Roll on the 20th June

Hey Ex... thanks for the vid.

One thing to remember when trying to intersect arrays as in my video is that  the exit point of the arrays is 3/4" away from the plexi - LOWER than the entry point of the second array. Therefore the plexi is pushing the roller mag away from the field towards the end of the arrays. Notice the blocks of wood - their spacing & location.

Unlike AQ, I think this is critical - more important than simply ramming one array into the side of the other. I think the key to some of this is moving the mags outside of one simple plane - I.E. using a third dimension in your build to "regulate" the strength of different parts of the array - the point of my second vid.

'Xactly! (Exactly)

Magnetic fields are not 2 dimensional, but 3D. I've always been a big proponent of the "ramp" (Q-tip theory, etc.), but it was gwhy! that 1st used the 3D concept in his "K gate" (which uses 2 - 90 degree bends in a MkE array to marry it to a trigate array and make demonstrations of "breaking the wall".

I'll look @ your vid again to see exactly how the slope aligns w/ the arrays.
I DID notice on how "going backwards" [starting from the left hand side] in your array build seemed to have much more velocity than when the roller was rolling down the slope [right hand side] to be sucked into the array entrance.
It also seemed to encounter much less "turbulence" (twisting/spinning for alignment with the array) at the array intersection and keep much more momentum as a result (probably a result of the incline + array attraction).

Now that I have looked @ the vid again, I see that the the 1st array (going right to left) has a grade of 15-20 degrees starting high on the right side, but the 2nd array seems to be level (or sloping down left to right).

Hmmmmm....it's making me wonder what other slopes or shapes might be beneficial.

The latest idea (not realized yet, just bubbling around in the cortex) for array building is to take a slice of "pool noodle" material and build the array IN it.
By drilling holes in it with an altered drinking straw [I showed this method in one of the gravity toy vids I did much earlier], populating the noodle holes with mags [maybe with drinking straw "sleeves" to give the outer circumference of the hole greater area to support the attract/repel effects of the mags] to form a MkE array (or any other type for that matter), and then wrapping it with plastic packing tape or medical cloth tape so the result is a flexible array that can, with enough support, be formed any way an experimenter would wish (within reason).

I thought it MIGHT be nice to be able to form different shapes, or alter those shapes slightly, without having to machine "hard" supports for the arrays each time.

Just some thoughts. I'll get up off my dead butt here "soon" to try out the idea.

Keep playing kids!

@those trying to arrange neos for the Mayernick array

I see lots of you trying double sided tape for your arrangements but my wife had an idea (untested by me but looks promising).  Has anyone heard of oasis ? it is a green block of foam used in flower arranging

example link:

You would just press your mags into the foam in any arrangement you want.  Not sure if it would be strong enough for the big mags, but for the small ones, it might be a relatively cheap solution.  You should be able to get it at any flower store.

Just a thought.

I haven't tried to close any loops because have a very limited number of neos right now. If you look back you'll see that everything I've done so far has been done with 30 - 1/2" noes. Very limiting.

I need to order more noes to move forward with some of this stuff, but I have other projects that are taking up all my time/money right now.

I can't find any info on the "Finrod mobila thing". Could you elaborate or link? thanks!

i included the link @ the bottom of my post .. it reminds of your setup because of how the rings in the Finrod device tilt as the ball moves around the rings ..

Heres the link again ..

i know this is off topic but i wanted to share something i found today .. it's for the new apple iphone 3g..

Got this new phone on my birthday not too far back ..
i really love it ! !
really freaking amazing communication device !

Captain Kirk's communicator pales in comparison  ..

Streaming live video to the net ! !
in a few moments a tour of one of data centers in Montreal Quebec.

Heres the url my live video stream coming via the iphones camera ..

@ Que, very cool ! , but I would get into way too much trouble with that.
