Machine shop DataPro shares hypnotic time-lapse footage of a Datron CNC milling machine, as it takes a disc of aluminum and transforms it into a precise and smoothly formed gear. It was shot as a time-lapse, but won’t it be awesome when machines can do this in real time?
We’ve seen industrial machines that can bend wires into shapes, but thanks to 3D printing and low-cost controllers like Arduino, you can make your own desktop machine now. How to Mechatronics shows us exactly how. Grab the full instructions, models, code, and schematics here.
Martin Molin is known for his amazing Wintergatan music-making marble machine. He’s been working on an even more complicated machine for years, and has been documenting the build. This conveyor belt assembly is one of the more enthralling parts he’s completed so far.
Hypnotic video footage of a rocket propellant tank being made by wrapping and weaving layers of carbon composite filament around an aluminum form. The custom-built machine and software were engineered by the literal rocket scientists at Interorbital Systems.
One of the more impressive LEGO Great Ball Contraptions we’ve seen turned up at Japan Brickfest 2018. Among its contributors was Akiyuky, whose modules wowed the crowd with all manner of hypnotically moving parts, while his LEGO Technic railway shuttled balls alongside.
The Q takes a gamble with this build – a fully-functional slot machine built from cardboard, popsicle sticks, and hot glue. We love the detail he included on the reels to make it look like the real deal. Stick around for a few other fun DIY builds in this compilation video.
Tearing down LEGO buildings usually requires plucking bricks off by hand. But Shadow Elenter’s approach is way cooler. He built a crane to do his demolition, using LEGO Technic parts and 18 motors. It can lift items, knock them down, and claw or break them apart.
Heads or Tales Coins & Collectibles presents a wonderfully satisfying video showing a laser etching machine making a cold storage coin – a physical manifestation of cryptocurrency. These coins feature a unique private key which can be used to unlock its bearer’s Bitcoins.
It’s a requisite stop for every kid with change in their pocket. But have you ever wondered how dropping a coin into a gumball machine makes it dispense a chewy treat? Animator and explainer of things Jared Owen gives us a detailed breakdown of its mechanism.
A mesmerizing look at a machine designed for the high-speed production of paper cups. It starts out with flat sheets of paper, rolls them onto a form, glues the seam, then adds the bottom, and eventually rolls the top edge, cranking out as many as 130 cups per minute.
A look inside the P. van der Wegen Gear factory, where they make enormous gears for mining applications. While the process of milling these massive parts is truly fascinating, we can only imagine what they look like when in use in the machinery they’re destined for.
In this promotional spot for CAD/CAM software developer Open Mind, they demonstrate how a 5-axis CNC mill can transform a solid block of metal into a replica of a basketball net, by gradually carving away bits of metal until only a woven net remains. Skip to 1:06.
A wonderfully satisfying bit of engineering wizardry. What you’re looking at is a specialized industrial machine which spins a roll of plastic wrap around a freshly-milled steel coil until it’s fully protected for shipment. Here’s a slightly more sleepy look at a similar machine.
A brief demonstration of a rare piece of office equipment c. 1953. The Keaton Music Typewriter made it relatively easy to create sheet music much in the same way you’d type a letter. If you made a mistake, however, you’d have to wait until 1956 for correction fluid to be invented.
LEGO master Shadow Elenter shows off another impressive Technic build. His latest creation is a Howitzer style tank that weighs in at 12 pounds. It has working treads, and some amazing weaponry, including a massive gun that plants itself to handle its recoil.
ft Robotics shows off a nifty Arduino Mega and Fischertechnik based plotter. Unlike other drawing machines which are driven by cartesian coordinates, this one uses polar coordinates. It draws by moving a pen along one axis, while a turntable rotates beneath its retractable pen.
