Hi.

I'm watching your progress with great interest.
Sadly I won't be able to make any experiments for about a month because I have bought an old apartment and I will be working on renovating it so I can start living there as soon as possible. But after that I will be able to work on experiments on daily basics. 

Bye,
Frenky

Hi Frenky

good luck in renovation   

I made the same 3 years ago and it took me most of my 200 % energy.

But than what a pleasure to live in your BABY.

we live only 0ne time  so it has to be good

Yeah it will be great when it will be done. I already know which USB scope, function generator and LRC meter I'll buy for my "home lab".   
But that will be probably in somewhere in the year 2013 because I will be so broke after renovation.

Hi Laurent,

....
So this afternoon i wounded a Tesla coil. It is not flat but as i understood from the Tesla patent it does not need to be  flat. He draws it flat for better comprehension for the patent. Is it correct? 

Well, I think it is flat, there are more people taking it flat than not...   Nevertheless, the flat coil that has only a thickness or actually a length of just the wire diameter, has interesting flux fields, see here http://www.youtube.com/watch?v=O12UVMFGe2U   If you consider a thicker coil wrt the flat one, the higher the thickness i.e. the length of such air cored coils the more distance the flux has to go in air which is the worst flux conductor. In case of a flat coil there is no any lenght in air in that sense, just the copper wire diameter.
This guy also tested several such flat coils for finding their resonance frequency, see here his Part1: http://www.youtube.com/watch?v=YuevO1IhElg

Have you a proposition for a capacitor value to test with those values ? and is it possible to get resonnance or what would be the cset up to get it? 

Your 900 RPM gives 15Hz, then the needed capacitor for resonance is about 402068uF, (almost half a Farad) 0.4F.  A supercap is not the best here, not only because it is polaryzed but it has only 2.5V or 5V voltage rating, way too low value.  Maybe connecting several 5V rated such caps in series, like 5 pieces of 2.2F/5V types, to see what happens at near the resonance to the pulses. Maybe the 25V (5*5V) voltage rating is still low at resonance I do not know.

Sorry that you seem left alone in hand on tests, I can be of mainly theoritical help for you or maybe recall my own tests from the past if appropiate, because circumstances changed at my workplace.

Laurent, see what member BEP says on flat coil:
http://www.overunity.com/index.php?topic=6640.msg158978#msg158978

"The real beauty of this type of coil is it tells Lenz to blow. The induced field is perpendicular to the approaching field instead of opposing.
Bang one of these with a sharp spike and there is a 'clapping' in the center like no other. It is like stomping on a ripe banana. Everything squirts out the axis."
