Maybe the magnets I've bought are a little weak then. We'll see.I considered fitting magnets in 3x3x3 cubes back in the 80's, inspired by the ball-bearing click action of the pyraminx.
I never pursued it, it was just the idle thoughts of an engineer. I was obviously contemplating using ferrite magnets. The rare-earth ones were expensive and hard to obtain, the only ones I had seen at the time were in the earpieces of headphones. I was thinking of fitting them in just the edge pieces, and having steel plates in all 4 sides of the centre-pieces. I didn't want to fit them in the corners, as back then corner-pieces were sealed up, the final face was superglued on.
It's interesting to see what's been done with the current magnetic cubes. If you haven't already seen it, here's one 'homebrew' attempt:
That was exactly my plan but I now suspect that the N35 magnets might be too weak. I've ordered N52 magnets instead. They could be too strong but I'm going for it.I'm seriously considering making a magnetic stickerless Valk 3 using 4x2 N35 magnets. Has anyone had any success with the Valk, and any thoughts on magnet choice, or other tips??

I think placement is more important than people think. If they go close to the outside of the cube then they will be more accurate but if they are closer to the core they will kick in sooner. Finding the right balance is, I assume, a big part of the Cubicle's research costs.Depending on your skills and tools (I'm thinking 'Dremel' type tools here), you could probably fit the magnets closer together, by making a recess for the magnets to sit in. They may not pull so well when the faces are misaligned, that's the problem. There's likely to be some optimum spacing/magnet-strength, where the magnets help align, without being overly-strong when they are aligned.
Agreed. Also, drilling 48 identical holes with a dremel would be a nightmare. I think it's all about the placement and strength.I think placement is more important than people think.

Yes, I've seen them. I keep changing my mind about the strength and I'm now considering practicing on a Thunderclap first.Agreed. Also, drilling 48 identical holes with a dremel would be a nightmare. I think it's all about the placement and strength.
Have you (I assume the answer is yes) watched DMCubing's YouTube tutorial for making a magnetic Valk 3? He is of the same opinion to you re: N35s. Might go for something in between.
Have you given much thought to epoxy selection?

By this do you mean repel into place? Kind of like maybe if it gets past a certain point, it will repel away into cube position? Equalizing with the other magnets? That could be cool, but may make turning it a bit harder ahaAnyone tried adding magnets to a cube but making them repel instead? Probably a bad cube but it would feel cool.
Just a quick question, what would you think about a Magnetized Senhuan Mars? The cube is mediocre as a whole, but mostly because of stabiliity, I feel like the mechanism would benefit from it. Opinions?Yes I asked Chris Tran, and he said he had tried it but the force needed to turn through the repulsion made it feel weird.
