Do-it-yourself electronic gas lighter. DIY gas stove lighter. How to make a lighter from a shell

Various industrial-made electric arc lighters are available for sale on Chinese websites. But you can make such a lighter for gas stoves with your own hands.

The idea is to get a high voltage, high frequency, which creates a hot arc. Using this arc, you can easily ignite household gas, paper or cigarettes.

The lighter consists of several units:

1. Charging board for one Li-ion battery with built-in over-discharge protection. The board has several indicator LEDs, one of which is on during the charging process, and the other is on when the battery is fully charged. The presence of such a board will allow you to charge the battery with a current of up to 1 A from any 5 V source, for example, from an ordinary USB port.

1. Li-ion battery will fit any size and capacity. The example uses an 18490 1400 mAh battery. It is slightly shorter than conventional 18650s. The choice is due to the overall dimensions of the lighter body.

1. A converter built according to a simple self-generating circuit based on the IRFZ44 field-effect transistor and a high-voltage transformer. You will have to wind the transformer yourself.

The transformer was based on a core from an electronic transformer for 50 W halogen lamps. A core from a computer power supply room is also perfect.

The transformer must be carefully evaporated, disassembled and removed from the standard windings. The mains winding must be saved - it will still come in handy.

The halves of the core are glued to each other, so before undocking they need to be warmed up a little with a soldering iron so as not to break.

The primary winding consists of 8 turns with a tap from the middle. The index finger is used as an approximate measure.

The winding is wound with two buses, each of which consists of 4 cores of 0.5 mm wire, which was taken from the mains winding of the previously disassembled transformer.

After winding, the primary winding is insulated with 10 layers of ordinary tape. A secondary or step-up winding is wound on top.

To wind the secondary winding, a wire from the relay coil was used. Any compact 12 or 24 V relay will do. Wire diameters can be between 0.08 and 0.1 mm.

First, you need to solder a piece of stranded wire in insulation to the thin wire of the winding, and then wind it. The wire is not cut at any stage of winding. The winding is wound in layers, and each layer can contain from 70 to 100 turns. Insulation is placed on top of each layer with the same tape. As a result, you should get about 800 turns.

Next, the halves of the core are fixed, and a piece of stranded wire is soldered to the second end of the secondary winding. It will not hurt to ring the winding with a multimeter to check for integrity. The final insulation is then applied using electrical tape.

After completing all these procedures, it is necessary to phase the primary winding. The beginning of one shoulder must be connected to the end of the other. This is the middle point where the plus is connected from the power source.

Further, the circuit of the oscillator is assembled and tested for operability. The high-voltage arc is formed already at a distance of half a centimeter and stretches up to 1 cm. This indicates the normal operation of the inverter.

Now everything can be installed in the case.

The FET has not been installed on the heatsink, but it is highly recommended to do so. It is also recommended to hide all exposed parts of the circuit under heat shrinkage.

This post has a great idea on how you can make an electric match with your own hands. To do this, you will need an 18650 battery, electrical tape, nichrome wire, wire cutters, tongs, ordinary wire, 2 clinic, a stationery knife, sandpaper, a plastic clamp.

If you do not want to make such a design yourself, then take a look at this store, which is interesting for lovers of all kinds of useful and inexpensive things.

Actions step by step

First you need to take the wire and align it perfectly. A small piece will suffice. Now you need to cut it in the middle. It turns out two contact wires that need to be attached to the poles of the battery and bent at an angle of 90 degrees. Now we take one wire, apply it to the battery and bend it approximately in the middle. We do the same with the second wiring.

Now we strip these two wires from the insulation on the side that will lie on the battery. We install one wire on the battery and fix it with electrical tape. At the end of the second piece, make a ring with tweezers. We also fix it on the battery with electrical tape. Next, we take a nichrome wire with a diameter of 0.4 mm and wind it on a thin screwdriver or a nail, make 3-4 turns.

Now you need to pull out the metal parts from the two terminal blocks. Next, you need to take a battery and leave 0.5 centimeters at the ends of the wire. We fasten the terminal blocks to these contacts.
We take a nichrome wire spiral and bend the contacts. We insert the spiral into the terminal blocks and fasten it. We install the clamp between them. The electric lighter is ready. Now you can check it

The battery operated electric lighter can be charged using a standard charger.

The second model of a homemade electric match

In this plot of the TOKARKA video magazine, we will consider a solid and difficult-to-manufacture model of an electronic match that will perfectly serve when gas or gasoline runs out. It runs on a single finger battery or rechargeable battery. In this case, a 1.2 volt battery with a capacity of 2400 milliamps is used.
The head part is made of duralumin. The button is made of brass. The switch has a contact pad and an outlet for the filament. Another platform will be outside, it will be fixed with a small screw. There is a spring from the remote control inside the case. A battery will be installed on top of it.

Studs from the motherboard's contact pad are used as racks for filaments. Copper wires of sufficient rigidity can be used instead.

Nichrome thread was used from a faulty hair dryer. It is necessary to select the length of the filament so that it does not run red hot. It is desirable that the temperature on it be 500-600 degrees, but no more. When it heats up to red, a reaction occurs with air and it will gradually burn out, so you have to change it. You can experiment and find the temperature at which the coil is very hot, enough to ignite objects, but not hot. It may be a dark, dark cherry color, but not bright.

The Chinese electric lighter is quite easy to use, but this does not guarantee that it will last. The scheme of a Chinese lighter becomes a stumbling block for many radio amateurs trying to fix it. We do not recommend that you bother too much about this, it is not worth it. Although, the very device of the Chinese lighter is very interesting, and can be taken as a basis for many amateur radio developments.

Chinese electric lighter, its advantages and disadvantages:

Many housewives are happy to acquire electric lighters without hesitation and unaware of the danger.

Picture №1 - Chinese lighter

First, you should pay attention to the insulation, despite the fact that outwardly the body of the lighter looks reliable. There is a great opportunity to get an electric shock, not fatal but also unpleasant.

Secondly, Chinese lighters ignite gas poorly; when using them, you must be extremely careful and follow all safety rules when using gas equipment.

Thirdly, more than one radio amateur could not resist the temptation to just take and disassemble an electric lighter and see what it has inside :)

Figure №2 - Examples of disassembled Chinese lighters

Such lighters, as a rule, operate on two AA batteries, that is, from 3 Volts, and for a long enough time, which is its big plus.

Figure №3 - A common scheme of a Chinese lighter

Closing the contact (button) at the output of the lighter, the voltage is about 6-7 kV, and this energy is enough for air breakdown of about 5 mm.

As a rule, most lighter circuits use a bipolar transistor of the S8550D series (pnp, 25 V, 1.5 A), it is included in the boost converter circuit.

An increased voltage of about 50 volts is generated on the secondary winding of the step-up transformer.

After that, the voltage is rectified, and the PCR606J thyristor (600 V, 0.6 A), operating in the key mode, transmits short-term pulses to the primary winding of the high-voltage coil.

The coil is sectional, the resistance of its secondary winding is approximately 355-365 Ohm.

The primary winding of the coil is wound on a 0.04 mm ferrite. copper wire, and is 15 turns.

As a rule, a thyristor flies in these lighters, and in the event of a breakdown, you just need to replace it with a similar one. The same thing happens with a transistor.

But in my opinion, if your Chinese lighter is broken, then just throw it out and don't fool your head over repairing it, it's not worth it.

But it is very advisable to take as a basis for many amateur radio developments and designs, since the generator is made on cheap and affordable elements.

A lot of interesting and useful information awaits you at

A simple, economical, home-made lighter for igniting gas. 12 parts. Power supply 1.2 V. The first converter, an asymmetrical multivibrator, is assembled on the VT1-VT2 transistors. The winding of 1 transformer Tr2-step-up transformer is connected to the VT2 collector circuit. From its secondary winding, high-frequency voltage is supplied to the rectifier diode. The rectified voltage charges the capacitor C2, which in turn opens the thyristor VS1, the open thyristor closes the charged capacitor to winding 1, high-voltage transformer Tr1. A high-voltage discharge occurs on winding 2. The capacitor is discharged, the thyristor is closed, and the storage capacitor is charged again C2.

Transformer Tr2, taken from a broken phone charger. To pull out the ferrite core, it needs to be heated. On the frame, after removing the windings, wind 500 turns of wire with a diameter of about 0.08 mm. This will be winding 2. Next, isolate the winding with one or two layers of tape and wind the primary winding in the same direction as the secondary. It contains 10 turns of wire with a diameter of about 0.4-0.8 mm. How to check the operation of the converter is shown in the video.

High-voltage transformer Tr1, second voltage converter, They are wound on a ferrite core from a magnetic antenna of a radio receiver of long and medium waves. With a cloth for cutting tiles, I shallowly sawed the ferrite in a circle. Then I just broke it with my hands. The length of the ferrite took 3 cm, but you can probably even less. Wrap the ferrite with one layer of tape, glue on the sides "cheeks", and wind the high-voltage winding-2. The first output of this winding, which will come out of the coil, must be MANDATELY threaded into PVC insulation to prevent it from breaking from bending. layers of adhesive tape, making sure that the edges of the tape go over the cheeks, otherwise there will be a breakdown in this place. a thin wire, it can be welded with a lighter. Twist the two wires, and heat the end of the twist until a round appears. Then gently pull the two wires, and you can but continue winding further. Insulate the high-voltage winding with three layers of tape, and in the same direction as the secondary winding, wind the primary. It contains 10 turns of 0.6-0.8mm wire. A layer of adhesive tape and the coil is ready.

Finished coils.

I selected transistors, and found the best option for the operation of the first converter. These are the common transistors kt361 and c3205. Instead of kt361, kt3107 is suitable. Instead of c3205-kt815, s8050, bd135. Thyristor did not pick up, because. it is also widespread, but it will certainly fit from the same series mcr100 -... Resistors R3-R4 serve for the opening threshold of the thyristor. By selecting them, you can power up the spark at the output. The diodes must be fast-switching, see datasheets. Suitable: ps158r; fr155p ; fr107; fr103.

The arc igniting the gas is about 5-6 mm long. Shorter arc length - the gas will not ignite. The arc is not dangerous, tingling sensation, like from a piezo lighter. The battery should be enough for a long time. I tested it for an hour with a battery with a capacity of 2800mA * 1.2V, left it on , and for an hour the sparks were smacking on my table. I checked the battery and it did not run out.
Here are two videos on how to make a lighter to ignite a gas-gas stove.

Of course, it will not be difficult to buy an electric lighter for a gas stove today. They are in bulk on the market, and the cost allows anyone to buy it. In this article we will look at how you can assemble such a lighter yourself. This will be very useful, as it will allow you to find out its principle and possibly apply it in other homemade products.

The main idea here is to obtain a high voltage with a high frequency, as a result, a hot spark is formed between the electrodes. This spark can ignite gas, cigarettes, or paper. Let's consider in order how to do it.

DIY materials and tools:
- soldering iron with solder;
- charging for li-ion batteries;
- li-ion battery (18490/1400 mAh);
- field-effect transistor IRFZ44;
- transformer for 50 W halogen lamps (or other similar);
- wire 0.5 mm (must be in the transformer);
- frame;
- power button and other little things.

Lighter making process:

Step one. Preparing the charger
To charge the Li-ion battery, the author used a special board with protection. There are two indicators on the board, one is on when charging is in progress and the other is on when the battery is low. With the help of such a device, the battery can be charged with a current of up to 1A through any 5V source. Alternatively, this can be done via a regular USB port.

Step two. Battery
The DIY battery is suitable for any size and capacity. As an example, the author installed an 18490 battery with a capacity of 1400 mAh. Its peculiarity is that it is somewhat shorter than an ordinary 18650. In general, the choice depends on the size of the lighter.

Step three. Converter
An IRFZ44 type transistor and a high voltage transformer were used as the basis for the converter. The most difficult thing is to deal with the transformer, you will have to wind it yourself.

The transformer will need a core from an electronic transformer of 50 W halogen lamps. A standby voltage transformer from a computer power supply is also suitable for such purposes.
First, the transformer must be carefully evaporated and the installed windings removed. The network wiring must be left, it will come in handy for DIY. To disconnect the halves of the transformer, they need to be warmed up with a soldering iron.

The primary winding has 8 turns and is tapped from the middle. The author measures everything roughly with his finger.

The wiring is wound with two buses, with each bus having 4 cores of 0.5 mm wire. The wire came in handy the one that was used as a network winding in the previously disassembled transformer.

After the primary winding is wound, 10 layers of adhesive tape are wound on top for insulation. Then the author winds the secondary or step-up winding from above.
The secondary winding was wound with wire from the relay coil. As for the relay, any small 12-24V will do. The diameter of the wire should be within 0.08-0.1 mm.

First, you need to solder a piece of stranded wire to the thin winding wire, and then start winding. The wire does not need to be cut at any stage of winding. You need to wind it in layers, with each layer containing 70-100 turns. On top of each layer there is insulation, which is also made from scotch tape. In conclusion, about 800 turns should come out.

Now you can fix the halves of the core, and a piece of stranded wire must be soldered to the second end of the secondary winding. You can also ring the winding with a multimeter to check its integrity. The final insulation is electrical tape.

In conclusion, you need to do the phasing of the primary winding. The beginning of one shoulder is connected to the end of the other. As a result, a midpoint is formed, to which the plus is connected from the power source.
Then you can assemble the oscillator circuit and check if everything works. The arc should form at a distance of 0.5 cm, and it can be stretched up to 1 cm.If this is the case, then the inverter is working correctly.
