I did not see the crisscross winding in this picture, but your picture clearly shows it.

So how do we wind a crisscross pattern and where does L1/L2 go?

Is 007's coil pretty much identical to Daniel's except for the six shorted windings?

Crap. I'm sorry. No it's not crossed. I was just using it for refernce.

However. Manny cools need time explored.

I'm about to start twisting wire. Need to calulate the wire twist. How Manny extra feed doni need of I do 1twist per inch.

Feels to much. Might do only 250 turns or somthing.

Good thing.  I was worried.  I like how you wound the toroid with the power cord.  I sure hope that's how it will be with the final configuration.

I think 1 turn per inch is WAY too tight.  You'll bust the enamel off for sure.  I would not go beyond 1 turn per three inches initially unless you have some very strong and flexible coating on the wires.  So 100 turns for 300 inches of wire.  If I'm wrong, you can always pull it off and spin another 50 turns and try again.

The other thing that will help immensely is to spin the wire vertically.  No, you do not need a tower, but if you have one, that makes life a piece of cake.  Without a tower, you will have to spin the wire in sections using round rubber clamps with an external drive mechanism.  Might be a bearcat to do this properly.

i can't wait to build this. this was on my list to do!
thank you guys for sharing the coil form.
saves me a lot of time in 3ds max.... :)
BIG THUMPS UP to matt watts for the design.
as i see the picture from russ.
she really is a beauty!!

not that this is that helpful but its interesting, resistance or coil dezighn? i ether way 5 1/2 hrs run time compared to 10 min is a segnicifent result...

there should be a way to calculate the initial charge of the capacitor and charge losses of the plain capacitor over time, calculate maximum power available from that charge and measure real power consumed over time for the led and the transistor and the wire ...

... and then calculate the difference :)

well. I'm tired. Its 2am. But it's done

I'm thinking something not quite right with the wire. If 007 said 15 ohms. I'm not sure where he got that.

Any how. This is 22awg. 28 feet 12 pair bundle.

230 twist. It un twisted 18 times. So we are left with 212 ish turns. Lets make It 210.

The wire shrink 4.5"

So we are left with 27feet7.5inches

That's 331.5 inches.

That's
0.6334841629
Turns per inch.

Anymore and it's a bit to much. Wires wanted to do funny things if I had gone more.

All wires must have same tension or loops will form.

You can see some in my photos.

Well it's 2:15. I'm showering. Lol. So here you go.

We need to think about the ohms. We know the wire length now.

Also there is an art to winding thses things. But. I have 1 under my belt. :)

:cool:

:huh:

:D
2:28. I'm so tired.

cool man,
finally did it!!!

Good work Matt. Those look good. !

Also the extra holes in the ring you should add as well as a center one in the former really make it nice to zip tie like I did... Sure. Glue. I know.

Any how. Good guesses guys. Vac cord is 30 foot.

Real mesurment is. 293.2"

So if we make our wire 25 feet we should have enugh to still work with on the ends.

However. We must include the twist.

 I'm still calulating the number of tunrs per inch for the wire.



So we need like 26-27 feet the twist will shrink the length some amount.

So 27 foot x 12 for L1 and the same for L2

 324Foot. For each coil.

A lot less wire than I thought.

It sure puts a smile on my face to look at that coil. Its neet to see a torus come out of this simple jig.

~Russ

324Foot. For each coil.

is that 324 foot for the 24 strained coil (do this twice and you have the full coil)
or is that 324 foot a strain?

doesnt your second coil suppose to go the otherway?

or are you trying a different design?

props on the build anyway!

russ youre an animal. nice work !

i understand fretting about the wire twist dynamics.....sort of. if it ends up being pointed at as a weak spot in the build it will be very discouraging....i mean.....should the enamel on the wire also follow some sort of molded spin? where does the practical stop and the imagination begin?
also, the direction the wire is spun.....if it is twisted the wrong way is that going to impact performance?

anyways , i look forward to exploring these questions soon.

Also on it now. Three forms printed now. Not perfect looking but it will do.

Got equipment to measure LCR, QD etc at 100Hz-10KHz as well as impedance and phase (via waveform gen and scope) from 0 to 1 MHz.
Audio amp is ready as well as other square wave drivers/waveform generators. HHO cell is also standing by, waiting to become alive .. :-O
I hope we get some details from "007" soon.

Probes are in.

alright! looking good! ( nice delta) :)

what kind of amp do you have? whats the driver circuit?

~Russ

ok i extracted some coil I'm mages from the BEM footage,

can some one with Photoshop skills try to over lay my coil make them transparent so we can see how different thy are? if some one starts this task can they please tel me they are working on it,  would be nice :)

Thanks!!

Russ your coil looks kick ass!! I'll see if I can do the photo overlay for you.

taking a quick look, i notice tons of kinks and irregularities in his coil....yours looks more uniform by far

The only thing I notice is your coil looks larger than 007's.  I tend to wonder if the 27cm/9cm dimensions were really correct.  Maybe all the way to edge of his bobbins, but surely not to the centerlines where the wire actually sits.

If you had one of those exact same current loops, I'd like to see how it looks on your coil compared to his.


Also, do we have a handle on the resistance?  Just going to run it as is and see what happens?


One other thing...

If your coil is too perfect, please don't blow yourself up at home.   ;)

Russ - here are a couple of comparison images - side by side & transparent overlay from similar angle. I reversed your image as they are wound opposite directions. Otherwise amazingly close.

Oh crap!   Russ is building an energy sucker instead of an amplifier then.    :rofl2:

Oh no! An electromagnetic black hole!
