Since butterfly knives are illegal in many places, Miller Knives decided to make something that borrows heavily from the balisong’s design, but is far less dangerous – unless you’re a bottle cap. If you’re a bottle cap, you’re done for.
Prop maker David Guyton made chest armor with a computer fan in front and a LED-lit jet pack at the back. He made it mostly out of steel and MDF, but he says you can use EVA foam instead. You can purchase the template for $5 on his website or his Android app.
Primitive Technology made a reusable facility for producing charcoal. He builta conical wood frame, walled with mud, then burned the wood to harden the mud and make his first batch of charcoal. If only he had someone with whom to trade the charcoal. For like three sheep.
We’ve all seen laser beams which project images using a persistence of vision effect. While the professional gear does it with moving mirrors, Yertle Vert shows off a neat build using 3D-printed cams and a laser pointer to achieve a similar effect. Instructions on Thingiverse.
Agustin Flowalistik made a fully 3D-printed letter board that looks nearly as clean and solid as one made from off-the-shelf materials. He’s sharing his 3D models for free. The set includes four different board sizes; subscribe to his Patreon and you’ll get access to the source files.
“Everything here has at least two purposes.” Architect Zui Ng designed and partially built his own home, intending to make a modern version of the shotgun house. He ended up saving a lot of money while maximizing his environment by carefully considering practically every part.
DIY Perks made an accent light using RGB LEDs and a Selenite crystal. It sounds like a straightforward build, but he custom made most of the electronics. It does involve a few tricks that will come in handy for other projects, and the result is, in his words, “not bad.”
HomeMadeModern made a simple but stylish stone bench. In particular, he used four slabs of bluestone, which is readily available as it’s often used in patios and walkways. He used a circular saw with a diamond blade for cutting and synthetic rubber to hold the slabs together.
A Guy Doing Stuff walks us through the process of building an absolutely stunning handmade canoe in his garage. The body of the boat was made using dozens of thin strips of cedar, bent, glued, and cut along plywood forms. All told, it took eight months to complete the canoe.
This kit lets you build a crude pinball machine using just about anything as obstacles. It includes mechanical flippers, as well as copper contacts which can be used to register scoring when connected to an off-the-shelf microcontroller, using a free smartphone app.
If you’ve ever found how Segways and so-called “hoverboards” stay upright, check out Joop Brokking’s video tutorial, which shows you how to build your own R/C 2-wheeled robot, controlled via Arduino for about $80 total. Full schematics, build details, and code here.
If you ask us, there are already way too many fidget spinners. But if were going to play with one, it would have to be PressTube’s awesome custom build – an oversize brass triple spinner made by melting and molding bullet casings, then quenching them with liquid nitrogen.
