Jadaro,
Did you ever get 20 or 30 rectified volts from the secondary on your helmholz coils?

jeanna

You keep saying secondary - there is no secondary if it's pickup coils you're talking about - in this setup, and there's no pickup coil yet per se.

Did you ever get 20 or 30 rectified volts from ... your helmholz coils?

Absolutely! ...and here's another picture or two; I'm getting 120 volts in the first one (repost) where I'm getting 80 volts in the second one.  The second image - I have the inductors setup so that current flowing through them is such that the top of one is north and the top of the other is south, if I touch the two together while the circuit is running, the neon flashes faster or glows - and the coils stick together through magnetic attraction.

You'll have to forgive me, I couldn't capture the image while the neon was in flash, , but the second one does indeed work.

@jadaro

On my toroid i light a neon like yours but i can light 16 of those on the mk8 , from 6 mili.
I am not using scalar you can use them but its not the idea.
And none of my toroid need a cap to work?

@nop

Thank for almost saying i am right , lol.

Edit there are other things beside permeability , like flux density.

Since all toroid are different its hard to understand what is going on , if every time you make a toroid its a new type ,
use one and learn.

In the end if you still don't get it , you may not be meant to, sorry but true .

@all, jeanna

Here's two videos of the device in it's working state, ..if you listen to it, it does sing when it gets mashed together. ..it's very quiet though, it may get cut out by the video encoder.

..if it will let me post them.  http://www.overunity.com/index.php?action=tpmod;dl=item253

@jedaro, I will check it out in a bit.

@All,
I decided to re-test the MK1. Remember this was the first one to light 30LEDs off the secondary/pick up coil.
I used the 'filter' toroid material
2N3904
a cap below the base transistor to smooth the pot. R=2.5Kohm
I never wrote in my notes if I used the 2 sides separately and I was never sure. So, I just did that part of the test over.

btw, ALL these measurements include the 9.5ohm resistor coming off the battery. I just can't be bothered to remove it at every step after checking amps. sorry.

16mA     bjt no light 
17.6mA  bjt w/led in jt position  -- this one went up!
8.9mA   52turn secondary/pickup 1 light
9.0mA   52turn secondary/pickup 2 lights
9.1mA   52turn secondary/pickup 3 lights  these also went up according to the leds added. (sorry the 30 lights are put away!)

30V Rectified no leds
13.8V Rectified led going one way
  4.0V Rectified led going the other way

This is all as in January

Then I separated the 2 ends and used them as singles

each half rectifies to
19V
and each side the rectified volts goes to
2V with led going one way and
15V with led going in the other way.

So, connected they are less than the sum of the 2 wires.

I wonder if the explanation for this is the same as the explanation for why Gary couldn't light a cfl even though he had enough volts.

thank you,

jeanna

@jadaro

I still don't see anything interesting about your setup, i did see that before , i don't see where you can improve to get results comparable to mine .
