hey bubz,

you say that this coil will work in 2nd , 3rd harmonics and any spectrum harmonic to its natural freq..

i want to share a perspective thats been on my mind since yesterday...

imagine you are spining a merry go round.. each time you grab it to add energy with the motion of you hand to apply it..  we will call the grab point a and the release point b...  a is 0 on the scope while be is the max potential reached in the form of distance..   pretend there is a flag on one ofthe post on the mery go round so you can keep track of cycles.. now  one must acknowlege that if the merry go round is lets say spinning at 4 cycles a second, unreal i know but lets pretend.. that would be equivalent to 4hz  you being the energy source providing the acceleration to it do you have to add energy ever  hz to maintain its momentum... no you could add a burst every 4th to maintain speed and hz... now  if we are only feeding it energy 1 out of 4 pushes maintaining 4hz. what will happen if you didnt change your repittion of when you apply energy  but rather you change the speed of your hand that is applying the push... that would mean you could add energy at 1 hz but could still manage to continue to make the marry go round speed up into higher freq.. i think this is a good example of elongating electrons and how it is posible to apply a low frequency and generate higher freq..   amplitude and sharp rise time in a pulse is like the speeding up of the hand from point a to b... aka particle acceleration?

Bubz,the coil you posted the picture of I have seen first hand.It is made using a Magnetics EC52 type of core.Can't say what material for sure,but there were Magnetics E cores there in the stuff I seen.There were 4 rows of bifiller wrapped copper wire on it.There was thin cardboard between each row.Each row had @ 14 turns for each wire(28 turns total per row). So each wire had @ 56 turns.The wire measured .0425 inch.This coil was hand wrapped.Both wires were wrapped at the same time side by side just like the drawing.The wires ended on the same end they were started from.The start end of the wires went to the cell,and the finished ends went to ground on the pulsing circuit.
Hope this helps everyone interested.
Remember this set up was for the variable plate cell.

Thanks Bubs!
For everyone else, take a look at this:

Thanks Dynodon for the choke description

"3 phase windings:
3 coils per phase connected in series
of which two end-coils are bifilar wound
and all three coils wrapped in the same
direction..."


"3 coils per phase connected in series" 
Pos/Coil1(choke)---Coil2(secondary)---Coil3(choke)/Neg

"Of which two end-coils are bifilar wound"
The end-coils are the two choke coils 1 and 3 wound together.

"All three coils wrapped in the same direction..."
We can use the right-hand rule. When the coil is viewed wound away from us, the winds are to the right or clockwise.

A few tidbits...

Stator coil windings:
Longer wire = more turns = higher voltage
Bigger wire = less turns =lower voltage/more current
Smaller wire = more turns = higher voltage/less current
Double the voltage = half the current
Double the current = half the voltage
Adding laminations to the core = higher voltage
WYE = series = higher voltage/less current
Delta = parallel = higher current/less voltage


Thanks everyone for the great posts!

Yea! exactly, what stage of the game are you for building it? If I had 10 hours of free time I'd be winding it, stator is ready to go, would love to cooperate with you if you're going to try this.

can you describe how it starts and ends at the same side of the coil? i am not sure how to visualize this, thank you

I think I have beginners luck! My cell leaks faster than I can fill it, but I can get up to 8-10psi in under 5 minutes. Had witnesses and took some crappy pics. 16 watts input power @ 8V 2A...
