Maker Laura Kampf teamed up with her friend Patrick, whose audio expertise helped her build an earthshaking sound system for the back of her 3-wheeler. The battery-powered audio system has six full-range speakers and a giant subwoofer. She should have named it “Boomtrike” though.
THE BEST Diy
We’ve seen some pretty great backyard roller coasters over the years, but this is the first time we’ve seen one built in a school gymnasium. We can’t believe that the school would have signed off on this rickety looking construction made from plywood, 2x4s, desks, and chairs though.
Korg’s recently launched Nu:Tekt line will create DIY instruments, effects, and utilities for electronic musicians. First up is the NTS-1 a tiny, build-it-yourself polyphonic synthesizer with a digital oscillator inspired by the prologue and minilogue xd. Sound demo here.
Matthew Davis’ Arcus is a 3D-printable rubber band gatling gun. Its unorthodox appearance is more than just for show. Unlike most rubber band guns, the Arcus uses the energy from the rubber bands being shot out to rotate the barrels and continue the barrage. Grab the 3D models and directions on Instructables.
A while back, Tom Stanton built a cool working trebuchet, but even though it was much smaller than the ones used in battle, it still wasn’t exactly portable. So, Tom set about building a pint-size version that can be used like a slingshot. We’re thinking it would be perfect for flinging wadded up paper at officemates.
Flat-pack model makers Ugears offers this very cool kit that lets you build a mechanical monowheel that actually drives. It has retractable training wheels, but can roll without them on smooth surfaces. With 300 parts, it looks like a challenging 3-hour build. No glue required.
A fun DIY kit for musicians, electronics hobbyists, and just about anyone who likes cool gadgets. The Rhythmo Beatbox lets you build a MIDI controller and drum machine in a cardboard box. It’s got arcade-style buttons, built-in sounds, a battery, and speakers. Its companion mobile app enables sound customization.
Known for their in-depth automotive repair manuals, Haynes is now making a series of kits which let you build your own rudimentary gadgets, including a retro LED handheld game, an analog synthesizer, a working amplifier, a film camera, an FM radio, and a Simon-esque memory game.
Will from London is like the calm version of Colin Furze, creating his own dangerous and over-the-top contraptions in his UK backyard, but minus the shouting. In this clip, he shows off a wood and PVC roller coaster that uses compressed air to produce 1200 lb. of thrust, and accelerating its sled at up to 4.2G. Build video here.
Ollari’s shows us how to take slats of wood from a rickety old door and pallets to create a nifty new piece of outdoor furniture. If you put your mind to it, it’s amazing what you can achieve with a saw, some screws, and glue. We dig the burnt look of the finished piece.
The Hamster Miniature Studio 2 aka “HMS2” specializes in making really tiny objects. Recently they decided to try their hand at crafting a pair of eyeglasses. They have see-through lenses, and are hinged so they can fold. If our action figures ever have a vision problem, we know where to turn.
Jackman Works loves to make things by recycling old wooden shipping pallets. In this video, he takes a bunch of the beat up old wood, slices it into sheets, laminates them, and trims them into some sweet looking, street-style skateboards. It’s interesting to see how he shapes the wood with the vacuum bag.
After making bowls out of a variety of materials, Peter Brown’s viewers have been asking him to make a cereal bowl made of cereal. He finally gave in to their requests. The process is simple, but it takes a lot of time and skill. The end result is beautiful, but it’s questionable if it’s food-safe.
Maker Ivan Miranda’s decided to see if he could modify a remote-controlled car so it can drive upside-down on the ceiling. He added a pair of powerful fans to create downforce (or is it upforce?) It took some trial and error, but he ultimately got it to work. Of course, he could have just bought one of these.
Woodworker Matt Jordan shares an immensely satisfying woodturning video, in which he transforms a lumpy hunk of apple tree trunk into a beautiful work of functional art – though the final piece wasn’t exactly what he planned to make. The fillers are a mix of blue mica dust and ground coffee.
The Q has built some pretty nifty mechanical contraptions from cardboard, and here’s another. Watch as he turns a mix of cardbaord, paper, rubber bands, springs, and popsicle sticks into a working model of a 7-segment numeric display, like you might find on alarm clock.
If you’re not too much a stickler for preserving your vinyl, there are lots of cheap turntable options. But if you REALLY don’t want to spend the money, and REALLY don’t care about your records, you could build one like the one Turnah81 made, using a cordless drill, a coffee cup, and a pushpin as a stylus.
