    That kid is going to go places.
    Incredible work for someone his age!

    In the 80's I made PCBs by painting traces with enamel paint ( Ithe paint I used for scale model motorbikes) And then toss it in the brown ferro-something stuff. Most thing I builded did not work. I now know why. The schematics used some transistor that was as usual not for sale in the local shop. After waiting an hour until it was your turn, the salesman (an ewlectronics god in my kid-eyes) then took some book, mumbled a lot of voodoo things about beta and Vbe and after that he went to the back of the shop, after 10 minutes he then re-appeared holding a transistor. But he never told me transistors do not all have the same pin layout……..

    Really, selling a reference capacitor box and then use on of the most crappy LCR meters to calibrate ? I think I could do much better then that

    Thirteen? This young man is going places, his parents must be bursting with pride!

    Your videos are always the best do receive a notification each time you post a new video.. We'll have regrets for things we did not participate in..Investment should always be on any creative man's heart for success in life.

    The high voltage transformer, perhaps it had a broken rubber seal and water leaked in?

  6. Avataaar/Circle Created with python_avatars saimon174666 says:

    I don't like collabs, but this was cool.

  7. Avataaar/Circle Created with python_avatars David Au says:

    What an delightful, awesome young man Josh is. The 'scope couldn't have gone to a better person. Good luck into your future Josh!

  8. Avataaar/Circle Created with python_avatars Sergey Ivanov says:

    Oh thanks Good it went smoothly. I was afraid that Dave will accidentally swear in front of the kid.
    And my warm respect to Josh!

  9. Avataaar/Circle Created with python_avatars Mike Hennessy says:

    Good on ya Dave. Josh is an impressive young bloke. I imagine he'll go on to great things.

  10. Avataaar/Circle Created with python_avatars Raoul Duke says:

    Good job Josh you you have a bright future in electrical engineering ahead of you

  11. Avataaar/Circle Created with python_avatars Andrew Ballard says:

    awesome! fantastic winner!

  12. Avataaar/Circle Created with python_avatars Jacek Pawłowski says:

    Hey Dave, I would suggest to perform open and short calibration of the LCR meter with cables attached before measurements. Your values were higher probably because of parallel resistance introduced by the cables.

    Maybe get your son to build the packet radio interface and others kits, Its never too early to get them into ham radio.
    Yes packet radio is still very popular.
    NOAA still have some satellites transmitting weather images from space that can be received and displayed quite easily and weather fax is still transmitted over HF. 73.

  14. Avataaar/Circle Created with python_avatars Ben Childs says:

    It's very nice to see such a young enthusiast designing products to work with the Framework laptops.

  15. Avataaar/Circle Created with python_avatars Kev711 2001 says:

    More interesting thing about the calc is the way those old 3 color lcd displays work

  16. Avataaar/Circle Created with python_avatars Retinatronics says:

    Congrats Josh!

  17. Avataaar/Circle Created with python_avatars Re Eb says:

    young dude is kicking it! keep it up genius lad!

  18. Avataaar/Circle Created with python_avatars Henrique Ortiz Mendes says:

    Brilliant! You got me. How Sagan grew so fast?

  19. Avataaar/Circle Created with python_avatars says:

    The PSU at the start is for running an electrostatic ionizing system surprising how many different fields use these devices too.. I know of one in a lab where its used to stop electrostatic causing small amounts of various chemical powders to fly off and stick to everything when weighing very precise amounts etc etc. I beleive they are used in places with textiles / paper and foil too for very much the same thing.

    Glad to see a young bloke doing what he loves you will go far my friend.
