It’s both a useful packing material and a wonderful plaything for fidgeters like us. Now go inside Sealed Air’s factory and see how they make their official BubbleWrap brand bubble wrap. It’s interesting that the first bubble wrap machine was designed to make wallpaper.
If you thought The Citadel was complex, check out builder Samuel Hunt’s insanely complex K’NEX ball machine. It’s made from over 50,000 pieces, has 6 networks, 33 paths, and 13 lifts. It took him nearly 2 years to construct and film all of its paths and mechanisms.
3DSage got their hands on this nifty mechanical device from Japan – it’s a hand-operated gadget which follows the outlines of a stack of disks to move its arm, which in turn draws a corresponding image. A web-based conversion tool is used to design disk templates.
A look at the Rudolf Grauer BK-1500 – a machine designed to crank out up to 1500 paper clips per minute in a variety of shapes by bending stiff strands of wire. The voiceover is in German, but that just makes the engineering seem even more serious and impressive.
We always assumed that LEGO constructions were fairly delicate, and certainly not capable of lifting more weight than we can. But the Brick Experiment Channel shows off a contraption they built that can lift 102.2 kg, or about 224.8 lb, using only LEGO Technic parts and string.
JohnnyQ90 shows off a sweet miniature gas-powered stirling engine. It’s powerful enough to spin a propellor to nearly 2,000 RPM, so keep your fingers away. While Johnny made the turbine fan, he’s quick to point out that you can buy the engine itself from Banggood.
Telegraphs were once the fastest way to send messages over a distance. While they’re long since obsolete, DIYprojects decided to build a modern take on the paper strip telegraph, using an Arduino Mini, a motor, wood, and a pen to write down text messages. Build guide here.
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 (mostly) satisfying video which shows how a Heller 5-axis milling machine carves away at a solid block of metal, transforming it into a spherical shape, first starting with rough lines, and gradually refining it. Though we really need some closure after they left it with a flat top.
Next time you go to the deli and it takes them 5 minutes to slice your meat, ask them to replace their machine with the TEXTOR TS700-UB. This industrial slicer spins up to 2000 rpm, cranking through pepperoni, bacon, and other meats, and neatly stacking them in the process.
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.
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.
Wolf Zipp shows off his working scale model of the SLJ 900/32 Wowjoint, a machine used to transport and place large sections of bridges. it has pneumatic lifts, wheels that can drive in any direction, and a cantilever system for crossing bridge pillars. It’s not fast, but it is impressive.
