Blindsolving Accomplishment Thread

1:23.xx 3x3x3. PB. First sub-25, third or fourth sub-30 I think. No parity, a pair of flipped edges, edge memo was one very long pronouncable word, so it was VERY fast memo (I just "extended" the pronunciation as I went along, sweet) :D
 
yay i just did my first successful blindfold solve two days ago. i had been blindfold cubing a 2x2 pretty well, so i decided to learn the edges (which i already sorta new) and have a go. i did it on i think it was my third attempt :). i need to work on accuracy for now.
 
I just did my first 3x3 blindfold solve this morning! It is so cool to open your eyes to find out if the result was total chaos or perfection.

I spent time late last night trying to memorize it, noticed I was forgetting, so I finished memorizing in the morning. I wanted to be able to "recite" the data for each stage. I think I took maybe 1 hour memo total, and maybe 20 minutes to solve. (I had no concern about timers or clocks.)

The scramble was from the "Doug JTimer" version of JNetCube,
D R B' L' F D2 U L2 R' D' U2 L2 B2 L' D F2 L' B D2 R' B2 F2 D R' L2
with F=white and U=green. (That's default for JNetCube, but not WCA regulations.
Edit: I emailed Doug. He has fixed this for his June 1, 2008 version.)
When I solve cubes, I have F=orange, U=yellow. My cube opposites are colored r/o, w/y, b/g and the r,w,b corner goes clockwise.

I used the 3 cycle method as described by Macky. I number corners as 1=ULB, 2=URB, 5=DLB, etc. I number edges as 1=UB, 2=UR, 5=BL, 9=BD.

This is my memo, as I recall now...
Corner orientation: BAAC ABAB (where A=anticw, B=okay, C=cw)
Edge orientation: 5A6 (hexadecimal for 0101 1010 0110, where 1 means flip)
Corner cycles: (1),(2),(3),(4,8,5,7),(6)
Edge cycles: (1,3,7,11,10,12,6),(2,4,9,8),(5)
Yeah, the corner cycles aren't too bad, but the parity makes it tough.
Edit: just double checked after my post to see if I recalled my memo correctly. Yes, I did!

At the end I had to swap corners (4,7) and edges (2,8). I couldn't think of an easy way to set them up for an easy PLL. Then I realized I could swap edges (2,8),(1,3) and then setup for a T permutation, do it, and unsetup.

I couldn't believe it when I opened my eyes!

Congrats man! I'm feeling very happy for you for some reason, maybe it's because of your age (no offense there :p), maybe it's because it took you so long and so much determination to get it done, maybe it's because my first solve had parity too :p I dunno, but for some reason, I'm feeling for you :) You can now proudly tell everyone that you can solve a cube blindfolded :D

P/S: Hexadecimal edge orientation is COOL :D (however impractical it may be :p)

Thanks! No offense taken. The fact I am 53 years old is a big reason why I feel so proud. This was pretty much my 3rd attempt with a full 3x3 scramble. On my 1st attempt, a couple days before, the result was all the corners oriented and positioned right, except for a D' twist. I think I missed 2 edge flips, and edge positions were messed up mostly due to that D' twist. I was close! I think my 2nd attempt resulted in so much chaos, I laughed out loud. I had no clue what I did wrong, but I assume I forgot to undo a cube rotation at some point. I practiced stages separately again. Last night, I gritted my teeth and was determined to accomplish it. I went carefully. My biggest concern was memo.

I like Hexadecimal for edge orientation. It gives me just 3 "digits" to remember rather than 12 bits. I would definitely consider alternatives!

My next goal is to be able to do BLD in under 10 minutes. (7 for memo, 3 for execution.) Then I want to return back to regular speedsolving, and learn all my OLLs and work on finger tricks, with a goal of dropping my 47 sec avg to maybe 25 sec avg.

7:53.94 4x4 BLD... :) Visual memorization is the best.
 
Did my 2nd successful 3x3 BLD ever. No parity, 8 edges needed flipping, 3 corners ccw, two 3 cycles for corners (2 in place), a 7 cycle and 5 cycle for edges. I have no clue on the time. I guess I should start looking at a clock next time. (I thought 20 minutes for both memo and execution, but I might be wrong.)

This was just a few minutes after I failed an attempt had left only a UR and DL edge flipped, all else correct. Parity with 6 edges to flip, 2 corners cw, 2 corners ccw, one 4 cycle for corners, 4 corners in place, 12 cycle on edges. (How often would that happen? 12 cycle on edges?) The fact that I was so close made me try again.
 
first 2x2+3x3 sleep (more like 24 hours) delay solve for me. Memo last night didn't solve until about 45 minutes ago. I had to recollect for about 30 minutes and a 15 min execution was ok for me knowing it was a sleep delay solve. I will try this again tonight and see if I dont forget during classes.
 
3x3x3 BLD: 40.55
Scramble: F2 L F L' R B2 D U F2 U2 L' U2 R D B D' B2 F R' U' L R2 U2 L R2
I'm pretty mad about this, could've been sub35 without an error. It's nonlucky. Rowe might get a really sick time with this, I hope someone can send this scramble to him.

I spotted the cancellation between 1st and 2nd commutator during the solve, so it was 23 moves to solve corners. 45 for edges I think (STM).

1:04.08 gah exec mistake. Good job Ville!
Your solution is crazy and I will quit blindcubing now.
