Dragged out one of the kids old bikes this end and made a start.

Just waiting for the Metal Weld to dry and will connect the shaft.

Spokes on the bike wheel are not the same so had to cut a slot into the aluminium bar to get it level.

Fantastic!!! (I just read the post above stating this thing has bad reactions from females)  Glad to know your misses has seen crazier ..... (this one really gets to the obsessed on me.....gee.....perhaps it's ME!  Not her? Or plural to that.... haha

kind regards,
Ronnie

Here is my set up....I added a pendulum made of copper to swing past the sticky spot...where can I buy MUMetal??

I know its not a tri gate thread but here is something I dreamed up in 3D

http://www.youtube.com/watch?v=ejpPwI-YGQU

The roller (as others have shown) goes in curved path and also uphill. So it should be possible to return it back using gravity assist (its own weight or with extra weights) and use the momentum (not the weight actually) to break past the entry point.

Counter weight can be used on the other side of the arm to effectively reduce the weight of the roller or you can add more weight on the same side to increase it.

How many degrees the wheel go when you just let it drop from 12 oclock, without the magnets ? (without the pendulum)
And how many degrees the wheel go when you just let it drop from 12 oclock, with the magnets ? (without the pendulum)

And is that an LED ? :)

Hi Omega_0,
  I have actually tried this a while back and I think this is what led me to the conclusion that a setup of tri-gates in a circular fashion as in your 3D model ( which is very good by the way , big thumbs up   ;D ) with a roller mag entering and exiting the array on the same plane is a non-starter unless something can be done with shielding the entrance and exit..   :-\  but again, I would love to be proved wrong. I think the secret to getting a working system with tri-gates would be to get the roller mag to enter/exit the array at as near as 90 degrees as possible so you eliminate the problem of the repulsion/attraction and the ends.

I will be curious to see how the trigate work with it.


Hi AB,
   I have done some tests with a tri-gate setup as in the picture I post in this thread not 100% setup as in the picture but same principle only using 1 pair of arrays. The test i have is a wind down test now to be honest it wasn't done very accurately it was done with a watch with a second hand and a hand spin with and without the tri-gates in place. But it was very promising there was a good 10-20 secs more spinning with the arrays in place and this was consistent until the arrays were slightly out of the sweet spot. The problem with me I really like building side of things and get very impatient when I only have 1 build on the go at any one time, and at this moment I have another 3 builds on the go so I tend to flit between them as and when I can. And now the hold up on the design shown in this tread is the fact that I would like to get more of a oval movement from the pendulum instead of more of a triangular movement. So any suggestions are most welcome  :P..

Hi gwhy!

 I am in the proses of looking for a few good size magnets for the wheel I have built. I have concentrated on gravity wheels so I have not been stocking up on magnets for a larger wheel. But when I get them the wheel will be done and as long as my calculations are correct it should be able to run at least a bicycle generator. But I do hope for better. As for making your oval shape. Let me think ..... Ok I think I got it for you. 2 magnets, one on each side of your tri-gate, this should give a mild tug (due to the overall change of the field) on each side for your oval to possibility work. Don't put them to close but just enough for the tug. You may also have to make one a little higher to keep a single direction on your oval. I played with magnets when I was younger back in 1974 and built a magnet wheel that ran for 1 and 1/2 days before it wore out the center of the cardboard. The funny thing is I didn't think much of it until last year.

Good luck

PS. How I got it to run in 1974 was, each magnet was adjusted individually to make the field do what I wanted it to do, and it was not a uniformed design. Uniform designs make uniform fields and that is the best suggestion I can give for a basic magnet wheel.

a roller mag entering and exiting the array on the same plane is a non-starter

Did you use an inclined plane or was it horizontal ?

If you are sure about repulsion being less if the roller enters from the top (90 deg to the plane of tri gate array), then it can be accomplished. I'll do another animation to show how.
But I guess the advantage will be nullified by the cost of lifting the roller up to that height.
Shields cause problems because they distort the field, so the roller may not move at all. But I never tried so can't say for sure.

Hi Omega_0,
  I had a more or less the exact same setup as in your model on a incline. There is a sweet spot on the entrance/exit of a array no push or pull and I think like you have said :

But I guess the advantage will be nullified by the cost of lifting the roller up to that height.

All the best.

of the subject above... "orbit"....in my humble opinion: oval vs triangel.... oval like a comet in travel (natural)
