Bad ass man!Originally posted by evostars View PostYes! doing your own research gives the best insights.
For your point 2, I wondered about that. With a simple switch in the connection, you can cancel the magnetic field. If this is used in a bedini type setup, then you can pulse it, create a magnetic field, push/pull a magnet. then when the action becomes unwanted (magnet passes over) you can switch the setup, and cancel the field of the coil. But I never tried this. It sure looks like what bedini's setup is all about. switching the bifilar coil.
Myself, im not interested in moving magnets. I'm more interested in non moving solid state.
The bifilar coil at its resonant frequency produces a dynamic field.
I just did a test, and blew a uf4007 (1A 1000V) diode. It was in the 1500Vdc setup. I was connecting my meter, to the diodes, when it exploded.
I blew out a single LED the other day and it was quite rewarding. I also blew out some opto couplers, that was less rewarding, now I have to wait on more parts...

Damn!
I had no IDEA! Now I've got another set of things to mess with in regards to the bifilar, thank you!Originally posted by Allen Burgess View Post@BroMikey,
I want to stress that the following comment should be disregarded for apparent reasons: The Tesla serial bifilar pancake coil was suppressed because it served as an EMP directed energy weapon, with top secret classification by the U.S. War Department.

I know this is nothing to laugh about b/c it's 100% serious, but LOL!Originally posted by Allen Burgess View PostIt occurred to me that evostars Hi-voltage pulse tests may raise eyebrows in the defense sector. There are MIB's out there!

Turned out, both diodes were broken. only one blew up. Pretty strange. seems the charge in a capacitor can move around really quick.Originally posted by ET-Power View PostBad ass man!

I had the system running (caps charged) but had forgotten to attach the dc meter. hooked up to the positive first. noting happened. But then I hooked up the negative and BAM.
Luckily i bought more of them at the same time. So i didn't have to wait on the postman.

Indeed the magnetic field should be confined like that. great suggestion. I would start with only a flat cylinder in the middle.Originally posted by Ufopolitics View PostMy pleasure Evo, I am glad I have inspired you!
OK, a ferrite or any other ferromagnetic material like plain iron, in a rod shape does not "adapt" to a Pancake Coil Generated Field, what you are doing by using a longer rod than the small thickness of your disc shaped coil is Elongating-Stretching the Field to a Spatial Dimension where is not being generated (nor strong)...and it does weakens your field and messes up your interactions.
You should try Core design by keeping the same Field Geometry that a Pancake generates...a disc shaped center core plus two disc cores I believe would enhance your field. And you could use some very fine insulation sheets between iron disc and center core plus wires...a center screw-nut will hold everything together...just an idea.
Very interesting...plus I see by watching your first videos that you have a pretty good idea about "visualizing" the invisible magnetic fields...and that is a Big "Plus" you have.
The "trick" is by moving (in any geometrical direction you could think off that could be done) your dielectric field...displacement of this field will cause displacement of the main polarizations as well...
You are completely right about your dielectric field in your coil...very good!...it is like a very fine membrane between the wires...

P.D: Don't be too confident about your small compass readings...they tend (a lot) to swap polarities, or reverse their needles magnetization...make sure you walk outside with it...and verify your North-South positioning is fine.
Yes visualisation is one of my plus points. The videos show the (DC) fields, but there is more to them. they also spiraling (you and I know how from ken wheeler and the ferrocell I guess).
About the dielectric field. it is indeed between the wires. But, thats in a DC current situation. with ac at its resonant frequency, things change.
Im still in the process of understanding what happens then (i want to make a video about it).
I seems the dielectric lines up with the magnetic field, and becomes one(magneto dielectric). The magnetic field is still there, but the dielectric field, is all around.
If I have a metal plate, completely removed from the system, and i put my oscilloscope probe on it, It reads the same sine wave signal. So it seems the field is expanded outwards. Even when I dont touch the wires with my probe, the signal is already there.
This is why I focus on the dynamic dielectric field.

I thought about how to extract energy from a high voltage system. As that is a tricky thing. It all needs to be tuned. In the attached drawing I used 2 pulse transformer, to generate AC on the secondary.
Don't know if this would work, but it would be a way to transform the high voltage into low voltage, high current.
The spark gap, would also be part of the system, I believe it should be in the center of the bifilar coils, as that would return some of the spark energy back into the system.

I really need a proper lesson in high voltage safety before i proceed.
Has anybody got a good link?
I just got shocked by my capacitors. I thought they where discharged.
after discharging the diode side, of my 4 series connected capacitors, there still was a charge left from the middle capacitors.
Doesnt make sense to me. but apperently you need to dicharge all capacitors separate, when they are in series?
Luckily I know the one hand rule. it discharged via one hand. So not through my whole body (heart). It gave me a good laugh, and a proper warning.

I replaced my variable tuning capacitor with a 200pF capacitor. It only has a 100V rating, but its in the resonant frequency coil, where there a re standing waves. The voltage over the cap is around 450Vac at 482kHz and it seems to work just fine. Its for tuning the coil
