Hello to everyone,
this week end i did the first start to the tesla coil i built.
Of course it doen't work...
too bad.
But, what the problem was? i suppose a wrong tuning.
At the beginning there were no sparks at all, then i put the terminal of
the sparking gap closest each other, and it starts sparking...but still not
lighting bolts from the top. then i put a copper wire on the side of the
toroids, and some little sparks come out, almost 3'' long. I was only able
to turn on a neon tube at the distance of a couple of meters.
very poor.
i know, that a coil so big should generate 75cm sparks ... what is wrong?
help me please.
bye bye
