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:
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.
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….
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….
I’m still here. Work travel, family vacation, the kids back in school, and soccer season starting. All of a sudden a month passes….
As I get back into the swing of things, I wanted to make this quick video showcasing my new custom cubing mat and previewing a few projects and tutorials queued up for the next few weeks:
As described in the video, the mat design is a simple “segment” from the denser cube patent composite poster I had made last year. The centerpiece is the main US patent issued to Erno Rubik in 1983, based, as it were, on his 1978 Hungarian patent. I set it up on graph paper to make it seem like an engineer’s sketch, laid it out on a bias, and did a full-bleed to make it more modern. After some debate, I decided to make the background gray, rather than black. The reduced contrast would make it less distracting as a background for videos, I figured.
I ordered the 14″ x 24″ mat from Inked Playmats for $24. Their service was great, and the mat arrived three days after I updloaded the art. The quality matches a standard mousepad, but is much thinner (at about 1/16″). I’d definitely recommend the Inked Playmats.
In my last post on my color scheme, I focussed on The Cubicle. I mentioned but didn’t really discuss The Cube Specialists. This video showcases my sticker collection and organization and highlights the excellent stickers from the Cube Specialists:
