    Does the output voltage for this kind of step up module change in proportion to the input voltage?

    yOU ARE bLASPHEMING JULIAN, MY 4 YEAR OLD HAVE BEEN WATCHING YOUR VIDS SINCE HE WAS 3 AND WE ALLOWED IT CAUSE YOU NEVER USED FOWL LANGUAGE AND HES LEARNED ALOT FROM YOUR VIDS, PLEASE STOP DOING WHAT EVERYONE IS DOING.

    That 400KV stepper-upper would be right at home in any Mad Scientist's Lab.

    😂😂😂😂😂😂😂😂😂😂😂 You made my day with this HV inverter……Love your videos ❤️

    Julian what a big fuss about the 400kv (40kv?) Arc generator! Yer big girl's blouse!! 🤣

    Seriously, 'nanny' probably won't let us play with these.

    If you put the spark gap too wide they burn out inside quickly

    You should install that inverter into your doorbell to keep the religious solicitors at bay.

    the salt water fuel cell is just a diy battery

    For exposed outdoor boxes / connectors, a spray can of "spar varnish" polyurethane is your friend! A very_light_coat will keep your screws and other metal from rusting quite as fast. The reason I emphasize the very light coat is that a heavier coat has a high chance of trapping moisture – making the problem ten times worse instead of helping at all.

    LOL this isnot more than 30KV

    I put 18V into one of those HV generators. It was scary.

    😂

    With all those sparks will it weld battery clips – Marigolds ready

    Several strategically placed = great burglar/intruder deterrent! (͡ ͡° ͜ つ ͡͡°) Arf! Arf! "Break into my home would you? How do ya like half a million volts up yer jacksie pal?

  15. Avataaar/Circle Created with python_avatars Mark Hodgson says:

    The insulation would break down at that supoused voltage

  16. Avataaar/Circle Created with python_avatars Zosangliana Hg says:

    You are so scare wow i hold with my hand and shock vv danger i falldown 😐

  17. Avataaar/Circle Created with python_avatars Grant Aitken says:
