This is the third version of the button cube (and the 4th button cube) that I have made. Apologies to purists: I finally resigned myself to the fact I wasn't going to be satisfied with quality unless it was 3D printed (Many thanks to Bradley for his excellent service).

This version moves very smoothly. Buttons stick a little, but I think it will ease up with more lube. The buttons use a hooked rail and the cube has a spherical geometry internally rather than cylindrical. This means it is extremely stable and almost impossible to pop anything.

I made some pieces for another puzzle in un-coloured resin, and liked the ivory effect, hence my first (off-) white puzzle. I think I like it better than the original!

Wow. Great puzzle!

It looks like the first challenge in solving that thing is to scramble it! :lol: Have you tried solving yet?

A video would be much appreciated!

Looks amazing!
It is obvious that you put 100% into this puzzle..

Just this weekend I was wondering, when we would read any news about the Button Cube.
Is that your final version now or do you expect further improvements?

Cheers - Frank

Question: Do the buttons themselves turn?

The button cube is a very interesting idea, and it looks well done. Nice job!

I'm really wondering about a solution for this cube. The first question I have is how scramblable is it? It seems that there would be few paths one could take and so it would have significantly less positions than a normal cube. Would it be possible to just undo the steps or at least get close? Assuming it can be scrambled fairly (randomly) I would then suggest the following solution:

1. Solve 3x3 pieces in any way possible. I'd have to have the cube in my hands to say anything more about this step, but I believe I could eventually come up with a method that works every time.

2. Solve the buttons. This is done with 4 move commutators and is relatively simple. However, I'm not quite sure of the button positions and so set-up moves may be required, but the idea would be the same. Could I have one more picture of the cube in solved state in a different orientation from the first two pictures? This would help me figure it out a bit better. A video wouldn't hurt either :wink:

I already had it in my hands and played with it for a while. Tim sent it to me to present it for him at the DCD2008.

It is definitely a bigger task to scramble the puzzle to a non-trivial state. The buttons are an obstacle all the time, because they are distributed regularly on the sides of the puzzle, so all axes and cuts are affected. If you finally have mixed it up, step 1 is already quite difficult, because you have to exchange the pieces of the buttons frequently. The reason is, that they consist of halves and quarters and for some turn sequences you need a button consisting of quarters completely. Sometimes I felt there weren't enough quarter pieces for me...but that's always the crucical part with bandaging. It is always locked where you don't need it. And I am not very good in solving bandaged puzzles, I have to admit. :oops:

Solving the buttons is indeed not so difficult afterwards.

I didn't solve the puzzle completely before I finally sent it home, but I am confident, that I could solve it - and I'm looking forward to a second chance :)

This puzzle looks so interesting and exotic.
GREAT progress! :) wow
Is this the final version or will you upgrade it even more?

I asked him the same question personally. Yes, this version is final.

Frank has it. The only changes will be minor: Cubesmith stickers. Different colours if it is demanded. I have a good variety of pigments, but anything other than black/ white or ivory is a bit more costly.

This is the final version, I don't think I could get it any better.

Sorry about the lack of video, I simply have not had the time to get it sorted. It will come!

Thanks for the kind comments from many people. Much appreciated, it has taken 6 months (among other projects) to get this one this stage, and uncountable hours of thought and work.

Cheers

Tim

PS (Edit)

When it comes to solving, at the moment Frank is the expert. He has got it far further than me! My feeling is get the buttons whole first regardless of colour otherwise nothing moves anywhere and no sequenced moves are possble.

I thought for sure I commented on this, but it looks amazing!
