Wow finally. If someone can replicate the effects, it's him

It looks like he has. I am anxiously awaiting v2.

Hi Guys,

I have all the stuff to replicate this JLN's experiment (http://jnaudin.free.fr/wfc/)
the Stainless Steel tubes, the bifilar coil, the 4093.
I just lack of this BUK416-100 N-MOS Power transistor.

(http://freenrg.info/Pic/BUK_416-100.jpg) 

BUK 416-100 
Vds : 100 V.
Id = 150 A maxi.
Ptot : 410 W.
Rds : 0,009 ohm.
Dim : 38 x 25 x 12 mm.

59.90 Euros..... :-\

I'm far from an electronics specialist.
I'm just wondering... According to the circuit:
Do you really need such an expensive 'beast' (150 amps max) ???
Is the diode part of the the transistor? If not it is not specified.  :-\

Search the datasheet.
Found one:
http://www.datasheetarchive.com/pdf/902013.pdf

As you can see, the diode is part of the fet.

The 30V powersupply (VDC-1A) can only deliver 1A, so I'm sure a cheaper fet can be used. Still looking

Have you noticed this:
Below the measured specs of the new _insulated_ WFC v1.1.

He insulated the inner electrode, to prefent currentflow.

@Alan,

Thanks a lot for the datasheet!
I did not succeed finding it. :P

What would you advice for the HVDIODE?
A diode from a Microwave Oven, or some 1N5408 in series?

I think a microwave oven diode works well, but I'd say, try em both :)

The secondary will be 550 volts, also the HV diode is necessary for the high back emf kick (But I am not sure about that, anyone?)
Also watch this, I'm sure it will help you: http://www.youtube.com/watch?v=YSmxliLwhT8

Transistors are cheap , although this1 is hight power  ... and it is very important that it will is low resistance1 (drain to source), also it may be fast recovery transistor ...and so on. This 1 got 4 connectors also it may be with 2 gates ....
I do not find smart to use so expensive transistor there is just no need for it ...

And about amperage ... U may need 410 w transistor after all coz alternator in car is generating up to 1 KW ... Any way hes using this1 as switch so i do not really know ... There may be no need for 410 W ...

@Alan, Jokker

Thanks for your "feedbacks".

Yes, 550 volts for the secondary. 220/12*30 =/= 550 Volts (without any "back emf kick").

I guess I will use:
one IRF540;
a second 4093 for the 2 square wave generators;
a 12 volts DC supply for the 4093s.

According to the circuit, the DC supply for the 4093 should be 5 Volts????.
http://jnaudin.free.fr/wfc/VIC10diag.gif

I am very doubtful about some JLN's specifications.

For example, if you try to reproduce the very simple JLN's "negistor"
experiment, with a mere 12 volts bat, you will almost certainly fail! :(
see : http://jlnlabs.online.fr/cnr/images/negoscdg.gif
From (http://jlnlabs.online.fr/cnr/negosc.htm).

Why? Because the DC supply should be fine tuned and this is not specified.
Depending on the cap. and the coil it could be 8.6-8.8 volts or 10.1-10.5 volts
(for ex.)
I managed to get better results with different values.
This is off topic , but if you are interested in, some picture are on:

My suggestion is to use just hight power switching transistor. By the way u may want transistor what is meant to work progressively.
I just did exams at school and got pretty good results so i pretty much know the thing  ;D.... U should use stabilization transistor (impulse voltage regulator). Because ...
It is hight power it should be fast recovery and it should be perfect for pulsing circuit ...
Any way 100 KHz is not too hight frequency but u need to make sure that u got switching transistor. Area transistor should work better coz it got hight input resistance so u will not heat driving - oscillation (pulsing) part. Mosfet transistor maybe ....


by the way why u try to use induction element oscillator. 555 times should work like charm. They are very accurate and u can change frequency very easily and i guess it is part what u should work on.

http://jnaudin.free.fr/wfc/VIC10diag.gif

Yeah, because the output of these nand chips is 0 or 5 volt. A 7905 would work

The youtube video works again.

555's are also very easy, just google "555 tutorial" :)

And about circuit ...
U cant be so smart to build it up in you head by calculating things what are incalculable.  Use circuit simulation programs like multisim (labsoft national insruments) theres build in 555 timer tool also.

This is going to be it. JLN will have specs and they will work and be public info!!!!! I am psyched.....
