3D Printed Material Might Replace Kevlar

Prior to 1970, bulletproof vests were pretty iffy, with a history extending as far as the 1500s when there were attempts to make metal armor that was bulletproof. By the 20th century there was ballistic nylon, but it took kevlar to produce garments with real protection against projectile impact. Now a 3D printed nanomaterial might replace kevlar.

A group of scientists have published a paper that interconnected tetrakaidecahedrons made up of carbon struts that are arranged via two-photon lithography.

A Minecraft player is building the entire Zelda: Breath of the Wild map

Minecraft and The Legend of Zelda: Breath of the Wild are two great tastes, but do they taste great together? One Minecraft player is making an argument for ‘yes’ with a massive project to rebuild the entire map from Nintendo’s modern classic as a playable Minecraft survival map. It’s still in progress, but the results are already impressive.

PactoTech’s Impressive Arcade Cabinet Has No Fewer Than Six Arduino Boards Inside

Designed for emulating a range of arcade and console games — and playing PC games natively — this hefty build impresses.

Pseudonymous maker “PactoTech” has shown off an impressive four-player arcade cabinet build that uses not one but a total of six Arduino boards for handling various features.

Designed for emulating a range of classic arcade and console games, PactoTech’s build Super Smash Bros. Ultimate-themed arcade cabinet features four player control via arcade sticks and illuminated colour-coded buttons, a single trackball, and more traditional gamepad controllers — plus a wireless keyboard and mouse, handily accessible on a storage shelf above the main controls and below the screen.

Ike T. Sanglay Jr. Puts Apple’s macOS Big Sur on a Custom Handheld, Powered by a LattePanda Alpha

This handheld hackintosh uses an off-the-shelf SBC, some software tricks, and a 3D-printed chassis with Arduino-driven cooling system.

Maker Ike T. Sanglay Jr. has shown off what he believes to be the world’s first handheld computer capable of running Apple’s macOS 11 “Big Sur” operating system — courtesy of a LattePanda Alpha single-board computer in a 3D-printed housing.

“As for how I installed macOS,” Sanglay explains in his video walk-through of the project, “I just followed the OpenCore Dortania guide. The LattePanda Alpha has an Intel [Core] m3-8100Y CPU and 8 gigabytes of RAM.”

Gorgeous Specimen is the Final Word in Clocks

At this point, it’s safe to say that word clocks aren’t quite as exciting as they once were. We’ve seen versions that boil the concept down to what amounts to a parts bin build, which for better or for worse, takes a lot of the magic out of it. You just get an array of LEDs, put some letters in front of it, write some code, and you’re done.

But then [Mark Sidell] sent in his build, and we remembered why we collectively fell in love with these clocks in the first place. It wasn’t the end result that captivated us, although the final clock is indeed gorgeous, but the story of its painstaking design and construction. The documentation created for this project is unquestionably some of the best we’ve seen in a very long time, and whether or not you have any desire to build a word clock of your own, you won’t regret sitting down and reading through it.

This Wearable Cyberdeck Is as Stylish as They Come

Cyberdecks are a dime a dozen these days, but this wearable cyberdeck called Кибердек RA01 that stands out.

The cyberdecks from William Gibson’s novels are pure function. Deckers in that world cobble their cyberdecks together without any concern for style. But that is, of course, punk rock as hell and stylish in its own apathetic way. Today’s cyberdeck community leans heavily into the cyberpunk aesthetic. Very few people build cyberdecks for practical purposes — they’d use a laptop if practicality was their concern. And that is why the hobby is enjoyable, because it gives enthusiasts the opportunity to express their inner dystopian industrial designer. R▲, a Russian “underground cyberpunk artist,” took that to heart when they built this wearable cyberdeck called КибердекRA01.

An ESP32 Controls This Cylindrical OLED Display

YouTuber maker.moekoe built this ESP32-controlled “circular” display using eight OLED screens.

The vast majority of displays have a rectangular 16:9 aspect ratio, or 4:3 for older TVs and monitors. But we’re starting to see more unusual aspect ratios and even screen shapes become more common. Some newer smartphones have ultra-widescreen aspect ratios and round displays are the norm for smartwatches. A square may be the most efficient form, because it doesn’t waste any rows or columns in the matrix, but people like more unique shapes. YouTuber maker.moekoe took that idea to the extreme when they built this ESP32-controlled cylindrical screen.

The Raspberry Pi Pico-Powered Pico MIDI (H)Arp Turns Nearby Wireless Signals Into Music to Your Ears

Driven by MicroPython on a Raspberry Pi Pico with Pimoroni Pico Wireless add-on, this music generator plucks Wi-Fi signals from the air.

Pseudonymous electronics and music enthusiast Kevin, of Simple DIY Electronic Music Projects, has shown off a Raspberry Pi Pico-powered MIDI project with a difference: It generates music based on nearby Wi-Fi signals.

The project was inspired by a 2015 device dubbed the MIDI Arp, which used an Arduino Nano board and a Microchip ENC28J60 Ethernet shield to turn address resolution protocol (ARP) requests into music — played through a Roland MT-32 synth module.
