Electricity can be fun!


I was bored...so I built a device that can discharge 330volts at about 5-6 amperes...

video of my device

Its kind of dangerous, so I don't think I should say how to make such a device...

interesting, but kids play.

I didn't make this but check this out. It is a Jacobs ladder using a transformer from a neon light fixture. We are talking 12-15 kV here.

I have a couple ballasts like that out in my storage. One of these days I'll get around to making a ladder.

Ah, I have read about those ballasts. Wish I had one laying around!

If I can get the right transistor I might be able to put my flyback transformer to use...then I'd get 40-50 kv at 15-25 ma

I do have an old microwave transformer, I know they aren't good for ladders but I might be able to get that secondary out and rewind with large wire...might get 3 v at 70 amps and melt some things...

look around the 'net for "tesla coils". With your interests, it sounds like something you could really get in to.

Oh yeah, I always thought about making one of those. They are pretty cool.
But are somewhat time consuming to make...not to much of a problem...

For a pure resistance, watts = volts times amps.

330 volts times 5.5 amps = 1815 watts

120 volts times 15 amps = 1800 watts.

Would this invention of yours be called a "transformer"?

Actually, I feed a transformer with 1.5v, creating 330 volts at very little current, then they feed a capacitor bank.

I do have an old microwave transformer laying around...I should put that to use...

Back when Coke bottles were made of thick glass, we put one wire from one of these neons inside the bottle and the other outside. The spark would start out avoiding the glass but then it would go through the glass, all the way to the bottom of the bottle. It left a line in the glass.

Then you turn off the current and wait.

Soon there is a little noise, and the bottle falls into little pieces.

It's better than watching the grass grow. . .

sounds like an interesting science experiment.

Do they still do those in school? It seems like everything in schools is in a book or on a video screen anymmore. No hands on.

Some hands on...but mostly video or book.
