Hello everyone,
A little bit back (been waiting for the new rules since then) I built a plasma speaker (with a lot of help from the people over at all about circuits) and did a science fair project on it, in which I varied the ultrasonic base frequency and measured the maximum distance at which it would arc, I wanted to do further testing involving the duty cycle and create a carpet plot but ran out if time.
Heres a youtube video of it in operation

(subscribers would be nice, just sayin)
It wouldn't let me attach the word doc and excel doc, so I went ahead and attached the project writeup, the three blank pages being where the excel data goes.
Thoughts?
