University of Michigan mechanical engineering students have built "the world's largest hand-solvable, stationary" Rubik's Cube. Fashioned primarily from aluminum, it weighs 1,500 pounds but can be manipulated by one person. The puzzle is available for solving in the campus's mechanical engineering building. From Michigan Engineering:
They realized they couldn’t simply scale up the approach a handheld cube relies on because the friction would be too great. So to keep friction minimal, they devised a setup that utilizes rollers and transfer bearings.
“This is a truly amazing and unique kinematic mechanism that functions as a Rubik's cube,” said Noel Perkins, the Donald T. Greenwood Collegiate Professor of Mechanical Engineering and advisor to the students.
“There is no other human-manipulable cube like this, to the best of our knowledge. That said, it is not technically the largest cube. We're aware of a larger cube that requires the user to literally roll it on the ground to solve and rotate the faces. None of that is required by our stationary design. So to be very precise, it is the world's largest stationary, human manipulable Rubik's cube.”
Mats Valk used a custom Rubik’s Cube tricked out with neodymium magnets to set a new world record for speed cubing: 4.74 seconds.
In this Scientific American video, Rubik’s Cube master Ian Scheffler, author of the new book Cracking the Cube, explains some of the math behind “speedcubing.” Scheduler’s book sounds fascinating even though the only way I could get my Rubik’s Cube solved is to hand it to my 10-year-old son’s friend Luc who was the first […]
Wait for the amazing happiness at the end.
While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]

It’s currently available in the Boing Boing Store.The Trakk Bullet offers the same wireless convenience as other portable speakers, but few are built as tough as this one. Its utilitarian construction is designed to be a totally low-maintenance […]
The Ticwatch 2 Active Smartwatch is a simpler take on an active wearable that raised over $2m dollars on Kickstarter and is currently offered in the Boing Boing Store.Somewhere in between the single-day battery life and platform-specificity of the Apple Watch and Android Wear devices, there exists the Ticwatch. Instead of trying to shoehorn another […]
