Constructed by HackADay user mircemk using as many 3D printed parts as possible, this self-balancing cube uses an Arduino Nano microcontroller and MPU6050 gyroscope / accelerometer to control 3 motor-driven reaction wheels to keep itself balanced — even standing on one corner on a slope! Me? I can’t stand on

This is a video from artist Rudy Willingham, who carved and photographed 80 pumpkins so that they perform Michael Jackson’s Thriller dance when viewed as a stop motion video. That’s cool. Am I going to project this onto a bedsheet in my front yard as my only Halloween decoration this

These are several photos and videos of the Halloween display created by some homeowners in East Aurora, New York, featuring a giant spider on a boom that appears to crawl down a 3-story web to the yard below. For reference, I have several pumpkins, a hay bale, and some dried

This is a video of a 3D printing technology that involves using a needle to extrude silicone objects directly into a water-based gel, so there’s no need for additional support while printing. In the video, a silicone handbag is printed by design house coperni for a show at Disneyland Paris.

Because who hasn’t dreamed of piloting their own AT-AT walker through the side of a neighbor’s house, this is a video of engineer James Bruton constructing his own roughly 7-foot tall rideable AT-AT. It moves at a snail’s pace (even slower than in the movies), but I would still proudly

This is a video of Dutch kinetic artist Theo Jansen and four of his Strandbeests he lashed together to move along the beach as one giant beest, powered by the breeze. Just look at that thing go! Next stop: training it to wave a metal detector. Pirate treasure, here I

This is a deck of cards that, when properly stacked and treated like a flipbook, show a sort of CT style scan of the human body from front to back (available HERE in some sort of quarterly science mystery box). That’s cool. And while the cards have to be in

Because dream it, and, with enough Youtube views, you can recoup the money it cost to build, this is a video of Youtuber Mr. Ho Thanh Che constructing a UFO inspired jet boat. The flying saucer shaped watercraft is powered by the same sort of motor as a jet-ski, and
