- Assembly process
Pyrography, or wood burning, is a fascinating, interesting hobby. It is mastered by those who love art. The writings that first mention fire-scorched patterns date back to 700 BC. e. Burning apparatus was invented at the beginning of the 20th century. The first devices were made from a glass container, supplemented by two rubber tubes. At the end of one of the tubes was attached a rubber ball for pumping air, at the end of the other there was a platinum tip connected to the handle.
In the middle of the 20th century, a new type of electric burner appeared, which became the prototype modern apparatus. The original kind of applied art became available to children.
The design has undergone significant changes since then. Manufacturers install a power regulator. With it, you can smoothly adjust the temperature of the working needle. This allows you to apply a pattern on any material at hand. On sale you can find models with large quantity nozzles. Due to different-sized nibs, it is possible to form strokes different size, to give the picture volume.
Despite a sufficient choice among factory devices, many craftsmen want to make a wood burner with their own hands. Mostly experienced artists resort to this..
Often problems are found on the part of the built-in transformer, you have to solve the problem yourself.
Some masters want to supplement the existing simple burner with a special device with which you can adjust the degree of heating of the needle. The article provided practical guide on assembling a mini-burner for wood from improvised means.
Development of an electrical circuit
When assembling a homemade burner, you must have knowledge in the field of radio electronics. This will allow you to develop an electrical circuit. If there are no skills in this area, you can use the scheme below.
The scheme can be simple or quite complex, designed according to the requirements of the developer. The task is to choose the most acceptable option, to implement it in practice.
Preparatory work
Before you make a burner, you need to plan the process, collect the necessary materials, fixtures. The set of components depends on what type of device is planned to be made.. If you need a burner with temperature control, you will have to find a dimmer, dimmer, or a mechanism similar in functional direction. You also need to prepare:
- sewing needle;
- needle removable from the syringe;
- power unit;
- soldering device.
To work, you need to take an old charger from mobile phone. Good for a homemade burner fit block power from the iPhone. Its output voltage is 5.1 V and 2 A. H the more powerful the charger or battery pack, the better . If there is no such device, you can use a charger for a screwdriver or other similar compact tool that does not work or is not used due to uselessness. You also need to find on the farm or buy in the store a barbecue skewer, thread high strength, flux, solder.
The needle is one of the main elements of a homemade wood burner. Her choice should be approached responsibly. It depends on this detail how sophisticated the ornament will be, a miniature silhouette applied to wooden surface. Recommendedgive preference to a thin and sharp needle. A good option- medical needle. She will heat up maximum temperature heat evenly sewing needle, which will burn the pattern on the material being processed.
Assembly process
First you need to take round pliers or locksmith pliers. With their help, the nose of a medical needle is bitten off. Then, strictly parallel, two needles are attached to a barbecue skewer, fixed with a strong thread. End sewing needle bent gently until it lightly touches the tip of the medical needle.
Then you need to connect the wires from charger to the needles. Polarity does not matter, wires can be connected arbitrarily.
In order for the electric burner to serve for a long time and reliably, the joints must be properly processed. To do this, a small amount of floss is applied to them, then they are tinned.
The wires for the burner are soldered alternately, attached to wooden skewers, fixed with threads. Excess protruding ends of the skewers are cut off. For greater reliability, the threads can be treated with superglue, protected with a heat shrink tube. After this stage, the device is ready, it can be used for its intended purpose.
The figure shows an example of a burner.
The principle of operation of the device does not differ from the principle of operation of the factory apparatus. Despite the fact that charging has only 2 A and 5.1 V, at the time of filing electric current the thin-walled hollow needle from the syringe heats up intensively, transfers heat to the sewing needle. The burner is compact, in practice it shows great job, allows you to apply strokes with a thickness of 10 mm to a wooden surface.
To better understand the assembly process, you can watch the video.
A portable electronic burner is a device for drawing a pattern on a certain type of material (wood, cardboard, paper, plywood, fabric). The product is widely used in the field of amateur pyrography, so this device is very popular not only among professional artists, but also among private fans of burning pictures.
To do homemade burner do-it-yourself will need minimum set building blocks and tools that you can use at home or purchase at your local hardware store.
Preparation of materials for manufacturing
To make a home burner, you must have a minimum set of tools and accessories.
In order to make a pyrograph you will need:
- Wooden bead 10 cm.
- Adhesive tape or duct tape.
- The electronic unit is not less than 5 Volts 2A.
- Nichrome thread.
- Soldering iron.
- Electric drill with a suitable drill.
- Flux for soldering.
- Solder - tin.
The manufacturing process begins with the preparation of all tools and the right materials. First you need to find a nichrome thread, which can be sold at any hardware store. In the absence of a thread on sale, the material can be obtained from an old electric soldering iron.
You will need to disassemble the heating part of the appliance. The nichrome filament is located on the "sting" of the soldering iron under the metal casing and can be easily removed by winding without the use of third-party tools.
How to make a mini burner?
1. Making a holder where the burning needle is inserted.
The holder can be made from ordinary wooden glazing bead the length of which is selected individually. On average, 10 sentiments are enough. Inside the handle you will need to make a hole for the wire. It is possible to carry out the procedure using an electric drill or a screwdriver.
The drill should be selected strictly according to the thickness of the wire. At the end of the glazing bead, it is necessary to make small expansion for the conclusions of the ends of the wires to which the needle of their nichrome wire will be fixed.
2. Connecting the electronic unit to the needle
A homemade burner is powered by an electronic unit of 5 volts with a power of at least 2 amperes. As an electric unit, a regular phone charger with desired characteristics. To connect, make a branching of a two-wire wire, divide it into 2 separate ones. The ends are passed through a previously made hole in the handle and brought out.
3. Soldering the needle to the wires
The nichrome needle must be soldered at the ends to the output wires. Each separate end is soldered to a separate wire. For solder, flux should be used, as nichrome material is rather difficult to solder. The size of the needle must be at least 5 centimeters, otherwise the burner will not warm up the thread enough and, accordingly, its performance will deteriorate.
4. Insulating the holder with electrical tape
You can make insulation with electrical tape or adhesive tape. The holder of the burner is wrapped in 3-5 layers and is tightly crimped in the hands so that the tape sticks to the tape with the highest quality. wooden base. During gluing, make sure that the tape does not get on the needle.
5. Testing the burner
To test the burner, you must connect the electronic unit to a 220 volt network, after which you can observe reddening of the needle thread within a few seconds. The device should be tested on any wooden surface.

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 species art, its essence lies in the image of drawings on wood on a solid 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 traces.
What materials should be used? In particular, wood is chosen as the basis for the future image, since it is one of the most malleable, cheap and most available materials for burning out.
Undoubtedly, every person at least once, but still saw the fruits of pyrography live. In translation, this word means an image with the help of fire. Looks really bewitching.
Surely every person had to be surprised more than once by the beauty of drawings and patterns on wood. Wood burning, like drawing, is painstaking and hard 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 line, 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
With the help of a store device (meaning bought in a store for the development of any company).
- Using homemade wood burners (that is, the element that you make from your materials).
- With the help of the sun and lenses. 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 transfer any information to other tribes using a pattern on the bark.
Today, the most relevant is a homemade wood burner, since the sun is not always there, and we are not ancient people in 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 idea about the device of any store analogue. At right approach it is possible to develop more functional and high-quality wood burners.
What is the shop element made of?
We can only see it externally. And the inside can be seen in the drawing. The scheme of the burner for wood is shown below in the photo.
By the way, most stores sell power tools. Therefore, it is worth looking at the main details, including the transformer for the wood burner. Also, for an extended concept of these elements, you should pay attention to the instruction manual. The main details and the material from which they are made will definitely be spelled out there.
How to make a wood burner with your own hands?
To implement this idea, it is necessary to apply a lot of ingenuity and perseverance, since this is not the easiest thing to do, and the scheme is very intricate. During manufacture, you will have to use a variety of equipment that is not available in the usual sale.
What will be needed for this?
It all depends on what kind of wood burners you decide to make. The only thing that is useful in any case is nichrome wire. The next required parts are the battery and wire. The battery is preferably of a rechargeable type, since with constant work with the device a lot of ordinary batteries will be used up, which can significantly hit your pocket.
There are also requirements for the wire. A good wire is a guarantee of your safety, so you should approach this issue very responsibly.
Where can I find a development schema?
The scheme can be developed by yourself. In our article you can find a lot various kinds schemes - from the most elementary to quite complex. All these inventions were designed for the nature of the developer, of course. You can easily choose any of the schemes and work on it.
It is worth recalling that each person is an individual, which means that everyone has his own character and his own requirements for life. In this case, it is worth remembering this, looking through a large number of proposed schemes and creating your own, even if it is a little more complicated and demanding than the rest.
Naturally, it will be easier to fulfill your idea for people who are closely familiar with physical laws, and especially with electrical circuits. If you do not understand this - no problem, you can find information about the graphical representation of the circuits, deal with the images and find out what is what in reality.
Where to start?
You need to start by modeling the burner, first in your head, and then on paper. When there are clearly defined ideas, you can start looking for parts for the device. It will not take so much time, since everyone has the main spare parts in the house. Of course, it will be more difficult if you choose a pyrograph with the ability to change nozzles and change the temperature.
How to make the easiest burner?
Probably not many a large number time to do difficult option burner. So let's take a look at the hike.
To make the device, we 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 will be the needle from under the syringe that will heat up red-hot. The second will barely touch it. This will cause resistance and will help warm up the needle.
A cap from syringe needle, as well as a sewing needle (with a threaded thread). It is necessary to pierce the cap with a needle and stretch the thread to the end - so that the needle fits snugly against 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 located strictly parallel to it.
Now back to the syringe part. The cone-shaped cap is useless, so it must be eliminated. We fasten 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 it touches the sewing needle with its tip. As stated above, than less area contact between games - the better it is for warm-up speed.
Next step
Next, you need to take a high-quality double wire. It must be stripped from both sides and two holes must be 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 conduction depends on this.
For safety and quality, it is necessary to finally secure the wire (including threads) with electrical tape.
At the end of the work, it is necessary 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 (more precisely, its tip).
Everything is ready! It remains only to test the device in operation.
Summarizing
It is worth noting that now burning out is not only a form of spending time, but also a way to earn money. Every day the demand for burning portraits and landscapes is increasing. Now this occupation competes with woodcarving. Woodcarving was originally created to diversify the interior of old houses of the nineteenth and twentieth centuries. After all, when the stores were not beautiful furniture, they created it themselves. Recently they began to try to use wood burning on furniture instead of woodcarving. This decision will make the interior not only beautiful, but also unique.
The price depends on the number of necessary strokes and the requirements for the quality of 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 complicated its model will be, 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 burner performs a pattern on wood very accurately, so the image can be of any degree of complexity. By the way, as shown in the previous photos, the shape of the tip for this electrical appliance can be changed depending on the complexity of the work.
So, we figured out how to make an electric wood burner with our own hands.
Why a homemade burner? There are many domestic and imported models of electric burners for wood on sale: Orbita, Uzor, Elm (ours), Stayer, Qiddycome (Chinese) and others. But lovers artistic painting with a hardened needle on wood are not always satisfied with this available choice.
Domestic devices usually have only one needle, imported ones have from 4 to 21 nozzles with different needles, but suffer from fragility. And you can't always buy desired device in the right place in right time. Here we will talk about the experience of manufacturing by one Siberian enthusiast, amateur, a good-quality home-made electric burner for wood with 39 (!) Needles (see photo). We will conduct, so to speak, a master class on his behalf.
First of all, we set three basic requirements for the design:
1. Sufficiently large capacity of the power supply unit, allowing the use of needles of large sections.
2. Possibility of step voltage adjustment for working with needles different sections and smooth adjustment to change the temperature of the needles in a wide range.
3. Convenient change of working needles.
Simple circuit diagram device is shown in the figure. 
Now let's move on to the process of its manufacture.
We take any power transformer of at least 200 W (other characteristics are insignificant), for example, OSM 380/36V (250 kW). At lower power, the transformer will overheat during operation with needles of large cross sections. Completely remove the secondary (top) winding. The primary (network) remains in place.
We rewind the secondary winding: one or two layers of flexible insulated wire section 6 mm 2 (for example, PV-3). You should first calculate the number of turns per 1 V of the output voltage (by selection: wind a few turns, turn on the transformer in the network and measure the output voltage).
Let, for example, it turned out to be 4 turns per 1 V. Having determined the value of 2 V for the lower limit of the output voltage, we wind 8 turns first, and then we make taps after every two turns. This will give a resolution of 0.5 V for step adjustment. To ensure a resolution of 0.25 V, add another turn (in the diagram, the top tap is 0.25 V).
In addition to stepwise, we also use continuous adjustment of the output voltage by inserting an alternating current into the primary winding circuit wirewound resistor PPB-25 100 Ω (on the diagram - R1).
Due to the high power of the device, we will abandon the male-female connector, and securely connect the working handle with the needle to the body with M6 galvanized bolts. We will equip the taps and ends of the secondary winding with tinned copper lugs 6/6.
Working with needles of large cross-sections requires a current of at least 30 A. Therefore, the cross-section of the wires of the operating handle must be at least 4 mm². You can take two cores with rubber insulation from a KG 4x4 cable (vinyl insulation of a wire of the same cross section does not provide it with the necessary flexibility).
We turn the handle on lathe from ebonite. We firmly insert a fluoroplastic plug with two brass rods into the front end of the handle for attaching the working needle (see photo). These rods fit snugly into the holes drilled in the cork. At the ends of the rods, recesses of 8-10 mm are drilled. Tinned contacts are pressed into the recesses inside the handle. A needle is attached to the outer recesses. M4 screws are suitable for clamping the needle.
Anything can be used as a case, you just need to remember about safety. Very good, for example, is the case from a megohmmeter of the last century: it is fantastically strong and durable.
If you like crafts, then you are probably familiar with such a direction as decorative wood burning. This article describes how you can quickly and easily assemble an excellent wood burner from “improvised” tools, with adjustable heating wire incandescent temperature. The advantage of the described version of the burner is its simplicity, safety and ease of use.
Scheme of a wood burner:
If you need an inexpensive but very convenient and reliable wood burner, then pay your attention to Figure No. 1.
Figure No. 1 - Wood burner scheme R1 - 1.2 MΩ
R3 - 27 kOhm
C1 - 27nF or 273nF / 300V
C2 - 22nF or 223nF / 300V
C3 - 47nF or 473nF / 300V
FU1 - Fuse 0.5 - 1.5 A
VS1 - Dinistor DB3 / 30 V
TP1 - Step-down transformer 220/3 ... 8 V Current depending on the load (nichrome wire resistance).
The operation of the wood burner scheme and its settings:
To make such a scheme is within the power of even a novice radio amateur or home master, primitive skills are needed to be able to solder and set up circuits (if all the elements are selected adequately and the circuit is assembled correctly, it will immediately work as it should). However, a few subtleties should be highlighted:
1) I draw your attention to the fact that the adjustment of the output voltage of the transformer TP1 (and hence the incandescent temperature of the nichrome wire) is carried out according to the primary winding, do not be confused by this innovation! Since the scheme is taken as a basis, you should understand that for any heating element(in this case, a piece of nichrome wire) the shape and quality of the sinusoid is not important.
2) However, I draw your attention to the fact that secondary winding the transformer must withstand the current consumed by the nichrome wire (you can easily calculate it by).
3) You should also use thick wires leading to the handle of the wood burner, and well insulated, not following the rules of electrical safety when assembling or using the device can lead to injury!!!
Nichrome wire holder for wood burner:
Surely, it will not be difficult for you to assemble the power supply for the burner, but what if you do not have a convenient holding handle (electrode)? I offer you a very simple but very convenient option handles. You will need a thick wire, a dielectric (or wooden) handle from an old burned-out soldering iron, a piece of textolite or carbolite or other dielectric heat-resistant material, electrical tape, nichrome wire (you can bite off a piece from an incandescent spiral for an electric stove) Figure No. 2, and electrical terminals Figure No. 3 .
Figure #2 - Necessary materials for burner handle 
Figure No. 3 - Wiring terminals You need to pull the terminals out of the insulation and screw them to the textolite as shown in Figure No. 4.5.
Figure No. 4 - Assembly of the handle 
Figure No. 5 - Explanation of how to screw the terminals correctly Then you just have to tape (or attach with a plastic tie or thread) the wire to the textolite pad and to the terminals (the ends of the wire must be soldered) and press it into wooden handle drawing number 6.
Figure No. 6 - Wood burner handle It is a pleasure to work with such a wood burner because, firstly, you have a convenient handle in which you can quickly and easily replace a burned-out nichrome wire, since it is screwed to the terminals, unlike simple burners. Secondly, it is possible to adjust the temperature of the incandescent wire (Figure No. 7), which is quite important when working with various kinds tree varieties.
Figure number 7 - Hot nichrome wire (Explanation to figure No. 7: my version of the handle has a special tip that will be quite difficult for you to reproduce, so I offer you a simpler version with terminals)
And thirdly, the assembly of such a burner is relatively simple and not expensive. The only thing that will be difficult for you to choose is a step-down transformer, since, despite the low voltage (3-8 Volts, depending on your needs), the secondary winding must be designed for high current (from 3 Amperes).
When all the details of the wood burner are collected by you, you just have to shove it all into a neat case and start blurting out various kinds of pictures and works of art (figure No. 8).
Figure No. 8 - Wood burner ( appearance) and an image burned on a tree. P.S.: I tried to clearly show and describe not tricky tips. I hope that at least something will be useful to you. But this is not all that is possible to invent, so go ahead and study the site
