Extra cool! Too bad i sold that mini coil to that colllege student for her
project or else i would attempt to outdo. Oh well, time to let someone
else take over ;) I had to push the variac to 140V to get i think 14.5"
from my mini coil. I think the fact that i had the target be a large
metallic sphere helped the spark lenght. It always made the best sparks to
large targets ;) Looks like youve figured that out as well!
