Awesome Diy

The Q shows us how to use plastic soda bottles, tire valves, tubing, and a few other bits to build a homebrew compressed air weapon which can fire a seemingly endless stream of pellets. We’re thinking you could ramp this thing up to include as many soda bottles as you can carry.

Patrick Adair loves to make rings out of uncommon or unusual materials. For his latest project, he waited hours to be one of the first to get an iPhone 8. Then he promptly destroyed it to make an accessory that would be at right at home in The Ninth World.

Bare Conductive’s Electric Paint Kit comes with an LED light, conductive paint and paper templates. It lets you make a touch-sensitive lamp, a motion-sensitive lamp and a dimmable lamp, no tools or computer needed. You can also use the LEDs in more complex projects.

There are lots of cool third-party housings for the Nintendo Switch, including ones that are transparent. But transferring the console’s guts can be disastrous if you’re not careful. Good thing JerryRigEverything made a comprehensive how-to video.

Natural Nerd shows how to build a countertop machine which can dispense multiple beverages. It uses aquarium pumps to move liquids into your cup. It’s best for tea, juice, and other non-carbonated drinks. Full materials list and build details available on Instructables.

Builder Ivan Miranda shows off a unique remote-controlled vehicle he 3D printed that steers entirely by adjusting the direction of its thrust. The field test video demonstrates it’s lack of controllability, but we’re betting it would be fun on a frozen lake or skating rink.

DIY Perks shares his favorite project yet: a handmade Bluetooth speaker. He says its shell is made of concrete, but the only aggregate he used is sand. Nevertheless, his video, templates and list of materials will save makers a lot of time and headaches.

Primitive Technology made bricks and roof tiles out of plain old mud. He made molds out of wood, then dried the bricks in the sun and in a kiln. He realized that he should filter the mud next time, because the sand and gravel resulted in brittle bricks and tiles.

Grid Beams look and work a lot like Meccano girders, except they’re large and sturdy enough to make furniture, structures and other usable objects. They come in either recycled Douglas fir (with 5/16″ holes) or aluminum (with 7/16″ holes). Learn more in the Grid Beam book.

Inventor and builder Colin Furze recently showed us how to build a hot tub on wheels. In part two of the video, he took his water-logged BMW E30 for a spin, and came to realize some of the quirks of driving in a car filled with hundreds of gallons of H2O.

Blackfish shows us how to create a really cool toy weapon which fires rolled up paper projectiles. Its rubber band powered revolver mechanism lets it fire up to eight darts without reloading. We assume you could expand on the idea and make one that fires more ammo.

We’ve seen hot tub boats, but a hot tub car? Only Colin Furze would be brave enough to take this on. As if the plan wasn’t crazy enough, he chose to sacrifice a BMW E30 convertible. Watch him try his best to seal and reinforce the car for its new occupant – a ton of hot water.

Today’s cotton candy is made by heating and spinning sugar using a motor. Eater host Clifford Endo is here to show you how to make it the old fashioned way, using a technique similar to noodles, hand-pulling inverted sugar to make thousands of hair-thin sugar strands.

Toy replicas of Dragon Ball Z‘s iconic Saiyan Scouter are a dime a dozen, but most of them use a headband to stay on your head. Foam lover Odin Abbott used craft materials to make a Scouter that hangs on his ear. The key is to add a piece that’s similar to earphone grips.

All men must trade. Redditor carlotta4th spent hundreds of hours learning the ins and outs of laser cutting to make a beautiful Settlers of Catan board game set with cities and settlements based on the major houses in Game of Thrones.

Most beer koozies are made from foam or fabric. But Ollari’s shows us how to make a super slick koozie from carefully segmented blocks of walnut, maple, and padouk, glued together, then turned on a lathe. A layer of clear lacquer protects it from condensation.

NightHawkInLight shows us how we can make a stove out of a soup can. All you need is a can tapper or can punch to create air vents and feet out of the can’s walls and base. Although in our opinion you should also have a pair of protective gloves.

“Do not begin unless you intend to finish.” Prop maker and restorer Steven Richter made a screen-accurate replica of the Jumanji board game. Skip to 14:38 for the finished build. You can buy the game pieces and cover casting on his Etsy shop.

It may not be the most sonically pleasing instrument, but the engineering behind Josh Sheldon’s build makes up for it. The organ uses 49 stepper motors which spin backwards against variably-sized disks, producing waves of electrical current which can be amplified.

ElectroBOOM’s Mehdi Sadaghdar is mad as hell, and he’s not going to take it anymore. After seeing way too many videos of fake science and “lifehacks,” he decided to do something about it, and debunked a few of the more heinous ones.

Primitive Technology shows us how to make a very simple blower that can easily keep a small furnace going. The blower is made of a stick, a rectangular piece of bark that acts as a rotor, and a length of twine that can be pulled to spin its blade.

Builder John Heisz shows us the steps required to transform a couple of simple blocks of wood into a wonderful decorative knife. It might not be a practical tool, but it sure looks pretty. Want to give it a try yourself? Grab the template here. A parts kit is also available.

Redditor barryabrams figured out a way to accurately replicate Mars’ rusted red color: with actual rust. He sprayed sheet metal with hydrogen peroxide to instantly induce oxidation. Then he screen printed Mars’ topography in black over the rust.
