    You sir, are a master educator. I've worked in both K-12 and adult education/training for computer technicians. Your explanations,pacing, and use of visuals are awesome.
  • Great video but there's one very important thing missing at the beginning of the video. The capacitor from the microwave holds a massive amount of voltage and sometimes the resistor that is responsible for bleeding out the capacitor fails, creating a deadly trap for whoever touches it. ALWAYS SAFELY DISCHARGE ANY CAPACITORS YOU ARE WORKING WITH AND MAKE SURE THAT YOU ARE COMFORTABLE WORKING WITH HIGH VOLTAGE BEFORE YOU ATTEMPT TO BUILD THIS POWER SUPPLY. Every year people die because they put they hand where they are not supposed to.

    Hands down, one of the best damn explanations of the electronic parts of a microwave and their function i have seen
  • I will add AWESOME since it was not used yet. I spent a career in electronics and related tasks, but I have never seen a finer video. Even for myself it presents great explanations and illustrations for a good basic ohms law review. I look forward to the rest of your presentations. I agree with the other constructive comments especially those related to safety. I might add a caution to remove all jewelry when working with these voltages. Safety here can not be over stated. Thank you
  • Everyone seems to be impressed by the depth of the video… I was flabbergasted when he used the stick to point components. I wish everyone did that!!!
  • @TestEric
    My mind is blown, I have watched 10's of videos on microwaves, MOTs, and magnetron's, and this is the best and most comprehensive, you deserve more subscribers, and I'm sure you'll have them if your other content is as great as this.

    This is exactly the Microwave Transformer video that I have been looking for. Clear explanation of the process and most importantly clear explanation of how these transformers behave.
  • @JoeOlneyGym
    This feels like a proof of one of those crazy questions from a physics textbook. Thank you for a imaginative learning experience.
  • Great video. I like the narration and the high detail. Also for explaining not just how to make the supply but where each component came from and what it's original purpose was.
  • @nadahere
    Thank you for this magnificently produced presentation. I never leave comments but this one deserved it.
  • I am totally in awe with the cadence and speed of your lecture. Most of the electrical stuff is beyond me but I am now studying how you speak in the video. I hope to emulate you (in a different subject). Thank you.
  • @pauldorman
    Superb! YouTube needs more content creators like yourself! Interesting, practical, and educational. Just wonderful, thank you.
  • @Spiritman597
    Kudos my friend, that is probably the best explanation of a proper calculation test of any power supply I've ever seen and heard. I can't wait to see some of your other videos and I will be building one of these power supplies with of course a active cooling fan. Thanks again
  • I really enjoy your way of presenting all the components. I wish more people would be as educational as yourself. thank you and kudos for a great learning experience 👏
  • @7sArts
    Very much appreciate the detailed explanation and accompanying illustrations. This will help since my Tesla inspired “coil for electromagnets” to convert concentrated solar power driving a Tesla turbine. Thanks for the help and tips for not getting pulverized.
  • @Evanturar
    So much here to appreciate. A very well organized sequence with supporting calculations, consistent tempo and a great lecture voice. Just outstanding. In this design, I can’t help wonder about output lead insulation proximity to the enclosure face holes, and potential for plasma arcing through the chassis. I see great care with the panel face wing nut lugs, but the two cables seem very close. I’d love to understand how he arrived at the cable insulation.

    Brilliant. I happened to have all the components around to follow along and build. I did have some beefy resistors and a 40k probe, so I was able to test my own numbers. 6,303Vdc with no load. I learnt so much from this. Thank you.
  • Great video. I've used the same full wave doubler you use. Works well with zvs drivers powering AC flybacks too. You can double and even triple the voltage of your ferrite core transformers.
