Mini tesla coil? Answered

Is it possible to make a small tesla coil with a toilet paper roll for the secondary coil?


I suppose it is but I wouldn't recommend a toilet paper roll it's simply not a good material for it just get a small piece of PVC or even a glass jar could be used anything other than a toilet paper roll also non conductible or flammable.

when you say a glass jar, do you mean a jam jar, or just a little tiny jar?

That depends on what size you want your coil they are both usable I think Nikola Tesla built his first coil around a glass jar.
