Hi.Here is the circuit i am using.The relay i am using can be seen in the picture 2 posts above this one and if you look closely i am only using the relays coil.The way i made my coil was i bought two rolls of 26swg wire.each one had 250grams off wire on and was 170 meters long.I wound these onto a spool i got which had speaker wire on it.I made it like this as it is easy if you start off with the same lengh off wire for each winding and it seems to work good.The standard Bedini coil and lidmotors coil should work just as well as other people have replicated with different coils.It is important to put both variable resistors in.I have the 1k one turned right up to 1k and i just leave it alone and adjust the speed with the 10k pot so i could replace that with afixed resistor but your circuits may behave differently so you want this as a tuning option.Another benefit of adding the relay coil apart from reducing the amp draw is that you can recover bemf from it with a diode and cap.Hope this helps regards jonnydavro.
Jonnydavro you reported why your coil looks so different than a radio shack coil and 170 meters equates to 558 feet per wire . I think this is why you can run it so low on the volts . Do you know of  anyone who build a lidmotor style coil that is running this setup on 1 volt ?

Al:

I am running mine on the Lidmotor coil and it works fine.  It is very efficient.  I have not added the mods that Jonny has to get my power requirements lower.  I believe he has added a cap and a relay to do this.  This is my next step.  But, mine did run from the EB/maxcap at 2.3 volts so I am not that far away.  PS  I love your cap and I am so glad I purchased it.

Hi.I have done a few tests with a  joule thief circuit and the joule thief will light the Led from 9" away from the main rotor,i have enclosed a pic.For this test i had the satellite running in a top from a washing up liquid bottle,the type with a plunger and it works really well.
Regarding lenz law and this setup.Lenz is alive and well but that does not mean we can't run lots off satellites with loads without stalling the main rotor.From what i have seen from my setup the main rotor can spin many satellites and its just a question of ballancing the loads you place on them.There will be a point when the lenz force from all the satellites will stall the rotor but there is one thing people are forgeting here.We are using a Bedini motor so as rotor speed decreases,so does the amp draw.With the free roaming magnet i am using the ampmeter does not stay still for long but in limotors latest vid,with his stablised Top,he shows this effect with his circuit.

http://www.youtube.com/watch?v=V1pV-zHUWck

I measured the current in series with an Led today and at
 2" from the magnetitwas 2.6mA
 3 1/2" 1.8mA
 5"  1.3mA
and the current decreases as you move outwards but like i said earlier in the post you can still run a circuit at 9".Regards jonny

@ Pirate . thank you Bill for responding on the lidmotor coil . that is encouraging that it runs from the monster cap :) I am Glad you are finding good uses for it. I also love those ultra caps . theres nothing like them . Have you tried the satellite balls ?

@jonny
 Hey that is Great information and thank you for taking those Measurements . a bigger pickup coil should produce more amps . and 4 more pickups should equal the input . Yes Bedini's are very different "motors" . in that the spin is free . the pick up might not be .I can say without a Doubt that Some Bedinis are OU . and i like the one volt battery setup you have .  AA's are cheap compared to 12 volt sla.s or 9 volt . I wonder what you will think of Next  ???  :D also Concerning your red washing cap  have you tried to put a little soap in it and see if it spins faster ?

Thanks to Jonnys tip with the dish soap cap, i have a stable spinning satellite magnet going now.
http://www.youtube.com/watch?v=QIe2cNCNC3Y

The voltages i can pick up though are far from what Jonny is getting.
It boggles my mind lol.
The only factors that can make the difference are:
His main rotor spins 7 times faster (which is unlikely)
His satellite magnetic field is 7 times stronger (Also not, his is N42, mine is even supposed to be N45)
His pickup coil has 7 times more turns (Mine has 7k, so his would in this case have 50k, very unlikely too hehe)

I use AWG 32 wire (0.2mm), going thinner would not deliver enough current was my thought.

Anyone has another idea?


I also reduced the system voltage to a single AA battery now, so it runs ar 1.2 Volt @ 7mA which is veeery nice.

@Xenomorph.Great vids mate,nicely done with the single AA @7mA.That is very very little power.
Ok pickup voltage.Wire size is very important for pickup coils,thick gets you more current, thinner gets you more volts.I am using 40swg which is a lot thinner than your 32swg so thats one difference.
My pickup coil spool is from a roll of plumbers PTFE tape,dimentions are 52mm x 20mm with the centre hole being 25mm and is about 3/4 full of wire.
Also try running your pickup and satellite on the surface and not elevated to the same level as the rotor and now thanks to you i rechecked my earlier voltage test and made a chance discovery.
This is what i found.This  test was done  at 2.8v,With the pickup coil conected to a bridge rectifier and then to the meter.
With the satelite 6 1/2" away from the main rotor.If i just place my satellite into the pickup coil it will generate quite high voltage,3.2v.See pic 1.
If i tilt the satellite slightly and move it around against the side you can find a position where the voltage starts increasing(7.31v) so then you wedge it in that position with a piece of cardboard see pics 2 and 3.
So basically efficiency can be increased a lot more by reducing the friction in the satellites but i think its a combination of the things i have mentioned above.The voltage is there,you just have to tease it out.Hope this helps regards jonny.

Hi.El-tigre from the energetic forum suggested and has successfully run an alternative satellite rotor consisting of a testube with a small magnet fixed to the bottom and then you can place a small rod or a bar magnet into the testube and it is levitated by the fixed magnet.I have replicated this.First i tried a 25mm x 5mm rod magnet in a 75mm x 12mm straight sided testube with a small feritte magnet hot glued to the bottom and it span but rotation was rattle and a bit eratic but this may be due to having to much wiggle room.I then tried a diametricaly magnetised bar magnet with similar results but without the small washers that El-tigre used so i will retest that when i can find some small washers.Then this morning i wondered what would happen if i used two 6mm neo spheres and boy was i shocked,this thing spins and not only that it levitates right to the top of the testube.I would be interested in any thoughts on that.I have not done any other tests on this yet but the rpm's are very high so i would expect high induced voltages.Here's some pics and a vid so you can see what i mean.Regards jonny

@Jonny:

I had not much luck getting significant voltages induced with the two spheres sticking together.
I believe that is due to the fact that their magnetic orientation is upwards and downwards and not perpendicular to their rotational axis. A diametrically magnetized magnet will solve this i hope.

Hi.Here is a vid i did of a test with 12 stable satellites in ice cube trays.They all self started on the initial spin of the main rotor.

http://www.youtube.com/watch?v=d4NrzeijnuY

@ Xenomorph.Hi.I have done a few tests including induction and at 3" from the main rotor i can induce 9.5v and at 5"-7.6v.This is with the sphere's at the top of the tube with my pickup coil at a 45 degree angle on top of the tube.If i move the testube further than 5",the sphere's stop spinning.I also tried without the magnet and it seems to levitate even better than with the repulsing magnet like you suspected.
To me it looks like the sphere's are rotating faster than the main rotor,i don't think i can get my tacho on it but if you observe it when start it it looks like it is faster to.What do you think?
There is still a lot of friction here as the sphere's are rubbing up against the side of the tube so thats something to think about.
Also i would suggest you use plastic testube's as i had 15 which i got for my small sphere inside the coil motor and i have broke 7 messing with this today.Regards jonny

@all

Congratulations to all that have attained any magnet replication but more to the ones that have attained the levitating magnets.

The problem of the circuit seeing a feedback to the source as a load and stop can be overcome by using only one leg of the pickup coil with one diode with the white band directed to the positive and connected to the source positive.  Or with the band looking away ot the negative and connected to the source negative.

Maybe I used to much words to explain this.
In other words, using just one cable from the pickup coil either to the positive or the negative, but not both.

Hi Jonnydavro and all,

I have limited internet access and recently looked at your thread.  This is a most awesome discovery!  If I am right, it helps solve problems in another topic, Steven Marks TPU.  Those who are interested can look at my post here:

http://www.overunity.com/index.php?topic=7611.new#new

I did not want to bring this up here and distract the current direction this group is going.  So, I decided to start a new thread suggesting that ideas being developed here be the basis and the heart of a TPU.  You may not know it, but you all are heading in that direction as you start to experiment with different collectors and frequencies of rotation. 

For those of you placing the magnets inside the coils or tubes I have an idea  that might work?  Try placing sheets of bismuth inside the coils or tubes and also on the bottom.  Bismuth has the unique property of being repelled by a magnetic field.  See here:

http://www.youtube.com/watch?v=hUoUSz-hD8A

Perhaps the bismuth will repel the magnet inside keeping it centered and prevent hitting the sides?  Maybe also help give it lift?  Just a guess hoping it works.  If one can not find bismuth sheets, I think the lead free shot for shot gun shells are bismuth.  You could melt them down and maybe pound thinner for experiments to center and levitate magnets?

Keep up the good work here and good luck to all.

@Jesus:

Tesla One wire-style? So do you think there is no current needed to do that?
After inducing voltages that are 2V above the source battery , my main concern
now is to reach enough current to feed back to the source (7-10 mA in my setup)
But if the one-wire impulses would suffice that would be SPECTACULAR.

I will try your suggestion for sure.

Would a bridge rectifier work too (just connecting one pole of it to the battery) ?
I was figuring that would make use of the full AC wave, but maybe not for the radiant spikes.



@tishatang:

Thanks for the Bismuth tip.
Theoretically that really could help confining the satellite magnet.
The fact that it is repulsing obviously North and South pole equally is perfect.
The satellite would then not rub against the tube wall AT LEAST not due to the attraction of the bottom magnet as we have it now trying to turn around and move towards it and thereby hitting the wall.
I assume the magnet will still rub against the walls more in a random collision manner like in Eroutt´s videos because the main rotor´s field will attract/repulse it towards/away from itself and thus moving it in the XY axis.
I have no idea where to get that Bismuth stuff, will look into it.

EDIT: Coincidentally a youtube subscriber just sent me an AMAZING link.
It is actually EXACTLY what we are looking for with the test tube magnets.
It uses Bismuth plates and it allows true levitation that will prevent the magnet from hitting the tube walls and insane speeds.
The guy in the video just gave it a burst of air through a straw and states that he has measured 100k RPM on his levitated magnets.
Here is the video:

http://www.youtube.com/watch?v=6g135HwcLZE

That technology could revolutionize wind generators as well. :thumbsup:

I have just tried Jesus suggestion with the one wire coil technique.
Unfortunately the source battery still runs down.
I first used one coil, the two in which i attached one to the plus and one to the minus of the battery (with diodes directed like he suggested)
In the end i even used 3 coils.
I am not saying that this might not work at all, just a very first attempt to do it.
Maybe Jesus has a suggestion on what to improve to to this succesfully?

I wonder if the battery has to be conditioned for negative charging for this too work?

Greetings Group, I'm following your ideas with great interest and I'm trying to make time to experiment as well. I got hematite sphere and "egg" working with one of my SSG coils. I'm still waiting for several components ordered for other projects but I have very curious mind :) Idea with using bismuth may be something! Just found this site - http://www.americanelements.com/bifoil.html  they have a bismuth foil, which would be easier to work with. Just an idea...
