three sub-minute solves (on video)

After achieving two sub-minute personal bests last week, I feared that they perhaps were flukes.  The off-camera aspect irked me, as well.  So, donning the GoPro, I gave it another shot last night and logged three sub-minute solves:

At 52, 58, and 58 seconds, these were the best 3 of 5 — after tossing out a sixth lucky solve (with OLL solving the cube completely).  I wound up with a 60.8 second 5-solve average.  I actually was on pace for a sub-50 solve when my F-II popped.  Bummer.  All three recorded solves were on a sticklerless Dayan Zhanchi.

first timed 2×2 (27 seconds)

Having spent the last couple months consumed by 3×3 cubes, I just grabbed a 2×2 to break up the monotony. As expected, it didn’t take long to become comfortable with it. After all, a 2×2 cube is simply a 3×3 cube without the edges. After about 20 minutes for practice, I recorded this 27-second solve:

Pure Beginner’s Method adapted to a 2×2. The OLL was a little clunky, and I’m sure there are some more efficient algorithms. The PLL was a snap.

The music is Umphrey’s McGee playing, appropriately, “2×2” (from their December 30, 2010 concert). The full show can be downloaded here.

The cube is a V-Cube 2. It seems to lock up a bunch, especially when compared to the better 3×3’s I own. But it’s certainly smooth enough to serve as a fun distraction.

two sub-minute solves (personal bests)

Lately, my morning routine at work (about 7:20-7:25) has me shaking off the cobwebs with a freshly-brewed dopio and a couple cube solves.  I haven’t timed myself in a couple weeks, as I’ve concentrated instead on more advanced techniques.  But, for some reason this morning, I decided to load cubetimer.com.  Suddenly, I logged my two personal bests:

I first logged a 52-second solve with a black Dayan Zhanchi, shaving a full 17 seconds of my previous record.  Then, pressing my luck, I logged a 58-second solve on a stickerless Dayan LunHui (my new favorite cube).

These were using the advanced cross technique about which I just wrote, but otherwise basic Beginner’s Method.  No F2L.

advancing the cross

For the most part, I still currently use the Beginner’s Method (as taught by RobH0629‘s very accessible and excellent tutorials) to solve a 3×3 cube.  Although I’m amazed that I’ve gotten down to 1:09 using that method, I realize that I’ll need more advanced techniques to cut my times.  For example, on even my fastest solves, the cross takes me an average of 15 seconds; with new techniques, I should be able to halve that.

When I say cross, I mean forming a cross/plus-sign in the bottom face (usually white) by placing the white/red, white/blue, white/orange, white/green edges with their white halves facing down and colored halves lined up with each side face’s center cube.  Like so:

magnetic dice cube

I frequently use CubeTimer.com to time my solves.  I just noticed a “Links” link above the timer, clicked it, and stumbed onto MagneticCube.com — which sells, not suprisingly, magnetic cubes.

The video below shows how they work. Although it appears to require quite a bit of force to turn each layer, it is still a very clever concept.

With a $59 price tag, it’s probably not the resistance that will keep me from buying one.  But a really cool novelty cube nevertheless. (Perhaps I’ll hazard the DIY project one day….)
