Can somone tell me how to make a safe T-coil

[turborunner]

Hay, I'm not 100% shure that this post should go in this forum, sorry if not. Anyways here it is. I'm pretty new to tesla's work and am dying to build a tesla coil. I see instructions all over the net that seem to be safe, but they use transformers that put out deadly current. I don't want to replicate one turn it on and kill myself. Could somone tell me what the difference is between a deadly tesla coil and a safe to play with one is? Is there a certan dictating component(transformer, coil size, capacitor rating, etc.) that I can use as so I can rest assured the plasma arc won't fry me? Also does this change when making larger coils? Thanks!

Sure. Check out this view and I think you will see the difference.

what the difference is between a deadly tesla coil and a safe...

The answer is: the person standing infront of it.

In principle, Tesla coils are as safe or as dangerous as you want.
Depending on the ratio of the turns in the primary and secondary
coils, you will get a bigger (or smaller) voltage.

In cars, the ignition coil needs to generate 10,000volts to 20,000v
depending. Your coil could do the same or more.

This is what some Aussies, hopefully not fired up with cans of
Fosters, are up to:

It is not the coil that is dangerous; it is the person.

I thaught it was safe to be around any amount of volts as long as the current is low. But pluging somthing in thats powered by 10kv 500mA transformer sounds like it would kill you. Whats the ratio(prim coil/secondary) of a safe to touch tesla coil?

Tesla Coils are HV and there is always a danger involved.

Perhaps you should build a solid state "tesla coil".

Here's one that runs on 6-24 V and requires only one transistor. It's basically a joule thief on steroids.

Single transistor solid state Tesla Coil

Or you should perhaps buy a kit like this one.
