This compact desktop laser can cut wood, acrylic, leather, and other textiles, and the 10-watt model can engrave just about anything, including glass and aluminum, and cut through 5mm wood in a single pass. Its bed is large enough for objects up to 8.26″ x 7.48″, and an optional roller allows for engraving cylindrical objects.
We’ve seen how factories make full-size chain-link fencing by bending and twisting stiff wire. Now watch how it’s done on a much smaller scale. W&M Levsha created this custom machine that bends copper wire into the proper angles to make a mini fence. The weaving still needs to be done by hand though.
We’ve previously taken a behind-the-scenes tour of a bowling alley. This video from 3D animator Jared Owen offers a more in-depth explanation of the engineering and mechanics that go into the machine that magically straightens and resets the pins between balls.
Geoffroy de Crécy’s haunting short film is composed of a sequence of vignettes, each capturing a stark and lonely place, devoid of life other than humanity’s mechanical inventions. The subtext, of course, is what happened to all of the people, and where did they go? Mass alien abduction? Spontaneous combustion?
Normally, if you want a mural on your wall, you need to paint it. But the guys at Russia’s Cool Print SPB have a computer-controlled rig that does all the hard work. The machine rides on rails and then moves along the wall like a gigantic inkjet printer, outputting large-scale, full-color images. Longer tracks = wider images.
We’ve previously seen a LEGO machine that could neatly distribute and space wooden dominoes. But this one works a bit differently. JK Brickworks‘ machine carries stacks of LEGO bricks in a cartridge then dispenses them to form perfect lines of dominoes. Its drivetrain allows it to be driven in straight lines or curves.
Created by Tentacle Media Ltd., the Mini-Mutoscope is a 3D-printed replica of a 19th-century mechanical flipbook. The display works like an animation flipbook, only its movements are smoothly controlled by a crank. It holds up to 42 squares that you can load with your own animations, or one of the samples provided by Tentacle.
Think of how strong a steel chain can be. Then imagine the forces that must be necessary to shape and connect its links. In this video from Engineering and Architecture, we get an up-close look at a specialized machine that takes lengths of steel wire, then scores, cuts, bends, and presses the pieces together.
For a motor to work, it needs tightly-wound copper or aluminum coils to generate a magnetic field when current is applied. This fascinating video from NIDE shows how their machines do the work automatically, first loading an armature, then rapidly winding copper wire around its fins.
Saarland University researcher Marc Teyssier created the creepiest webcam we’ve ever seen. The Eyecam uses six servo motors to realistically replicate the movements of a human eyeball, eyelids, and eyebrow, staring down its subject and making sure they are paying attention during Zoom calls.
Using parts from a 3D printer, custom laser-cut components, and LED lighting RCLifeOn created this mechanical table that uses a magnet and a ball bearing to draw complex patterns in sand, only to erase everything it doodles. On the plus side, as soon as it wipes out an image, it gets to work on another.
Mechanical engineer Kuroki Yuto and his collaborators came up with a novel use for a 3D printer mechanism – using the 3-axis machine to manipulate and assemble parts. In this video, they show how the system can be used to put together a sandwich. They used the same technique to assemble a toy car and to fold a shirt.
Try to balance a bowling ball on a circular object, and you’ll almost certainly fail. But engineer Stepan Ozana shows how it’s possible to do just that with a machine. It uses a principle called LQR and REXYGEN control software to monitor the ball’s position and to rapidly move the wheel back and forth to keep the ball from falling.
Aviation enthusiast Viktor built a custom machine that can make identical copies of paramotor propellers. Area28 shared this video that shows how it works by the form of the original, much like one of those machines they use to copy keys. Skip to 6:10 for the money shot.
How It’s Made takes us inside the factory for WEGA, makers of high-end commercial espresso machines. There, industrial machines transform sheets of steel into parts, then skilled workers assemble dozens of components, including a large copper and brass boiler that sits at the center of each machine.
A useless machine is a contraption that’s designed to automatically flip its own switch off as soon as you flip it on. Fornax built a pair of 8-switch useless machines, then linked them up to flip each other’s switches, resulting in a perpetual battle for switch-flipping supremacy.
Skynet, er Boston Dynamics reveals another of our future robotic overlords. Stretch is a wheeled robot that uses an articulated arm and suction grabber to pick up and carry objects, reducing repetitive and back-breaking work for humans. Watch it pick up a Spot robot, then set up and operate a box handling line.
Is your finger flick underpowered? Worry no longer! Thanks to The Q, there’s now a solution for weak finger flickers. The maker designed and fabricated a metal cover that gives his middle finger an extra boost of power thanks to a spring-loaded mechanism. This must be killer for paper football games.
A while back, expert LEGO engineer and mathematician Alexander Holroyd created a 7-segment display that uses LEGO Technic parts to change digits. Fello LEGO fan and GBC builder Fernando recreated the intriguing machine, and shared video footage of his version in action.
It’s pretty tricky to balance a cube on one of its corners or edges. But ReM-RC shows off a really cool machine they built that does just that automatically. The system uses an ESP32 controller, an MPU-6050 gyroscope-accelerometer chip, and a set of three servo motors that spin wheels to maintain its balance.
