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 .

I've got your mk1 and mk2 -how to- picture, what I don't understand is the winding.. does it go all the way around or are there more than one pickup coils?

I've got your mk1 and mk2 -how to- picture, what I don't understand is the winding.. does it go all the way around or are there more than one pickup coils?

The mk1 has 2 coil one on each side , not going any where but up and down on one side , the same on the other,
Mk2 has 2 on each side mk8 8 on each side. And stop trying to picture it and look at some pictures of it .

because the are some . I will not make a pdf , because its not for every one , people that think about making money before helping others get it , just don't get it , all the info is in those 150 first pages , i have read my self every post many times to make sure i understand what people are trying to say , and don't go to the next until done .

You do have some great idea , and are a good worker , but in my views you are not really giving anything new or even worth my time , sorry for my honesty. I am getting all the results i have stated any thing i do works , great but that is not the goal . So far there is more energy coming out then go in , and i don't use any tricks like hv caps , or bemf hmf
or what ever is fashionable on this site . Its just a regular step up  transformer but a efficient one .

The idea behind the helmholtz setup is that the coils are independent of one another - and you may not see much in the way of improvement for that, that's agreeable all together, the idea is that they're as independent of one another as your coils - being across from one another, however mine are separated by air and this makes it more difficult to add any pickup coils.

Additionally, we have the issues of the toroids emitting radio waves and sometimes sound.

When was it agreed that there was more output than input?

Why not just turn the thing on itself and have it power itself once and for all.

Or will bright lights cause it to malfunction?

Is it OK to remove the paint from these things? anyone know?

yes and no

yes: it won't make any differences on the way it work if the paint is not there.

no: the coating is there to protect the wires from sharp edge and protect from short circuits.
      wire can move during operation(buzzing sound), with enough time, it can wear off the varnish off the wire causing a short.


be cautious about your resistance reading of some of your toroids.
you might think a toroid surface is a nude surface, when in faq it is actually varnished.

drill a small hole or scratch, about .020 ~ .060 mil deep, on both side, then take your measurement from there.


again.
high permeability = the degree of magnetization of a material in response to a magnetic field.
it is complex when frequencies is involve, but not that hard to see what is happening.
http://en.wikipedia.org/wiki/Permeability_(electromagnetism)


for those who say ferrites are the best.
                            permeability                     frequency
ferrite (nickel zinc)  20-800 × 10-6 H/m  100kHz ~ 1 MHz
ferrite (manganese zinc)  >800 × 10-6 H/m  100kHz ~ 1 MHz

that mean ferrites coefficient of coupling is at it highest when at ~550 kHz.
lower frequencies then 100k or higher then 1 MHz make the coefficient of coupling drop drastically.
it is the coefficient of coupling that determine a transformer efficiency

at what frequency is your jt working ?

@MK1,
When you put the pickup coil on the toroid for tuning do you also put all the ends in series? or do you just use one of them for the tuning?

I can go to the MK2 I made yesterday and possibly take away or add another turn and see if I can improve on the end voltage.

I am also wondering if you experience this deep loss of voltage really twice what it should be when you have a load?

I understand the polarity thing with the leds, of course, but when the pick up is running the led and I am still looking at the rectified voltage, I watch this voltage go down by 6 volts. So, as unexpectedly as the volts are high, they are also dropping off at a high rate.

Have you seen this?
Do you have a remedy for it?

thank you,

jeanna
