How to Solve a Rubik's Cube Blindfolded

How do you tell the difference between the 3 sets of corner orientations, e.g., UFL, FLU, and LUF?
 
Thanks Raoul, I will definatly look into Badmephisto's video. I did not know he had one. He is the best cube tutor in the world ;)

Just bear in mind that the memo method badmephisto teaches is pretty bad. You'd be much better off with Noah's tutorial for memo at least.
 
One Question, what is the difference with UR and RU???

The letter that comes first is the face that it is on. RU would be the sticker on the right face of that edge piece and UR would be the same edge piece but with the sticker on the U face.

As a warning, you probably should have asked that question in the one answer blind question thread (http://www.speedsolving.com/forum/showthread.php?27353-One-answer-BLD-question-thread-blind). Stefan will eat you otherwise.

Depending on what method you are using, it means that you are cycling your piece to the same spot, but with a flipped orientation.

Hold your cube with yellow on top and orange on front. UF is yellow-orange, since the U corresponds to yellow and the F corresponds to orange. Since you have a fixed orientation when BLD solving, this shouldn't be too difficult.

Edit: ninja'd
 
Thread has been dormant for a bit so sorry for bumping. How do you know when you are done with memo? I am currently working on edges (will work on corners later) how do you know when you have memoed all the edges? do you just have to keep track if you have done each one? also how do you keep track of cycles? Do you have to remember where the piece that goes in the buffer is in memo? Thanks!

You don't need to remember where the cycles end, you just need to make sure to letter them correctly. As for knowing when you're finished, at first it can be quite difficult, but eventually (at least for me) I started figuring out if I had anything left by deduction. For example, I know if I had 10 targets with no cycle break before hitting my buffer, then I had once piece left. If I hit my buffer and it's oriented correctly (I finish on the DF sticker rather than the FD for M2), then the last edge is already finished, and if I hit the sticker oriented incorrectly (FD instead of DF), then I know the last edge needs to be flipped. If I have0 cycle breaks, I should have 11 targets, 1 cycle break, then I should have 12 targets, 2 cycle breaks, I should have 13 targets, etc. I don't really consciously thing that way now, I just get the feeling that something isn't right with my edges and I need to check for a solved or flipped edge.

I don't quite get what you are saying. What I am asking is how do you know if you have a new cycle break (after the first) with out remembering where your buffer piece is? Is it possible? do I just need to remember?

Thanks for the advice on knowing if you are done with memo. That makes sense!

If you have a second cycle break then whenever you reach the buffer the second time the solve should be done. Also, if your buffer ever comes back flipped then you have another flipped piece too that you need to fix. Like DeeDubb said, after a while you begin to just instinctly know if you are done with your memo and stuff.

It's awesome that you're working on BLD, I wish that it was an event in the comp next month. If I do end up organizing a comp I will definitely have it.

So how do I know if I have reached my buffer again? do I have to remember where the buffer piece is? What if there are more than two cycles?
What I do is have a standard order of new cycles to break into. I memo until I reach the buffer the first time. Then I just T perm to break into the cycle that starts at UL, if UL or LU has not already been memoed. Then memo again until you get back to UL or LU. If you get there without having memoed all edges, you need to start another, so you repeat with a different piece. My order is UL, UB, UF, DL, BL, then FL, for no particular reason. I realize that this is more cycles than you would run into in a solve, but if you solve UL UB and UF in the first cycle, you might need the rest

Thanks! That makes sense. I usually just T-perm if possible to. I'll play around with that.
