Thanks a lot "THE ONE" for your answer I?ll use a 4" PVC piece of pipe and a Magnet that could be near of the coil, I?ll be in toch with pictures.
Thanks a lot!!!!!

foes the shaft tube have to be touching the magnets?
Thanks again THE ONE!

they can its not really an issue, like you see in the begining of this thread i used wood stick to put my magnet because both magnet have different size so i needed to balance a little bit and find a way to fix it more easyly on the shaft :)

I want to attempt replicating this project, but I'm having trouble understanding this schematic.
(http://overunity.com/newman2/newman1.gif)

I thought there was a hall ic in there somewhere... or something that oscillates???
Where is the contact point that rubs on the axle???
Is this really everything I need to replicate???
Meaning: 12v battery, some 28awg, 10ohm shunt resistor, and a couple neon bulbs?

If not please post a complete diagram listing all components needed and how they are wired.

Hi Dingus,
if you go with the reciprocating setup, where a magnet just slides in and out of the coil,
you have to make this circuit like a door ringer bell.
So connect one contact point to the bottom of the magnet and the other
beneath it.
So if the magnet falls into the coil it makes contact and the coil
repells the magnet out of the coil and the contact is broken, so the magnet
again falls back down making contact again and is repelled again out of the coil.

If you go with the rotating setup, you just need to make
contact once per revolution of the magnet at the right angle.
So you stick the contact to the axis via a commutator.
Pretty simple. No higher mathematics needed ! ;)  ;D

Regards, Stefan.

P.S: Replace the 10 ohm shunt with a incandescent bulb.
The shunt was only there for the scope measurement for
to see the back current spike on the scope.

I should video it at night, the sparks are wild and jump out like lightning. 

I need to secure the bearings tonight and get rid of the duct take, because it torqued the bearings really hard and it has hit the coil a couple times when the magnets gave a little.

Looking good Mike.

Cannot wait this end to get home this weekend and have a play on knocking up one of these!

Regards compressing the video, if you are running Windows XP then just fire up Windows Movie Maker that comes with it. I allows you to mute your Videos and when you save the Movie out it saves it to .WMF which compresses it hell of alot and easier to upload etc etc.

Regards Sean.

With your tools, you should be able to really get this thing going.  The tape idea will need to be replaced by electronics, I did the tape to see if it really worked.  It kills the tape in 30 minutes to an hour (but I marked the gap location).  So I can at least play.

Hi Mike

I was thinking about the tape wearing down with the spark after a while. Wonder if it is possible to paint something on the shaft that will be non conductive and tougher?

I do not know if the effect of getting the spark could be replaced by electronics as it seems to be this that is producing the magic juice!!.

Hope my wire turns up for this weekend, if not I will have to use one of the small 500g roles to begin with and see what resistance it gives me.

All good fun and keep it up mate :)

Cheers

Sean.

Hey guys, been following this thread and am thinking about making one of these, I had a similar Idea about the contacts, maybe use a reed switch? another one would be to use a couple of leaf type switches with a small cam on the shaft. these would at least keep the sparking component.

Just my .02

this is maybe possible to use it, i wanted to use it at the begining but i find out more easy to just put all the wire on the metal shaft :)

but maybe you can get a better result using it, also not sure if the sparks will be as high with a reed switch compared to the shaft

Sounds simple enough! (more simple then any other motor I've ever built....)
Well I bought some components yesterday, and I'll get some more this weekend.
I hope to have something to post by Monday!

Thanks Stefan!

Hi all im planing to build one of these, i have two ring magnets ordered and have been thinking of using a cardboard cylinder that i can obtain for free and cut the end of it instead of using a flower pot, the cylinder will be about 4 inches wide, i will proberbly be getting my copper wire from a car alternator for free hopefully, ill then need my axel with im not sure what type of metal i should use, the size of it will depend on what bearings i can get.

I wasnt aware of this site until i seen the youtube video of that guy with his fan, i havnt build a f@#*ing thing in my life but im determined to build this, im paying close attention to everyone here and have watch the youtube video countless times trying to take it all in as there are no drawn blueprints available.

I basically understand most of what im supossed to do but im not 100% certain about where all the wires get connected, i know one side of the flower pot has the negative from the battery and has one end of the coil brush against the axel where the sticky tape is and the other end of the coil is connected to the positive, so what else more to it is there? i seen on the youtube video on the other side of the flower pot that the positive brushes against the axel is that true it was a little hard to see.

Is anyone gunna put up plans for the wireing with this kind of newman machine?

the wiring is easy, you use the coil, one of the wire go to the negative side of the battery, the other touch the shaft (like a pulse) and the positive side of the batterie is connected to the shaft directly

Thanks the one so where should the magnet be when the wire touches, eg should it be at the part of the revolution when the 2 magnets a vertical or horizontal?

i was doing that but i am not sure if its the best location, but when the magnet are at the opposite of the coil field its prob the bigger push you can get

MRamos

I shrunk your Video and sent it back on email, did you get it okay that end?

If not do you want me to upload from this end?

Good job Mike!!!

Back to the workshop here, things are going well and will catch up on posts later :)
