Watch this self-solving Rubik’s cube march its way across a table

This wild, 3D-printed self-solving Rubik’s cube is amazing. To make it work, a Japanese inventor used servo motors and Arduino boards to actuate the cube as it solves itself. Sadly, there isn’t much of a build description available but it looks to be very compact and surprisingly fast.
There is a description of the project on DMM-Make and you can watch the little cube scoot around a table as it solves itself in less than a minute. The creator also built the Human Controller, a cute system for controlling a human as they walk down the street, and the Human Crane Game which is equally inexplicable. If this Ru-bot is real and ready for prime time it could be an amazing Kickstarter.

Buckyballs are back

Buckyballs are back
Years ago – six years ago, to be exact – a toy called Buckyballs came under attack by government officials intent on destroying fun. The Consumer Product Safety Commission banned the toys, which we noted were tiny rare earth magnets that were good for play but bad for a snack, because a few overzealous children swallowed one or two and found themselves in gastrointestinal distress.
The lawsuit against ZenMagnets, creators of Buckyballs, began as a “recall prior to record of injury,” something unprecedented in this space. That meant the company had to stop selling its magnets before anyone was actually injured, an odd position for a small company to be in.
Now, after six years of battle, Buckyballs are back. The company is now able to sell its biggest set, the Mandala and notes that the sets are not toys. They could cause intestinal pinching, writes the ZenMagnets team, and they recommend not leaving them around animals or small children. However, these odd and wonderful little toys are finally available for purchase. The kit now even comes inside a lockable box to ensure little hands can’t accidentally grab and eat them.
“We remain willing to work with the CPSC to develop the magnet safety standards for which we’ve already petitioned, and which will be more effective and reasonable than the all-ages, nationwide ban we succeeded in vacating in the Tenth Circuit,” wrote founder Shihan Qu. “As we’ve already been doing, Zen Magnets looks forward to providing not just the highest quality magnet spheres on the market, but also the safest in terms of sales methods and warnings. Now that the war on magnets is over, hopefully we can all focus towards the war on magnet misuse.”
“Magnets must be respected, but need not be feared,” he said. Truer words – besides these – were never spoken.

This robot can solve a Rubik’s Cube in .38 seconds

This robot can solve a Rubik’s Cube in .38 seconds
When future generations look back on 2018 what will they remember? Not much, I suspect, except for this amazing robot that can solve a Rubik’s cube in .38 seconds. The video, above, shows the cube in an unsolved position and then the actuators jump into action, slamming squares into place like some kind of crazed […]
