Some updates: A few better pictures and the equivalence between an Oudin
coil and a Tesla coil.
About Oudin, I found this article:
"Sus les résonateurs et sur  l'effluve de résonance", Comptes Rendus,
pp. 1632-1634, 1898. There is a reference to the first description of
Oudin's coil, in 1892. The article can be seen at gallica.bnf.fr.
There is a comment at the end saying that the effects of long
exposure to the "effluves" of the Oudin coil are similar to the
effect of exposure to X-rays.
I had the silly idea of drawing a long arc from my coil to a metal
sphere held with two fingers. Lasted less than 1 second. Now I have
pain in all the joints of the fingers... These things are dangerous.
