The device has two operating modes. In the first position of the switch " norm"(I), it operates at half power: approximately 30-35W. In the second " turbo"(II) - 65-70W. The yellow LED shines in both modes, red only in the second. Indication LEDs are any, not bright ( AL307).

In order to make an electric burner you will need a cheap ($2-2.5) switching power supply (UPS) made in China, at 50-60 W, for halogen lamps. You can find them in stores around furniture fittings or in hardware stores.

Burner circuit

Schematic diagram of an electric burner based on ET

On the Internet, I came across a modification for making a pulse soldering iron. In the case of a burner, minimal modifications to the UPS will be required.

First, remove the board from the case and solder the output transformer. A lot has been written about these schemes, so I won’t go into details. It copes well as an electric burner. Let me just say that bipolar transistors MJE13003 (TUVE13007) can be replaced with more powerful current ones - MJE13005, MJE13007 (last digit means operating current). When choosing a UPS, you need to take into account the fact that it should not be protected from short circuit!

So, having removed the transformer from the board, it must be disassembled. A lot has also been written about disassembling ferromagnetic transformers. But, I will share my experience. First of all, remove the film and use a knife to remove the glue on the core connection. Afterwards, heat in small capacity water to a boil. But we don’t immediately throw it into boiling water, but heat it first with warm water. Due to the fact that the quality of these trances is very low, they can break. Therefore, after warming it up a little, we put it in boiling water and leave it there for a few seconds. The procedure can be repeated and try to loosen the winding body, and also run a knife along the seams of the ferrite halves. In the end, you will be able to disassemble it, but do not rush, do everything with caution. In my case, even after breaking such a trance, I did not despair, and connected the four pieces of the core with tape. Some glue the cracked slices, but even without that it works just fine, tightly compressed with adhesive tape.

Having disassembled the transformer, remove secondary winding, and in its place we wind 3-4 turns stranded wire, cross section 2.5-4mm2. Suitable for this electrical cable(network). The insulation is first removed, and in its place a heat-shrinkable casing of suitable size is put on. Why heat-shrink tubing? Because she takes less space, regarding cable insulation. Now, we wind four turns, with a branch from the third. The voltage on the last turn will be approximately 9.0-10.5V. All that remains is to put the transformer back together and remove the leads, as can be seen in the photographs.

It's time to work on the body of the electric burner. For this we need an aluminum furniture leg. Yes, yes, furniture again! It is very cheap (less than a dollar), but most importantly it is made of 1 mm thick aluminum. Thus, the case will serve as a heat sink for transistors, which get very hot. Square leg height =100mm. The issue is also being resolved front panel. To do this, we disassemble the leg and leave a plastic plug with which we cut off a part - so that all the components of the product fit. Further, the radiator for transistor switches is also aluminum.

I used a 5mm thick plate radiator. It already had threaded holes, which I later used. But if you find a copper plate, it will definitely serve as a better heat sink. Also, you can use any other radiator suitable size. In addition to this radiator, I connected an aluminum U-shaped profile– you guessed it, it’s also furniture, which fits snugly into the square profile of the body.

The radiator must be in close contact with the body! This way, the heat will be distributed evenly, with greater efficiency, throughout the entire body, without requiring bulky radiators. The U-shaped profile is connected to the radiator plate with a small gap (2-3 mm) through small washers and then we screw this “sandwich” to the plate included in the impulse generator kit. Transistors and the board must be attached through an insulator, also from the UPS. It is preferable to ground the burner housing.

Don’t forget, the device is connected to a mains voltage of 220V, so we take all safety measures during assembly and commissioning!

Now, we drill holes in the plastic front panel for the electric burner operating mode switch - for wires and for LEDs red And yellow glow. We connect the LEDs with limiting resistors with hot glue, as can be seen in the photo.

Next, twist the switch and solder all the wires together (see figure). Switch – P2T-21(Soviet production, maximum switching power up to 660 W with active load). It is necessary to use the most powerful toggle switch possible, otherwise the contacts will overheat! Maximum power electric burner reaches 70 watts.

To the body, as legs (anti-slip), we glue self-adhesive cork or silicone (available from glaziers and furniture makers). As a handle, I used a ready-made handle from a burner industrial production. And if you make it yourself, then a handle from a burnt soldering iron will do. Or we cut it out of textolite, wood with a fluoroplastic tip of suitable thickness. Fastening for nichrome - the terminals of electrical blocks are just suitable for these purposes.

I found nichrome for tips with a diameter of 0.8-1.5 mm on the radio market. Suitable for different heating devices. It must be bent as in the photographs and the tip flattened with a hammer. I made two types of tips: one from millimeter nichrome - for burning and cutting, the other from one and a half millimeter, for rougher work. Accordingly, the second one will effectively heat in a more powerful operating mode of the device (turbo).

The wire for the electric burner must be selected with a large cross-section and the most flexible. Otherwise it will get warm. Naturally, the electric burner will work intermittently, approximately 15-30 minutes.

Firstly, the efficiency is very low, which leads to large heat losses. And secondly, the handle will heat up, which forces you to work with it cyclically. For more convenient use, I advise you to adapt a push-button pedal (from sewing machine or from some machine) or push button switch food, etc. I did not make additional holes in the case or radiator for heat removal. This is at your discretion, depending on the radiator used.

The device is very easy to manufacture, thanks to ready-made solutions to assemble it. It can be made by any beginner with minimal electronics skills. The main thing is to follow safety rules when working with it. After all, the tip temperature reaches 500-600 degrees.

If you make an electric burner for a child, then the presence of an adult when working with it is mandatory. I hope it brings joy and creative success! ).

Discuss the article ELECTRIC BURNER

Today, many people, both adults and children, want to burn wood. This type of hobby even has a name - pyrography. Since ancient times there has been this type art, its essence lies in depicting drawings on wood on a hard surface so as to capture the picture on long time. To do this, use a very hot object that will melt the surface, thereby leaving marks.

What materials should be used? Wood is chosen as the basis for the future image, since it is one of the most pliable, cheapest and most available materials for burning.

Undoubtedly, every person at least once saw the fruits of pyrography live. Translated, this word means image using fire. It looks really fascinating.

Surely every person has been surprised more than once by the beauty of drawings and patterns on wood. Wood burning, like drawing, is painstaking and great work. Those who create with the “help of fire,” like sculptors and artists, are very receptive to the world around them, because this is the main condition for creating masterpieces. A masterpiece, in this case, is not just to depict someone’s face or an element of nature, but to convey every feature, even the smallest detail, to display the mood, the expression of the eyes (if it is a person). And all this on one small board.

There are several types of burning

Using a store-bought device (meaning purchased in a store developed by a company).
- Using homemade wood burners (that is, the element that you make from your own materials).
- Using the sun and a lens. This method is used by many children who have nothing to do in the sun, but it was used by ancient people to get a fire or transmit any information to other tribes using a drawing on the bark.

Today, the most relevant thing is a homemade wood burner, since the sun is not always there, and we are not ancient people in a hopeless situation. And when buying a new device you will have to spend a considerable amount of money.

To make it yourself, you need to have an understanding of the structure of any store-bought analogue. With the right approach, you can develop more functional and high-quality wood burners.

What does the store element consist of?

We can only consider it externally. A inner part can be seen in the drawing. The wood burner diagram is shown in the photo below.

By the way, stores most often sell power tools. Therefore, it is worth looking at the main parts, including the transformer for the wood burner. Also, for an expanded understanding of these elements, you should pay attention to the operating instructions. The main parts and the material from which they are made will definitely be specified there.

How to make a wood burner with your own hands?

To implement this idea, you need to use a lot of ingenuity and perseverance, since this is not the easiest task, and the scheme is very confusing. During manufacturing, you will have to use a variety of equipment that is not commercially available.

What will you need for this?

It all depends on what kind of wood burners you decide to make. The only thing that will be useful in any case is nichrome wire. The next required spare parts are a battery and a wire. The battery is preferably a rechargeable type, since constant use of the device will use up a lot of regular batteries, which can significantly hit your pocket.

There are also requirements for the wire. Good wire is a guarantee of your safety, so you should approach this issue very responsibly.

Where can I find a diagram for development?

You can develop the scheme yourself. In our article you can find a lot various types schemes - from the most elementary to quite complex. All these inventions were designed to suit the nature of the developer, naturally. You can easily choose any of the schemes and work according to it.

It is worth recalling that each person is an individual, which means that each has his own character and his own requirements for life. In this case, it’s worth remembering this, looking through the large number of proposed scheme options and creating your own, even if it is a little more complicated and more demanding than the others.

Naturally, it will be easier to implement your idea for people who are closely familiar with physical laws, and especially with electrical circuits. If you don’t understand this, no problem, you can find information about graphical representations of circuits, understand the images and find out what is what in reality.

Where should I start?

You need to start by modeling the burner first in your head and then on paper. When you have clearly defined ideas, you can start looking for parts for the device. This will not take much time, since everyone has the basic spare parts in the house. Of course, it will be more difficult if you choose a pyrograph with the ability to change attachments and change the temperature.

How to make the simplest burner?

Surely many don't large quantity time to do difficult option burner. Therefore, let's consider the hiking option.
To make the device we will need:

Needle from a medical syringe;
- one sewing needle;
- 9 Volt rechargeable battery;
- double wire.

The needle should be given more attention, since the quality of your masterpieces in the future will depend on its quality. It is desirable that it be sharp and thin. During operation, it is the needle from under the syringe that will heat up red-hot. The second one will barely touch it. This will cause resistance and will cause the needle to warm up.

A cap from syringe needle, as well as a sewing needle (with thread). It is necessary to pierce the cap with a needle and stretch the thread to the end - so that the needle fits tightly to the cap. To secure it, wrap it with the rest of the thread. In this case, the needle should extend beyond the cap and be positioned strictly parallel to it.

Next, let's return to the syringe part. The cone-shaped cap is of no use, so it must be eliminated. We wind this needle to the opposite side of the cap with another thread, parallel to the sewing needle. Now you need to slightly bend the tip of the needle so that its tip touches sewing needle. As was said above - than smaller area contact between games - the better it is for the speed of warming up.

Next step

Next, you need to take a high-quality double wire. It must be cleaned on both sides and two holes made in the cap to bring the wire out. Having done this, you need to connect each wire to the corresponding needle. It is advisable to screw the wires very tightly, since the quality of the current flow depends on this.

For safety and quality, it is necessary to finally secure the wire (including threads) with insulating tape.

At the end of the work, you need to use an unnecessary button (preferably from an old tape recorder) and a rechargeable battery. The main thing is not to confuse the polarity, otherwise homemade apparatus will not heat up (or rather, its tip).

All is ready! All that remains is to try out the made device in operation.

Summarizing

It is worth noting that now burning is not only a way of spending time, but also a way of earning money. The demand for burning portraits and landscapes is increasing every day. Now this activity competes with wood carving. Wood carving was originally created to diversify the interior of ancient houses of the nineteenth and twentieth centuries. After all, when there was no beautiful furniture in stores, they created it themselves. Recently we started trying to use burning on furniture instead of wood carving. This solution will make the interior not only beautiful, but also unique.

The price depends on the number of strokes required and the quality requirements of the work.

In fact, you can make any wood burners in a short time. A drawn sketch or drawing will greatly simplify the assembly or even the creation of your own model of the device.

It doesn’t matter how complex the model is; the most important thing in this device is the correctness of the tip. This is what can affect the quality of your future paintings. The wood burner performs patterns very accurately, so the image can be of any degree of complexity. By the way, as shown in the previous photographs, the shape of the tip for this electrical appliance can be changed depending on the complexity of the work.

So, we found out how to make an electric wood burner with your own hands.

Not only many teenagers, but also adults enjoy wood burning. Wood makes beautiful souvenirs that can be given as gifts. New Year, birthday or just any memorable date. Are in particular demand wooden boards with a drawing that you make yourself.

We suggest watching a video that will help you make a wood burner at home.

For a wood burner we will need:
- car battery 12 volts, but if there is electricity in the room, then the battery can simply be replaced with a cord with a plug that will connect to the network;
- electrical tape;
- small boards for pens;
- fastenings from an old 220 volt relay;
- 2 aluminum wires with insulation, approximately 2 mm in diameter;
- a thick wire connected to the output;
- spiral for burning, 0.7 mm thick.

I would like to immediately note that at 12 volts the tip burns out very quickly and in order to prevent it from burning out, we simply lower the temperature. The easiest way is to make a rheostat from the same spiral.

We wrap the rheostat around a screwdriver like a spring and simply connect it to the battery. Be sure to make a reliable connection.

We connect one end of the cable that comes from the burner to the battery, and the other end to the rheostat.

To turn on the burning device, we connect a rheostat to the second terminal of the battery. Be sure to attach the rheostat with a clothespin.

We attach wires to the relay that will run along the wooden handle. We wrap the entire structure with electrical tape. We attach a two-core cable to the wiring, one end of which will go to the battery, and the other to the rheostat.

) presents a wide range of devices for burning (in common parlance - “burners”, in foreign language - “pyrographs”). Standard questions from buyers: which device is better? what to choose for a 12 year old child? what to choose for yourself, an adult who has decided to take up wood burning?

Watch this video review and choose the device you like. All burners have their own characteristics and capabilities.

Types of burners, their features and differences

Soldering iron type burners "QIDDYCOME"

Burner "PATTERN-PDV"

Burning station "JLT-07B"

Burners "PATTERN-1" and "ELM"

Burner "ETUDE"

Summary

1. There are 2 types of burning devices: with an incandescent loop and a “soldering iron” type.

2. Soldering iron-type devices rarely burn out heating elements located inside the handle.

3. Soldering iron type devices do not have a tip heating temperature regulator; The thickness of the burning line is determined by the time and force of pressure.

4. For devices with an incandescent loop, the nichrome loop periodically burns out and requires replacement. With careful handling, the loop can last quite a long time.

5. For a professional-class device Uzor-PDV, replacing the incandescent loop is simply done with screws. For amateur-class devices Uzor-1, Vyaz and Etude, the filament loop is replaced by re-soldering (at home by a full-time or freelance man 12 years of age or older who owns a soldering iron). The loop is re-soldered using refractory solder. Resoldering of the contact holder with the incandescent loop is carried out with ordinary solder.

What inexpensive burning device should I buy for a boy or girl aged 5-12 years?

If you do not have the opportunity to occasionally re-solder the incandescent loop yourself at home, buy a Taiwanese QIDDYCOME “soldering iron” type device of your choice.

Many people today, both adults and children, love wood burning. This hobby option even has its own name - pyrography. This type of art appeared quite a long time ago, and its essence lies in depicting drawings on hard surfaces of wood so as to capture the picture for a long time. To do this, you need a heated object that can melt the surface and leave marks.

What materials are needed? Wood is suitable as a base for the future image, since this material is one of the most inexpensive and amenable to burning.

Undoubtedly, every person has seen the result of pyrography at least once in his life. This word is translated as “image using fire.” The drawings look really very original.

Like drawing, wood burning is quite a voluminous and painstaking work. To create a masterpiece of pyrography, it is not enough to depict an element or someone's face. It is necessary to convey every touch, even the most insignificant, reflecting the expression of the eyes and mood.

How to make a burner yourself?

To create a burner with your own hands, you will need quick wits and perseverance, since this is not the easiest thing to do, and the diagram is quite confusing. During production, you will have to use different equipment that is not commercially available.

What do we need?

List necessary items depends on what kind of wood burner you want to make. The only thing you will need in any case is this nichrome thread. The next required spare parts are a wire and a battery. It’s good if the battery is rechargeable, since constant use of the device will consume a lot simple batteries- it will hit you in the pocket.

There are also some requirements for the wire. A good wire will guarantee your safety, so approach the issue with all responsibility.

Where can I get the diagram?

You can develop the scheme yourself. Our article also presents several different schemes - from elementary to complex. All inventions were calculated according to the developer’s requirements, and you can choose the appropriate option.

It should be noted that each person is individual and has his own character and requirements. There are a lot of options for schemes, so you can try to make your own, even if it is more complex and demanding than those presented.

Of course, it will be easier to implement your own scheme for those people who are familiar with the laws of physics and who have encountered electrical circuits. If you don’t understand this, find information and images of circuits, understand them and find out what works and how.

Where to begin?

You should always start by modeling the burner in your head, and then you need to transfer the drawing to paper. Once you have clear ideas, you can start looking for components. This will take a little time, since the basic parts are available in almost any home. If you need a pyrograph with interchangeable attachments and temperature changes, things get more complicated.

How to make a simple burner?

Few people have enough time to create a complex burner, so let's consider a simple option.

Materials

To assemble this device you will need the following:

• sewing needle;
• needle from a medical syringe;
• double wire.

The needle is very important as its quality will affect the quality of your masterpieces. It is better to choose a thin and sharp needle. The needle from the syringe will heat up to red during operation, and the sewing needle will lightly touch it - this will cause resistance and help warm up the needle.

Build process

To make a burner you will need a syringe needle cap and a sewing needle with thread. You need to pierce the cap with a needle and pull the thread to the end so that the needle rests on the cap. To secure it, wrap it with the rest of the thread, and the needle should go beyond the cap and be placed parallel to it.

Let's return to the syringe part. We don't need the cone-shaped cap - we remove it. We wind the needle to the opposite part of the cap with another thread and a sewing needle. Now slightly bend the tip of the needle so that its tip barely touches the sewing needle. As we said, the smaller the contact area, the faster the burner will heat up.

Nutrition

We take a good double wire - it should be stripped on both sides and two holes should be made in the cap to bring the wire out. After this, connect each wire to the needles - screw them as tightly as possible, since the quality of current flow will depend on this.

For quality and safety, finally secure the wire with electrical tape.

Finally, use an unnecessary button, for example, from an old tape recorder, and a battery. The main thing is not to reverse the polarity, otherwise the device will not warm up.

Let's sum it up

It should be noted that burning today is not just a hobby, but can become a way to earn money. Every day the demand for burning landscapes and portraits is increasing - this activity competes with wood carving. Initially, it was created to diversify the interiors of ancient houses of the 19-20 centuries. When you couldn't buy it in stores beautiful furniture, it had to be created with your own hands.

In fact, you can make any wood burners in as soon as possible. A drawn drawing or sketch will simplify the assembly process and creation of the device.

It doesn't matter how complex your device is - the main thing is to get the tip right. The quality of all created paintings depends on it. If the burner draws patterns on wood as accurately as possible, you will be able to draw images of any complexity.
