@ MK 1:

Wow, thanks for posting that.  That item is a real piece of history.  Was that the version made in England?  Or did that come later when the US started getting into radar?  Most of the younger folks here probably don't know that the first microwave ovens were called "Radarange", and for good reason.  Thanks again.

Bill      PS since radar was developed prior to the transistor invention, did they used vacuum tubes for the high speed switching?

This is where i got it,http://www.dkimages.com/discover/DKIMAGES/Discover/Home/Technology/Electronics/General/General-065.html
And other interesting fact is the speed of light factor is archived at 99 percent by our good old microwave oven.

It had to be tubes,Tesla did not have that luxury he had to use motor and brushes to archive switching and timing, harder to make at first be i think it would be a more intuitive process then working with transistor and timers, but not as fast or efficient .The transistor came in 1947.lol 

Young people only know what there told, tv closes the loop so not many go beyond , i know i am one but shit started backing up to a point it could not go on, Work needs to be done and cant wait for the Savior to come bail us out it wont.

i love the pic of the magnatron 

a few mods to it lol and you got my NEO G UNIT 

ist!

its a big world  ......  and  well it is teslas work

oh yes  it is HEMF LOL call it what it is

song time agin .....   little bit of red need more marker ??

@ Norbert

Well Well Well, what have we here, take a look every one, here is the 1st time this forum has seen a working example of an "airless" jule thief bifilar wound coil. I am impressed, and the photo is good also.

IST mentioned in a couple of his posts that this could be possible, the last pic shows many white LEDs working.

Norbert, this is impressive, congradulations.

You mentioned you have replaced the resistor with a adjustable resistor, again well done, I had thought of this myself but didnt have one so didnt worry about it, you beat me to it. Having a variable resistor here will give you a bit of "control" over what the JT can do, I suppose it could be see as a fine tuning of the JT.

OK, lets get down to the reason you posted.

your voltage goes up and down when you alter settings,.
This is to be expected, as you change something ever so slightly, it will change something else, if the light flickers quickly, this may mean a crook connection. First clean your contacts on the breadboard, then the wires that poke in the small holes, see if that fixes the problems.

The JT is running on the energy inside the rod (magnetic field), when you pull the rod out it is seeking the energy from somewhere, so I think it begins to feed off it's own energy it creates when the rod was inside the coils. So it seems to me the magnetic field produced by the bifilar coils can be utilised without the rod being there, as the field is in existance, energy can be drawn from it as long as it exists, hmmm 
Has anyone else got some advice for Norbert?

This topic constantly amazes me, something new every day.
Now I wonder, could a bifilar winding be put on a toilet roll? hmmm

jim

if you go back to the begining of the thread i posted an aircoil jt long ago, to demonstrate that a core is not absolutely necessary. it was a coil from a crystal radio i built. yes you can use a toilet paper roll.

@Artic_Knight

You've been here for a year, asking many many many questions, and thanking others for their help, then you
go all boastfull and cryptic with this:

modern science cannot explain what i am doing. when i am done, cellphones homes and cars will be fully powered by a powersource in the palm of your hand or in a cell phone battery   

of course youll need a couple "batteries" for the car but they will be so tiny its neglidgable.

Are you here to help or annoy? Please contribute or go away ...

@all

If you poke at a 'hinter', will it change it's ways, or will it ignore you?
