Help with very small coil, 40g AWG

Postby ZAGAbuilder » Wed Feb 26, 2014 12:50 pm

I suppose you could say I am at expert level in reading and a noob in building having built only one successful coil.

I have a question and was wondering if this community could help.
Please examine the following:

Driver-
I am using a simple driver circuit kit, a 500k Pot, a rectifier diode and an NPN transistor

Coil 1- works!
L2 = 1200 turns 32g AWG, 10" tall
L1 = 15 turns 18g AWG (pancake)
Simple chrome ball torrid
= Will light a CFL to 50% on 9v
output increase is 9v => 144v

Coil 2- Fails Sad
L2 = 1500 turns 40g AWG, 5" tall
L1 = 10 turns 30g AWG (pancake)
= will not even light a small LED
output seems to decrease 9v => 0.544v

I used the same driver on each. The only thing I can think of is that the 40g wire has too much resistance, or, there is some basic concept with scaling tesla coils that I do not understand. Any advice you can give me would be much appreciated.


In my process of research I cam across this page:
http://onetesla.com/resonator
using the search term "Tesla Secondary 40awg" which leads me to believe that someone here may have an answer.


Thank you for your consideration in this matter.


PS the 40AWG is near perfect, if I test it for continuity is it indeed solid, I can put in 9v at the bottom and get 9 out the top. It took several tries but I got that badbuy wound real nice...

I'm pushing 500W through a 38.5AWG coil right now, so it is definitely not the secondary's fault - check your phasing, maybe?

Can you elaborate on phasing please?
thank you.
