How to make a lighter for a gas stove

The wiring diagram of a simple gas lighter

Today let’s take a look at Chinese gas lighters that work with finger batteries. The price of such devices does not exceed 1 (in some cases no more than 0.5). Such lighters are fully electronic. Inside you can find a compact circuit board, which has several components.

Scheme of a lighter for gas, consists of two main parts:

These lighters are designed to work with one or two 1.5 volt finger batteries. Can work for a long time on one token battery, with two batteries should not be switched on for a long time. In operation, there is an air breakdown at the output of no more than 0.5cm. Output voltage of the circuit is about 6-7 volts.

The step-up converter consists of only three components:

Scheme. blocking generator. On the secondary side an overvoltage of about 50 volts is generated. Often a S8550D series bipolar transistor (p-n-p, 25 V, 1.5 A) is used in these circuits. The voltage is then rectified. Thyristor PCR606J (600 V, 0.6 A) operates in the key mode, supplies short pulses to the primary winding of the high voltage coil. The coil itself is sectional, the secondary resistance is about 355-365 Ohm. The winding is wound with copper wire, diameter is about 0.05mm. The primary winding is wound on a ferrite core and consists of 15 windings, 0.4 mm wire.

Piezo lighter

It is a universal device, which functions without flint, the need for additional charging or recharging, access to mains. The piezo lighter for the gas stove is equipped with wear-resistant crystals, the lifetime of which is measured in decades. These appliances are safe to use in the kitchen, have an ergonomic shape of the body, are simple and mobile.

Repair of piezo lighter is required only when the resource of the main element, which is responsible for the production of the spark is exhausted. In the case of malfunctions you should not try to restore functionality by yourself. Like any household appliance, the piezo lighter for a gas stove must be restored by a specialist. This approach to solving the problem will not only save time and effort, but also money.

Thyristor gas lighter

All modern gas stoves and boilers are equipped with an electronic gas ignition system. But if your stove doesn’t have an electric ignition system, this circuit will come to the rescue:

On two transistors and a transformer the step-up converter is assembled, on a thyristor the second generator is assembled, which periodically closes the capacitor to ground, connecting it to the transformer coil T2.

At the moment of power supply the voltage at the output of booster converter is close to zero and the current is maximal and goes through the diode, discharged capacitor and the primary winding of transformer T2. The capacitor starts to charge, its resistance increases, the current in the circuit decreases and the voltage increases. voltage divider is built in the resistor R3 R4, the voltage across the resistor R3 is 180 times less than the output voltage of the converter. As soon as the voltage across the resistor R3 is greater than 0.7V, the thyristor opens and starts discharging the capacitor through the primary winding of transformer T2. The voltage on the secondary side is about 100 times higher than on the primary side, a spark discharge occurs. The capacitor rapidly discharges and as soon as the current through the thyristor is less than the holding current, the thyristor closes.

Resistor R1 can be used to control the current consumption in a small range. The elements C1 and R2 set the frequency of the converter pulses. With resistor R3 you can adjust voltage up to which the capacitor will be charged. If this resistor is increased, the capacitor voltage grows, but the risk of thyristor breakdown increases. The frequency of spark discharges depends on the capacitance of capacitor C2.

You can take any transistor Q1, n-p-n structure with collector current not less than 0.1A, Q2. of p-n-p structure and current not less than 0,5A. Since the frequency of the converter is rather high, the diode D1 is a pulse diode, but you can use ordinary 1n4005-1n4007, I didn’t notice any difference. thyristor Q3 is better to take PCR606, MCR100-8 or others with voltage anode-cathode not less than 600V and current 0.8А. I had no thyristors for 600V, but I had a lot of PCR406 from old clothes. But they kept breaking, and I burned 15 of them while I was tuning the circuit. As far as I understand to avoid breakdowns you need to decrease resistor R3 down to 1 MΩ. Another reason for the breakdown could be the high voltage bleed from the primary of the T2 at the time of thyristor closure.

Transformer T1 is wound on a ferrite dumbbell, the primary winding is 30 turns of 0.1-0.2mm, the secondary winding 500 turns of 0 wire.08mm wire. between the windings one layer of scotch tape.

Transformer T2 is the most time consuming element. There are two options: layer-by-layer or section-by-section winding. I wound a few bobbins in layers, but they all got punctured around the edges, so I decided to make a sectional frame. The easiest option, find insulating washers of the right diameter. I found 12 gethinax washers, which after a little machining with a drill and a circular file, sat tightly on the syringe:

After putting on the washers it is necessary to make a cross cut on the washers for wire transition from one section to another and treat all the irregularities with an emery board to reduce the risk of wire breaks. First the secondary coil is wound. Wire diameter 0.08mm, number of turns. 2500, 220-240 per section. The primary winding has 25 turns of wire with a diameter of 0.5 mm.1-0.3mm, and wound on an 8mm ferrite rod. The winding is covered with duct tape, for insulation and to make the coil fit tightly into the syringe.

I used the battery from an old phone. It already has a protection circuit board. Just need to remove some plastic around the pins to solder the wires better.

The button used is km1-1 with a nut hole mount. On the printed circuit board is placed all the elements of the design, except for the button and the battery.

The circuit board is drawn with nail polish and etched in ferrous chloride:

All this fits in a tube with a diameter of 50mm. I covered both sides of the tube with some kind of drug caps, the board fit tightly. The empty space between the board and the battery is filled with foam rubber to keep the battery from hanging out. The lids are attached with small self-tapping screws to the sides of the tube. To screw in the self-tapping screws easier the holes were drilled beforehand.

During the test it turned out that the button sometimes jolts with current, not strongly, but unpleasantly. The high-voltage transformer must be more reliably insulated:

Lighter for the gas stove

So conventionally we can call electric lighter, used for lighting the gas burners of gas stoves. Very convenient and safer in terms of fire than the household matches used for this purpose. In principle, you can buy an electric lighter. if you can find it in a hardware store. But it can also be made by our own hands, which is more interesting from the technical point of view, and it needs few radio components. Two variants of homemade electronic “match” are described below. with power from the electric light grid and from a single small battery D-0,25. In both variants reliable ignition of gas is carried out by an electric spark, created by a short current pulse of voltage 8 kV, which can be made with a small battery. 10 kV. This is achieved by appropriately converting and increasing the voltage of the power supply. The circuit diagram and the design of the mains lighter are shown in Fig. 1. The lighter consists of two assemblies connected by a flexible two-wire cord: a plug adapter with capacitors Cl, C2 and resistors Rl, R2 inside and a voltage converter with an arrester. This design solution ensures its electrical safety and relatively low weight of the part of it, which is held in the hand when igniting the gas. How the device works as a whole? The Cl and C2 capacitors act as elements limiting the current drawn by the lighter to 3. 4 mA. As long as the SB1 button is not pressed, the lighter consumes no current. diodes VD1, VD2 rectify AC mains voltage, and pulses of rectified current charge the capacitor CЗ. Over several periods of line voltage, this capacitor is charged to the opening voltage of dinistor VS1 (for KN102Zh). about 120V). Now the capacitor is quickly discharged through the small resistance of the open diistor and the primary of the step-up transformer T1. This results in a short current pulse, which can be several amperes. This results in a high voltage pulse on the secondary of the transformer and an electrical spark between the electrodes of arrester E1, which ignites the gas. And so on. 5 to 10 times per second, t. е. with a frequency of 5. 10 Hz. Electrical safety is ensured by the fact that in case of insulation failure and in case a hand touches one of the wires connecting the plug adapter with the converter, the current in this circuit will be limited to one of the capacitors Cl or C2 and will not exceed 7 mA. Short-circuiting between the connecting wires will not lead to any dangerous consequences either. The arrester is also galvanically isolated from the mains this sense also safe. Condensers Cl, C2, which nominal voltage must be at least 400 V, and their shunt resistors Rl, R2 are mounted in the body of the plug adapter which can be made from insulating sheet material (polystyrene, plexiglass) or a plastic box of supply dimensions can be used for this. The distance between the centers of the pins that connect it to a standard wall outlet should be 20 mm.

Rectifier diodes, capacitor СЗ, dynistor VS1 and transformer Т1 are mounted on the circuit board of 120Х XI 8 mm dimensions, which after checking is placed into the plastic case-pen of corresponding dimensions. The step-up transformer T1 is built on a 400HH ferrite rod with a diameter of 8 and a length of about 60 mm (a part of the rod, designed for the magnetic antenna of a transistor receiver). The rod is wrapped with two layers of insulating tape, over which the secondary winding is wound. 1800 turns of PEV-2 wire 0,05-0,08. Winding in bulk, smoothly from edge to edge. It should be sought that the order numbers of the overlapped turns in the layers of wire would be from one hundred. The secondary winding has two layers of insulation tape wrapped around its full length and 10 turns of 0.4-0.6 PEV-2 wire wound in one layer on top of it. primary winding. KD105B diodes can be replaced by other small-sized diodes with a permissible reverse voltage of at least 300 V or diodes D226B, KD205B. Capacitors С1-СЗ of БМ, МBМ types; the first two of them must have nominal voltage of not less than 150 V, the third one. at least 400 V. The constructive basis of arrester E1 is a piece of metal tube 4 with the length of 100. 150 and a diameter of 3. 5 mm, on one end of which is rigidly fixed (mechanically or by soldering) metal thin-walled cup 1 with diameter 8. 10 and a height of 15. 20 mm. This cup, with slits in the walls, is one of the electrodes of arrester E1. Inside the tube together with a heat-resistant dielectric 3, for example, a fluoroplastic tube or a tape, a thin steel knitting needle 2 is tightly inserted. Its sharpened end protrudes from the insulation by I. 1.5 mm long and should be placed in the middle of the beaker. This is the second, central, electrode of the arrester. The discharge gap of the lighter is formed by the end of the central electrode and the walls of the cup. it should be 3. 4 mm. On the other side of the tube, the central electrode in the insulation must protrude at least 10 mm. The tube of the arrester is firmly fastened in the plastic body of the converter, and then the electrodes of the arrester are connected to the leads of the transformer winding II. Insulate the soldering points reliably with pieces of PVC pipe or insulating tape. If at your disposal will not be available dinistors KN102Zh, it can be replaced by two or three dinistors of the same series, but with a lower switching voltage. Total opening voltage of such a dynistor chain must be 120. 150 В. In general, the diodistor can be replaced with its analog, composed of a low-power trinister (KU101D, KU101E) and a stabler, as shown in Fig. 2. The stabilizing voltage of a stabilizing diode or series connected in series must be 120. 150 В. The schematic of the second version of the electronic “match” is shown in Fig. 3.

Because of small accumulator voltage G1 (D-0,25) it was necessary to apply two-stage transformation of supply voltage. In the first such stage operates the generator on transistors VT1, VT2, assembled according to the multivibrator circuit [L], loaded on the primary winding of the step-up transformer T1. This induces on the secondary winding of the transformer an alternating voltage of 50. 60 V, which is rectified by diode VD3 and charges the capacitor C4. The second stage of transformation, which includes the dinistor VS1 and the step-up transformer T2 with the arrester E1 in the secondary circuit, works the same way as a similar unit of the mains lighter. Diodes VD1, VD2 form a single half-period rectifier, periodically used to recharge the battery. Capacitor C1 dampens excessive line voltage. Plug XI is installed on the body of the lighter. The assembly board of such lighter version is shown on fig. 4. The magnetic circuit of the high voltage transformer T2 is a ring of ferrite 2000 NM or 2000HH with outer diameter of 32 mm. The ring is carefully broken in half, the parts are wrapped in two layers of insulating tape, and on each of them are wound in tandem 1200 turns of wire PEV-2 0,05-0,08. Then the ring is glued with BF-2 or “Moment” glue, the halves of the secondary winding are connected in series, wrapped with two layers of insulating tape and the primary winding is wound over it. 8 turns of PEV-2 wire 0,6-0,8. Transformer T1 is made on a ring of the same ferrite as the magnetic core of transformer T2, but with an outside diameter of 15 mm. 20 mm. Same manufacturing technique. Its primary winding, which is wound on the second winding, contains 25 turns of the wire ПЭВ-2 0,2- 0,3, the secondary. 500 turns of PEV-2 0.08-0.1. Transistor VT1 can be KT502A- KT502E, KT361A- KT361D; VT2. KT503A. KT503E. Diodes VD1 and VD2. Any rectifier diodes with allowable reverse voltage not less than 300 V. Capacitor C1. MBM or K73, C2 and C4. K50-6 or K53-1, S3. CLS, KM, KD. The turn-on voltage of the diistor used should be 45. 50 В. Design of the arrester is exactly the same, as of the mains lighter. Adjustment of this version of electronic “match” is reduced mainly to careful check of assembling, construction as a whole and matching of resistor R2. This resistor must be of such a rating that the lighter will operate steadily at a battery supply voltage of 0.9 to 1.3 V. It is convenient to control the battery discharging degree by the frequency of spark formation in the arrester. As soon as it drops to 2. 3 Hz, it will be a signal of the necessity of battery charging. In this case, plug XI of the lighter must be connected to a 6. 8 ч. When using a lighter, its arrester should be removed from the flame immediately after ignition. it will extend the life of the arrester.

For the car

Today, looking for alternatives to gasoline for cars is very relevant, because this type of fuel regularly increases in price. To save money many motorists look for alternative energy sources.

This is probably the best alternative to gasoline, as gas is half the price. The use of this fuel can reduce financial costs by about 40%. However, it should be taken into account that gas has some disadvantages.

  • Reduces the life of the engine by about 10%.
  • The luggage compartment will be significantly reduced in size, since it will be permanently placed a gas cylinder. But this is not a critical flaw.


Not the best option for savings, because it turns out only to reduce fuel consumption by a couple of liters.

It is only the difference in flow rate that will save money. But it is necessary to consider that the diesel engine has some disadvantages.

  • It has a lower dynamism compared to gasoline-powered.
  • In winter it is problematic to start the diesel car, because its fuel tends to freeze in the cold.


Not the most popular, but quite economical option. However, you should keep in mind that electric-powered cars are extremely expensive to maintain. over, in our country there are very rare gas stations that are designed for electric cars.

Finding an option to replace gasoline is possible, but not for all cases. For example, it is better to use original refined fuel for lighters or catalytic warmers. Otherwise, you can render the device unusable and harm your health.

How to fix a lighter

Piezo lighters tend to last much longer than mechanical lighters. The secret of their longevity is the absence of friction of the elements. However, if something happens to the piezo element, you can’t fix it. Dear friends, you can help financially to develop the channel and buy equipment for new experiments.

Classification of modern lighters has two main sections: The fuel used in the device and the ignition method. In the first case, everything is simple: the lighters can be filled with either liquid butane gas or liquefied propane. the flame can reach temperatures of up to degrees Celsius. or with gasoline vapors, the flame can reach temperatures from up to degrees Celsius.

Electric lighter for gas stove with my own hands

There are various commercial electric arc lighters available on Chinese websites. But you can make such a lighter for gas stoves with their own hands.

Make gas stove from a lighter (Life Hacks).

The idea is to get a high frequency voltage that produces a hot arc. With this arc, you can easily ignite household gas, paper or cigarettes.

  • Charging board for one Li-ion battery with built-in discharge protection. The board has several indicator LEDs, one of which lights up when the battery is being charged and the other lights up when the battery is fully charged. The presence of such a board will allow you to charge the battery current up to 1 A from any source of 5 V, for example, from an ordinary USB port.
  • The Li-ion battery is suitable for any size and capacity. In this example we use a 1400 mAh 18490 standard battery. It is a bit shorter than a normal 18650. The choice is based on the dimensions of the lighter.
  • A converter with a simple autogenerator circuit with an IRFZ44 field effect transistor and a high-voltage transformer. The transformer will have to be wound by yourself.

The transformer is based on a core from an electronic transformer for 50W halogen bulbs. The core from the computer power supply standby is also a good idea.

The transformer needs to be carefully unsoldered, disassembled and the regular windings removed. The mains armature must be kept because it is still useful.

The core halves are glued to each other, so before you undock them, you need to warm them with a soldering iron to prevent them from breaking.

The primary winding consists of 8 turns with a tap from the middle. Use your index finger as a rough gauge.

The winding is wound with two tires, each consisting of 4 strands of 0.5 mm wire, which was taken from the mains winding of the transformer disassembled earlier.

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

To wind the secondary winding a wire from a relay coil was used. Any compact 12 or 24 V relay will do. The diameter of the wire can be from 0.08 to 0.1mm.

Start by soldering a piece of stranded wire in insulation to the thin wire of the winding, and then wind it. No wire is cut off at any stage of winding. The winding is wound in layers, and each layer can contain from 70 to 100 turns. On top of each layer is insulation with the same scotch tape. The result should be about 800 turns.

Next, the halves of the core are fixed, and a piece of multicore wire is soldered to the second end of the secondary winding. It is also helpful to test the winding with a multimeter to check for continuity. Then the end insulation should be installed with duct tape.

After all of these procedures have been completed, the primary winding must be phased. The beginning of one arm should be connected to the end of the other. That’s how you get the center point, where you connect the plus from the power supply.

Next, the autogenerator circuit is assembled and tested for performance. The high-voltage arc is formed already at a distance of half a centimeter and stretched to 1 cm. This shows that the inverter is working properly.

The field transistor has not been mounted on the heat sink, but it is highly recommended to do so. It is also recommended that all exposed parts of the circuit are covered with heat shrink.

Wiring diagram of a simple gas lighter

A gas lighter, assembled according to the circuit in Fig. 4.60, have been in operation for several dozen, and they all work flawlessly. The construction of the lighters is simple, does not contain scarce parts, easy to set up. The peculiarity of the circuit is that it is supplied with AC voltage directly from the mains through the capacitor C1 and the resistor R1. Diode VD1 in this circuit operates in the mode of avalanche breakdown by reverse voltage, i.e.е. is, in fact, a fast-acting stableton, paired with a thyristor VS1 is analogous to a dinistor (for example, instead of them you can include two dinistors KH102B connected in series).

The diode VD2 protects thyristor VS1 from a reverse voltage of self-induction of winding I of transformer T1 and improves the work of generator. The generator generates short pulses with a frequency of several hundred hertz, which are then induced in winding II of transformer T1 to 10 kV and pierce the arrester.

Transformer T1. without a core, winded on a bobbin of kapron (Plexiglas, fluoroplastic) diameter 8 mm and consists of three sections, the width of each of which is 9 mm. It is convenient to use for T1 ready-made kapron sewing spools, gluing them together. First, winding II is wound by 3×1000 turns with PETV or PEV-2 wire of 0.12 mm diameter. The input wire end in each section must be carefully insulated with fluoroplastic tubing or lacquer cloth, otherwise a breakdown of the insulation will occur.

Whole coil T1 is waxed in water bath for few minutes. Then winding II in each section is wrapped with 2-3 layers of tape and on top of the insulation is placed the winding I. 3×10 turns of PEV-2 wire of 0.45 mm diameter. Resistor R1 is chosen with nominal value within 12. 16 kOhm. Diodes VD1. D219A, D220, D223; VD2. CD102A, CD105, D226B. Thyristor VS1. KU101E, G, you can also KU102, KU201, KU202 with reverse voltage of at least 150 V. It is convenient to use MP type microswitch as a button. Capacitors C1 and C2 are MBM type. K73, etc. to a voltage of at least 160 V.

The arrester in the represented is a paired insulated wire with steel or copper cores, which is placed inside a metal tube.

The tube at the end is drilled for the window. The wire is fixed on the output with epoxy glue. Adjustment of the lighter is reduced to the selection of diode VD1 until a reliable generation. Using tweezers move or spread the electrodes of the arrester wire to the optimal distance and to form a powerful spark. The latter, of course, is done with the lighter unplugged. Sometimes it is also necessary to select the capacitance C2. The body of the lighter can be any kind of case, for example, a toothbrush.
