You can pick up a cheap paper shredder for about 20 bucks, but what fun is that when you can build your own? The Q shows off a homebrew shredder that does the trick using sharpened metal discs. It’s missing the safety mechanisms that production shredders offer, so DIY at your own risk.
THE BEST Diy
It’s pretty clear from bitluni’s use of a chainsaw to cut his wood that he’s no carpentry expert, but he does know a thing or two about electronics. Check out the slick Arduino-controlled LED video wall he built in less than 24 hours. The parts list is in the video description on YouTube.
We’ve seen some pretty awesome backyard rollercoaster builds over the years. Now learn about the physics and complexities of building one, courtesy of NightHawkInLight and engineer Paul Gregg, who shows how to create a gravity-powered thrill ride for less than $500. We also recommend checking out Gregg’s books on the subject.
People with visual impairments could soon join in the fun and frustration of solving a Rubik’s Cube. Puzzle fanatic Bondarenkoyt peeled off the stickers of a standard cube, then created textured squares that could be felt with fingertips. To prove that it’s usable, he solved it blindfolded. Now someone should put this into production.
Despite its popularity as a building material, wood is rarely used in the construction of PC cases. Bucking that trend, DIY Perks built a truly unique computer system from wood, with rope trim. We love how he incorporated the air cooling system as a sculptural design element.
Maker of cool stuff Ollari’s shows us how to turn plywood into a sweet modern ceiling lamp which has a shade made from bent slats placed around its circumference. It actually doesn’t look that hard to do yourself with a little time, effort, and the proper tools.
Bob Clagett of I Like to Make Stuff admittedly isn’t a weapon-making expert, but he sure knows his way around a bandsaw. In this clip, he shows us how he used some scraps of hardwood flooring to create a wooden practice katana with some very impressive results.
Graz Makes realized he didn’t have a good pizza cutter, so he created one inspired by one of his favorite groups, The Wu-Tang Clan. He stole an old table saw blade from Jimmy DiResta, and fashioned it it to look like the rap group’s iconic “W” logo. The finished tool ain’t nuthing ta f’ wit. Full build instructions on Instructables.
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.
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.
