignition angle. The device works due to the stroboscopic effect - a moving object is illuminated by a flash of light.

It is beneficial to have this device, since it will allow you to adjust it yourself, without contacting service centers. And this will save money and time of the car owner. Some people do not trust homemade strobe lights, but they are just as good as store bought ones.

Do-it-yourself strobe light for ignition installation

With "bare hands" it is difficult to adjust the ignition system. The stroboscope at times speeds up the time of setting the ignition of the car. The light in the strobe lamp signals that a spark has appeared, and this allows you to set the correct advance angle in the ignition system.

Factory appliances work efficiently and flawlessly, but they cost decently. Almost all such devices have an expensive lamp. If it fails, in fact, you will have to buy a new device. Meanwhile, even at service stations, some craftsmen use homemade devices.

The most popular factory strobe lights:

• multitronics C2
• focusF1
• focusF10
• astrol5

The price of such devices reaches 6000 rubles. When making a stroboscope with your own hands, it will cost you - 600-700 rubles. Saving money by almost 10 times encourages you to make such a device yourself.

How to make a stroboscope for setting the ignition

There are many schemes on the Internet on how to create a simple do-it-yourself strobe light. Most of them are quickly and easily assembled without requiring large financial investments. One of the most used schemes for creating a stroboscope on your own requires the following elements:

• copper wires;
• diode flashlight;
• capacitors c1;
• low frequency diode V2;
• specialized clamps;
• thyristor KU112A;
• resistors 0.125 W;
• meter power cord;
• relay with index RWH-SH-112D.

Such elements are sold at any radio market or electronics store. The body of the device is small. You can use the base of an old flashlight.

Sequencing:

1. It is necessary to drill a hole for the power wire;
2. Solder the clamps to the ends of the wires, observing the polarity;
3. The sensor itself can be installed on the left or right;
4. Copper wire must be soldered to the main core;
5. All contacts must be isolated.

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

Automotive stroboscope and LED manufacturing scheme

The 155AG1 chip is considered the basis in such devices. To start it, pulses with negative polarity are needed. In such circuits, it is necessary to use resistances R3, R2, R1. They give limits on the fluctuations of the input signal. The duration of the pulses is provided by the capacitance C4 together with the resistor R6. By default, this value will be 2 ms. This scheme will be powered by.

Strobe using a timer

To make a device yourself using a timer, you need to make more efforts than for a simple strobe. The main advantage of such a device is constant light pulses that do not depend on the battery voltage. A stroboscope such as a tachometer is used. To do this, you need to switch the regulator.

Device settings

For the correct operation of a homemade device, it must be checked. From the existing device, it is necessary to set the lead angle.

For this you need:

• warm up the engine and leave it on;
• connect the device to the battery;
• wind the copper sensor around the core of the cylinder;
• orient the light source according to the special designation on the body;
• find a fixed point on the flywheel;
• to match the two points, it is necessary to rotate the ignition housing and keep it in a certain position.

The main point in the independent manufacture of a stroboscope is the correct assembly of the electrical circuit. Therefore, before starting manufacturing, it is recommended that you first make a detailed diagram. It will help to avoid errors during the assembly of the device.

Don't forget about safety. The stroboscope works under voltage. Do not allow the internal parts of the device to touch its body, especially metal.

It is good if the variable resistor is protected by a plastic handle. A well-insulated power cord must have a plug. All parts must be installed on a special board made of insulating material. The location of all the parts is not important, but it is necessary to mount them following a special scheme. Fastening all the details is required very carefully.

Reminder about the stroboscope

If difficulties arise in the manufacture of the device, it is best to contact a knowledgeable person. As an alternative to a "live" assistant - a detailed video tutorial describing the manufacturing process and operation of the stroboscope:

Stroboscope for ignition installation: how to use the diagram

With a stroboscope, setting the ignition on a carburetor engine is always much more convenient than “by ear”. But the price tags for such equipment sometimes “bite”, which pushes many motorists to alternative solutions to this issue, for example, by making a stroboscope with their own hands.

The average price of a factory product and its disadvantages

The factory version of the device has some drawbacks that significantly reduce the usefulness of such an acquisition.

It is always more convenient to set the ignition on carburetors with a strobe

Firstly, the cost of factory strobe lights is quite a lot. So the digital model Multitronics C2 will cost the buyer about 900-1000 rubles. A more functional AstroL5 stroboscope will already cost 1300 rubles. Focus F1 - a model suitable for servicing both gasoline and diesel engines - will require 1700 rubles. its more "advanced" fellow Focus F10 - 5600 rubles.

Secondly, manufacturers often use an expensive gas discharge lamp in the design of their products. It has a limited resource and may require replacement after a short time, which will not only hit your pocket, but will be tantamount to buying a new stroboscope.

How much will a homemade stroboscope cost to adjust the ignition

Based on the above disadvantages of a store strobe. it seems appropriate to conclude that it is expedient to manufacture such equipment at home. Moreover, it is much more convenient and cheaper to equip it with affordable LEDs, which cost mere pennies. For such purposes, as a donor, a cheap laser pointer, flashlight, etc. is quite suitable.

In the same way, there will be no problems with other components, as well as tools. The total budget of the venture should not be more than 100-150 rubles.

How to make a stroboscope with your own hands

There can be many options for the execution of a "home" stroboscope. However, in general, all such projects are structurally similar. Consider the principle of assembling this gadget in the following example.

• transistor KT315 (you can find it in any radio equipment of the past era, it can have different letter indices);
• thyristor KU112A (easy to find in the switching power supply of ancient TVs);
• small-sized resistors with a power of 0.125 W;
• cheap (Chinese) flashlight on diodes (the number of diodes can be different, but better - from 6 to 10 pieces);
• capacitor C1 energized from 16 volts;
• diode V2 - any low-frequency, for example KD105 or D9;
• small-sized relay (index BS-115-12A-DC12V or RWH-SH-112D, 12 Amps, coil - 12 Volts); however, domestic relays can also be used, for example, of the RES-10 type, with a coil voltage of 12 Volts;
• power wires of the required length (about 0.5-0.6 m) and crocodile clips for connecting the stroboscope to the battery;
• shielded wire up to 0.5 m, a piece of copper wire about 10 cm.

How to connect everything, strobe circuit

Strobe connection diagram

It is convenient to place all the main parts of the device right in the body of a flashlight or a conventional camera flash. At the same time, power wires pass through the rear hole of the flashlight (flashlights), at the ends they have soldered crocodile terminals of different colors or with markings (so as not to confuse “plus” and “minus”). A hole is drilled in the side wall of the housing (if it is not available) for laying a shielded wire through it to contact X1. The braid of this cable at the end must be insulated, a piece of copper wire about 0.1 m long must be soldered to the main core - this is a stroboscope sensor.

The operation of the stroboscope for setting the ignition from a flash or flashlight

According to the diagram, after connecting the power wires to the battery, the capacitor C1 begins to quickly charge through the resistor R3. Upon reaching a certain degree of charge, the voltage through the resistor R4 and the LEDs begins to flow to the base of the opening transistor. At this point, relay P1 should operate. Closing, the relay contact prepares the circuit, which consists of a thyristor, relay contact P1, LEDs and capacitor C1. Through the dividers R1 and R2, a pulse from the X1 contact arrives at the control electrode of the thyristor.

There is an opening of the thyristor, as a result of which the capacitor is rapidly discharged through the LEDs. There is a bright flash of a flashlight.

Through the resistor R4 and the thyristor, the base of the transistor is connected to a common wire, which causes the transistor to close and the relay to turn off. At the same time, the glow period of the LEDs increases by several milliseconds due to the fact that the contact does not open immediately - due to the slight inertia and residual magnetization of the relay armature. After the contact nevertheless opens, the thyristor is de-energized. The electrical circuit returns to its original state until a new pulse passes. By changing the capacitance of the capacitor used, you can change the glow time of the LEDs: more capacitance - they glow longer and brighter, but the trail from the mark on the flywheel is more noticeable.

How to use this strobe

With the help of a stroboscope made in a garage, you can easily and with great accuracy:

• set the ignition on the carburetor engine;
• check the spark plug or ignition coil;
• control the operation of the centrifugal and vacuum regulator of the ignition timing.

Homemade stroboscope is cheaper and more reliable

In order for the ignition timing to be set correctly, it must be assumed that the mixture is usually ignited a couple of degrees before the piston reaches the top point of the cycle. This angle is called the “ignition advance angle”. With an increase in crankshaft speed, the UOS should also increase along a given curve. As a result, the advance angle is set at idle and then controlled in all ranges of engine operation up to 5000 rpm.

When connecting a stroboscope, you need to wind its sensor (copper wire) directly onto the sheath of the high-voltage wire of the first cylinder of the internal combustion engine. Three or four turns is enough. At the same time, it is necessary to fix the wire in this way as close as possible to the candle - in order to minimize the influence of neighboring wires on the operation of the stroboscope. To power the device, its wires with "crocodiles" cling to the battery terminals. Also, for better visibility, the flywheel mark will additionally be marked with a white dot - paint or, for example, a clerical stroke.

1. Start the engine and warm it up to operating temperature, leaving it to idle between 600-800 rpm.
2. Connect the stroboscope power wires.
3. Wind the copper wire-sensor on the armored wire of the first cylinder.
4. Aim a flashlight, flash, laser, etc. on a fixed mark (located on the timing case).
5. Then look for the same moving point on the flywheel pulley.
6. If the moment is violated, the movable and static marks will be relatively far apart.
7. By rotating the housing of the ignition distributor, match the marks and fix the distributor in this position.
8. Next, you need to briefly increase the speed, as a result of which the marks will again disperse. But it normal. In this mode, the ignition is set earlier. To check this indicator, a pair of fixed marks is provided - after 5 degrees of ignition advance.
9. For 3 thousand rpm, UOZ in the case of VAZ engines is 15-17 degrees.
10. In order to check the serviceability of the spark plug, alternately wind the copper wire around the high-voltage wires and see if there are any missed pulses. A lower frequency of LED flashes will indicate a misfire, "breakthrough" of the candle on the body.

How to choose a car Today, the market offers customers a huge selection of cars, from which their eyes just run up. Therefore, before buying a car, it is worth considering many important points. In the end, having decided on what exactly you want, you.

Which sedan to choose: Almera, Polo Sedan or Solaris

In their myths, the ancient Greeks spoke of a creature that had the head of a lion, the body of a goat, and a snake instead of a tail. “The Winged Chimera was born from a tiny creature. At the same time, she sparkled with the beauty of Argus and horrified the ugliness of the Satyr. It was.

They appeared as a result of genetic modeling, they are synthetic, like a disposable cup, they are practically useless, like Pekingese, but they are loved and expected. Those who want a fighting dog get themselves a bull terrier, those who need an athletic and slender one give it away.

The cheapest car in the world - TOP-5 of 2016

Crises and the financial situation are not very conducive to buying a new car, especially in 2016. Only everyone has to drive, and not everyone is ready to buy a car in the secondary market. There are individual reasons for this.

Overview of the most popular crossovers and their comparison

Today we will consider six crossovers: Toyota RAV4, Honda CR-V, Mazda CX-5, Mitsubishi Outlander, Suzuki Grand Vitara and Ford Kuga. To two very fresh new products, we decided to add the debuts of 2015 for a test drive.

Many modern motorists face the need to adjust the ignition angle (UZ). Sometimes this procedure can cause certain difficulties for a motorist, so a lot of devices have recently appeared on the market to perform this task. For example, you can use a stroboscope to carry out the do-it-yourself ignition installation procedure, which we will discuss below.

[ Hide ]

stroboscope characteristic

So, you have decided to make the ignition settings on your car, but you have no idea how to set and adjust the UOZ. In order for the set angle not to bring discomfort to the driver while driving, you can use a stroboscope for ignition.

circuit diagram

Below is a diagram of the stroboscope. If you do not know how to make a stroboscope on your own with LEDs, you can use this diagram. In the end, you will get the simplest stroboscope, however, the device made will allow you to fully adjust all the necessary parameters.

In the device diagram, it is necessary to distinguish several main parts:

1. A power circuit that consists of components - SA1, which is a switch, a diode VD1, and a capacitor C2. A self-made circuit must necessarily include a diode designed to protect other components from erroneous polarity reversal. The capacitor performs the function of blocking impulse noise, helping to prevent malfunctions in the trigger. As for the switch, it can be replaced by a toggle switch, the main thing is that the component can turn the power on and off.
2. A homemade stroboscope for installing an ultrasound must include an input circuit consisting of a controller, resistors R1, R2, and a capacitor C1. The controller option in this case is performed by a crocodile clip, which is fixed on the high-voltage cable of the first cylinder. As for the components C1, R1 and R2, they form a simple differentiating circuit.
3. Another important component of the stroboscope used is the trigger board, which is assembled using two single vibrators designed to generate a given frequency signal at the output. Capacitors and resistors in this case are frequency-setting components.
4. Another component is the output stage, which is assembled on resistors R5-R9 and transistors VT1-VT3. The transistors themselves are designed to amplify the output current of the trigger. Resistor R5 allows you to set the base current of the first transistor. And thanks to the resistor R9, the probability of failures in the operation of VT3 is excluded.

Principle of operation

So, what is the principle of work. The stroboscope for installing the ignition with your own hands is in any case powered by a battery. When the switch closes, the trigger comes into operation. At this time, a high potential is formed on the inverse terminals 2 and 12 in accordance with the scheme, and a low potential is formed on the direct terminals 1 and 13. The capacitors C3 and C4 themselves are powered by resistors.

The signal from the controller, passing through the differentiating circuit, is transmitted to the input DD1.1, which is a single vibrator, which ultimately contributes to its switching. The field of this begins the overdischarge of C1, ending with the switching of the trigger. Ultimately, the one-shot begins to respond to signals from the controller, forming rectangular signals on the first output.

As for the second single vibrator DD1.2, its principle of operation is similar - it allows you to reduce the signal duration by ten times at output 13. This component operates under load from the amplifier stage of transistors that open for the duration of the signal. As for the current passing through these elements, it is limited by resistors R6-R8, its indicator should be no more than 0.8 amperes.

This figure is not very large, because:

• the signal itself lasts no more than one second;
• as a rule, the operation of this lasts no more than ten minutes, respectively, overheating of the crystals is unlikely to occur in such a short time;
• modern diodes are characterized by more optimal technical features compared to those used in stroboscope designs ten years ago.

Accordingly, the operation of brighter diode elements will make it possible to largely reduce the load current as a result of an increase in the resistance index. This resistance increases on circuit components R6-R8.

PCB and Assembly Parts

Assembling your own strobe is not a problem. With a small budget, you can use inexpensive parts, if necessary, you can create a more modern device.

1. On the board above, KD2999V is used as the diode element VD1, another one can be used, in this case it is important that the diode is with a small forward voltage drop.
2. Capacitor devices C2-C4 should be rated at 0.068 uF, and C1 is a high-voltage component with a voltage of 400 volts.
3. TM2 is a flip-flop with good noise immunity.
4. Transistor components VT1 and VT2 must have a high gain.
5. Diode parts HL1-HL9 should have the highest brightness, while their scattering angle should be minimal. The LEDs must be installed on a separate board, while there should be three of them in one row.

After the board for the device is ready, you need to choose a place to install it. For example, it can be a portable light housing, but it must be equipped with a hole in the housing for mounting the R4 regulator. In principle, you can use almost any case, the main thing is that you can easily install a regulator on it. You can learn more about how a home-made strobe for setting the ignition, made on the basis of a laser pointer, looks like from the video (the author of the video is Maxim Sokolov).

Features of device settings

To use the device, it must be adjusted. The tuning strobe must be set up properly to give the most accurate settings. First of all, the tuning resistor R4 is adjusted, which allows you to set the desired visual effect. As you turn the control knob, you will notice that lowering the signal can cause the marks to be underlit, and if the signal is increased, it will blur. Accordingly, during the first adjustment of the ignition timing with your own hands, you should correctly set the most optimal duration of light flashes.

There is one more thing to consider - the length of the cable that runs from the printed circuit board to the controller should be no more than half a meter. For the controller, you can use a 10 cm copper conductor, which should be soldered to the central core of the cable. When the connection is made, it is wound on the insulated part of the high voltage with three turns.

To increase the level of noise immunity, the winding procedure is carried out as close as possible to the spark plug itself. If you do not have copper, then you can use a crocodile clip - this component is soldered to the central core. In this case, the teeth of the crocodile should be slightly bent, otherwise this may damage the insulation.

Properly set ignition timing is the key to stable stable operation of the entire motor. Moreover, fuel consumption directly depends on ignition. In this article, I propose to consider the option of optical tuning of your car's motor using a stroboscope.

For this procedure, you will need the following tools:

1. Stroboscope.

2. The usual set of automotive tools.

3. Dielectric gloves.

Now in more detail.

First of all, you need to drive the car out of the garage. It is desirable that there is no light interference, for example, blinding or glaring sunlight, it is best to do this work in the afternoon. Carefully inspect the stroboscope for the absence of any mechanical damage on its body. Be aware that serious injury can result from contact with the high-voltage strobe converter circuit.

Next, turn off the engine, then using the clamps (be sure to observe the polarity), connect the device to the battery. Be careful that, God forbid, a short circuit does not occur, this can happen if the contact wires are connected incorrectly. In order to avoid trouble, read the instructions that came with the device. Then fasten the signal cable to the wire that is connected to the spark plugs of the first cylinder, thereby forming a capacitive coupling with the device.

Wires must be arranged in such a way that they cannot get into the rotating parts of the machine. Now you need to find a mark made with white paint on the pulley or flywheel of the crankshaft. After that, it is necessary to determine the same marking on the body of the power unit. Follow safety precautions, take off any metal objects: chain, bracelet, watch, etc. Place the shift lever in neutral position.

Next, put on the previously prepared dielectric gloves. Make sure that there is no contact of moving mechanisms with parts of the body or any items of clothing. After that, start the car engine and let it run, wait for the idle speed to stabilize. Then slightly loosen the mounting bolt that prevents the distributor from turning.

Let's go further. Take a strobe light and point its lamp at the crankshaft pulley to illuminate the mark on the housing and the risk on the engine. Slowly, without haste, turn the distributor body, achieving the maximum coincidence of the markings. When everything matched, the motor can be turned off and the strobe turned off. Now fix the distributor housing by tightening the mounting bolt.

Now you can test the machine in action. In order to check the correctness of the ignition adjustment, accelerate the car to 50 km / h on a flat stretch of road. Then sharply press the gas, in the event of detonation knocks that will last no longer than two seconds, we can safely conclude that the work of adjusting the ignition with a stroboscope was a success. We close the hood, fold the tool and enjoy the positive result.

It is no secret that many of the problems that sometimes arise with a car can be corrected even by a novice car owner. Despite the apparent complexity of the mechanism, sometimes you can avoid another call to a service center or buying another unit for replacement. Anyone who wants to save money on the purchase of a device of not very high quality can independently make, for example, a stroboscope, which is designed to install the ignition. Many beginners may be put off by one name that seems too complicated and pretentious, but do not rush to conclusions. To know how to make a stroboscope for installing an ignition without buying an identical factory device, you should familiarize yourself with several suggested methods and stock up on all the necessary materials. For those who are not confident in their abilities, it will be enough to go to an auto shop at least once and find out about the cost and quality of a production stroboscope.

In fact, almost most car owners resort to the use of conventional gas discharge lamps to create this cunning device. True, such devices cannot be distinguished by long-term operation, especially since a lamp that once failed in its cost does not differ too much from the amount for which a new stroboscope can be purchased. All this together can push the motorist to create his own device. Consider the simplest and most affordable methods for creating a stroboscope.

"Advantages" of factory devices

Before dwelling on the purchase of a standard factory strobe, it is necessary to study in detail all its features and learn about the principle of operation. So, initially we will deal with the scope of this device. A device called a strobe light allows the owner of a car to easily adjust the ignition. With this device at hand, you can significantly speed up the entire. Equipped with a lamp, the unit gives signals about the presence of a spark, so you can quickly and correctly set the required ignition timing.

It is impossible not to note the efficiency and accuracy of workable factory instruments that are able to cope with this task in just a few minutes. However, despite such advantages, for some reason, the vast majority of motorists are trying to create such a unit with their own hands, slowly buying a production version. Most likely, this aspect is due to the rather high cost of stroboscopes. The overwhelming majority of factory models are equipped with expensive gas-discharge lamps, the subsequent replacement of which at a price becomes equal to the purchase of a new device. Commercially available factory counterparts are sold in the price range from 1000 to 6000 rubles (a simple Multitronics will cost the buyer 1000 rubles, Astro L5 1300, Focus F1 1700, and Focus F10 5600 rubles).

If desired and the need arises, such a device can be created independently, it is enough just to find all the materials that include the simplest and most ordinary things that everyone has in their garage. A simple car strobe can be made from a flashlight, LEDs, and even a simple laser pointer. Despite the almost complete pricelessness, a do-it-yourself device can serve no less durable and reliable, proving the effectiveness of the service in practice.

The principle of creating the device

A stroboscope for setting the ignition is especially necessary for those who have a car. This is due to the peculiarities of the setting, since it is difficult to imagine even in the mind, not to mention reality, to correctly adjust the ignition timing, which is present on contact distributors and all contactless distributors. To do in such a situation without a stroboscope simply will not work. Moreover, using the services of this most accurate device, you can set the ignition with extreme accuracy in just 7-8 minutes. This indicator, as well as other important elements of the car, must be given due attention, since without it the normal functioning of any vehicle is impossible. The need for such a product, the high cost of the factory version in the store and the availability of the necessary parts simply push a person to create his own stroboscope.

List of Required Parts

Before you go to the store to buy all the parts described below, you should carefully examine all the materials and parts present in the garage, it is quite likely that most of them have been collecting dust on the shelves for a long time without much need. If you find most of the elements stored among waste materials for the manufacture of fixtures, the final cost of a finished and perfectly functioning stroboscope will not exceed 100 rubles, which will save money for other needs. The first thing you need is a simple cheap Chinese-made flashlight. It would be better if it turns out to be LED. In the event that the available model turns out to be a lamp one, it will be necessary to additionally purchase or remove all the required LEDs from the old lamp.

In addition to the case, you will need an electronic filling, to create which you need the following elements:

• a transistor of the KT315 type, which is probably stored in a discarded Soviet-style radio receiver;
• thyristor KU112A, it can be found in the power supply of an old TV;
• a capacitor designed for a voltage of 16 V;
• diode with low frequencies;
• 12 V relay, however, you should choose a small part that can fit in the flashlight body;
• several "crocodiles";
• a coil of wires, and 0.5 meters of which must be shielded;
• a small piece of copper wire.

Despite the large variety of circuits created for the correct serial assembly of the device, the newly minted strobe creator will need one in any case. In addition to having all the details described, it is necessary to arm yourself with a soldering iron, it would be better if the car owner has at least minimal skills in using it.

To assemble this device, you need to connect all the parts in series with the available wires and solder them securely. Through the rear hole in the lantern, you will have to pass all the necessary wires that will provide uninterrupted power to the stroboscope. If the selected flashlight model does not have a side hole, the car owner must make it with his own hands. This is necessary in order to bring out a shielded wire, at the ends of which a copper wire will be soldered to the central core. It is this element of the created device that will be a special signaling sensor.

The principle of operation of the device

So, after creating such an important device as a home-made car strobe, you should understand the principle of its operation in order to continue to freely adjust the ignition angle correctly. A capacitor, to which an electric current is supplied, is charged by means of a resistor. Upon reaching the charge of the required level, the current is supplied by a resistor to the opened transistor. It is at this time that the relay begins to work, which is designed to create a circuit that includes a thyristor, diodes and a capacitor. The whole unit is a specialized divider through which the charge passes to the main contact of the thyristor. The opened control element entails the discharge of the capacitor, which is expressed by lighting diodes. The flash of light that appears in the flashlight goes out. The main output of the transistor is connected to the center wire by means of a thyristor and a resistor, as a result of which the transistor closes and the relay turns off.

The stroboscope for setting the ignition signals a long glow of the diodes, this occurs due to a broken contact with a delay. After some time, the contact is de-energized and interrupted. The self-made device again finds a position of inactivity, flashing at the moment of the next impulse. To achieve a brighter glow of the LEDs in the lantern, you can use a capacitor with a larger capacity.

Creating a stroboscope on a chip

The simplest stroboscope for setting the ignition is to create a device that is based on the DD1 chip, which is a single vibrator. Several diodes are connected to this microcircuit, which help to protect it from possible errors that occur at the time of connection. Before the next pulse hits the microcircuit, it is in its usual calm state. The system is equipped with two different outputs, the first one being low and opposed by a high inverted output. Accordingly, the connected capacitor is connected with a plus to the inverse output, due to which it is charged. The impulse passing through the entire microcircuit "clings" the trigger, behind which the charged capacitor is connected to work. The whole process goes directly through the resistor. The soldered DD1 chip responds to the electric current that has arrived at it, displaying the energy by glowing LEDs.

Conclusion

If we consider the technical side of the functioning of a do-it-yourself stroboscope, it is worth noting its effectiveness, which is in no way inferior to the work of a factory device. connects to the power unit and ignition. The person who assembled such a unit himself must remember that one of the "crocodiles" clings to the wire that leads to the first cylinder. To ensure the correct and uninterrupted operation of the device, it is necessary to study the principle of its operation in advance and correctly assemble all the parts. At that moment, when the engine goes through the point where a spark occurs, the car strobe, receiving another electrical impulse, responds with a flash of LEDs. Using such a moment, the motorist must correctly set the ignition.
