We’ve always been interested in fluidic computers, a technique that uses moving fluids to perform logic operations. Now, Spectrum reports that researchers have developed an electronics-free contact lens that monitors glaucoma and can even help treat it. The lens is made entirely of polymer and features a microfluidic sensor that can monitor eye pressure in […]
Well, this might just be a Hackaday first. Certainly not the circuit sculpture part, nor the wearable aspect, but the glorious combination of the two. Behold [CMoz]’s Fashionably on Task: a Smart Bracelet for Forgetfulness. The name may be long, but the intent is concise: to showcase your top five must-dos for the day. This […]
Walking on grass, it’s easy, no matter the shoe. How about an inclined trail? Some hiking shoes or nice tennis shoes will do the trick. How about climbing a mountain? Now we are gonna need something special. [Magnus Midtbø] is a professional climber with an acute awareness of this fact and has used shoes of […]
Waveshare makes a nifty little ESP32-S3 based smartwatch product, but its firmware is apparently not to everyone’s liking. Specifically, it’s not to [infiniton] a.k.a [Bright_Warning_8406]’s liking, as they rewrote the entire code base in Rust. No_std Rust, to be specific, but perhaps that doesn’t need to be specified when dealing with ESP32. On the Reddit […]
If a zipper breaks, a 3D printer might not be the first tool one reaches for — but it’s more feasible than one might think. [MisterJ]’s zipper slider replacement is the kind of 3D print that used to be the domain of well-tuned printers only, but most hobbyist printers should be able to handle it […]
Keeping a cool head is difficult at the best of times, least of all when it’s summer and merely thinking of touching bare skin to the pavement already gets you a second-degree burn. Unfortunately, it’s not possible to spend all summer in an air-conditioned room, but what if you took said room with you? Introducing […]
[GizmoThrill] shows off a design for an absolutely gorgeous, high-fidelity replica of the main character’s helmet from the video game Satisfactory. But the best part is the technique used to create the visor: just design around a cheap set of full-face “sunglasses” to completely avoid having to mold your own custom faceplate. One of the […]
In a recent article from IEEE Spectrum, [Alfred Poor] asks the question what do consumers really want in smart glasses? And are you finally ready to hang a computer screen on your face? [Alfred] says that since Google Glass was introduced in 2012, smart glasses haven’t yet found their compelling use-case. Apparently it looks like […]
Pagers were once a great way to get a message to someone out in public; they just had to be cool enough to have one. These days, they’re mostly the preserve of doctors and a few other niche operators. [Kyle Tryon] is bringing the beeper back, though, with a custom ESP32-based build. The ESP32 is […]
There are a few very different pathways to building a product, and we gotta applaud the developers taking care to take the open-source path. Today’s highlight is [Mentra], who is releasing an open-source smart glasses OS for their own and others’ devices, letting you develop your smart glasses ideas just once, a single codebase applicable […]
