I am in skeptic mode too,..... but what if it IS real for once?

[Freezer]

@hans
The aluminum bracket for the neo magnets is held on by one screw. Its fastened tightly enough not to swing into the screws, but loose enough for me to be able to rotate it by hand.
As for the hard drive spindle, I don't blame you at all for being skeptical. The spindle was the most convenient thing I had back then, but now I have several bearings I can use. I've been busy lately but I can a better video made soon(ie to give more angles of the device then even fully disassemble it if you want).
@argona
I noticed too that the audio throughout the video was off by a half second, I don't know why this is.

Can you describe the magnets a little more.  Is it just 4 magnets mounted to aluminum, or is it a bunch of tiny magnets? Maybe make a crude drawing showing the polarities. Seems like its tilted which would be a crucial factor.  If this is real, good job and tell us more!  Why didn't you post it here, as this forum above all would be most appreciative of something like this.

@xpenzif,

Could you give some more details for those of us who want to replicate it. First, Jason was curious what the cylinder is made of (its dimensions too). Seems to be plastic but is good to know from you. What exact type of screws are these and what is the exact angle of each row of screws with respect to the axis (the pencil lines seen on the outside surface)? The neo magnets--what are their dimensions and type? Please tell us anything else you'd consider necessary to make it easier for us to replicate it promptly. Thanks in advance.

Hey xpenzif,

What! your not offended by skeptics? 
Thanks. That was unexpected. 

So anyone got a bunch of screws, pvc pipe,
clear dvd blank, neo's, aluminum and old dead vcr laying around?
added:
(or maybe the hard drive with platter is important?)

Hi xpenzif,

I wonder what is the longest rotation time so far you have managed to achieve with your best built setup? Hours? Days?

Thanks

xpenzif,

Wow.. Your response was most unexpected.  Very refreshing.. That in itself adds a bit more believability to your work... I was expecting a bit more defensive posture if you were faking it.. I hope you share your information with the rest of us so we can replicate... This is starting to look worthy of a replication. Hope to see more video soon to help clarify a few things.

xpenzif,
 I did notice that you stated that the screws were a pain as you had to flatten the heads on them. Perhaps an easier way to mass flatten the heads would be to screw a row of 12 screws into a strip of wood then use a belt sander or grinder to flatten several at a time.. If you had a mill then it would even be easier.. If you release a few details I am sure several people here would like to replicate this.

I WILL replicate this in short order, I have all the parts that are needed. I have an O chem test on Thursday that I must study for and a wedding to attend this weekend. But I'm sure I can find the time. The only thing I need to know is the 4 magnets. Are they vertically polarized or laterally polarized. I'm guessing vertically polarized, but I have both on hand.

Good boy xpenzif,

you have come out and you are prepared to talk about what you have done. This is very much to your credit and I applaud you for it. Not only that, but you seem to be also prepared to share your design with others. Whatever the eventual outcome, win, draw or lose you have gained in me a supporter, this kind of attitude is what is needed in the world.

Good luck, I hope it works out for you alright.

Bravo. Finally. A good boy appeared who is turning you into a good man. Hope he succeeds.

The motor in the video was made out of a piece of pvc, the magnets are(I think) Nd45, definitely with poles on the smaller ends.
Screws aren't really necessary, you can build one by cutting washers in half and grinding one side down. Here's a picture of part of a tiny spindle for a desktop toy using the washer design:

This design makes it easy to adjust the angles the washers relative to each other; less change in angle=more torque, more change in angle=more speed, less torque(this can also be accomplished to a degree by changing the magnet arm angle).
The above design uses a lot more magnets. I recommend a shaft made from a non-ferromagnetic bolt.

[Freezer]

Man.. interesting stuff.  I see the spiral taking shape in your designs.  I wanted to know more about your magnet set up.  Can you explain exactly where the north and south poles are? Is each magnet in the same orientation, or does it alternate?  Anyways thanks for sharing.

You are just a prize arsehole!

I think Stefan should delete this.

Thanks for the details. While I'd like to replicate the experiment exactly as you have shown it in the video, I'm curious if you have a video of this last design in motion. Also, what are the exact dimensions of the magnets and the angle at which the rows of screws are slanted with respect to the cylinder generator line? Hope many people can reproduce the device as shown and then go further with the improvements. All the best.

[markdansie]

I like your design,
Just one question, did the washers or screws become magnetised after time and did it change the performance? If this was the case would a set of identical magnets with oppersite poles placed in the sytem help?
Kind Regards
Mark
