Prisma Puzzle Timer

GAH. I got it to work, but I have stackmat problems now.

ERROR: Couldn't select Stackmat Timer. Using Space Key instead.

The scrambles given in this timer seem to have more half turns than your average scrambler. Does anyone else notice this? Does it even make a difference?

For me, it often changes.

If it's random state and God's number is 20, why do I keep getting scrambles with more that 20 moves?

Random-state =/= optimal

 

[TheMachanga]

Random-state =/= optimal

Then what's random state?

 

[Rpotts]

A random state on the cube bears little or no resemblance to a partially solved cube (such as blocks built, many pieces oriented/permuted)

optimal means fewest number of moves to get to said optimal state. An optimal random state scrambler would produce only scrambles of depth 20 or fewer. However, a random state non-optimal scrambler (such as the one in Puzzle Timer) will produce the same random states in a suboptimal scramble. (>20 moves)

Great work.

Thanks

The simplest way to put how it scrambles the cube is:

Generates a random position that the cube can get to,
Finds a solution to turn a solved cube into that position.

If it were optimal, this would take significantly longer so for convenience it's far easier for it to not necessarily be optimal.

Also, how can I edit these db files? As they won't import into excel or access for me. I would like to import my Bellon timer sessions.

It's a custom file format used by H2 database. You can use the "Add solutions..." dialog in the history window to import time/scrambles from other timers.

Has anyone figured out the Stackmat Error thing?

 

[Walter Souza]

Just go with the standard American 3x3 scheme, for all cubical puzzles. I don't think very many fast people are used to Meffert's skewb scheme. The user can always customize this later if they want (right?)

The Mefferts scheme for the one I got is:

F: Green
B: Blue
U: Yellow
D: Orange
L: Red
R: Pink

So if we include skewb as an official event my skrewb should be scrambled with green front and yellow top as yellow is the lightest color in my scheme.

So I'll stick with the current color scheme. "Kirjava-Meep method" website uses it too.

Would implementing a metronome be any trouble?

You can use an external program for that. This one is pretty good: http://www.metronomeonline.com/.

Put everything everyone wants in the timer!

Are you having trouble with the stackmat timer? What is happening exactly?

I bet that was how CCT ended up with an IRC client.

The next release is almost done. Here is the changelog (main features in bold).

Name:

Puzzle Timer definitely needs a proper name. What about Prisma Puzzle Timer (prisma means prism in portuguese)? How does it sound?

Bug fixes:

• Stackmat timer inverted signal support
• Time rounding
• Time parsing
• Pyraminx tips solver

New features:

• Pratical manual time input (Ctrl + A, type time, Enter)
• Inspection time (works with stackmat timer)

Puzzles:

• Skewb
• Floppy cube (1x3x3)
• Slim tower (2x2x3)
• Rubik's tower (2x2x4)
• Rubik's domino (2x3x3)

Scramblers:

• 2x2x2 <U, R, F>
• 2x2x2 fixed length random state scrambler
• 3x3x3 orientation / permutation training
• 3x3x3 <U, L> / <U, R>
• Pyraminx fixed length random state scrambler
• Square-1 random state scrambler
• Square-1 cube shape scrambler
• Skewb random state scrambler
• Floppy cube (1x3x3) random state scrambler
• Slim tower (2x2x3) random state scrambler
• Rubik's tower (2x2x4) random state scrambler
• Rubik's domino (2x3x3) random state scrambler

Statistics:

• Interquartile mean

Polishing:

• Partial scramble highlighting
• More useful statistics in main window
• Input device selection restarts stackmat timer

Suggestions?

I connect my stackmat, then I go to options, timer trigger, stackmat timer, then I get the error message.

 

[JonnyWhoopes]

For the name, perhaps just Prisma Timer? The "puzzle" seems rather... unnecessary. Prisma Timer seems to flow well. =)

Question: Where it says Mean:m is that the session average? If not, what is?
