Despite the science that proves that wearing masks can dramatically reduce transmission of COVID-19 and other illnesses, some people are still refusing to wear them. To solve this problem, engineer Allen Pan decided to build a device that can pneumatically launch a mask onto someone else’s face from a distance.
Factorio is an incredible game about building and maintaining huge factories. After years of development and early access testing, v1.0 is here. You’ll mine for resources, figure out how to make your factories more efficient, and fight off enemies hellbent on their destruction. Grab the trial, or buy the full game here.
Artist Love Hultén pays tribute to Martin Molin and his incredible Marble Machine X project with a miniature, battery-powered version of the programmable, mechanical music maker. Since there are no blueprints for the original, Hultén based his model entirely on available video footage.
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.
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.
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.
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.
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.
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.
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.
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.
“My heart is human, my blood is boiling, my brain IBM.” Styx’s 1983 track Mr. Roboto represented the pinnacle of overwrought concept rock. Yet there has yet to be a more appropriate song played by Paweł Zadrożniak’s electromechanical orchestra, the Floppotron and its servo-powered instrumentation.
Remix artist William Maranci did a great job combining the warm and inviting sounds of Wintergatan’s musical marble machine with Gorillaz’ track Feel Good Inc. As its musician and inventor cranks it up, Maranci has to fool with the BPM a bit, but that’s part of the fun.
Joseph’s Machines already got some salt, but he needs some pepper too. With social distancing measures in place, it’s important not to just hand it across the table, especially since it can make you sneeze. With some help from his friend JackofAllSpades98, they came up with a safer method of passing the shaker.
This highly-articulated LEGO Technic robot by Shadow Elenter uses 19 motors to move its wheels, arms, snippers and grippers to defuse, pick up, and dispose of a phony explosive payload. We’re not sure we’d use it for a real bomb threat, but we’re still impressed.
