We’ve seen toy weapons made from Coca-Cola cans, but this build from The S (not to be confused with The Q) is designed to launch the aluminum soda cans. The spinning cardboard and PVC gatling gun rapidly fires off eight Coke cans in just a couple of seconds.
It might look a bit like the Starship Enterprise, but what you’re actually looking at here is a rubber band machine gun that uses a pan-type magazine. While builder parabellum1262 hasn’t provided plans for building one, he does have tutorials for many other cool rubber band guns.
Using cardboard for its shell, and popsicle sticks and R/C car parts for its drivetrain, V. Idea created a miniature utility truck with spinning brushes that sweep up lightweight objects from the sidewalk in front of it. Hot glue is a wonderful thing, isn’t it?
Latheman’s crazy machines made what he calls the “impossible screw.” If you hold it sideways, it will turn only clockwise. It doesn’t matter if you flip it. The only way to get it to turn both ways is to hold it upright. It’s a fun trinket that you can replicate with a hacksaw and a file.
Relics? No, they’re newly made cups. How to Make Everything tried to make biologically-sourced plastic using milk, potatoes and sugar. He actually succeeded in making plastic out of all three ingredients. But molding them was another matter. At least they’re biodegradable.
The Hexbot is a modular, quiet and accurate robot arm that can perform a variety of tasks. By default, it comes with a pen holder that lets it write and draw. But you can also get modules that turn it into a laser engraver, 3D printer and even a pick-and-place machine.
Pimoroni’s Picade Console Kit is the screen-less version of its Picade Desktop Arcade Kit. It comes with the same joysticks, buttons and Picade X HAT as the desktop arcade kit. All you need to add is a Raspberry Pi, a power supply, a microSD card and an HDMI cable.
Instructables contributor Mikeasaurus shows off his ridiculously dangerous looking creation, a skateboard which leaves a fiery trail in its wake. It drips out a small amount of fuel triggered by a foot-controlled switch, and ignites it with an electric sparker. Full build log here.
BrainfooTV shows us how to make nifty little rockets using ordinary household items like aluminum foil and strike-anywhere matches. They fire as far as 60 feet, and are surprisingly stable and accurate. The tailfins aren’t required, but they do make them look cooler.
How to Make Everything decided to how many U.S. one cent coins it would take to make a copper sword. He first had to separate older and newer pennies to get the ones that are mostly copper, then set about the task. We’d love to see the blade patina over time.
