So now that I have some NST's, I am looking to the next projects...

Eventually, I want to design a TC, but for now I want to experiment with simpler projects...I have plans to make a 6' tall Jacob's ladder, and I am going to research Kirlian photography, but what would you recommend for some other fun things to do with an NST? Trying to keep it somewhat simple and smaller for now...not looking to use multiple NST's or anything like that...looking for interesting and different, not necessarily bigger.

Also looking for ways to make nice coronas and multiple arcs...thoughts, suggestions?

Jacob's Ladder is the simplest and one of the more visually spectacular. Very simple with an NST as well.

Go into the section entitled "PROJECTS" and hunt for your components or concepts via 'searches' such as "Jacob's Ladder" or NST and see what other people have done from the simple ones to the most complex. Then decide what you have parts and experience for....

Decided to take a note from Grenadier and make a Jacob's Ladder with one of my big NST's...I now have a nearly 4' tall ladder with a 4" spread at the top...and the arcs jump right off the top!

Now I just have to figure out a way to secure the top section so it wont start bouncing in and out...it eventually settles into a rhythm that keeps it 'clapping'...

And sometimes the simplest things are the best (and overlooked)...great suggestion about searching the projects section!

My wife says..."shouldn't you test that thing outside?"

Looks good. Notice how the wires start moving. That's because there's 450W flowing through them, and they become magnets and attract each other. The same thing happens with aluminum wires, but not as much.

Also, tell you're wife it isn't more of a fire hazard than a candle. Unless you used magnesium wires...

Your best bet to keep them from swinging is a teflon or paraffin separator at the top. Wood is far too conductive. You could also use copper tubing, it doesn't swing anywhere near as much.

Also, // NST's mean longer arcs and thus bigger ladders.

Did I mention i have a Master's in Redneck Engineering?

Yes, that is a shaft from an ink pen...I figured it was about the right length, and non-conductive (and there's very little heat that hits the top, it goes by so quick). Plus, the wires fit nicely into the holes...

Do the arms of the Jacob's ladder attract or push away from each other ? It's hard to tell from the video.
