Drones that charge right on the power lines they inspect is a promising concept, but comes with plenty of challenges. The Drone Infrastructure Inspection and Interaction (Diii) Group of the University of South Denmark is tackling these challenges head-on. The gripper for these drones may seem fairly straightforward, but it needs to inductively charge, grip, […]
When it comes to making things that glow, there are two ways to stand out from the crowd. You can make something very big, or something very small. [DIY GUY Chris] has done the latter, producing a tiny LED cube that he says is the world’s smallest. As is so often the way, the build […]
Long before we had internet newsfeeds or Twitter, Ceefax delivered up-to-the-minute news right to your television screen. Launched by the BBC in 1974, Ceefax was the world’s first teletext service, offering millions of viewers a mix of news, sports, weather, and entertainment on demand. Fast forward 50 years, and the iconic service is being honored […]
YouTuber [MechPanda] has recreated a DIY STM hack we covered about ten years ago, updating it to be primarily 3D-printed, using modern electronics, making it much more accessible to many folks. This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants. With individual drive wires attached to […]
When you think 1080p video, you probably don’t think STM32 microcontroller. And yet! [Gabriel Cséfalvay] has pulled off just that through the creative use of on-chip peripherals. Sort of. The build is based around the STM32L4P5—far from the hottest chip in the world. Depending on the exact part you pick, it offers 512 KB or […]
It can often feel like modern devices are less hackable than their thicker and far less integrated predecessors, but perhaps it’s just that our techniques need to catch up. Here’s an outstanding hack that adds a dual SIM slot to a US-sold eSIM iPhone 15/15 Pro, while preserving its exclusive mmwave module. No doubt, making […]
The Raspberry Pi has been around for over a decade now in various forms, and we’ve become plenty familiar with the Pi Pico in the last three years as well. Still, these devices have a great deal of potential if you know where to look. If you wade beyond the official datasheets, you might even […]
[Andre Me] has long-standing interest in automating 3D print jobs, and his latest project is automating build plate changes on the Bambu A1 Mini. Here’s how it works: each build plate gets a sort of “shoe” affixed to it, with which attachments on the printer itself physically interact when loading new plates and removing filled […]
Static electricity often just seems like an everyday annoyance when a wool sweater crackles as you pull it off, or when a doorknob delivers an unexpected zap. Regardless, the phenomenon is much more fascinating and complex than these simple examples suggest. In fact, static electricity is direct observable evidence of the actions of subatomic particles […]
Ever want to build a RP2040 devboard that has everything you could ever want? Bad news, “everything” also means adding 1.8 V GPIO voltage support. The good news is that this write-up by [xenia] explains the process of adding a “3.3 V/1.8 V” slide switch onto your board. Some parts are obvious, like the need […]
