I saw this video and thought of this thread...

YouTube - Levitation at 50,000 + RPM

A magnet levitating and spinning at 50,000 RPM and timed slowing down basic experiment by AVA Magnetic Levitation just for fun!

@themart:
Thats the same company that i posted the youtube link earlier.
Your video link shows it even better how viable this is for the setup discussed here !
This is really amazing stuff.
50 k RPM will generate insane voltages

@Jonnydavro:The circular Halbach array might work as a magnetic cushion for the glass tube spinners. Gyroscope.com - gyroscopes, educational toys and gadgets offers the twelve cube magnets and the ring collar for sale. Focused inward, the array projects a unipolar field toward the center. It might fit down over the tube like a collar and keep the spinning magnets from coliding with the glass wall.
@Retrod1: Thanks for filling in the blanks on your power data. Looking foward to an update. Also, Johnnblade demonstrates a speed up of his rotor mag by positioning a second stationary magnet in line with the roter and coil while adjusting the direction of polarity. Perhaps a paralell path field magnafication effect at work.
@Mile-high: Thanks for educating us with those fine points!
@Lidmotor: Looks like larger more powerfull magnet rotors may continue to pay increased dividends after all.
@Jbigness5: Tow a camper trailer in the back yard, and set the shop up out there.

el tigre ----stabilizer

@ El- tigre--- I tried you rotor magnet stablizer and it works. I did it a little different but the theory works quite well. I used a little steel nut taped to a bic pen and just held it under my plastic lid. It worked. Great idea!!

I ran my SATURN MAGNET BEDINI on a little 3.5 volt solar cell and capacitors today. Here is the video of it:

@ El-tigre.Hi.I think you have a real nice charging setup.Regarding pickup coils,i am seeing the same thing with the satellites,microscopic adjustments can make an enormous difference to the amount of voltage you can recover.The 45 degree angle on your testube satellite was imperative for a recovering a high voltage.
I was quite amazed when the 2 sphere's shot to the top of the tube.I think it could be a number of things which may cause it.
1.The magnets are corkscrewing up the tube.
2.The testubes may have a microscopic taper
3.Magnetic amplification
The magnets climb to the top of the tube no matter which direction the rotor is spun.I also noticed if i hold the testube at the bottom and apply pressure they will go down.
My initial impression is the magnets seem to rise better when the North pole is facing up but i will do somemore tests to confirm this.
You are sharing some great idea's lately,your stabilising idea being another which i will try and hopefully put to good use.Cheers jonny.
@Xenomorph. I have had a look at that vid and i think it may be just what we need.I will have to read up on Bismuth as i don't really know much about it but it looks quite amazing.Thank your friend regards jonny.
@Synchro I will have a look at that website or maybe i could maybe makeone as clanzer has been experimenting with halbach arrays and he has made quite a few vids on them so they may be good for idea's too.Cheers jonny.
@Lidmotor.Its starting to sound like an astronomy club here with satellites and satern motors Nice job.Regards jonny

Getting frustrated.

Hey guys. I love what you are doing... I know I am very late to the party (as my wife usually blames me for)... However, I have wound a coil and am trying to test all of this out. I am a noob at alot of this but have successfully done a modified fan motor... and a cfl fan motor... and a solid state bedini... but i love what you are doing with this project and am trying to replicate. No matter what i seem to do i can't seem to get higher than .2 to .3v on the base of the transistor. I have 2 windings... 22g and 26g at 200 feet for about 550 windings (give or take 50). I wound it clockwise and at the moment i am using 1/16" copper coated welding rods as the center. I like to try before bothering and have done everything that i can think of to try to get that higher. Could someone PLEASE tell me what i am doing wrong...

Rich

P.S. I have followed alot of the videos and i LOVE the work you guys are doing.

Coil design Variables

Has anyone experimented with the drive coil core diameter variable? I have observed a significant magnetic dead spot centered directly above the air core (and even my metal core) coil. (core diameter of 1" on both)

I expect that a coil with a much smaller core diameter will produce more stability in the rotation of the main rotor. My observations indicate that a rotor approaching the dead spot tends to lose it's magnetic coupling to the coil and suffers gyroscopic toppeling which causes the rotor to skid over the dead spot only to reengage the magnetic field on the other side. This could explain the seemingly random wandering of rotors and I suspect it may be cured or significantly helped,by reducing the size of the magnetic dead spot over the air core by physically reducing the core diameter. Maybe it could be reduced down to a millimeter or 2 and a single welding rod used as a core could double as a magnetic grapple for the rotor. This seems logical given the successful tests of magnetically holding spheres in place during rotation.

Alternately, a coil with a much larger air core may permit a large main rotor to be spun right inside the bifilar core? Has anyone walked down this road before I start rewinding things?? And is there a limit to how large or small a coil core can be wound before it ceases to drive a Bedini circuit?

Thx men, keep on spinning the magnets.

@Xeno

Thank you for the reply. I have check all of my connections and it seems that everything is tight. I have setup to jonny's spec except for no recovery off the 12v coil and a !n4007 instead of a 1n4937 off the collector. I don't have a 1n4937 available. My supply voltage is 12v. I have noticed something else that is occuring that is baffling me. If i turn the pots up to a total of about 2.1k it start to self oscillate. I have taken the core out and the same result. If I put a meter to check the voltage on base, it reads between .2 and .3v. I am using the snake egg magnets as that is all my financial planner (wife) would allow me for the moment. Putting to the side for some N42's. Any help would be appreciated.

Wow... now i am really not sure what to think... The snake eggs that i purchased came in a 4 pack... 2 oval... 2 round. I just tried spinning up a round in the center and my base voltage went to .8v and it worked wonderfully.... Still not sure as to why the snake egg won't come close to that with a bowl sitting directly atop the coil.

Just an update... any suggestions would still be wonderful...

Thanx

@jurmb84: That is good news.

Magnetic spheres are much easier to spin up than the snake eggs.
I usually had to use EXTREME initial manual force to give it a high speed when releasing it from my hands to have it start up.
I highly suggest that you get those diametrically magnetized cylinders, i guess thats what you meant with the N42s.

I am using the snake egg magnets as that is all my financial planner (wife) would allow me for the moment.

This thread is also very educating in regards to the different levels of para-governmental, domestic, matriarchal soft-tyranny.
These experiments can be a heavy burden to the budget no doubt, but what you wish for (the new magnets) will come to you !

Good luck

Manufacturing circular Halbach array miter box.

@Jonnydavro. I looked at all Clanzers Halbach videos, thanks! It should be very simple to manufacture a circular halback array. All you really need is the 12, 1-4" cube magnets and 12, 30 degree wedges. A miter box with a 15 degree slot for a back saw should be able to cut out the 30 degree wedges that would go between the cubes to form the circular array, just by flipping the 1-4" square stock over in the miter box. The box needs a 3-8" base. They could be glued into position, or fit into a holder. There are three ways the circular array can work. Field up, field down or field in. All you need to do is identify and mark the north and south poles on the cube magnets. South pole up, north poles sandwich facing in: North pole up, north poles sandwich facing out and so forth. You can draw out the 12 cube arrangement, and see how that pattern closes with that number. That sure beats 34 British pounds plus shipping from England. These circular arrays open up alot of possibilities, like two pointing out, one over the other glued together with a few popsicle sticks, so the tube can be lifted off the spinning magnets from the inside, and left confined inside the Halbach force field tube.

@El-tigre.I too have noticed a bit of a dead spot in the centre of the coil but when i run the snake egg "X" spinner with a core,it works best when centred but my other magnets prefer to be near the side so it would be really interesting to wind a coil like you suggest and see what happens.
@Synchro.Clanzer makes some great informative vids and the halbach array does not look to complicated so i may try and make one and build some adjustment in maybe.Thanks for the orientation info.Regards jonny.
@jurmb84 Hi.Thanks for taking the time and effort,not to mention the expense to join us in our experiments.
With regards to your motor,if it can run a sphere,it should be able to run the snake egg.I think your problem may be one of two things or both.
The first could be as Xenomorph mentioned the need for a real good two handed spin.How pirate and Lidmotor can start there's with one hand is a mystery to me as i have to use two.
The 2nd thing it could be and this is what i suspect is the problem is your core may be to close to the snake egg.The snake egg will be attracted to the core and it needs to stand upright but if the magnetic attraction between egg and core are to much then the egg won't spin up.I suggest sliding your core down a bit and see how you go.Let us know how you get on.Regards jonny

Dead spot explanation

Jonny Davro and El Tigre: Can either of you explain why there is a "magnetic dead spot"? Building a new coil is an attempt to work around the problem. What you should really be doing is trying to understand the problem, and then you may be able to come up with a better solution.

The challenge goes out to all of you: Why are Jonny Davro and El Tigre seeing a dead spot when the spinning magnet is close to the center axis of the coil?

core dead zone

One explanation might be that the magnetic field around the energized coil is shaped like a doughnut (toroid). The hole in the doughnut is the dead zone therefore, my idea is to make the hole as small as practical and the resulting magnetic field should then resemble a doughnut with a very small hole in the middle. If you can make the hole small enough that it can be filled with a single welding rod, then the dead zone can be used to magnetically fix the rotor in its orbit instead of having to avoid it by offsetting the rotor etc. Should result in more stable rotation and higher overall rotation speed.

Too bad these spheres rpm are so damn hard to measure with a tach. Maybe if we spray paint them black or use some gun bluing and scrape off a tiny stripe on one side we can get a measurement without causing an imbalance.
