Weilong Extra Torpedo

So Today I picked up my mini Weilong and it rattled. Well turns out that inside one of the edges was an extra torpedo. Just thought I'd share.

 

[Lchu613]

Haha nice, I guess you won't have to worry about losing a torpedo. Wonder how that happened.

 

[antoineccantin]

So that's where my torpedo disappeared to!

Good angle?

I realise you undid the moves at the start, but if this wasn't a test video that would be dumb. You did some mobes, undid them, then redid them. Instead get a new scramble.

Also angle isn't great IMO. Would be good for tutorials but your old angle was better + showed the timer.

Eh I would disagree. If I have a timer fail and forget to reset stackmat or something, I'll undo moves if I've only done a couple. It's not a major deal and I generally ignore those unless I'm doing comp practice.

Solved a random <Rw,U> scramble on the 4x4x4 in 2:36.70.

Scramble: U2 r' U r' U' r U2 r' U2 r U r' U2 r U' r U r' U r' U' r U2 r U r' U r' U r2 U2 r' U r' U2 r U' r U r' U2 r U' r' U r U r U' r

Method:

Spoiler

1) Intuitively pair up and solve DR edge.
2) Intuitively pair up and solve BR edge. Then pair DBR with DBr and insert them (r'U2rU2 stuff).
3) Solve remaining corners with U and r(U^n)r' triggers.
4) Solve edges using this 2-cycle (flip UR edge): r' U' r U' r U' r2 U2 r2 U' r U2 r' U2 r U2 r U r U r' U' r U2 r'
5) Solve centers using this 3-cycle (Ufr->Fru->Ufl): r U2 r' U' r U' r2 U2 r2 U r' U' r' U2 r U r' U r2 U2 r2 U' r

I think a few degrees higher and you should be able to get the cube and the timer in there I don't know how adjustable GoPro cameras are though, so may be impossible...

Just got this (got pretty lucky with the centres):

edit: 1:53.380

Move optimal 5x5 <r,U> pure parity (33 moves)

also a pretty nice regripless 4x4 <r,U> adjacent pll parity alg

 

[qqwref]

1:52.34 after many tries (also 2:18.84 avg5 = 2:33.37, 2:18.79, 2:04.37+, (2:37.98), (1:52.34)).

You guys should now try it with 5x5

It's easy because the midges and the + centres are bandaged together so you just need a U perm, which is easy anyway because you can just treat it like 3x3x2 <R,U>.

I think 5x5 r, U> would probably be a lot harder but I haven't tried it yet.

 

[bobthegiraffemonkey]

Decided to sort out my double parity algs and learn them (especially for 5x5), and was reminded of an idea I had a while back for 4x4 parity but didn't post. I never stuck with it, but it might have potential.

If you can tell you have OLL parity before LS, then you can insert the edge flipped, and with a wrong corner with the U sticker on D (basically a U layer corner upside-down), then solve OLL treating the D sticker of the F2L corner as a U sticker. Then either:
-Inspect for PLL parity, and fix the edge and two wrong corners with either OLL parity or double parity to leave a non-parity PLL case. I think I found a few tricks to influence/solve CP at the same time.
-Do a PLL to either solve LL (apart from the wrong corner), or to leave 2 swapped edges opposite each other. Then fix as above.

Pro: don't need to use 2 parity algs in a single solve.
Con: recognition might be awkward but probably doable. Having a wrong corner is confusing.

P.S. I plan to use these for DP: (F2 x) l2' U2 l U2 l' U2 l U2' (B2 x2') r U2 r U2' (r' l') / (F2 x) l2' U2 3l U2 3l' U2 3l U2' (B2 x2') r U2 3r U2' (r' 3l').

A Chinese company is now 3D printing houses. That's right, full-size houses. Does anyone wanna spend a few thousand bucks and try to get them to 3D print the world's largest twisty puzzle? Since it's 3D printed, it can be any kind of design

 

[Tim Major]

Crowd fund a huge functional 3x3!

Would need a special design for turning, or to have it suspended from the centre pieces?

We should hit up Moyu and get permission to base it off of the WeiLong

Or, hit up Oskar van Deventer and get his permission to make a 65x65x65 based off of his 17x17x17 design

Rw2' F2 R2 U' R2' F2 Rw2 U'

Pretty fast 3-cycle that works on 3x3x3 and 3x3x2.
