<DIV class=txt>Before I devoted my time to this idea, which came to me while imagining a version of the cube that didn't need the intricate connecting tabs found inside a cube, I checked Google for magnetic rubik's cubes, finding none (though a friend found one (theoretically) available in China by removing the 's from rubik the day before I finished this thing). Then I mocked up a 3D version in Maya to figure out the polarities of the magnets to see if it would remain sound as faces were spun all around. It appeared that it would.<BR></DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 2</SPAN><SPAN class=stepTitle>Get some cubes</SPAN></DIV>
<DIV class=txt>I researched cubes of all sorts online, including wooden blocks, "learning cubes," cubes of ABS, PVC, etc, and finally settled on 3/4" clear cast acrylic cubes from Tap Plastics:</DIV>
<DIV class=txt><A href="http://www.tapplastics.com/shop/product.php?pid=136">http://www.tapplastics.com/shop/product.php?pid=136</A>&amp;<BR>I got 3 sets of 10, as I needed 27. The extra 3 helped me test things out, which saved me some big trouble. These aren't all that precise, with romboid and trapezoidal angles aplenty, but in the end, they work well, especially as they're nicely rounded</DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 4</SPAN><SPAN class=stepTitle>Set up the drill press</SPAN></DIV>
<DIV class=txt>I don't have a shop at the moment, so I had to settle on a cheap drill press on the dining room table. I used a needlessly high-precision CNC-milled clamping square from Woodpeckers, makers of fine, high-tolerance machining guides:<BR><BR><A href="http://www.woodpeck.com/groupclampingsquare.html"><FONT color=#0000ff>http://www.woodpeck.com/groupclampingsquare.html</FONT></A><BR><BR>They have a feast of uber precision stuff:<BR><A href="http://www.woodpeck.com/"><FONT color=#0000ff>http://www.woodpeck.com/</FONT></A><BR><BR>I held the clamp guides in place with some small Irwin Quick-Clamps, and later, for some more stability, with standard metal C clamps.<BR><BR>To align things, I eyeballed it: I'd get it about right, clamp it down, then press the non-spinning bit into the acrylic to make a tiny dent, then turned the cube 90&Acirc;° and pressed again. When I got this to make a perfect tiny X in the acrylic, I knew it was pretty good. The cubes aren't accurate enough to be bothered with anything more precise than that.<BR><IMG src="http://www.instructables.com/files/deriv/FIK/VLG3/YRGEP27WQ67/FIKVLG3YRGEP27WQ67.MEDIUM.jpg" border=0></DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 5</SPAN><SPAN class=stepTitle>Get your polarities straight</SPAN></DIV>
<DIV class=txt>It's crucial that all these axially-polarized disc magnets are put in the right way, and I'm glad to say I didn't mess this up once in all 108 magnets. To keep me straight as to which side of each magnet was which, I stuck them all together in one long rod, then drew a Sharpie dot on one end, and peeled that magnet off, and repeated, all the way down. Now they all had a visible polarity, though I don't know still which was N or S.<BR></DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 6</SPAN><SPAN class=stepTitle>Drill out the central piece</SPAN></DIV>
<DIV class=txt>The central piece requires 6 holes, one per side, dead center. At first, I tried using a drill stop clamped onto the bit itself, but this is disasterous. The acrylic going up the flutes gets caught in there, and becomes a heated spinneret of fibers that instantly wraps around the bit, creating a solid acrylic chamfer between the bit and stop that then immediately cuts conically into the plastic. Once I remembered that my drill press had a stop built in, I got perfectly clean holes every time.<BR><BR>I drilled all holes for the project a little shallow first, then tested with a magnet as I slightly drilled more each time, up to the stop value I set in, until the magnet was just a hair's width lower than the surface of the cubes. As the cubes aren't all exact, I couldn't just rely on the stop itself.<BR><BR>The trick is to not let the magnets touch. In that last hair's width, their force becomes tremendous, and it's much harder to shear them apart. Better to let them be lower than the surface, and have only the acrylic surfaces slide against each other.<BR><BR>The magnets themselves slid in to an almost air-tight seal. Their slippery nickel-plating helped a lot here. To get the magnet back out after I tested it, I simply pushed the block up against part of the drill press, and it fly out and stick to the metal. In this way, I could keep drilling just a bit more and dropping the magnet back in to test for the right depth. Many times, however, the holes were the perfect depth after the first drilling.<BR></DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 7</SPAN><SPAN class=stepTitle>Glue in the magnets</SPAN></DIV>
<DIV class=txt>Without prior testing, I settled on Duco Cement from my local hardware store. You can see in the first two images that I'd put a bit of the glue in the hole, then push the rod of magnets into it, and slide the rod sideways to leave the tip magnet in the hole - always remembering to check the polarity.<BR><BR>In the third image, you'll see an interesting phenomenon of my materials choices. Duco Cement eats through faults in acrylic. As such, the circle at the end of the bored shaft, where it meets the crown, would "bloom" outward at a roughly 45 degree angle cone. Quite pretty, though not what I intended. Some of these blooms got pretty complex and wavy, but most just appeared like the conical cloud of vapor that trails supersonic jets. As the glue rehardened each time, the structural integrity of the cubes was not compromised. If I make another cube, I'm going to test other glues to find a nice clear one that doesn't do this, but still has this kind of strength and fast-drying time (30 seconds or so). It remains an interesting thing to see, however.<BR><BR>Be sure the 6 magnets you glue into the central piece have matching outward-facing polarities.<BR></DIV>

<DIV><SPAN class=stepLabel style="PADDING-RIGHT: 5px">step 9</SPAN><SPAN class=stepTitle>Drill and fill the 12 edge pieces</SPAN></DIV>
<DIV class=txt>Now it starts to get fun. The edge pieces each join a pair of center face pieces, and eventually a pair of corners. This leaves 2 faces undrilled, and you just need to make sure these 2 faces connect along one edge.<BR><BR>Again, make sure your polarities work. The two sides that connect to edge pieces need to match - so both N or both S facing out, because a piece can get spun around and return flipped to the same position. Likewise, the corner-facing sides need to match outward-facing polarities, for the same reason. In my model, the edge piece facing sides are opposite in polarity to the corner piece facing sides. This is probably the best way, as I've found that my cube can combine very well in all manner of unexpected positions.<BR><BR>You'll note in the pics that you can now make a central 3x3 layer with 1 central piece, 4 center face pieces, and 4 edge pieces.

<DIV class=txt>My newly-acquired cubing habit has not only spawned a bunch of weird project ideas like this, but has also seen me gather lots of official cube junk to me, and as such, I have a stack of nice PVC labels (the polypropylene are crap - steer clear of these immediately-peeling nightmares).<BR><BR>Many people, including me, prefer the beauty of the clear cube, but as this one is my first, and kind of homebrew looking, and because it got boring having nothing to solve, I applied some official labels and made it a real cube, albeit satisfyingly heavier. You really feel you could do some damage throwing this little cannon ball.<BR><BR>The only thing to note here, besides making sure you center them carefully, is that if you want it to be official, you need to put orange opposite red, green across from blue, and yellow on the flip side of white. Also, you need to get the winding order correct. For example, if white faces up (and thus yellow down), and blue faces you (and thus green away), then red needs to be the left face, and orange the right.<BR><BR>Enjoy your new cube, labeled or not, and remember that if you want to apply imagery to the faces of the cube, the edges and corners will always work out again when you solve it, but the centers can end up in 1 of 4 rotations, which greatly increases the number of possible solutions, and makes solving it by traditional methods all kinds of way harder. You can use that to your advantage in a cube with a pattern that can have its subcomponents twist without getting messed up.<BR><BR>Luckily, the magnetocube is easy to take apart and put back together, either way <BR></DIV>

最关键的，贴磁铁时极性一定要弄好，否则就不是相吸，而是相斥了。呵呵

我靠，太酷了吧，收藏绝对没话讲，不过转起来会不会很容易散架啊……

我不找，找到了又想去做，最近有一段时间没练习魔方了，不上你的当。

cong从哪里搞到的图 太漂亮了 啥时候我才能拥有一个呢
作者: kexin_xiao    时间: 2008-5-13 19:41:52

收藏是极品，但估计转可能不适合，呵呵
作者: veronica64    时间: 2008-5-13 19:54:36

有谁能提供这种材质的购买地址么

</P>
<P>&nbsp;</P>
<P>我同意老大的看法，普通的玻璃由于成型的时候存在内应力，有一些加工方法，我认为是很难精确完成的。</P>
<P>&nbsp;</P>
<P>文中所说，试过了木质，PVC塑料，ABS塑料，最终选定了聚丙烯塑料，也就是用来作微波饭盒的塑料的同样成分的另一种聚合物。</P>
<P>&nbsp;</P>
<P>我觉得如果是有机玻璃或者其他透明的塑料，比如PMMA（有机玻璃），PS（聚苯乙烯）等等，设计加工方便，原料也好搞。比较可行。</P>
<P>&nbsp;</P>
<P>至于磁铁，文中提到了结构设计，结构上是可行的。磁铁用的是买到的磁头用的磁铁，文中说，钕和稀土元素的磁体，我的经验大约是硼钕稀土永磁材料。品牌大约是K&amp;J</P>

坦率的讲，楼主，其实这魔方的材料不是普通意义上的玻璃。

很久以前农民好像是发过这个帖子，不过只给出了链接，非常想拥有一个，其他问题都解决了，就是这种水晶弄不到，价格不菲……不知道哪位魔友可以弄得到

我想买啊...如果哪位大大有成品的话...希望割爱啊
作者: 大头    时间: 2008-5-16 00:28:31

回43，文中提到的大约是成品的方块，每套10个买了3套，国内我不知道有没有这样的成品。可以买大块的PMMA有机玻璃进行切割打磨。

<P>谢谢你的提醒~那这样说就改成“PP魔方”好了，或者说“聚丙烯魔方”，“塑料魔方”？</P>
<P>&nbsp;</P>
作者: 大头    时间: 2008-5-16 12:26:21

其实无所谓的，玻璃质感的~~，并且文中所用的这种材质的确很不常见。也不用改成“塑料”什么的呵呵。这样挺好的~
