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.

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.

AoChuang 5×5 Re-Stickering (Time Lapse)

It’s not easy to make a re-stickering video interesting. So, why make one at all? In this case, it was an excuse to test the iPhone 6 time lapse feature. Here’s about 30 minutes of scraping, cleaning, and stickering a Moyu AoChuang 5×5 reduced to 100 seconds.

The puzzle and stickers are from The Cubicle in my standard scheme. The cube looks great and performs even better. Easily the best 5×5 out there. Perfectly suited for me, the worst 5×5 solver out there....

iPhone 240fps Slo-Mo (U Perms)

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’):

Maybe I’ll consider a series of these....

S-Slice: F2L Edge Flip

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’ R’) d (R’ U2 R) U2′ (R’ U R) 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:

R’ U S’ U’ (R B’ R’) S R B

As shown in this video, it works quite well:

S moves are not that easy nor natural for a lot of folks. Continue reading

Excuses: 34-Sec Ao5

It just takes an on-camera 34-second Ao5 (this one as a submission for Paradox Cubing’s 10k Subscriber Contest) to remind me that well, uh, I kinda suck at this cubing thing. I know that 34 seconds is impressive to 99.9% of the general population. But three years into this thing, I should be at speedsolving levels, and 34-seconds isn’t really there.

Nevertheless, since I’ve never been bashful about being mediocre and it not really bothering me, I figure that I might as well post the average. But then to show that, gee, maybe I am a wee bit self-conscious about the time, I’ll follow up with an excuse video.

Sucky, right? And in multiple different ways:
