Random Blindfold Cubing Discussion

What goes through the head of someone during a 10 second memo? Are you tracing cycles linearly or seeing the whole cube? Are you thinking of letters or going directly from sticker patterns to images? What were the main things that helped you get fast?

So I'm just starting to learn edge comms (DF) for 3 style and I'm trying to decide how I'm most going to execute the M moves (not M' just M)
I've experimented with my thumb, my index and pushing back with my ring finger.
So for instance, M' (U L2 U') M (U L2 U'), how would you guys execute this comm?
(btw I use lefty for pretty much all M moves)

If you use lefty for all your M moves, use right for as many of your U moves as you can (even push U' with your right finger if you can). As for doing M itself, take a page from us Rouxers (who use M all the time). Push up with your ring finger, and use your left hand pulling down the other side of the cube to help. This takes quite a bit of practice to get good at, but it's worth the effort.

I usually memo in 10-12 sec so I think I can answer your question,

What goes through my mind is the letters of my memo, saying then in my head while simultaneously tracing to find the next letter, and simultaneously coming up with images and memorising them as well.

I this this is what most people do whether their memo is 10 sec or 2 min, the only difference is speed.

As for 'sticker patterns', I don't think I do that. When I see a piece on the cube, I do the following:

1) see which coloured piece it is.
2) what letter in my scheme is associated with that piece (for example - G)
3) I instantly go to the place where G is on my cube
4) I see which coloured piece is there on The G spot
5) repeat

The associations of colour to letter to location is automatic now, so takes minimal time, and I don't even think about it.
The only thing I'm thinking about is making a sentence out of my memo (for corners) and making a rough Audio sentence for edges.

As for what helped me get to 10 sec memo, it was mostly Practice, and by practice I don't mean doing solves over and over again, but targeting my weaknesses and improving on them, learning new techniques, and a lot of normal solves to bring all of that together. The main thing is using a good system and being persistent. Do see Noah Arthur's Vids on memo on cubing world, they are a great resource too :)

Thanks for the helpful reply. What you describe sounds no different than what I do already, except it takes me 40-60 seconds rather than 10-12. I'm getting slightly faster with practice, but improvement is slow and I can't imagine ever doing it in a quarter of the time!

i barely ever get a success in 3bld. any success tips?

It's a bit hard to provide tips if you don't explain what you're having trouble with in particular. However, try do a few sighted solves, and when you're comfortable, do a 3BLD attempt with slow and safe memo. This should help with ensuring that your memo is correct, as you should probably focus on success rate at the moment rather than speed. I assume you know what you're doing in terms of execution as you said you 'barely' get successful solves.

ya i know the method well (m2 op) but sighted solves will probably help. ty for helping

Do you go straight from letter pairs to images? I memorise in 20-40s and I always whisper the words of my memo and then, maybe that's dumb and a waste of time :) It also may be the reason why I forget it, because sometimes I just say it and forget to visualise it :D I will try that, that's a good idea to speed up my memo.... :)

yeah pretty much, when i see the colors, my mind automatically figures out the letter pair and the word for that case, which i make into an image :) whispering is fine, i also speak my memo but inside my head :)
 
Guys, i'd really appreciate your feedbacks on my own Rubik's Cube project.
Its purpose is to introduce the Pochmann's M2R2 method to newbies and let them get familiar with notation and solving process (not the memo though).

There is a "tutorial" (which is more like a cheatsheet) with all that's needed to understand how the method works and how to use it.
Being a developer, I've also open sourced the tool to visualize the cube and play with it using standard notation for patterns.

Here are the links:
Rubik Blindfold tutorial
RubikHelper tool
RubikHelper github project (for those of you who have dev background and wants to know more and/or contribute to the project)

Please note that what's stated in the tutorial foresee the resolution actually watching the cube (ie. not blind folded).
It's still a work in progress and I'm aware that there is much more to enhance them... so please, don't be thrifty :p
 
I won a curvy copter cube recently and thought if it can be solved blindfolded just for fun. No problems with deltas (triangle centers) and corners, there are threecycles for them, but the middle edges makes it nearly impossible for the blindsolve. A single 180deg turn swaps two pairs of deltas, swaps two corners and flips an edge, so you have to track a LOT of pieces in case you prefer to flip them manually in the beginning of a solve. One thing I found is you can flip 4 edges on one face to make things easier (like boil down three flipped edges to one):
(M S)x3 // this does x-perm + 4 flipped edges; M = LR, S = FB
(M B M) (S R S) (M F B M) (S R S) (M F M) // this cancels an x-perm
That's it.
I know it's unlikely that someone will give a constructive answer, but still... Can anyone figure out how it can be done? ;)
