Pictures! And information on where we can get some of those magnets!

Details:

Ring magnets: N50 strength, 5mm outer diameter, 1.5mm inner diameter, 1.5mm height. I've seen various calculations for how these differ from normal 4x2s. (4mm diameter, 2mm height) I bought mine off ebay, from a chinese seller. I'd written them off as gone, and then they arrived.

If you see any video on magnetizing "The Valk" the magnet positions are 100% standard, I took them from DMCubing's videos. There's actually very little option on how to do it due to the shape of the cube. The 5mm magnet size has no impact on positioning really, except to really force the position in the edge piece even more than normal. (There isn't much space to locate the magnet, by the end, I probably could have placed them totally by sight.)

My guess is that my "sweet spot" for the magnets is a bit larger than normal due to the magnets used. Also I don't find it as hard to move as my N50 4mmx2mm based Gans 356v2. If people are interested, I can see about pulling apart an edge + corner... but I hate the thought of pulling the corners apart, those little tabs are fragile For edges, it isn't a real issue... so I might just do an edge.

Blu Tack made positioning the magnets MUCH easier, in that if I made a mistake, I could just undo it... with super glue, I probably would have lost 2-3 pieces, at least. I'd recommend it to anyone magnetizing a cube for the first time!

I've watched the video of my 3BLD PB from Manchester and there was a pause of over 20s while I recalled my first word...

I've run across this too much in memo already so time to try to nip it in the bud. I'm just tracking two short linear "stories", one for corners and one for edges. If I view it like any linked list it's a matter of keeping a handle to the head node, so I'm trying to visualize an "opening scene" to each story, maybe with a dramatic fade/pan. If I haven't lost the head node the rest usually does its business.

Yeah that's a good approach. Noah calls it a keystone.

When using rooms I would usually put the first part of the image on the door and if not then I focus on the first word which I thought I'd done here. I knew the rest of the image but blanked the first one. I was wrong when I said it was DEATH. It was JACK (JK) who S**T (XT) on DEATH (DQ) in front of WONDER WOMAN (W) who was sat on a LOG (LG) - I think.
Windows Movie Maker is doing the job @mark49152. I just need a little free time to finish it off.

Okay I'm looking back at the published scramble for my first 3BLD DNF from Sunday:

R2 U2 B2 F2 U' L2 F2 R2 F' R D' B2 R F L B' D' U2 B2 Rw2

Solving with my usual F:Green and U:Yellow, I can recall my memo as:

CT OU JQ SL R-
(Chris Tarrant was studying at the Open University, writing a JQuery about Sierra Leone using the variable "R")

PG WV BI SN
(Parental Guidance prevents me learning Winter Variation, so I'll ride a BIcycle into the SuN.)

Now something seems to not be correct here as I have an odd number of edge targets and an even number of corner targets. Not sure what I did in the actual solve (can't even remember if I attempted to execute Parity or not) but I certainly made at least a couple of execution errors.

When I attempt to execute this sighted without applying Parity it solves correctly (basic OP for edges and corners):

y2 // inspection

I'm confused. What have I done wrong here? I think I've been a plonker and there's something fundamental I'm misunderstanding about BLD. Cheers.

Do you use Speffz? I get a completely different solve.
Edit: Where do I get the scrambles BTW?

I use Speffz as I understand it, yes. e.g.: my first target, C is at UF, then T is at BL. I've linked my solution to algdb so you can follow.

Scrambles are at http://wcadb.net/results.php?id=ManchesterOpen2017.

I saw the WuJi on LighTake and at 10% discount and I had to get one. Also the MF3RS was so cheap at $1.99 each and I've heard that it is the best budget 3x3 and a good option for MBLD so I ordered 6 of them. I don't think I'll ever do more than that at multi in my whole life. I hope it was a wise choice, as a while ago I was considering buying several Thunderclap v1 but ended up not getting them. All the cubes in stickerless of course.

@Shaky Hands, I get a completely different memo too.

I dont know speffz but you're right - there's parity. So the corners must be odd as well as edges. Nice scramble anyway.

http://scrambld.cubing.net/ ; if you want the answer... input the scramble there.

I have a hacked version that hides the solution from me, until I click an "unhide" button. It is useful for making sure I start learning memo right .

 

[Shaky Hands]

@phreaker, thanks but unless I'm mistaken, it can't do the edges using OP, only corners.

 

[phreaker]

@phreaker, thanks but unless I'm mistaken, it can't do the edges using OP, only corners.

It is M2. But it can check your memo, that doesn't change.

I'll probably just learn M2 to start. Simpler that way.

My ao5 from Olsztyn Open.

 

[Shaky Hands]

But isn't the buffer is in a different position so I'm shooting at different targets?

I don't disagree. I did have a good look at M2 last night.

 

[phreaker]

That makes sense... my bad. I don't know the location of the OP buffer.

M2 doesn't look THAT bad. Noah's tutorial on it is quite good, and there's a ton of info on it.

 

[Shaky Hands]

Does this help explain how I'm tracking the pieces?

Sorry about the angle.

 

[Shaky Hands]

That makes sense... my bad. I don't know the location of the OP buffer.

OP edge buffer is at UR (Speffz B).

 

[newtonbase]

Our letter systems are different. BL edge is R for me. Also, your original post said you do white on top! I'll look at your video in more detail when the kids are in bed.

 

[Shaky Hands]

Sorry Mark, you're quite right. I've corrected the U face to Yellow on the original post.

And you're right, in Speffz BL is R and BR is T. For some reason they've gone into my head the other way. I'll need to fix this in my head as BUL is R and BDR is T for corners, which is correct. And there you have it, insight into a weary brain!
