Ultimate Ball Tutorial (Icosahedron, Zen Magnets)

[@evenman27]

Thank you, Boyd. Every time I upgrade my collection I come back to your channel and build the next crazy contraption!

[@vincentvanbeelen837]

A very clear tutorial with good instructions and tips! Thank you!

[@livrichardson6372]

Thanks Boyd I've been trying to make one like this... Ever time it breaks but this was amazing. A true master.

[@YoyoBandalore]

After all these years, I finally got around to making this figure. HA! Thanks for the tutorial.

[@boydedwards5475]

That's very generous of you, Peter. Thanks!

[@darkenedlight4818]

Zen Magnets are finally for sale again, I can't wait to get some. I ordered the set of 1728 and an additional set of 216 to start with just so I would have enough to make this shape. It's an awesome shape! I can't wait to finally be able to build things. I've probably watched this video 10 times.

[@boydedwards5475]

This shape is one that I flagged as super interesting when I first became interested in magnets. And I, like you, wanted to make sure that the total number of magnets I bought exceeded 1860 so I could build this shape. It's such a neat shape!

[@magventure1019]

How Much Was The 1728?

[@SamChaneyProductions]

Going to build this right when I get home. Already started it with my work desk set.

[@boydedwards5475]

Great! Loved your Flagship video.

[@TheDrgnfyre]

Thanks, Boyd. Can't wait to try this out. I had seen this shape but was getting frustrated before trying to build it.

[@aesir-d5j]

This was a little hard for me but just looking at it was the coolest thing ever!

[@itry-gu3nc]

Great tutorial really don’t want to take it apart now but it’s used up damn near every magnet I have.

[@tomnerko]

Nice Tutorial. Much clearer than the other one. Which wouldn't be so bad if they guy spoke instead of just spinning his finger in a circle. Both work, but this one is much easier to follow.

[@GymTrainingPro]

you are THE zen magnet master!!

[@Balgore8]

I am actually going to make this right now lol. Can't wait!

[@oinoi8373]

Finally today I have enough magnets to make this!!!

[@Balgore8]

sick man great tutorial!

[@-N-A-]

I spent hours trying to create this but I kept messing up since I use 3 mm balls. I finally was able to build it using a different method that I created that is much simpler. Basically just make a pentagon shape with 15 rings (5 rings in the center and 10 around it) and then make 12 of these and connect them all together. Just make sure that when you connect them you don’t attach each pentagon exactly side by side-it has to be off kilter by a little each

[@boydedwards5475]

Thanks. I'm glad that the tutorial is helpful!

[@boydedwards5475]

Heidi, you can get them at the Zen Magnets website.

[@boydedwards5475]

Thanks and good luck with the build, Balgore8!

[@michaelspencer8024]

Thank you good video

[@GalaxyTraveler]

Excellent job again, way easier than the way I did it some day :D

[@olegyefremov2583]

That's seems very hard. Thank you for awesome video. I'm barley making squares lol. Another shape I thought was cool and I manage to do it is triangle

[@kristihulit3509]

Waiting for a new tutorial. I have 9072 magnets now.🙂

[@SamChaneyProductions]

So this is basically a stellated dodecahedron, sort of like if I made little cones of base 5 and built a dodeca out of them, but instead replaced each ball with a unit of the 2 hex rings. The holes are in the same place they would be with the single magnet version. My large magnet shape paradigm is expanded so thank you!

[@boydedwards5475]

I think of it as an icosahedron, because the pentagons go just where the vertices of the icosahedron go. But you can also think of it as a dodecahedron, given that the icosahedron and the dodecahedron are duals of each other.

[@SamChaneyProductions]

Boyd Edwards yeah I thought of it that way too but it's easier for me to conceptualize it as the dual because I only have to mentally keep track of 12 units. Thanks! Just made it tonight!

[@boydedwards5475]

Congratulations! It's a really beautiful shape.

[@joejoseph3078]

I cant wait to get more magnets to make more sculptures!

[@boydedwards5475]

Better hurry. The government is doing its best to shut down magnet sales. A sales ban will be in place beginning on April 1.

[@Ali-sh4ib]

Boyd Edwards are you serious? All magnets even from radioshack? If so i better get as much as i can so i can finish all my projects i plan of..

[@boydedwards5475]

Ali Hegazi I don't know about Radio Shack. But all of the magnet sphere companies have stopped sales in the US except Zen Magnets, and if the judge rules in favor of the CPSC, Zen Magnets will have to stop sales on April 1. You can get them from industrial sources like K & J Magnetics, but they are more expensive there.

[@josephkim2719]

This structure actually uses more than 1860 balls.. so for all of you guys buying 9 sets of 216 balls..... you actually need 2220 balls for this structure: This structure has 12 sides each side is composed of 15 sets of 12 balls (6 balls on top of each other) linked together to form the double layer so one side is equal to 15 * 12 = 180 balls Now because you have 12 sides, we multiply 180 * 12 = 2160 balls so far by now you'll have all 12 sides connected and all that should be left are the holes on the vertices of each side we need 5 balls per gap and since there is 12 sides so 5 * 12 = 60 so in order to make this structure you need 2160 + 60 = 2220 balls NOT 1860 balls idk how this guy managed to make it with 1860..... does anyone else follow my logic here... it can't be just me

[@kateychoi9051]

Joseph Kim i hear ya buddy

[@boydedwards5475]

Joseph, great job in breaking the shape down into 12 pentagonal faces, each with 15 sets of double-stacked hexagons (with 12 magnets each) and each with one 5-magnet pentagon, for a total of 2220 magnets. This approach overcounts the number of magnets needed because the 5 corners of these 12 pentagonal faces (each corner being a double-stacked hexagon with 12 magnets) are shared with neighboring faces. To get the correct magnet count, you can start with the 2220 magnet count and subtract 360 magnets (given by 12 faces times 5 corners per face times 12 magnets per corner, all divided by 2 because these corners are double counted in the 2220-magnet total), for a revised total of 1860 magnets. Dozens, perhaps hundreds of people have built this shape with 1860 magnets, as I have. That's all you need to build it! If you need further proof, see my video, in which I build it with 10 stacks of 30 hexagon rings and one stack of 12 pentagon rings (with all of these magnets shown in the video at all times - no hocus pocus!), which also amounts to 1860 magnets. Cheers, Boyd

[@ishum7060]

I only have a mandala set. A 1020 version existed but does not anymore. Can someone give me a tutorial

[@brighambrewer5761]

Vortices eh? This is a model for our hollow earth, don't you think?

[@boydedwards5475]

+Brigham Brewer Something like that.

[@mochipeachee]

Where can you get these ball magnets

[@darkenedlight4818]

They were banned in the US for safety concerns for several years but are finally for sale again as of Nov 2016. They're being offered for preorder on the Zen Magnets website.

[@boydedwards5475]

Ali Hegazi: this shape can be built in only one size, with 1860 magnets.

[@ResidentNotEvil5]

Wow that was nice I ordered 2sets of neo cube 512 balls

[@magventure1019]

Can It Not Be Built Any Smaller?

[@rextson9189]

Can I build this with 1300 magnets?

[@boydedwards5475]

No.

[@rextson9189]

@@boydedwards5475 Is there something else like this i can make?

[@yantingchen8109]

Where do you buy them

[@boydedwards5475]

You can buy them at zenmagnets.com.

[@longliveangelo8938]

Would I be able to get these on amazon?

[@boydedwards5475]

You can get them on zenmagnets.com

[@brunoassad1512]

Can I do it with 216?

[@boydedwards5475]

No. You can build other spheres with 216 magnets, though, such as the 60-magnet rhombicosidodecahedron, sometimes mistakenly called the C60 molecule.

[@any20060]

from where do you buy zen magnets

[@boydedwards5475]

+onaisa hayat hayat They are no longer available in the United States. You can buy them from K&J Magnetics for an exorbitant price. There are some places overseas like alibaba.com that sell them, I think. Just search on "magnet spheres" and see what you find.

[@idk-nm8xr]

+Boyd Edwards why would you asume he is in the us?

[@boydedwards5475]

+Shotin FPSuser I made no assumption that he or anyone else is in the US. I simply communicated all that I know about the availability of Zen Magnets. I know only about the availability of Zen Magnets in the US.

[@chadcastro2310]

maybe at vat 19

[@idk-nm8xr]

maybe im dumb :/

[@ttvgrey2790]

Why the heck would we have that much magnets laying around

[@alexnelson8]

Darn, I’m 130 magnets short...

[@itsmehava8814]

Omg this video is older then me

[@biancamccormick3989]

If you go on focal price it's cheaper then spending 50 dollars you can get 216 balls for 5.00

[@sean_haz]

They are 3mm whereas zen magnets are 5mm, they would be $13 not 5

[@promangr5632]

πολύ δύσκολο

[@boydedwards5475]

I wouldn't say it's "very hard." Just takes a bit of patience.

It's all good if you have about £600 knocking about to spend on the magnets.

Can I buy a zen PVC card off you ;)

[@boydedwards5475]

Sure, or you can probably get several for free, or thereabouts, from zenmagnets.com

[@isaacguyman8456]

I checked zenmagnets. They don't sell em by themself, cause I bought 216 zen magnets for 10 bucks off a legit site. can i get one ._.

[@physicsdemos]

Sure. I'll give you one. Perhaps you could send me your mailing address to my e-mail: [e-mail].
