Do-it-yourself plasma pen for wood burning

Hello dear readers andthe inhabitants of our site!
In the past article An apparatus for cutting paper using an electric arc has been described.

This time, the author of the YouTube channel “NightHawkInLight” will tell you how you can make a handle for burning on a tree on the same principle.

Materials
- Brass tube, wire
— 
— 
— 
— 
- Wires, heat shrink tube
- solder
- A piece of board, or plywood.

Instruments, used by the author.
- Screwdriver, tweezers, nippers

Manufacturing process.
So, the author will use just such a plasma lighter with a battery.

Its almost complete analogue is such an option with.
Do-it-yourself plasma pen for wood burning

The author begins by extracting an electronics unit from the housing. He does this so that, if necessary, everything can be returned to its original place.

The pins are pushed with an awl and pulled out to release the top of the lighter.



Then the ceramic part holding the electrodes is also removed.



Then electronics again placed in the housing, its operation is checked, and the screw is tightened.


Established wires are lengthened, soldered, and insulated with a heat shrink tube. It is advisable to use special high-voltage wires.


Holes are drilled in the lid, high-voltage wires are passed through them, and it is replaced. You can fix it either with hot glue, or return the standard pin. Since the power button and the charge connector are located outside, the author selects the first option. Thus, the lighter actually turned into a power supply for the device.


The device of the handle is very simple. The author solders both high-voltage wires, respectively, to two brass rods that are cut to the required length. Also cuts a brass tube with an outer diameter of 4 mm.

Then each brass electrode is bent so that between them there remains a spark gap of about 1-2 mm in width.
All parts are fixed on a wooden plank. Of course, it is advisable to use a plastic tube in the center, but the author did so.



So that the device can work in the plasma torch mode, the brass tube is bent so that the air goes directly to the spark gap. A slight bend in the tube further focuses the air flow on the desired area.


The tube should be long enough and protrude from the back of the handle beyond the boundaries of the wooden rod so that it can then be connected to an air supply.

The author isolates the handle body, putting a heat-shrink tube on it, and heats it with a gas burner.



Without air supply, the device operates in a simple arc mode, and simply breaks the rope with a spark.



The last step is to connect the brass pipe to the air supply. For this, a silicone tube with an inner diameter of 4 mm will be very welcome.

You can use the power of your lungs, or connect to the device an air compressor, which is usually used for aeration of aquariums.

Now you can turn on the air supply, and immediately the difference in the arc becomes visible, it turns into a kind of flame. The rope just burns.




That's all! This device can be wonderful to burn wood.


If the tree is allowed to get charred enough, it starts to conduct electricity, which looks pretty impressive, but is useless from a practical point of view. Therefore, it is better to move in quick passes to get a neat pattern.



And here are the author’s first attempts to draw something. It will take practice.




In conclusion, I want to add here. Here, the case immediately has the shape of a handle, and it will be much easier to make such a plasma burner.

Thanks to the author for the idea of ​​a simple but very interesting tool for burning wood!

Observe safety precautions when working with high voltage!

All good mood, good luck, and interesting ideas!

Sorry lighter, not in the collection. For gas stoves there is a similar device. But for some reason there is written "piezo". Purely "piezo" used to ignite a gas burner.

Is Conder standing after the bridge?

No, there is no skin effect, otherwise it would not need a blow. The author does not touch the surface with electrodes, but keeps them close. It blows hot air from an arc burning near the surface of the wood.

Now, when it is already charred, then it starts to conduct, and the arc “hits” at two points.

Video look who is interested.
Chinese? Is something not being done in China now?

I’m worth 450, it was 400 with a penny of volts, from where, I don’t know.
About the skin effect. Maybe not everyone knows. HF currents flow over the surface of the conductor. I have shown people focus many times. From the output of the transmitter, he passed the RF through his body and lit the bulbs. He made a great impression. But with the wrong choice of frequency, he received a burn of his fingers. In the end, threw these tricks.
I want to add, a lot depends on the resistance of the body. I know cases when 220 people do not smell. Resistance also depends on the emotional state. Also, if you drink vodka, it falls. Salty to eat, also falls.
As for the residual cramp on the Conder, more than 400 volts were bent. 308 could be after rectifying the 220 volt network. Unless the network was overpriced. In some BPs, I came across 450 V input electrolytes, and in some manufacturers do not bother, they put on 400. In Chinese, they often put two in series at 200 V. But this is not entirely correct. We need equalizing resistors, about which they forget or save on resistances.
That's right, the whole point is the energy stored in the Conder. We had some jokes at our factory. Charged the electrolyte to about 300V and threw it. metal melted thin.I indulged the other day with homemade spot welding. Charged the capacitor 680 microfarads only up to 90 volts. When discharged, the knife blade burned to half thickness. The most interesting, charged from a stepper motor, twisted the shaft by hand. The motor 4 is winding, put on each winding along the diode bridge. Charged for 50 seconds.
I thought about it. At the plant, when adjusting color televisions and testing them, there was a stand and 27 kilovolts and 900 microamps were considered normal. 24 watts is obtained by power, if I correctly multiplied. Sometimes, the sucker flew off the second anode of the tube, so for a split second burned the surface of the table. This is despite the fact that the output of the voltage multiplier is 15.625 kilohertz, smoothed by capacitors. I wonder what are the parameters of a small lighter? Is it reflected somewhere?

Gee, what did you want from the input BB Conders?
Usually, discharge resistors are hung on them, but some Chinese save. secret
And why not place electrodes in housings from ballpoint pens, for example? Although wood burning can be implemented much easier! scratch

TDKS will have more current. And here - only a skin can scorch. From the usual piezoelectric element has not yet killed anyone, the current is scanty. In an electronic lighter, just pulses go with great frequency, and so an arc flares up.

I just recently shunned, disassembled the power supply from the laptop, replaced the bold kander at the input, turned it on, it works, it was postponed. Then, after some time, he took it, and as he gasps, right up to his chest the current has reached, it was felt. On the fingers there were points from the contacts, the skin burned out.

Then I measured it on a cander -> 400V swoon
it can throw, depending on which muscles work
Cool thing, but very dangerous, she needs to work carefully. Right here they wrote about the skin effect. Moreover, everyone has their own reaction to electric shock. By the nature of my work, it is often sharaho from TV sets and monitors under 29 kV. Normally, the arm simply reclined, and a friend weighing 100 kg, approximately, from 12 V of the constant, reclined by 2 meters. Whole body.
Be careful, such a lighter generates pulses that repeat at a low frequency, the surface effect does not work.
