Have you got the balls for this experiment? You'll need at least 4; a basketball, tennis ball, squash ball and simple rubber ball. With these in hand, Mr. G will show you how to experiment with potential and kinetic energy while launching these suckers nearly into outer space. 3, 2, 1.... blast off!
This video explains the science behind a trebuchet. The trebuchet is a medieval machine designed to throw objects at or into castles. This video explains that the gravitational potential energy stored in the raised counterweight is converted into kinetic energy in the projectile. Trebuchets make excellent science fair projects.
Amazing video of Haruki Nakamura's Gear's Heart. The pieces fit together like a gear, skip to 0:49 in the video to see it in action. Check out Nakamura's site for more of his work. Previously, Make Optimus Prime papercraft.
Reuben Margolin builds large scale kinetic sculptures based off of mechanical waves. Some of his sculptures contain hundreds of pulleys all working in harmony with each other to create sinusoidal waves and their resulting interference patterns. He designs them all on paper and does all of the complicated trigonometric calculations by hand. Everything is mechanical; there are no electronic controllers.
Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy. The concept is simple: Piezoelectricity is the charge that is produced when certain solid materials (commonly ceramic and crystal) in response to mechanical stress. Piezoelectrics have many applications; in speakers, actuators, sensors, even fuses. For more information, click here.
Gambit is one of the coolest X-Men, and his kinetic energy powers are awesomely powerful. If you want to depict them using special effects in a film, this video will show you how to do it using three free pieces of digital editing software:
Smartphones are designed to be used in portrait mode primarily, so smartphone apps are created with that layout in mind. This means that practically every app on your phone is vertically oriented, which, in turn, means that we have to scroll up and down quite a bit.
From time immemorial, human beings seem to be at odds with one another. When these differences become so heated and unresolvable, it eventually erodes into physical violence. This violence has manifested into some of the most horrific exercises in human history, things which every school child is aware of and none of which we have to recount here. Although humans have been cruel and violent for a very long time, the 20th century may have epitomized that behavior. With two World Wars and many,...

Buyers can't wait for their Tesla Model 3 to be delivered. But with no clear arrival date in sight, buyers are starting to get a little antsy waiting to see what the Tesla Model 3 will look like up close. Luckily, Tesla accessories seller EVANNEX partnered with technology firm Kinetic Vision to try and satisfy buyers for a while by creating an app that lets you view an augmented reality Tesla Model 3 that's nearly life sized.
So a little while ago we covered BUD switches, but there's only so much you can show in one tutorial.
MrfixitRick demonstrates the Shake Flashlight Shaker, as it generates electric power out of faucet water pressure. A Tesla CD Turbine is used to convert the kinetic energy of water into rotation. Then, a connecting rod and magnets charges the built-in battery of the shake flashlight.
April Fool's Day, aka National Screw with Your Friends Day, is finally here. You can always pull a conventional prank, like strategically placing a whoopee cushion on your mom's chair, but that joke has been exhausted generations before smartphones were around. We live in a day and age where smack cam is the new level of pranking, so it's time to step your game up, novices.
As many of you know, I have been running a couple of series here on Null Byte about digital forensics called Digital Forensics for the Aspiring Hacker and Digital Forensics Using Kali. Although many readers have seemed to enjoy these series, just as many seem to be pondering, "Why should I study digital forensics?"
As many of you know, I firmly believe that hacking is THE skill of the future. Although the term "hacking" often conjures up the image of a pimple-faced script kiddie in their mother's basement transfixed by a computer screen, the modern image of the hacker in 2015 is that of a professional in a modern, well-lit office, hacking and attempting to development exploits for national security purposes. As the world becomes more and more digitally-dependent and controlled, those that can find their...
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
Will the predicted apocalyptic date — December 21st, 2012 — really be the end of the world? In this ongoing five-part series, we examine what would happen if zombies, nuclear weapons, cyberwars, earthquakes, or aliens actually destroyed our planet — and how you might survive.
Beauty is a fine line between art and science for Pe Lang, a Swiss sculptor living and working in both Berlin and Zurich. The autodidact artist specializes in graceful, hand-built kinetic sculptures made of magnetic, electrical and mechanical devices, all of which are elegant and completely mesmerizing. "Positioning Systems - Falling Objects" is one of his newest contraptions, which feels like a mix of home waterfall fountains, mechanical metronomes and a busy manufacturing plant.
Theo Jansen is really cool. If you dig around in the corkboard here, you can find another video about him. He makes amazing kinetic sculptures from PVC pipe, and has a wonderful artistic point of view. I just discovered this old TEDTalks podcast via Taylor Browning's site. Fantastic stuff, check it out:
3+ minutes of kinetic football cinematography! Enjoy! (The Ivory Coast has a space program...?)
Unfortunately there's no information in English on this Japanese craftsman's incredible mechanical wooden sculptures. His YouTube profile lists his occupation as pharmacist (apparently he's a pharmacist with some crazy woodworking skills).
Dan McPharlin has created some super-sweet retro electronics papercraft models. Click through to Dan's Flickr page to view the entire collection.
So very pointless, yet unquestionably spectacular. The best kind of "art" performs no other function than to delight the viewer, and Japanese YouTube user Denha's complex marble machines do just that. But are marble machines art? You can call them that—or toys, scientific contraptions, engineering feats—but however you choose to label them, the best marble machines are complicated, skillfully crafted, and driven by the principles of potential energy, kinetic energy and gravity.
Robots have a long-standing obsession with tandem bikes. The first song ever sung by a computer? "Daisy Bell." If you don't recognize the title, you might nevertheless recognize the song's famous refrain: "But you'd look sweet/Upon the seat/Of a bicyle built for two." That was 1961. Fast forward nearly forty years and robots aren't merely singing about bicycles built for two, they're riding them. Take Joules, for example:
Alter Evo on Flickr has created this amazing starfighter and service unit vehicle. This is what he says about it:
A small, pointy wooden stick normally used for picking at your teeth after a meal can do many other things. Use the humble toothpick to aid you in microwaving your potatoes, marking the end of clear packing tape, applying glue onto sequins and plugging the hole in your garden hose.
Since today (11/11/11) is the last 6 digit binary date this century, I thought we should look at some kinetic binary calculators.
Kirsten Dunst is turning Japanese in short skirts and thigh highs. The art world crashes Hollywood in this video piece starring Dunst, directed by McG and produced by world renown Japanese artist Takashi Murakami.
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
Dutch artist Theo Jansen creates incredible kinetic, wind powered sculptures, resembling the skeletons of ambiguous beasts.
Korean artist Osang Gwon creates more than just alluring paper-made girls. Gwon has moved past traditional papercraft, taking volumes of photographs of his subjects and constructing sculptural forms from the carefully arranged 2D images. Gwon shows in galleries, and has done commissioned projects for both Fendi and Nike.
