Thank you. I'm glad you like it
Use this with a CNC machine. Use the induction heater to create a self sharpening cutting tool. Heat + slow cooling = annealing, (AKA softening of the steel). Heat + fast cooling = hardening. To make cutting tools, steel is first annealed. This processes makes the steel easy(-er...-ish) to cut and grind. Finally, the shaped steel is heated again, and cooled quickly with something like water or oil. This creates the hardness needed to use the shaped steel as a cutting tool.
The simplest cutting tool is just a pointy thing. If a steel rod was ground with one angle to a point, and the point was offset from the center, you would have a potential milling cutter. It just wouldn't last very long with this shape. However, if you could anneal the steel, you could grind it with typical cheap abrasives. If you can harden the steel tip with a repeatable process after grinding, you can create a repeatable cutting/annealing/regrinding/hardening routine (aka the cutting time is programmed and it always keeps the tool sharp).
You would still need a way to feed a long rod through the milling collet and a way to keep up with the z-axis tool depth. Why do this? By far, the most expensive part of machining is cutting tools especially in a professional shop. If you could process your own cutting tools in-situ you could machine anything cheaply. Even if you would normally need to have a special cutting tool, the wrong size/shape tool will still work most of the time. Normally you avoid doing this because of the cost:time ratio. If you change the cost factor you must re-evaluate the ratio. I'm suggesting the creation of "One Tool to Rule Them All."
This channel explain theory behind circuits very good. Other channels just build pcb and share gerbers but without knowing how they work im not interested to their channels.. Thanx for explanation ..
You are one of those first who explaining ZVS operation
PouHa! Ha! Ha!
First video I've seen that explains why the metal heats up, other videos just show it can be done 💯
So that's why we put isolators between transformer's layers, otherwise it will get hot thus more power loss
That's a great video dude
So hard to find videos that go into the theory, subscribed!
Your photo in the notifications list is moving, that's so cool to see !
That was the single best video I could find related to this topic, consider me impressed
Very well explained. Thankyou very much.
Thank you, I am learning from you and also I am learning English and also your language is very good and clear
Good inventory, motivative project, using simple induction phisics.
Good job of explaining how induction heating works.
You answered something no one answered, u r the best
Very helpful video. Thank you so much
Best explanation I've found yet. Awesome video
but before we start make sure that you ""HEAT"" subscribe button :D, Nice explanation as always
Great video.
What if you wanted to add a pot to control the current?
The JLC PCB Cash cupon was only availabe up to 30th May dude......
Btw nice video.
Nice one man... I also studied Electronics Engineering very well explained theory and easier to understand than books
Schematic of your homemade one in the video is different than the one linked on your website. Does it make any difference?
You explain electronics better than anyone else on yt.
Oh, so glad you say that :))))
A DIY induction soldering iron might be an interesting future project. Basically a Metcal for a fraction of the price. (Probably be best to use replacement tips rather than trying to adapt normal tips to induction heating.)
@_____ It would be interesting to compare induction tips to integrated heater tips. Traditionally, induction had a huge advantage since the heat is generated in the tip itself. It is very well possible that integrated heater tips (like what the TS100 uses) has narrowed the gap to the point that induction no longer has that much advantage.
May I know, why your breadboard can withstand such high current flows? Because I remembered that if current greater than 3A maybe some chances to melt the breadboard.
Was about to say this..
Is an old breadboed and is made out of a different plastic ... I had no problems...
@@ELECTRONOOBS okay interesting :) thanks for your effort always make a lot of amazing videos. I really inspire your different microntroller project especially you used the button to control the user interface and menu. I am also your patreon supporter hehe
@@mhzxtal922 thank you very much for your support
Thanks for such a simple and nice explanation!
I love watching great scott you how to mechatronics and db eorkshop
Very good video as always
I hope you will upload a video on howto make an incubator based on
Thanks again for sharing your knowledge !
Fantastic project, dude! Really nice!!! 😃
great work 👏👏👏👏☺☺☺
You telling me after two years since this video is out no one noticed "no fap" when you were shaking the magnet🤣🤣
The circuit diagram was difficult to see on the light green animation. Great video anyway.
Thanks, I'll have that in mind for next video...
good
Theoretically, it can be used as a wireless power supply if i use 2 pancake coils one for TX and another one for RX, right?
Yes
Is there a way to adjust the intensity of the EMF?
I think most people are essentially pulsing the input voltage. I’m hoping there is a more reliable way to adjust the strength of the field for more controlled heating.
what was the difference between the ebay module and the one you built yourself?
The eBay module had more output power...
Now the zero voltage switching model works, but you don't have control over the frequency setting, which is not good
Can one use just this module, power from a 12 volt 7 ampere hour battery and use a 2D coil for a induction cooktop ?
Gracias electronoobs.
¿Podrías hablar sobre la eficiencia o compararlo con cocinas a base de gas butano?
Nice explanation
You are a great teacher!Thanks.Best Video!
I can see this used for a few things in m shop but I don't have any power supplies that can output that much current.
A 12v car battery fed by a charger.. 😎👍
What I don't understand is why does the circuit use a parallel LC circuit, which has high impedance at the resonant frequency. Wouldn't a series LC circuit , with low impedance, allow more current to flow thru the coil? and higher current equals stronger fields
Mine doesn't heat it up like that... what am I doing wrong I have the same chinese ZVS.... O_x I can drive a flyback pretty good with it but when I try with a coil for induction heating it's garbage... any idea why ? I tried many different spirals... 4... 6 ... 8 and 10.... the more spirals the less power it draws but doesn't do much...
Why high voltage (1200V) capacitors are used , when peak voltage shown in oscilloscope was 48V?
can I slap in a bigger resistor if I wanted less induction power
Can You Make A Project That Combine The FingerPrint Door Lock And The KeyPad Door Lock To 1 Door Lock? ,With Admin Menu Maybe??,Please.i want to make it for my house security
You want to make your house less secure?
Thanks for making the video, I'm loving your series on how electronics principes work. Sometimes though, you lose me at particular steps because it assumes prior understanding of electronics. In this video it's the 'flipflop' switching between the two mosfets. I understand that switching is part of making the coils oscillate but I couldn't extract from the schematic *why* the switching happens. You're providing DC power to this circuit, no?
look up the tanner tech video ZVS flyback driver. He does an excellent job explaining the switching effect your enquiring about.
Commercial induction hobs are digitally controlled. A shame there's no open source projects for digitally controlled cookers, it would be much safer and much more useful in general. Any idea where I can find resources?
As I understand it, the commercial induction hobs do a frequency sweep (no clue how that works) and adjust their oscillation frequency to match that of user's desired power output to the workpiece (also no clue how that works, some combination of transistors and chunky inductors/capacitors). Any help appreciated!
Waow nice sharing 👍
Good tutorial. I bought an induction module just like that some time ago. Never got it to work and never spent the time to experiment. Do you have any idea of the range the inductance needs to be in? Maybe that was my problem.
At 1:55 he keeps saying that " there is a current induced in the inductor!" He should correct that as he has an OPEN CIRCUIT and so there could be "no continuous constant current" in the inductor, It is the voltage that can be externally measured depending on THE RATE OF CHANGE OF MAGNETIC FLUX. Also, the oscilloscope probe normally measures VOLTAGE difference and so what he is doing is changing the magnetic flux to induce" a measurable voltage" at the ends of the inductor. In this case of an open-circuited inductor, the relation is Voltage = Number Turns * Rate of change of flux. There is no external current flowing.
If we want to be really accurate in what we say, what happens when a continuous rate of change is suddenly applied, then the rate of change of flux will force and move some of the equally distributed electrons already existing in the copper of the initial electrically neutral inductor to one end of the inductor, creating the electric charge at one end to form the voltage we mentioned. Note that when a sudden rate of change of magnetic flux is applied, to an open-circuited inductor, the movement of electrons is only for a short moment until the ends of the inductor charge up with a DC voltage in case of a continuous constant rate of change of flux, which cannot happen in real life and that is why we normally use AC activities in an inductor, to reach a limit and then keep reversing the action to produce a variable but a continuous rate of change going from a positive to negative passing through a zero rate of change!!!.
So for a constant rate of change of magnetic flux, the output of the inductor will be DC, and then and only when the inductor is loaded there will be a continuous current in the load, but not with an open-circuited inductor............as there will only be a movement of a group of electrons till the end terminals of the inductor do charge up to the voltage produced by the action Force of the (Number of Turns) multiplied by the (Rate of Change of magnetic flux)
Really we can compare the charging of a capacitor to that of charging an inductor as while the capacitor has a number of electrons being moved from one plate to another by an electric field, in an open-circuited inductor one of the ways to move electrons is by using the rate of change of magnetic field.
Many statements in electrical engineering may sound simple, but they could be misleading and it is a case which can give great meaning to what Albert Einstein said,, " You can make an explanation simple, but not any simpler than that!"
Also, the eddy currents in the knife, do not go "back-and-forth" as he described at 03:18 but Eddy Currents flow in LOOPS and SHORT CIRCLES, in the plane of the turns of the original inductor. It is very important to note that the actions in question ( V= N* d( Flux) dt) have VECTOR QUANTITIES with magnitude and directions and one cannot get neither the magnitude nor the direction wrong as the system will not work.
One needs to look at the direction of orientation of the laminations, the orientation of the coils, so the orientation of the electric and magnetic fields, used in Transformers and Motors and generators to get an appreciation of the importance of getting the orientation of the eddy current correct, and it is not a simple statement, " They go to and fro or back and forth! "
Friend, I have a circuit like yours. But when I turn on the power supply it drops from 12 volts to 5 volts and heats up the transistor on the left and doesn't heat up the stylus. What could it be?
Excellent video. I noticed schematic had an inductor in series with + supply but it was not in your circuit or in the eBay unit. What is the purpose of the 3rd inductor?
I imagine how melted and deformed is the breadboard after 1 minute of operation. The ZVS as far i know transfer huge amounts of current between the coil and the tank capacitor, especially if you put metal for heating. The traces of the board are maybe steaming hot, and the plastic is burning.
What is the voltage output on this unit? are the a&b outputs both hot or is one ground?
I have that same module and am using a 24vdc, 1000w, 20amp power supply. The coild is 10-guage solid copper wrapped 7 times. Set to 24vdc, I turn-on the power supply and in about 1 second, the coil gets so hot that the solder holding the terminal on the circuit board melts & the terminal falls off. Any idea of how to correct/fix this problem? Thanks!
nice tutorial, very interesting
Current limitations is necessary for this ZVS circuit??
Excelente la explicación...saludos
Hi. Could you let me know What is the marking of the mosfets used in that Chinese zvs module?
Hi i habe the same zvs and connected it to a 12v car battery. But after turn on the transistors are very hot and i thinl they will be overheated. Is there to much current or the coil to thick? what can false? Please help bevor sonethibg burns out! Thx
Kindly tell me how did you calculated 50 micro Henry of induction coil?
What's the difference between using 2mosfet and using 4 mosfet
more current
Hey bro it is necessary to use ultra fast shottkey diode Or common rectifier diodes would work.
Can anyone tell why three is a series inductor to the centre tap to the coil.
what happens if you increase the diameter of the coil
Is this a zvs induction heating or simple induction heating.
Can i drive this circuit through 12 Volts 5 Amp Bike battery
This type of circuit ruins breadboards...but good video!!!
Thank you for the video :)
Nice video dude
Is it possible to us that with an flat coil (Pancake Coil)?
Como se puede hacer para comprar esa plaqueta y ,si pueden enviarme en castellano el video .
GrA cias MUY ATTE LUIS
At 5:30 your build and schematic are different.
Can it heat copper?
Excelente sir 👌👌👌👌👌
Where is your matching transformer?
no fap .. lmao. btw great video.
Man, would that heat up dental filings if it was held outside your mouth? Or keys in your pocket?! Be careful!
by the way what the use of that banana ?
@9v Battery wow genius
can i have the circuit diagram
I never succeed for this circuit
🔥🔥🔥
Good
"It gets hot very fast, and also very hot"
Great work! Does mu metals get heated faster or not at all?
You really can't wait? Just look at min 5! Mu metals would go slower.
Why you kept saying coil instead of Inductor 😅😅
It makes me feel uncomfortable .😅😅
Sorry...
@@ELECTRONOOBS hey brother there is no need to say sorry. I was just saying that for fun. You are doing so much effort to power the world with spreading knowledge. You are doing so nice work. I really appreciate your work man. Please dont stop keep doing this.♥️

Is possible to use microcontroller to control the temperature and current of metal?
This person needs to be more careful as all the circuit diagrams he showed do not describe the actual circuit he built. So it follows that the explanation of how it works is not what he described.
All his circuit diagrams in this video have a center tap in the tank inductor and so the coil is split in two where the center point is the positive of the power supply. The circuit he built does not have a center-tapped coil and it operates rather differently from what he said.
The non-center tapped coil is not connected to the positive supply but the two other inductors are. Basically what happens is the following, when one Mosfet is on, the inductor in its drain, sink in current and starts storing magnetism, then when this MOSFET is turned off, the stored magnetic field in its drain inductance will cause the drain voltage to shoot very high, and ACTING AS A CURRENT SOURCE it feeds its energy into the parallel tank circuit which can only be activated efficiently if it fed on a current source. Meanwhile, the other Mosfet is a dead short circuit for the other end of the oscillating parallel circuit.
While this is occurring the other short-circuited monster will connect the tank circuit to earth and also be charging up the second inductor to repeat the other half of the cycle.
The circuit he built is a beautiful circuit as the drain of the Mosfet acts as a voltage source when on and as a current source when off! As an oscillator it is remarkable how the current source effect matches beautifully into the impedance of the parallel circuit.
hi brother can you make a alexa
relay robot from arduino mega for more relay channel it was you will use arduino mega ....can you help me to make your big fan.
please help me buld a project

The wavelength of the coil is a red-herring and has zero to do with the resonance. Wavelength only applies to Antenna in RF systems. The resonance is given by fo = 1/(2*pi*sqrt(LC)). Don is purposely giving that bogus information so that only people who truly understand resonance will get it.

Never mind highlighting the simple fact that's directly inspired from Vladi Mazzilli who actually worked on Tesla Coils using Flyback Transformers, refering to his circuit as a "Royer ZVS", to top it all... This is sad & pathetic.
