The Master Of Magnetics "Steven Mark"

Sparkman,
  I don't know anything you can tell us about inductor to inductor resonance. I can intuit a couple of things. It takes three caps to make a oscillator so each provides 60 degrees of phase to give the 180 degree feedback and I know inductors are 90 degrees so it would take 2 of them. Also internal reactance between wraps need to be looked at there must be some capacitance between wraps at certin frequencies. Remember Steven saying generate noise. I believe he wants us to mostly ignore this part but I think we should get a little background from somewhere. I think this is basicly where the noise comes from. I got a 1935 electrician's handbook, nothing in it, I'm still hunting, I'm trying to find a earlier collage text book. So yes please anything you can tell us. I am sorry about the amount of time it took to respond. The group I work with here drafted me for interlacing wire. I haven't been on their project because I have had bad experiences with ZPE in the past. We worked out a way to twist shrink wrap and made some very long wires. I got a feeling they are twisted to loosely 4 miles came down to 3.1 by my odometer, what do you think? Did they screw up.

cOmster,
Nice video

Do any of you know were I can get mutistrand insulated mag-wire. I tried to get some friends at Sun Electric to make me some and they are not allowed to run anything but copper through their dies. I got a couple short pieces out of an extreamely old doorbell so the stuff has been made once upon a time... Thought you'd like hearing that.
I got 2 very large caps out of it too. Well I'm getting way off topic so. Oh, forgot to mention the little pieces I do have have insulation that's probably illegal in all 50 states.

This is not clear to me. Do you want copper magnet wire of the LITZ type ? This is available by many suppliers on the net. Do you want iron "magnetic" wire. Try contacting a thermocouple supplier such as OMEGA. They sell stranded iron wire which, with Constantan as its mate is used to make a type "J" thermocouple.  You should be able to purchase the iron wire separately but the individual strands will not be insulated. They may also sell single strand insulated iron wire.

Regarding oscillation, a tapped inductor or transformer gives the required 180 phase shift necessary for oscillation. When the gain of your circuit is greater than one at the frequency of interest and the phase shift equals  180 degrees, the circuit will oscillate. This includes the voltage gain of the transformer or tapped inductor. Two inductors in proximity, one driven, one as a feedback device will oscillate when the above conditions are met. They can be thought of as a loosely coupled transformer, and you may have to rotate either one 180 to get oscillation to commence.

Most homemade single transistor oscillators will find this sweet spot by themselves.

I do not know what your intentions for the twisted wires are so cannot comment.

I was reading some Tesla again and had a thought about his analogies with energy and hydralics, and found something interesting. A paradox I believe-one we can utilize,heres the analogy I made up.
-You have a bathttub full of water and an empty gallon pail.
-Put the gallon pail in the tub and fill it, lift it just above the water line.
The work done is clear enough acording to physics- liftting 1 gallon of water 1 unit in height. But here is my problem, If removing the water requires 1 unit of work, Why do you get 2 back?
Yes 2 units- you have created a void in the water where the bucket scooped it out, the inflow to this void is 1 unit of work, and you have a bucket full of water at 1 unit height which required 1 unit to lift. The inflow plus the gallon of water you have is 2 units work.
I know it doesn't work this way- But it does if the gallon pail moved at the speed of light-Like electricity? The tub is ambient energy, the pail an inductor pulse charged, we have never recognized the void inevitably left behind a moving charge. We can harness the energy moved(water lifted)-the pail of water poured back(Bemf) but what about the space occupied by the energy we moved? wasted I think?
Very strange indeed

91 volt version:-

-banana plugs installed, use this to configure different setups with coils, plus addition of plug in fuses.
-Frame cut in half to make it easier for winding, then attached again, bifilar windings used for now.
