This 24kj capacitor discharge bank is configured for 4500v @ 2400uf and can be charged up using microwave oven transformers. When triggered, it can release all of this stored energy in under a millisecond through a triggered spark gap. Check out the video to understand the magnitude of this thing but please, don’t try this at home.

    The maniacal laughter makes me question of this person is really sane enough to be handling such a deadly device. D:

    Did anyone notice that secondary spark? What’s up with that?

    That doll was amazing. Listen to them giggling like … well, like any man would, really. Kudos.

    or EMT.

    or coroner.

    Having done this on a larger scale in a University Physics lab, I am very surprised it would take a milisecond to discharge this. My guess would have been in the fraction of a microsecond range. Maybe if they have a resistive load in one of the leads, it will slow the discharge rate.

    last laugh coming soon…

    Love the complete and total lack of safety equipment. That bucket seems to protect (quite poorly) everything but what is right in front of the opening -the guys that built it. This type of behavior is extremely poor. Guys, get a clue, learn to conduct your business safely. If it walks like a jackass and quacks like a jackass….

    Jackasses don’t quack.

    Quack.
