I see your tesla coil and I am impressed but i would like to see it power something like maybe something that i would plug into an out let. A coffee grinder perhaps or something that i am paying Big Energy to do for me.
That's an excellent question, and I'm still trying to figure that out myself. My understanding, from what I've read before, is that there is a transient high frequency that occurs between the 60hz oscillations from the transformer. So imagine a 60hz AC sine wave, and as it rises and falls you have high frequency that takes places between the peaks.
The acutal high frequency output is coming from the output terminal on the secondary though. The RF from the spark gap is a side effect.
@ct92404 well, it actually comes from the primary coil and capacitor creating oscillations. When this frequency gets close to the secondary's resonance, It creates the voltage rise.
It's been a while, so I don't really remember. But figure about $20 for the transformer, I think a spool of 28 gauge magnet wire for the secondary cost about $10-$15, then all the wires, screws and other hardware for the spark gap and safety gap, etc probably cost another $10 or $15. Then the wood to build the base, maybe another $10. I would say that together I probably ended up spending about $100 to build it the way I wanted. It seems simple, but everything adds up.
What is the average power consumption for a coil roughly the size of the one you have constructed? I don't want the lights dimming in my neighbor's house...I and my dad will be building one using about 70000 volts, but that is just for an extremely short period of time during peak operation. I need to know whether to buy simply a transformer and a bunch of capacitors or if I should invest in a generator.
Well, my coil uses only 120 Watts. For a comparison, your computer is using more power than that right now. If you're going to build a coil that generates 70,000 volts, that still really doesn't say how much power it's using. The amount of power a Tesla Coil uses really depends on the voltage and current of the transformer. Mine uses a transformer that supplies 6kv at 20ma. So, 6,000 volts X 20ma = 120 Watts.

does the spark gap run at the same frequency as the primary / secondary resonance?

I love the evil sound the spark gap makes. Cool Tesla.

wow amazing
heya can you make a video of the tesla coil effect on a CD?
I read and saw some pics on the internet that says it produces a great scene. : )

try to put a ball on the top instead of a plate :D but still real good vids man.

DONT TASE ME BRO! but seriously i would be afraid to even turn that thing on, let alone get close enough to film it, its scary looking :D

lol...well even I still jump a little when I first turn it on, and I built the thing!

is there a way to make the spark gap quite
highvoltagemouse 3 years ago
quiet...no, not really, unless you have it in some kind of enclosure. But then you'll have a big problem with heat.

couldnt you use a light burnt out light?

Hi Chris...Great job!! Do you know how much it cost you to build the tesla coil from ground up? Thanks!

Thanks Chris!! Wish you the best for the gaseous power transmission you are working on and all of your other efforts

I meant Watts. Sorry for the confusion. Dad said that we need a generator definitely. Thanks for the great video!
