OLL 56 Slo-Mo (iPhone 240fps) [I’m Stil Here]

Adventures in Cubing1 Comment
UPDATED: As mentioned in this post, I’ve updated my algorithm for this case to (r’ U’ r) (U’ R’ U R) (U’ R’ U R) (r’ U r).

Three posts for all of 2015. That was it. Three. That wasn’t some fancy Rule of Three dramatic device. Not at all. Just. Plain. Busy.

OLL 56
(spinner/streetlights)

(r U r’ U) (R U’ R’) M’ U (R U2 r’)

setup: (r U r’) (R U R’ U’) (R U R’ U’) (r U’ r’)

There were months at a time that I didn’t even pick up a cube, let alone post. But never fear: In the infamous* words of John Hartford, I’m still here.

* by which I mean neither the Three Amigos’ “more than famous” nor the literal “well known for some bad quality or deed,” but rather “not really famous at all.”

This one relates to OLL 56, one of the bar or I-shaped OLLs. As I learn the full set of bar OLLs this emerged as one where the standard alg — (r U r') U (R U' R') U (R U' R') (r U' r') — could be improved by an M-slice. Yes, I’m a self-proclaimed M- and S-slice evangelist. And, yes, I’ll admit that sometimes using the middle slices is more neat and clever than ultimately useful. (The S-slice alg for F2L edge flip probably should be Exhibit 1.) But OLL 56 really does get easier with an M slice dropped in. Here’s a video showing the execution at full-speed and in slomo:

It may not be for everyone, but it’s much easier for me. Full bar OLL tutorial coming soon….

iPhone 240fps Slo-Mo (Ja Perm)

Yes, another quickie slomo video. Ja Perm:

(R’ U2) (R U R’) z R2 (U R’) D (R U’)

I don’t think this iteration is that common, but it’s been my go-to since I stumbled onto it ages ago.

(music: Beats Antique, “Cat Skillz”; cube: Maru CX3)

The key with this one is the z rotation, which converts into more manageable U and D moves what would otherwise be alternating R and L moves. I don’t execute the z as a full rotation, but just enough that my right hand can execute the “coverted” moves.

iPhone 240fps Slo-Mo (H Perm)

Another slo-mo PLL iPhone video? Maybe this will become a series, after all….

HH was the very first one-look PLL I learned. It forced me to learn M slice flicks for the four M2′ combos, each of which I executed as two single M’ flicks. Soon thereafter I learned double-M’ flicks (pulling back to front across the bottom with my ring then middle finger), allowing much faster execution. Although I also learned double-U flicks, I couldn’t get my right hand fingers into position for those doubles while holding the cube in a way that allowed for the double-M’s. So, I would do double M’s and paired single Us. I eventually learned the M-based U Perms which relied on a mix of U and U’ as shown in this slomo video. Last week, a lot of folks commented that my Ub push/pull finger trick on the U layer was innovative.

What if I used that same trick for the H Perm, like so:

M2′ U’ M2′ U2 M2′ U’ M2′

Turns out, it works quite well.

(music: TAUK, “Sweet Revenge”; cube: Maru CX3)

My left hand index finger executes the U’ by pulling left to right across the front. That puts the index finger in a position to push right to left for the U2, and in a position to do the second U’ like the first. The only challenge was that muscle memory kept telling my left hand to move the M layer as though I was doing a Ub perm. A couple days in, the synapses have adapted and separated the two. My execution is good, but there’s speed to be gained.

Puzzle Collection (June 2014)

I’ve received tons of requests to put together a video showcasing my puzzle collection. I’ve resisted for a while, since I frankly don’t find it that interesting to watch someone talk — and for thirty minutes at that!?! — about their puzzles. But, as one subscriber noted, I do have a few unique cubes in the collection. So, why not? Here’s a video of my puzzle collection as of June 2014:
