 Post subject: Mèffert 1982 pyraminx catalog
PostPosted: Tue Apr 09, 2002 12:37 pm 
as promised a while back I have scanned
Mèffert's 1982 puzzle catalog:

Image

the cover and pages 1-6 may be found at

http://crypto.cs.mcgill.ca/~crepeau/CATALOG%2082/

I skipped the remaining pages (7,8,9) because
the puzzles on those pages where not 3D style.

Enjoy !

This may of been covered in a prior posting but did
Meffert actually make all these puzzles? There are some that I have never seen before.

Any word on his plans for "new" puzzles in 2002?

That is really neat! It's just a pity that so many of them weren't made.

BTW, it looks like an alien Homer Simpson on the cover...

At least 2 of the puzzles in that catalogue can be made from currently existing mechanisms, too. The "Pyraminx Ultimate" is basically just a Professor's Cube without edge pieces (just have the puzzle down in the same fashion as the "Pillow Cube"), and the "Pyraminx Crystal" is simply a Megaminx without centres. Simply create a track on the edges and corners for the centres to slide through, have the edges puff out instead of in, and implode the corners slightly, and bingo! You've got your Crystal. :) L8r.

From what I've read about the evolution of the puzzles, that's actually the "kernel" of the 5x5x5 mechanism. Check out patent US4600199.

I would be happy to show any pictures of the buildups I did, if anyone is interested. I have nowhere to post them but can send them.

The pyraminx crystal doesnt work the same way as the megaminx. A single twist doesnt just send 5 corners and 5 edges in a 5-cycle. It moves a lot more pieces than that...

 Post subject: Pyraminx magic tetrahedron
PostPosted: Wed Apr 10, 2002 6:37 am 
Thanks for this catalog. I have been dying to take a look at it and printed the scanned images out on a color laser printer at work as soon as I saw them! I recently made a jumbo sized pyraminx magic tetrahedron based on a build up of a diamond skewb. At the same time made a jumbo sized mental block also based on a skewb buildup. I wonder, how easy would it be to make a pyraminx ultimate without shaving too much off of a 5x5 so as to destroy the mechanism? It definitely should go into my queue of puzzle projects though. I forgot, does anyone know if any of these unusual puzzles in this catalog were ever made even in the smallest quantities?

Take a close look at the "undiscovered" puzzles. They have a light line in the cuts. The general shape shows that these are cardboard mockups.

Pity they didn't eventuate.

Judging from the pictures, it looks like a single turn moves 5 pieces and 10 edges, the difference being caused by the shapes of the edges (poofing outwards instead of in), but it should be as "easy" to adapt a Megaminx puzzle to this new system as I posted in my earlier message. Please correct me if I'm wrong. L8r.

 Post subject: Unmade puzzles
PostPosted: Thu Apr 11, 2002 1:13 am 
Has anyone looked into makeing some of the unmade ones? I would try mut my to do list is a mile long, and my done list doesn't exist yet. Someone should do it though, also has anyone thought about a pyraminx square? Basicly it would look like a Rubik's Cube but it wouldn't have full freedom of movement, i.e. only two sides would be able to make 90º turns, the others would make 180º turns, it seems to be in the natural progresion of the unmade pryiminx polygons. How would the restricted movement affect the puzzle?

Actually, this puzzle is Part of UDO KRELL's 5x5 patyent, Figures # 1-5 are the main pics of it...
Its quite simple to make, and would take a good hour to do. Just take a saw to a 5x5.
What i want to know, is how to make krell's other puzzle he described... figure #25 (yes. i have a copy of the patent in front of me :) )
Its simple. but one part confuses me. It takes:
1 corner
3 wings
3 inner pieces (not cross)
that are part of one corner. so basically, a 2x2x2 section and truncates it so that it becomes only 6 pieces.
He hides the corner somehow, and i cant figure it out. I understand how, but then how does the inner corner thingy stay in? Confusing...

There is also a 12 sided thing in tehre that looks like pyraminx crytal.
Another thing i just noticed, there is a 26 sided diamond cube 5x5. figure 24h

If anyone wants a Pyraminx Ultimate, email me

I believe the crystal is supposed to work by cutting right through the centre. An incredibly complicated mech.
