    In this video I am going to show you how to make a powerful induction heater at home.
    This bladeless fan is powered by a 12v adapter and is is very useful for those having kid around them.
    This is a powerful induction heater that can handle surges of upto 300 watts that is a lot of power to heat up any metal to red hot. This induction heater is completely homemade.
    This is made possible by using a printed circuit boards that I have ordered from JLCPCB.
    They are offering very low prices and high quality PCBs so visit their website and get an instant quote.
    For more information and details such as dimensions part lists schematic and gerber file please visit my Instructables blog.
    Moreover I am also giving away the remaining PCBs to five lucky winners. So subscribe,share and like this video and drop a comment below about what you want to see as our next DIY project.

    Regards.

    @DIY King
    which components do I need to order so the heater can "survive longer" and not bur so quickly?
    (more reliable)
    which parts need to be "oversized" or from a Japanese/US/Korean supplier?

    thanks

    That was a great video. You should be proud of your production. I've used these quick turn around PCBs before, but they were for much more complicated boards and took quite a while to design and verify. But I was really impressed with your attitude for use with these simple boards. As for constructive comments, you do need to improve your soldering skills. And to really use 130A you would need to "seriously" beef up all connectors, wires and PCB traces to deliver that sort of current to the coil. I suspect you are only using a fraction of the full capability of that power supply.

    Whelp! I had no idea I could order custom PCBs with quick turnaround for such an affordable price. I purchased a Cricut vinyl cutter to make masks, but this seems like a better option for some more tedious builds.

    PARTS LIST BELOW COMMENTS:

    COMMENTS:
    Circuit diagram , plz, or you are just a shill for this jlcpcb place. How many amps is the PSU supposed to be? What exactly does adding a 10 ohm 2w resistor do to your 15v input voltage? Does it affect the amps? I checked out the linked Instructable, while IT has an INCOMPLETE parts list it is still lacking a circuit diagram.
    Awesome clickbait shillstub, though, dude. Lookit you, aren't YOU so smrt!! /sarcasm

    PARTS LIST:
    NB that I am occasionally using the keystrokes "uf" to designate micro-Henrys in this list BUT ALSO there is a PART with that prefix.(UF4007) DO NOT USE IF4007 diodes or your entire project WILL go up in sparks and smoke. Ye Have been Warned.

    2* 10k resistors
    2* 2200 ohm resistors
    2* UF4007 diodes (UF (Ultra Fast) NOT IF (Is Fast) OR YOUR HEATER WILL GO SPARKLY-BOOM)
    2* 1N821 ZENER diodes
    2* IRF540N MOSFETs
    2* capacitors/banks ~400VAC non-polar 0.33uf capacitors. (Volts seems to be more important than Micro-Henrys (uf) here, ideally you want 800VAC of caps but ya can play around a bit with the numbers.)
    2* 30mm toroidial (circular not tube shaped) ferrite cores OR 2* 100uf inducers
    Semi-optional part: f NO CLUE WTF a "100uf inducer is you WILL need enough 1.2mm solid copper wire to do 30 wraps around EACH ferrite core
    12v PC fan(NOT a cpu blower)
    2* heatsinks (aluminum or copper) that fit your MOSFETs
    1* small tube of thermal paste for an excellent thermal bond between the MOSFETs and their respective heatsinks (this step is entirely missing from the vid and Instructable but all ya gotta do is smear a thin layer of paste on the surface of the mosfet(s) that touches the heatsink directly before screwing them to such)
    1m (100cm) * 5mm diam. copper pipe
    10cm* 2.5cm dowel (any material that you can wrap a coil of the 5mm copper pipe around, I suggest wood but whateva ya use is fine)
    12v power supply with sufficient amps (I'd guess 20+, but this info is sadly lacking so idk this for sure. TOO MANY amps is better than not enough)

    VERY USEFUL but NOT needed tools/extras:
    Multimeter
    impedence meter
    volt tester
    ohms tester
    solder iron
    solder

      JP jay - Yes, the technique could be better.
      Never try to melt the solder with the iron. That will lead to what is known as a “cold joint”.
      Heat the joint with the iron and use the solder to determine when there is enough heat. As you heat the joint, keep touching And removing the solder from the components being joined. When it is hot enough, the solder will melt quickly and be drawn into the gaps to create a good bond. At that point, remove the iron so as not to overheat the joint and burn off the flux.

    resistors DO NOT drop the voltage. They drop the current!!!!

    • Joseph Helmstetter Jr
      Joseph Helmstetter Jr 4 months ago

      Jake Joris We measure the voltage dropped across the resistor. The amount of current that flows through a resistor is a result of the voltage dropped by the resistor divided by the resistance. You can change the amount of current through the same resistor by varying the input voltage. If you increase the voltage the current through the resistor will also increase.

    'Up your game' by passing coolant through the copper tube,... it will not affect the field-induced eddy currents in the metal to be heated. Your tubing could then handle (along with the caps and the MOSFETs) far more current.

    Great video. I will try this soon. Just one question: I probably won´t be able to get the same values for the capacitors and inductance (the one you got from computer scrap). That would affect the frequency and this way the induction level. Is there any risk?

    DYI King: Thank you, I've limited knowledge of electronics so this info was great worth. Thank you once again. You did not say if you insert sand into the copper tube after it's bent or was that a nutty question lol? also can this setup melt metal? If not could you show me how to build one that can. I've seen one done on another channel but it was not as classy and professional as yours. Peace:-}_~
