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.
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.
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.
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: docplayer.net/26964431-High-voltage-resonant-self-tracking-current-fed-converter-a-thesis-presented-to-the-faculty-of-california-polytechnic-state-university.html High voltage resonant self-tracking current-fed converter (2010-Mar) p52/152 - Mazzilli Converter Topology 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!... Please revisit in 5 or 10 or 15 years, if possible.
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
Thanks! A couple years ago when I was 10 I saw this video and went to the local electronics shop and built the exact thing just from looking at the way you did half the parts where from scrap items and ended up using it till I moved house
RUclips 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.
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.

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.
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.
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.
I usually avoid videos like this , but I figure this can't be one where things are heated, and just a lot if playing around, like the videos where they build fly backs, and make arcs the whole video, but this is much better, great video Mr Scott!!!
The best demonstration of the phenomenon that exists on youtube. You showed the results with different materials in a very simple but useful way.The little knife is just the appetizer. Congratulations.
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.
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.
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
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?
I don't understand any of this but watching the heat move up that screw as it tempered(?) looked beautiful. That's a thousand times more interesting than hot knife videos.
@@Egzoset I don't know what you mean. I don't receive any compensation or benefit from this thing. I have no connection whatsoever to it. I was just giving this RUclipsr a well deserved complement, that's all.
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.

can you pls make switching mode inverter 12v to 220v in one of your next videos pls !!! I made same induction heater last month but now I understand how it works thx !!!
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.

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.
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)
Using the Texas Instruments TPA3255 chip one can safely theorize nearly 5 KW could fit some 6 x 6 x 1.2 ~ 1.5 cm PCBoard, double-side...

was about to make a 1000° knife joke, you was faster...
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.
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)
"sadly people seem to like more videos of that knife thingy."
nikoli gogle lol, I love that part...
What is that knife thingy again?
Exacto knife
Suggestion: DIY Class D amplification video
Using the Texas Instruments TPA3255 chip one can safely theorize nearly 5 KW could fit some 6 x 6 x 1.2 ~ 1.5 cm PCBoard, double-side...
For example:

But of course there's more to it.
Yeah only insert the tip😂
nice sir .. stay creative
I really wish I could write like that.
I wish I had his understanding of electronics but it is not my bag.
You got yourself a better food heater than a microwave. Lets all make popcorn with it and watch Scott.
P.S: I’m sure that there are nor micro waves destroying your food properties now.
4:55 According to the simple schematic-----------say what?
I didn't understand one thing you said. You are a very bright individual
Who else coming after watching Electroboom's recent video 👍
Me!
I was about to comment the same thing lol
Your hand written schematics are beautiful and I’m jealous haha.
It always sounds weird when you say "i-ran", it's pronounced "i-on" :D
Or i-urn
It's personal preference ("eye-run" or "eye-uhrn")
what are you austrialian? It’s pronounced literally as such “i -ron”
I yearn for iron
great job. you do some of the most and best explanations on youtube please never stop
"I can start cutting through things with a hot x-acto knife because sadly this is the type of content way too many people enjoy watching." Hahaha, that was funny. For real though. People watch some stupid shit and that kills brain cells instead of actually teaching something.
Nice project
Don't give MrGear any new ideas
Almost at 1 million scott :D. Your channel is absolutely fantastic
