Wow. That hand drawn circuit diagram is an incredibly beautiful thing. A piece of art. Congratulations!
Thanks ;-)
I learned to draw electronic circuits when there where no computers. I still draw mostly by hand. Drawing a circuit by hand gives you a better understanding of it. I encourage my children to write everything down. It's also very good for developing eye hand coordination.
Hey GS, you call your VCCs as constant current source. Aren't they voltage sources?
+ElectroBOOM They are voltage sources. But the inductor will act as a constant current source.
DAAAAYUMMM, that hurts
ElectroBOOM and GreatScott! two of my favourite electronics youtubers in the comment section of the same video!
I also wanted to ask you about that ... what do you mean by constant current source ?, aren't they just a high-frequency choke to prevent oscillations from coupling back to the supply
OMG THE CLASH OF THE TITANS!!
I built this circuit and would like to share some details that will help you .
1) Select polypropylene capacitors for lowest loss. It is bettter to use many smaller capacitors in parallel rather than a few bigger ones.
2) The circulating current in the tank circuit is very high; it is multiplied by the Q factor. Q factor is determined by tank losses.
The circulating current is roughly equal to the measured circuit current draw multiplied by the Q. For example if the current draw is 5 A., and the tank Q is 50, the circulating current could be 250 amps. This is why the coil and the resonating capacitor gets so hot so quickly.
By using many smaller capacitors in parallel you distribute this current so that no one capacitor will be subject to huge currents.
3) The voltage across the capacitor is roughly 2 pi times the supply voltage. Select capacitors with a voltage rating about 10 times the supply voltage.
4) Two critical ratings of the mosfets are: 1) the drain-source breakdown voltage. Each mosfet will be subject to a voltage of roughly pi times the supply voltage. The mosfets should have a voltage rating of at least 4 times the supply voltage. 2) Drain source current rating which should be calculated from the desired wattage of your circuit. In addition, the drain-source resistance should be a low as possible in order to minimize the head dissipated by the mosfets, and also to maximize the potential power available from a given supply voltage.
Along with zener diodes to protect the gate of mosfet, it is recommended to place a small resistor (10 ohms is good) in series with the gate to damp out ringing which can subject the gates to excessive voltage. The gate of a mosfet is quite fragile, and should not be subject to greater than about 20 volts. 12 or fifteen volt zener diodes are recommended......
I hope that this helps experimenters with this useful circuit, and thanks to GreatScott for the excellent video presentation.

May I have circuit diagram?
This is a great piece of information.
Adding capacitors in parallel might help reduce heat/load on the capacitors itself. How could one reduce the heat of the coil without a fan, or pumping water through it? I have tried to mess around with the windings but is not effective in keeping the coil cool. Your help would be appreciated. Someone has suggested that a thicker copper wire should decrease the temperature of the coil.

A cool idea would be to make an induction heating probe that was driven through a flexible cable. That would be very useful for soldering plated iron standoffs onto pcbs.
I love that about every 3 weeks, there is a brand new, fresh video waiting for me to watch here!
The only hot knife video I actually enjoyed.
Red The only hot knife video you should be watching.
so i +1
Red same
I don´t understand why so many people watch these hot knife videos
Me neither
i think people find it satisfying when hot knife effortlessly cuts through stuff.
Because some of it is funny.
CZcams changed its recommended video algorithm and I would say nearly everyone has had the hot knife videos in their recommended tab leading to a huge spike in views/subscribers.
I guess, "hot' is popular key word when people searching for videos
It’s been so many years since I’ve drawn a circuit diagram. Yours are beautiful, makes me want to go back
me puke.
Thank you for giving me the explanation about the transformers with the plates.. I always thought it was due to design/build reasons.
It just blows my mind how much you know about this...
Rodrigo Pereira I think he reads of a book or his notes before telling it in his video.
Jonny D or he just studied engineering
Hoang Seidel Probably thats it but he doesnt know things to much more complicated?
More like electronics or physics than engineering alone.
Rodrigo Pereira standard knowledge for an engineer
Oh boy, now we will have more 1000 degree knife videos

Rounak Dutta it's great jk
Great editing with the hand-drawn schematics, thanks Scott!
your sense of humor is fantastic, thank you
0:24 Just btw, never cut PVC pipe with heat, as it release toxic chlorine gas. So avoid doing that
Good to know. A saw works better anyway.
GreatScott! Can I use a schottky diode instead of the UF4007?
Don't lots of things release chlorine gas? Like bleach, and, um... lots of other things?
Chlorine together with Carbon and heat, at least open flame, produces Phosgene gas, (any one who has worked CFC air con. have come across it), and that is really toxic.
Soldering also releases toxic fumes, that's why you buy a fume extractor, or solder near an open window with a fan.
I really love the addition of the handwritten calcs and diagrams!
Thanks for showing this to us Greatscott.

When removing enamel from copper wire, first burn it off using a lighter or something. It will come of really easily. On some thin wires, using sandpaper will risk breaking it.
My favorite part…”and now that we understand the basics of induction heating”. 👌

Me: dafuq?
Agreed, there's alot a baloney when it comes to Mazzilli's so called simili "ZVS" topology applied to IH drivers - which typical lemming mystifiers are now satisfied to refer to as a magical "DNA" (...) despite the simple fact that removal of a flux concentration core in Mazzilli's Flyback Transformer can't reasonably be expected to work just the same as when he got photographed besides his Tesla Coil work, in 2008 ~ 2009...
So, over a full decade has passed and yet today's fanboy tactics are being used to manipulate vulnerable people using half-lies and plain omissions. All of this just to revalorize obsolete PCBoards with ZERO protection, in an attempt to deny/ignore true technological advance in favour of getting delusional over IH Drivers supposed to cost less than a month's worth of pizza delivery i guess!
Ah, and of course you never get to be shown any realistic Gate Waveform signals, much less in relation to their resulting output, as if the Mazzilli topology never inspired serious papers in superior institutions of knowledge before, for example:

Here we must forget about frequency vs alloy optimization, never heard of semiconductor junction recovery charges, nor parasitic resonances and so on!! As if electronic design has become just another excuse to justify the one other hobby that gathers the followers around some "social" love-to-hate activity instead - totally unable to dialog via relevant arguments, not to mention i got quite successful on Reddit illustrating such mediocrity in all its virtual glory... Much like the rationale behind half of USA still standing behind Trump even today, e.g. throwing a dice would easily beat such type of "science" that they claim to "work" (until it fails, then a deafening silence covers their few voids), while in fact nothing is ever done to prevent a catastrophic forbiden condition as "Shoot-Through" in the 1st place: imagine, these days an electronic breaker is supposed to take over but only after the short-circuit has started - and we're talking about very serious current being involved nonetheless. Go figure where's the FuckCombustion NASA engineers!...

Good Day, Great Scott!, and Thank you for your video. This is very nice information indeed. If this science works for me someone will get a cookie. Happy Holidays to you and yours, and Thanks again!
"Sadly this is the type of content people enjoy". You're the best.
I agree, too many people enjoy the heated knife cutting content.
In addition to the differences in resistance and magnetic susceptibility, different material also have different specific heat values. Aluminum, for example, has a much higher specific heat than iron or copper, steel, titanium and is about 7X that of Tungsten. So, it takes more energy/heat to raise a gram of Aluminim than for many other metals.
Indeed.
And water is even higher
@@dubmob151 -- About 5 times higher than Aluminum. There's a reason it's used in radiators and heat exchangers...
Now I finally understand what my physics teacher couldn't. It's mainly the losses of magnetising wich heats up tha cookware.
Thank you :D
Wow, i like the way you explained the theory and the practical. I subscribed now. Thank you
"Sadly this is the material people like watching" I feel you bro
This is awesome, great video 👍🏻👍🏻
Thanks for sharing this knowledge
Thanks for the videos. I'm a student (Studying to be an electrician) and I reference your videos to my class mates for examples on many things.
I am working with my 7 year old son on electro magnetic experiments. He also observed the change in heat when we used a thick iron screw as a core. However, my equipment is really scrappy and I am missing a lot of what you might have at your disposal. Do you have a recommendation for equipment that you’d see as a minimum necessary to produce repeatable results?
3:55 Just the tip :P
yes 1:34
Don't you hate it when you're forced to only insert the tip
33:55
Unbelievable knowledge.
Great video! Thumbs up and subscribed!
All of these induction videos have such small coils, I would like to see one large enough and powerful enough to be used for recycling purposes such as being able to pass an aluminum can through the coil and powerful enough to melt extruded aluminum such as window frames and even able to melt brass.
Get a thicker coil with less windings
to do that you need "transistors" the size of a pack of cigarettes, something that can handle 1200 volts and 800 amps, maybe something like the MGQQ400Q1US11 by Toshiba
you make me want to spend lots of money on things i will probably use 1 time
Once you collect a few tools and supplies and start scavenging through old electronics. You put them together and blow up tons of circuits. Then you finally make something that works. You can't figure this stuff out without letting the pixies loose. You learn more from your mistakes. Go let the smoke out of something.
I did that once in Vegas ...
Always doing that XD
Great presentation
Very nice, clear, helpful video..Thanks alot hoping you will provide us with such excellent videos in future

Excellent
Simply use a cheap 40watt soldering pencil and a box cutter blade. Use the screw that holds the soldering tip, remove the tip and attach the box cutter blade through the hole in it to the outside of the heating coil, that secures the tip. So instead of a soldering tip you have a razor blade that is constantly heated by the solder pencils inductor. You don't need to keep heating it up; it stays hot. Cheap soldering pencil (40watt) stand, flux, and a small rol of 60/40 solder at Walmart = $9.99 and a pack of 10 razor cutters = $3.49. ⚡⚡ I use my variable solder station with a small coil of wire clamped in place of the tip, on my heat mat to keep my coffee hot. Great stuff in your videos. Your insights and knowledge seem to fill in the few gaps in mine. I'm a southern redneck in South Carolina US. I never throw anything away. If it will cast a shadow; it has value if you know where to use it. Imagineering. That's what you get from a BA in economics, a BS in Computer Science, a Masters in Physics; Optical/Acoustics, Quantum, and Classic Mechanics, undergrad in General Chemistry, Masters in Ancient Biblical Dialects, and finally an EMBA in Business and World Economy. And all but one degree was tuition free. But through it all I am a musician and musical instrument amplifier and high end stereo tube amp repair tech. I have a brain full of almost useless academia; but have always been a general "hands on" repair craftsman for over 45 years. Love your videos. I also write code, starting with the assembly machine code for the intel 8088 and 8086 back in the late 70's and know my way around the other 80% of the bandwidth of the Worldly really wide Webulator. White hat.
Very Good Idea
I am amazed by your knowledge and abilities. You indeed inspire me. Which software did you use for the circuit diagrams?
I think its Easy EDA. Its free on the web , and also available as computer app.
Pretty sure that's KiCAD, open source and very powerful EDA. Used extensively at CERN (among others).

1000 degree knife :)
Nice electrical engineering knowledge!!!
You made me realized that I still have a lot of things to learn
must build this for heating up knives
lol you actually drew dozens of em?😂😂
M'well a couple others did it before:
Mazzilli around 2008
Royer in 1954...
Iron (steel) 26-Fe, Cobalt 27-Co, Niken 28-Ni: They are in the Iron-magnetic group. the Foucault current (AC) will make them be hot (the ingot or bar form of those materials is easily to transfer heat)
Nice clips about...,
Induction heat is often used for harden metal that has ferro- or paramagnetic crystal, i. e. knife sheaths. Some case hardening or surface hardening.

"ROOM TEMPERATURE KNIFE VS INDUCTION COIL!"
Not everyone like those hot knife videos, i really hate those.
What i need to do to create a coil with a diameter of a mug?
is the mug made of metal? Induction heating only works on metals, not ceramic. Though I agree, I don't like the hot knife videos. They are absolutely boring.
Jonathan Kayne yes it is, i guess its aluminum, but im not sure, my plan is a coffee warmer.
You could make it just like he did but you'd have to make the coil larger than the mug so it'll fit. Plu you'd have to remember that the coil is heating the MUG which is in turn heating the liquid, so be careful and don't burn yourself.
steven kutschat
but still the same winding count?
because the diameter of the coil will be greater than the shown on video.
I don't know if I can help as far as the math goes, but I have about 3 industrial induction heaters that we use for drop forging. the coils are really large and it seems that inductance of the coil (AKA the diameter) has no effect on it. however, the coils are made of a copper tube so that water can flow through them to keep it cool. therefore, I would recommend you use a thicker gauge wire to let the resistance of the heating coil.
What an accurate and perfect handwriting! Chapeau!
Good job
Can you make a 1000 degree knife heater with this?
yes
carl elg Kedar done this check his channel
Just because something *can* be done, doesn't mean it *should* be done, leave all that "red hot knife Vs. . . . " bullshit to the kids playing scientist (and when I say kids I mean both actual kids and the "-trapped in a man's body" varieties) and away from actual scientific resource channels.
Materials cease to conduct enough current at high T°, limiting their max temperature. Although idk if 1000°c is achievable
BitsAndBites Thanks for the answer but I still would like to se great Scott answer if he will make a 1000 degree knife warmer
I was forced to just insert the tip of it....lol
Very nice video dude,
What is the maximum degree iron can reach inside the coil when enough current is delivered ?
4:35 The word is Hysteresis or magnetic resistance. When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed.
I really wish I could write like that.
I wish I had his understanding of electronics but it is not my bag.
it's like the 1000 degree knives but in a scientific way
FreeShit ikr!
FreeShit more advanced than using gas torch!
Pretty cool. I would like to build one of those as I have the required parts for it.
thank you very much
i don't really understand the circuit. so the 2 coils connected to VCC are just to "transfer" it to . constant current source? seems kinda wastefull. why not use Transistors for that?
and what are the mosfets actually doing?
i have the same doubt, few comments ago i tried to give a partial explanation by myself, but i am not still sure, anyway try to read it. Uhuh, why high voltage capacitors ? Do you know ?
"sadly people seem to like more videos of that knife thingy."
