Another slo-mo PLL iPhone video? Maybe this will become a series, after all….
H 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:
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.
It seems that iPhone 6 slo-mo videos are all the rage these days. Why not jump on the bandwagon? No doubt slow-motion is useful for teaching new algs and finger tricks. Here’s a quick proof of concept based around my execution of the U-Perms:
Not bad for a phone, eh? Although this was shot under the same light as my other videos, it does appear darker and noisier (with the sensor trying to compensate). It seems that the 240fps frame rate does drop the total light processed by a good 50%. I’ll need to blast it with light next time.
I have an ambitious plan up my sleeves for a video based around the slo-mo feature. But with the clunky workflow (needing to pass the video through the iMovie app before offloading for editing in FCPX), it might be a while before I find a solid uninterrupted block of time for it.
P.S. I just recorded a similar video for the Nb Perm (z D’ (R U’ R2′) D (R’ U D’) (R U’ R2′) D (R’ U R) z’):
For a while now, I’ve had a decent alg for flipping a placed but misoriented F2L edge: r (R U R’ U’) r’ U2 (R U R U’ R2). As I wrote earlier, this is a “purer” alternative — in that it does not affect the orientation of the U corners — to the standard algs of R’ U S’ U’ (R B’ R’) S R B and (R U R’ U’) (U’ R U2 R’) d (R’U’R). It’s regripless and fairly fast, but still a bit a clunky.
While learning an S-slice alternative to another F2L case (coming soon), it occurred to me that S may open up possibilities here, too. I reached out to TellerWest, king of tricked out algs, and we identified this as possibility:
I’m fairly meticulous when it comes to learning new algorithms, especially OLLs. My first stop is usually the speedsolving wiki OLL page. But beware: Rarely is the first algorithm for each case the best. The most common or most obvious, perhaps. But rarely the best.
Such was definitely the case with the Sidewinder (OLL 25). The first algorithm listed required a four-move setup, two Sexy Moves, and then a closing three-move trigger. The second one is equally clunky. But then the third is short and sweet. It starts with a y2, but that’s not really any different than just treating a different orientation as “home” for the case. After a few minutes of experimenting, it became obvious that the third option was the most efficient, lending itself to easy finger tricks. Continue reading →
My last tutorial focussed on the Frying Pan OLLs, which I described as the two L-shape patterns with a bar on the side. A youtube commenter quickly pointed out that there were, in fact, four L-shape OLLs with a bar on the side– the two Frying Pan ones (##53-54) and the two Squeezy ones (##49-50). I promised to do a new tutorial that added the Squeezies. Then I realized that there are a total of only six L-shape cases. So, why not add the Breaknecks (##47-48), too, and make it a comprehensive L-shape OLL tutorial?
The video below does just that. While the algorithms are not necessarily hard to execute — for the Squeezies, it’s just about finding the right finger-tricks and flow — the six cases are easy to confuse. Below the video are the algs and some simple rules to help distinguish and orient the cases.
