Expanded Perfect Sphere | Tutorial | 3780 Neodymium Magnetic Balls

This is super impressive! My experience with the classical 'ultimate ball' would have led me to think these would be incredibly fragile; I guess the opposite-polarity connections are just that strong!

[@ledwatchman]

Thanks Magnenaut, yes the double layer alternating polarity pattern turns out to be very strong. It also easily supports my supersized version of 7080 magnets: kzbin.info/www/bejne/rZqmlGONgaeVsNk

Oh my gosh that is so awesome to watch. You are so skilled at that.

[@ledwatchman]

Thanks Karen. A lot of the construction footage was sped up 3x, in case you thought I could really build it that fast, lol.

[@karenwood7623]

Lol, at first I thought you could but then I realized. You might get to be that fast someday. :)

Hi! For the 4 magnets to fill each gap, I'm having a bit of trouble with it. Is it supposed to match with the bottom layer or the top layer (of double 6 rings)?

[@ledwatchman]

Hi there, sorry for the delayed reply, have been without internet access for a few days. If I remember the line of 4 balls to fill the gaps tend to connect to the bottom layer around the outside. One polarity will work well, the other won't as I stated in the video, so try fitting the 4 balls in each gap from the other end of the line of 4. Thanks for your interest and I hope you can complete the sphere successfully, and that this comment is of help!

Can you make a tutorial for the small sphere I just can’t seem to figure it out

[@ledwatchman]

Hi, sorry I can't do a tutorial in a hurry, but I can try to describe how to build it. All double rings required are of the same polarity. Make 12 rings of 5 double rings of 6, and bond an entire ring to another entire ring one pointy end first, not side to side. If you start with 3 rings of 5 (double rings of 6), they bond in 3 places and you should start to see the pattern form of triangles of 6 double rings leaving a gap to be filled in between by one extra double ring of 6. There are 20 of these gaps formed in the whole sphere, so the total number of double rings is 12 x 5 + 20 = 80. You can also put rings of just 5 magnets inside each ring of 5 double rings of 6, to fill in the vertex holes and make the little sphere look completed. A total magnet count of 80 x 12 + 5 x 12 = 1020. About halfway through my video I show how to build a ring of 5 double rings of 6 and put a ring of 5 magnets in the middle of it. I hope this helps.

Hi, I've just uploaded a new multi tutorial video which includes a guide to this small sphere at 2:07 : kzbin.info/www/bejne/jn2YmoeEg5Wqe9k

Thanks

[@ledwatchman]

You're welcome, so you got the sphere built ok then?

[@Urmomgay-pt6ul]

Kinda

[@kank_a4609]

seeing diferent colours in each magnet lol im driving crazy?😂

[@ledwatchman]

I used a mixture of faded well used gold, and standard nickel (silver) magnetic balls in that video, to indicate different polarities in the structure, but because of the worn nature of the gold they ended up looking harder to distinguish from one another than I intended 😝

@@ledwatchman oh lol i thought i was completely mad 😂 thx for the answer and also +1 sub
