Prima Power shows off the power and speed of one of its impressive fiber lasers. Their 6kW Laser Genius slices through sheet metal of varying thickness like a hot, razor-sharp knife through butter. We can’t believe how easily it got through that metal at 1:20. More laser porn here.
THE BEST Machines
It’s been a while since we took a proper vacation – especially one on a beach with fruity pineapple and rum drinks, sunshine, and a cool breeze. Perhaps if we had a vacation simulator Rube Goldberg machine like the one that Sprice cooked up, we’d be in a more cheerful and relaxed mood.
Traditional conveyor belts can move items along a single axis. But Cellumation’s unique system can shuffle items around in any direction. It uses a series of hexagonal modules, each of which has three sets of wheels. Its controller and software can then be programmed to grab and arrange a payload in any pattern.
LEGO Technics expert The Brick Wall is back with another impressive build. This time he arranged a series of multiple machines, which work in sequence to pave a brick road for other LEGO vehicles to drive on. It even lays a gravel foundation and smooths it before neatly placing the bricks.
Making drones out of lightweight materials is a must if you want them to fly. But Motores Patelo went the opposite direction, and created a flightless drone out of metal. Sadly, he couldn’t record the whole build due to the lockdown, but the finished piece is still amazing… and could easily take off a finger.
Jared Owen always does a great job explaining how things work by creating 3D animations of their inner workings. This time, he walks us through the caterpillar-tracked M1A2 Abrams tank, which weighs in at an incredible 68 tons, and can cross just about any terrain. We had no idea these things were powered by jet fuel.
Only like the marshmallows from Lucky Charms? Well you could buy a bag without the oat bits, or you could do what these guys from Google did, and build a machine that separates them for you. The Teachable Sorter can actually be used to recognize and sort other objects, and you can get the code, 3D files, and build details here.
Normally, if you want to blow big bubbles, you need to dip a bubble wand in a pool of soap bubbles. But designer pojken shows off a fun and easy gizmo that uses a pressurized garden sprayer, a wand, and a string frame to continuously feed giant bubbles on demand. Learn to build your own on Instructables.
Today’s computers are largely solid state devices, but some of the earliest examples of computers were mechanical. In this clip, you’ll get an up-close look at Charles Babbage’s 2.6-ton metal computer, a machine its 19th century inventor never got to see, but was eventually replicated in 1991 to prove that it works.
Maker W&M walks us through the process of turning a couple of muffin tins into a miniature concrete mixer, complete with a motorized stirrer. Though in this case, its purpose is to smoothly blend instant coffee with water. It probably would make a good hot cocoa too.
If you’ve ever had a CT (or “CAT”) scan of your body, you know that it makes quite the whirring sound as you slide into its donut-shaped opening. This video captured by a radiographer in Denmark shows just how quickly the machine’s guts spin around as its X-ray beams capture numerous images of your insides.
If you’ve ever had to strip a piece of coaxial cable or other multi-layered wire, you know how difficult it can be to get things just right. The Nitronic ST730T is way more precise than hand tools. Simply key in the wire thickness and the exact lengths you want each layer stripped to, insert a cable, and it works its magic.
Make It Extreme likes to build all kinds of crazy machines and vehicles, and their latest is pretty awesome. Imagine a motorized wheelchair that drives like a tank, and you’ll have a pretty good idea of what you’re about to see. For more detail, check out the tank tread and transmission build videos.
After building a LEGO Technic-powered machine that cranks out yummy tapas, The Brick Wall an even more whimsical assembly line. This machine not only produces toy cars, but makes them out of carrots and cucumbers so you can eat them after you play with your food.
Bantam Tools‘ CNC milling machine makes it easier than ever to create prototypes right on your desktop. It works quickly and automatically adjusts based on material location and tool length. It can mill a variety of materials including aluminum, brass, steel, copper, wood, and more, with a working volume of 7″ x 9″ x 3.5″.
Donn DIY and his family used to cut, split, and stack all of their firewood by hand. As necessity is the mother of invention, he built a series of rigs which help automate much of the process, making it faster and more efficient, with much less back-breaking work. You check out all of the detailed build videos here.
It’s always fun to watch stuff tossed into an industrial shredder. In this clip by Gojzer, they load up a machine with all kinds of satisfying stuff, including ping pong balls, squeaky toys, light bulbs, and popcorn, and gooey blocks of gelatin. Those Coke bottles weren’t going down without a fight.
As long as we’re not carrying a heavy suitcase, we generally take the stairs when given a choice. But for those times when you feel like giving your legs a break, the escalator is quite the invention. Jared Owen provides an animated explanation of the inner workings of this engineering marvel that dates back to the mid-19th century.
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.
The guys from the Beyond the Press channel take a moment away from destroying stuff to show us how something is made. Starting out with a 10-ton steel wheel, Finland’s ATA Gears used their DMG MORI CNC milling machine to gradually whittle its way around its edge to create the grooves in a massive gear.
Inspired by Leonardo da Vinci’s Robot Knight – an automaton he created somewhere around 1495, Robotime’s drawing machines use a series of stackable wood cams to create different sketches as you turn their hand cranks. Available in The Gambler, The Slayer, and The Robot designs. Assembly required.
Artist Daniel de Bruin is an expert at making metal tracks for marble machines. He’s taught us how to make our own, and even made a room-sized marble track. Now, he’s downsized his efforts, creating the tiniest marble course we’ve ever seen, using a custom drive mechanism, 0.6mm wire, and a 5mm wide ball bearing.
After building himself an huge 3D printer from scratch, Ivan Miranda thought he could do even better. The new version features a more reliable, and lighter weight bed mechanism, and greater rigidity for the carriage and printer base. The goal is cleaner and more reliable oversize prints, and a machine that’s easier to work with.
Jason Allemann of JK Brickworks shows off another one of his impressive LEGO kinetic sculptures. This one features a duo of dolphins, each bobbing gracefully in and out of a deep blue ocean. You can grab the parts list and buy the build instructions on Rebrickable.
Art of Engineering explains how the tall construction cranes used to build skyscrapers are able to increase their own height. The process, known as “climbing” a tower crane requires precision and patience, and can be incredibly dangerous if not done properly.
