Selfrunning cold electricity circuit from Dr.Stiffler

[DrStiffler]

@Mark
Thanks again. My observations were only with the signal generator attached. If the scope is connected the OP seems quite strong. The Blue LED turns on quite nicely then.


@DrStiffler,
I have a batch of the 680uH cores and as they are the critical part of this investigation I wanted to clear up a few points.

1- The number turns you specified at 9 turns but I count 11 in the picture.
2- You did say that the sense of the L3 should be the same as the L2 core. Please can you verify that. Either my L2 cores are wound the wrong way by the manufacturer or the  image may be mirrored somehow.
3- You use a symbol for the L2-L3 combination which indicates 3 different windings. L2, as arrives from the supplier only has one winding. Am I missing something?

The coil issue is covered earlier in the thread and on my web site, but the primary needs to be wound in the sane direction as the secondary.

The diagram although looking like two coils on the secondary is meant only to show that the secondary has more turns than the primary.

To find out if you did wrap one wrong, look t my site, I have a whole section on how this was found and solved.

Stefan,
Thank you for the report. So in your experiment you did not need the core after all. Are you talking TPU now?!

Is your scopes power input ground floating or connected to the eartth of the mains?

AM

Yes, my crappy scope is grounded unfortunately.
I have to glue some tape onto the ground wire, so it is isolated.
I will do this today and will see, if it makes a difference.

I want to take this opportunity to voice my highest respect for Dr. Stiffler AND 'the whole team' that has gathered in the operating theater.

I watched your video, harti, and noticed that you use very long cores together with a relatively short coil. You insert the core so that it protrudes very far beyond the left side of the coil and stands out only very short beyond the other side of the coil.
Maybe it would make a difference if you positioned the coil symmetrically in the center of the core.
Note that Dr. Stiffler's 'magic coil' is also wound symmetrically over the middle of the core.

Thanks again to everybody.

Yes,I tried it already and only at the end of the core I get better brightness than in the center..
Do you think it would be good to break thecore apart and make it shorter ?
Maybe it depends on the length of the core also ?

Maybe some kind of standing wave inside the core ?
This would give a whole new perspective to it all and
the input frequency alsomust be choosen to have a standing
wave inside the core ?

Dear Ben,
well with my selfbuilt oscillator the tuning is not easy.
I have to get the trim-capacitors to turn right and the frequency
can also still shift a bit.

I have 2 trim capacitors in parallel,
this one, 3 to 40 pF :


and
this one, 6 to 80 pF:


In the loop back of the inverter I have a 100 Ohm resistor.

Then I tried to replace the 100 Ohm resistor with a 100 Ohm pot and
75 Ohm resistor in series, everytime I touched the pot it
changed the frequency dramatically, so I am better with the fixed
100 Ohm resistor and the trim caps.

Maybe I should buy better equipment to get myself a better
function generator.
I will see, what I can find on Ebay Germany.
Or maybe I will hack my old function generator to queeze a few more Mhz out
of it... I will see..

Dr. Stiffler has just updated his website with
a higher power incand. bulb output experiment.

Have a look at his new scopeshots.

Reminds me a lot at the scopeshots that Roberto und Otto
got  in their TPU research...
