Inspired by the nanotech “Iron Spider” suit seen in Spider-Man: No Way Home, JLaservideo wanted to see if he could replicate Spidey’s instantly-appearing, eight-legged outfit. J’s suit hides its appearance beneath a thermochromic pigment, and has inflatable tentacles that unfurl like those party horns.
LEGO machine master Akiyuki shows some fascinating and unusual mechanisms. The designs were inspired by a “mangle rack,” which converts circular motion into rectilinear motion by moving a gear along the outside of a set of pins. He uses the method to smoothly move shapes around a track and to create a clock display.
Wheels are good at maneuvering vehicles over most surfaces, but they’re not always great at climbing irregular or rough obstacles. Engineer James Bruton fabricated these unusual “Pedrail” wheels that use a system of articulated “legs” and “feet” to roll and walk over uneven terrain. They look cool, but are they practical?
Maker Ivan Miranda lives in a beautiful place in Spain. But he hates when it rains there, and he doesn’t like carrying an umbrella. So he set about the task of engineering a motorized helmet that uses a powerful motor and a turbine to blow the rain away from his body. And yes, it works in real rain.
Usually, if you need to get a wheelchair upstairs, you have to take the elevator or a ramp. But at Seattle’s Space Needle they have a special set of stairs that transform into an ADA-compliant wheelchair lift with the push of a button. The retractable lift was engineered by UK outfit Sesame.
Rolls-Royce shared this brief, but fascinating look at the process of building one of its Pearl 15 jet engines at their factory in Germany. Each engine is assembled by hand by a team of skilled mechanics out of thousands of individual components. This particular engine was later attached to a Bombardier Global 6500 business jet.
GazR’s Extreme Brick Machines shows off another unique LEGO Technic vehicle. This tank-like machine features two wedge-shaped body segments connected by a retractable hinge mechanism. This design allows it to crawl easily over a variety of uneven terrain, climb stairs, and even negotiate soft objects like pillows.
Split-flap displays used to be common in everything from tabletop clocks to arrival and departure boards at airports. While not as popular these days, these electro-mechanical displays are still marvels of engineering. Scottbez1 walks us through how they work with a demonstration of his single-digit Arduino-controlled display.
Engineer Matt Ferraro came up with an innovative method to hide images in clear acrylic. At first glance, the tile appears to be completely transparent, but when light passes through it onto a surface, an image is revealed. The technique relies on caustic patterns which cast shadows and transmit light at varying intensities.
We’ve seen Boston Dynamics‘ ATLAS robot evolve over the years to become incredibly agile. Now learn about the technology that makes this impressive humanoid work from the engineers who built him. Like any good science and engineering challenge, failure is part of the learning process.
The Brick Experiment Channel follows up its video of LEGO vehicles climbing over things with a series of more challenging obstacles. The new vehicle design includes a second adjustable joint, which allows it to climb objects and surfaces that look like they should be impossible to traverse.
Heavy-duty cardboard tubes are used to protect rolled goods in transit and provide forms for concrete construction projects. SBS Tube shows off the production process behind these large tubes, which involves gluing together numerous individual strips of brown paper around a metal roller.
Shane from Stuff Made Here has built himself machines to help cheat at baseball, basketball, golf, and pool. His latest engineering feat? A wearable archery-bot which automatically aims and shoots at targets. It even can hit a moving target by predicting where it will be by the time the arrow gets to it.
Building full-size rockets typically requires the creation of costly custom tooling. But Relativity Space is taking a different approach to the problem, using a giant 3D printer and additive manufacturing to melt and form aluminum into the shape of a rocket. Veritasium takes us inside of their facility for a look at how it works.
GMC’s new Hummer EV blends brains, brawn, and batteries into one impressive package. Incredibly, the electric truck and SUV were designed and engineered on a timeline about half that of a typical new vehicle. We went behind the scenes at GM’s Milford Proving Grounds for a look at some of the technology that made this possible.
Setting up dominoes can be time-consuming and requires a steady hand. We’ve seen robots that can stand one domino at a time. Mark Rober and his engineering pals presents DOM – a custom-built robot that can set up 300 dominoes at a time. The robot arm and Hot Wheels track loading system is equally awesome.
If you’ve never seen one, a plasma popper is an awesome-looking device that directs a ball of propane gas through a series of twisted tubes. Charles over at Hacksmith Industries was asked to build a plasma popper, then leveled up the challenge with bigger and bigger versions, culminating with a massive fireball maker.
Aerospace engineer Tom Stanton has a thing for flywheels. Here, he first shows us how to build a flywheel that spins smoothly thanks to magnetic levitation, then how that spinning action can be used to generate a small amount of electricity and capture it via copper induction coils.
If you’ve ever played with a vintage manual typewriter, you know how hard it can be just to hit those mechanical keys with enough force. JBV Creative built a custom robot that uses 3D-printed “fingers” and servo motors to type text and ASCII art on an old Remington Rand Office Riter. Money shot at 15:34.
Motorized wheels aren’t the only way to make a self-propelled skateboard. Integza shows us how he built a 3D-printed water pump to propel a skateboard. After a couple of failed attempts, he was able to get enough water flowing to move the skateboard. It seems to be more effective as a water gun than as a skateboard.
Shane at Stuff Made Here is the engineer behind creations like the haircutting robot and the unmissable basketball hoop. In his past videos, you may have noticed that he has quite the assortment of tools in his shop. To show off his collection, he used each of his machines to make a different kind of ball bearing catapult.
While it’s not as fancy as modern mining conveyors, this vintage ropeway transports shale from a quarry to a brickworks without using electricity or fuel. It uses the weight of materials coming downhill to pull empty buckets uphill. Tom Scott shows off the 100+ year-old system that moves 300 tons of shale per day.
The Ruyi Bridge is one of the most interesting bridge designs on the planet. Located in the Shenxianju Scenic Area in Taizhou, China, it features three connected arches – one that rises and two that dip. The two lower bridges are connected by a glass walkway which allows pedestrians to peer down to the forest 459 feet below.
Ian Davis needed a prosthetic to replace four fingers on his left hand. Rather than purchase a commercial model, he engineered an awesome metal hand that looks like something straight out of The Terminator. It’s capable of opening, closing, splaying its fingers, and makes satisfying sounds as it flexes.
Good airflow is important for keeping electronic components cool, so most computers use fans to circulate air. But we’ve never seen a computer that cools itself by breathing. DIY Perks shows off a gigantic machine he built that quietly pumps air in and out using bellows.
Microsoft asked Hacksmith Industries to help promote the addition of MLB The Show 21 to Xbox Game Pass. So they got to work building a shoulder-mounted pitching machine with the goal of firing balls at pro pitcher speeds. The sound it makes when it revs up is quite terrifying.
