@ Wilby:

Thanks.  I have several places I found online but I was looking for a local supplier so I could "hand-pick" some of these.  This device is so cool.  I can't wait to see your replication.

@ Jonny:

My neo spheres arrived yesterday.  I did a few quick tests and, even the 1/4" spheres spin too fast!  (I got .750, 5/8" and 1/4" dia.)  Even with all of the resistance off, it stays in the center and really winds up and then........look out!  I had one fly off and hit my fridge across the room and it put a small dent in the door!  It was like a bullit.   For the small spheres, I may have to lower my base resistor value from 100 to something lower.

Great video!  I can't believe it runs on som low a mA number.  Great job.

Hi Bill,

I think just the other direction:  you would have to increase your base resistor to reduce the collector current so that the sphere magnet should rotate with less speed, hence they would not launch... 

Or you mean the small spheres need more collector current to spin faster?   I miss something?

Thanks, Gyula

Gyula:

I may have that backwards.  I will have to put my meter on the pots to check it.  I know I have these pots wired backwards from my Bedini so I may be confused.  Thanks.

Here is my latest video on this:

I am using smaller, bench tested magnets supplied to me from a good friend from overseas.  These spin really well.  The fun begins.....

took a break from winding a new tesla secondary and tossed together a quick testbed to see what 'type' of spinners i had. it looks like i got lucky, i have one that runs close to perfect vertical, and one x wobbler. i used a really small coil, no adjustment pot, and ran it at 9v input. it spins, but nowhere near the revs you guys are getting. will post a pic after i pretty it up a bit.

Wilby:

Glad to see you are replicating this.  This is one of the coolest things to have running right in front of you.  As I found out, the magnets make a huge difference in running attitude...lucky for you have have one that goes vertical in a steady way.  If not for Jonny, I would be stuck with my X wobble.  I did a pretty nice job tonight on mounting a computer fan (turbine) onto one of the eggs.  It was well centered and well balanced but....there is a metal ring on the ID of those fans, (after you remove the magnet) and I decided to leave it as I might have damaged the fan by removing it.  Well, big mistake.  I got everything else ok but the metal messes with the field and it spins, but does not even go near the center and when it does....it flops over.  I tried every setting I have but it has to be that metal in the core.  I will try removing it for next time.

There are so many things we can do with these.  I am taking Jonny's suggestion and after modding my circuit like his, I will try to run it on the earth battery....which is now up to 12 mA's as of just a little while ago. (@1.96 volts)

I hate it when an experiment does not work as planned but, that's the way it goes.

thanks pirate. yeah it was pretty sweet to see it spin right away. i used one of those 'perpetual motion' toys. has a little kicker coil in the base, no adjustments. now i need to do a proper build. your fan sounds interesting. you might discover a 'new' kind of magnet 'lift' with that  ;)

@ all
do you guys think a u shaped core, with enough separation between the two poles, would spin two magnets?

@WilbyInebriated:

The 2nd magnet would have to be brought in at the exact speed and phase of the first magnet onto the 2nd core-end
or it would interfere the first magnet's push from the transistor.
I guess that is close to impossible.
Even if you would manage somehow to do that, the amp-draw would simply double, no real benefit in using two magnets hypothetically.
To understand that, i recommend watching this MIT professor explain how this magnet motor works:

The magnet and the transistor work together in sync.

I had to play a little last Sunday. I wound a 26 guage coil around the plastic jar to check on electric generation. The coil was only about 60 feet of wire - did not count the winds. The coil produced a small voltage when surrounding the magnet and also when held outside of the magnet at a 90 degree position. The interesting part was the jump it took when held at about a 15 degree angle as you can see in the video.

Perhaps Xenomorph or someone else could see if holding the coils similarly to the vid increases the volts. Mine went from .2 to almost 4 volts AC.

Here is the link. http://www.youtube.com/watch?v=kqO9WNnb0Gc

@ brownsville:

Great vid man.  I don't know why this could be.  I too will try this.  I have tried a roll of 30 ga. mag wire and could not get much at all out of it.  I will post my results.  Great job.

As Gyula has pointed out earlier in this thread by providing helpful links, the pickup-coils need to have a very high turn count, very thin wire, a comparatively big area  and a small coil length to maximize their output.
Just a few turns wont give you a significant output unfortunately.

I have just experimentally concluded that even 2000 turns is not enough ! (depending on what you wanna do of course)

I want to remind people again that Lenz law is in effect when inducing currents in pickup coils and powering something with that current.

@All

Saw this video today which is somewhat relevant as its a no bearing one magnet:

"Fast Motor 150.000RPM no rotor neodimio magnet"
http://www.youtube.com/watch?v=m1WkxHr0G6o&feature=related

This thing really spins fast using a round neo inside the coil  :o

Paul

Yes, I saw that.  That thing is really spinning!  That video is the reason I purchased my 5 different sized neo spheres but, I can't control them once they really start speeding up.  They fly across the room like a bullet.  I think he mentioned he is using 2 coils.  I can't figure out what he meant by that.  Also, I noticed he didn't have to spin it up by hand like we do with our set-ups.  Maybe his second coil helps with that?

Pirate, I've looked at the video several times now and it's very hard to make out because he mentions having two coils (in what configuration we don't know) and also mentions "Similar Bedini" circuit at the end of the video as well as the information section.

The English translation seems a little different than the spanish one....

"150,000 Rpm Motor fast without a rotor made of Neodymium magnet ball 2 reels of 8 mm (as a trigger and as a promoter) and a Bedini circuit similar."

PS: I don't see why one couldn't add a clear plexi at both ends of the air core to prevent the ball from coming out and flying across the room  :o

Regards,
Paul

@ Goat:

Your idea would work with his set-up but on mine, it is just spinning on a flat plate.  Before I glue my plate on, I tried his way inside the coil and it would not spin.  Even with me hand starting it. He must have done something different, I don't know.  I love the sound though.
