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.
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.
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.
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.
French artist Parse/Error created a machine to produce his rhythmic and undulating line drawings. The designer conceives each image on a computer, while the machine acts as his hands and outputs his work. You can purchase original drawings in the Parse/Error shop.
Did you know that plastic bottles are blown like glass? Us neither. Here’s a look at a fascinating machine which takes small plastic tubes, heats them up, and then blows them into a mold to make water bottles. The same basic process is even used for big 5-gallon bottles.
LEGO machine maker JK Brickworks follows up last year’s Halloween candy dispenser with an even better one. His latest machine spins round and round, and flings candy bars at the kids. Want one? Buy the LEGO 17101 BOOST Creative Toolbox, and follow the directions here.
Yoshihito Isogawa shows off another impressive build. He used LEGO Technic and Mindstorms parts, along with mirrors and a laser pointer to create a mechanism that can project laser patterns on the wall by rapidly modulating its reflector. Here’s another variant he also made.
A wonderfully satisfying bit of engineering porn showing off a slick modular tooling machine. The Bihler Leantool system is used in factories to form and cut wire and rolled metal into precisely bent shapes, such as chain links, hooks, and other small, high volume parts.
