Hi Twisty Puzzles fans,

Superclick Cube is a cube with sixteen 12.7 mm diameter spherical magnets. There are placed in the corners and core. As each pair creates a force of 2.9 kilogram, making a turn requires 4 x 2,9 = 11.6 kg of force to the solver. This makes the puzzle good for training practices for speed cubing as it trains the muscles, but requires good dexterity at the same time.

Buy the puzzle at my Shapeways Shop.

Check out the photos below.

Enjoy!

P.S. I checked YouTube analytics. My YouTube channel was watched 226.667 minutes in the last 30 days. As there are only 43.200 minutes in 30 days, this must mean that the equivalent of 5.2 people (226.667/43.200) are watching OskarPuzzle videos full time, day and night. Amazing!

It's fun to play with. I would like to introduce "biceps-tickable" here.

Hi Twisty Puzzles fans,

How much torque is needed to turn the Superclick Cube? And how does that compare to other cubes?

Today, I decided to measure some torque values. I measured three cubes.
-A commercial Rubik's brand Cube.
-My HandiCube.
-My Superclick Cube.

You can see photos of the two measurement setups below.

Measurement setup 1 used a kitchen digital weight scale and a container with about 700 gram of water. The scale was set to zero, so pulling the container up a bit results in a negative reading, corresponding to the upward pull. I connected the container with tape to the cube, turned the cube face at a 45-degrees angle and pulled the cube up until the face overcame friction and turned. This set-up was used for Rubik's Cube and Handicube.

Measurement setup 2 used a bucket of water and the cube was clamped to a table. The bucket was connected to the cube in the same way as for measurement setup 1. The bucket was gradually filled with water until the face turned. Then I measured the weight of the bucket with water on a person digital weight scale. This setup was used for Superclick Cube.

tau = r x w x a
where
tau is the torque in Newton x meter (Nm)
r is the displacement distance in meter (m)
w is the weight in kilogram (kg)
The value of a is approximately 9.8 (m x s^-2) at my house.

Rubik's Cube: r=0.039 m, w=0.20-0.25 kg --> tau=0.076-0.095 Nm
HandiCube face: r=0.041 m, w=0.09-0.12 kg --> tau=0.036-0.048 Nm
HandiCube slice: r=0.041 m, w=0.06-0.07 kg --> tau=0.024-0.026 Nm
Superclick Cube: r=0.037 m, w=7.4-7.7 kg --> tau=2.7-2.8 Nm

Note that the r value for Superclick Cube is smaller than for HandiCube. This is because the face of Superclick cube is not turned 45 degrees at maximum force, but in the order of 15 degrees.

So what do we learn from these values?
-Rubik's Cube requires about twice the torque as HandiCube for turning a face. So some 3D-printed puzzles actually turn lighter than some commercially produced ones.
-HandiCube's slice requires about 60% of the torque of Handicube's face. This explains why one can do single-handed slice moves.
-Superclick Cube requires about 30x more torque than Rubik's Cube, and about 60x more torque than HandiCube.

Enjoy this knowledge!

Oskar

P.S. Here is the conversion of the (Nm) values into (inch-ounces) for our non-metric friends. With 1 Nm = 141.6 inch-ounces, this results in the following values.
Rubik's Cube: tau=10.8-13.5 inch-ounces
HandiCube face: tau=5.1-6.8 inch-ounches
HandiCube slice: tau=3.4-3.7 inch-ounches
Superclick Cube: tau=382-397 inch-ounces

P.S. Who wants to brenchmark the tau values for commercial speed cubes, like Dayan's?

TomZ had fun with this one on DPP1 hehe. That thing took some force alright!

How close do the pairs of magnets get within the puzzle? Do they physically touch, or are they still separated by a small gap? Keep in mind that the force decreases with distance squared...

Next version: Try velcro, or superglue...

PS. I'm not sure that completely taking over the lives and minds of 5 people is supposed to be a good thing? Oskar van Deventer: You *are* the Matrix!

The spheres touch each other. Each of them is loosely contained in its cylindrical cavity.

Ok, great. Would it be possible to place a magnet in every block as well as the core, so that all 27 magnets touch their neighbours?

When I first looked at the first posting I asked myself: Where is the connection to the Disorientation cube?
I think I am happy that there is none except the symbol.

You mean putting magnets in every core and edges, as well as corresponding magnets in the core? And the goal would be to increase the required torque even more? I am not sure whether that would work. The mechanism has been designed to hold very big magnets in the corners. As a consequence, there is not too much space for a magnet in an edge.

The pieces of the two puzzles are identical, except for the core. The holes in the core of the Superclick Cube are deep enough to hold a full ball, whereas they are at half-depth for the Disorientation Cube. The symbol represents the respective mechanisms, which are fairly similar from a technical point of view, but completely different from the functional point of view.
