Since there is talk about the perfect Tesla raffle, and since the first thing that still come to mind when I hear the name Tesla is "Tesla Coil", this seemed like a good time to start a discussion about the perfect Tesla Coil.


http://www.instructables.com/id/How-To- ... Coil-SGTC/

Essentially, a Tesla Coil is a type of alternating current transformer that operates almost like any other (transformers are found in many electrical and electronic devices and are used to step up or step down the voltage of an alternating current signal). However, it relies on the principle of electrical resonance in order to massively increase the voltage of the alternating current signal.

In other words, "resonance" is the key to building the perfect Tesla coil.

A project more to my taste and what I currently have the what for on a shelf is a Jacob's Ladder:

I don't have a FRANCFORMER. What I have is an American made standard neon transformer, the FRANCFORMER looks like it is a French made standard neon transformer. That or it is used to light oil burners, probably that. Geometry of the case and hookups is about he only difference.

One needs a lamp cord and plug to power the transformer. The transformer. Two 16 inch lengths of bare number 10 copper wire. Pliers are nice to help bend the wire. The American neon transformer has big knurled Bakelite thumb screw connectors so no tools are needed to attach the ladder or the cord to the transformer.

And what is most nice about this project is it will be producing the mad scientist effect upon the neighborhood within an hour of beginning work upon it. It's not just the light show, it's the sound, and it's hair raising too, if one gets at all close to it.

I last had it set up about ten years ago. I first had it set up when I was 18. It might just need to be unbent and dusted off again. :)

Full disclosure, I hate the sound of theremins.
