Last year, we’ve featured a super cheap smart ring – BLE, accelerometer, heart sensor, and a battery, all in a tiny package that fits on your finger. Back when we covered it, we expected either reverse-engineering of stock firmware, or development of a custom firmware outright. Now, you might be overjoyed to learn that [Wesley […]
In the near future, imagine a world where your health is continuously monitored, not through bulky devices but through an invisible graphene tattoo. Developed at the University of Massachusetts Amherst, these tattoos could soon detect a range of health metrics, including blood pressure, stress levels, and even biomarkers of diseases like diabetes. This technology, though […]
We’ve seen a lot of interest in Meshtastic, the license-free mesh network for small amounts of data over the airwaves. [Ham Radio Rookie] was disappointed with his Meshtastic node’s small and inefficient antennas. So he decided to make what we suspect is the world’s first Meshtastic necktie. We assume the power is low enough that […]
We’ve all been there. That sad day when the zipper on our favorite hoodie, bag, or pair of pants breaks in some seemingly irreparable way. But there is hope, and [Magic Stitches] is gonna show you how to make some common repairs using household items and, in some cases, just a little bit of easy […]
If you’re like most makers, you have a few product ideas kicking about, but you may not have made it all the way to production of those things. If you’re thinking about making the leap, [Simone Giertz] recently discussed all the perils and pitfalls of the process from idea to reality. The TLDR is that […]
What’s the only thing cooler than building something electronic? That’s right — wearing it proudly for all to see. But maybe you’re not into wearables. Maybe it’s because you’re afraid of sewing, or simply scared that you won’t be able to launder that blinkenshirt you’ve always wanted to make. Well, the undisputed queen of wearables […]
Living with Type 1 diabetes is a numbers game. There’s not a moment in the day free from the burden of tracking your blood glucose concentration, making “What’s your number?” a constant question. Technology can make that question easier to ask and answer, but for T1D patients, especially the kids who the disease so often […]
By and large, our clothes don’t actively move. They’re simple pieces of fabric assembled to sit nicely on our bodies, and little more. [anoukwipprecht] created something a little more technological and confronting, though, with the Robotic Open-Source Scale Dress. Right from the drop, you can see what the dress is all about. It’s an open-shoulder design that […]
Regular roller blades go way back, relying on a number of wheels mounted in a line and relying on regular bearings. [The Q] came up with an altogether more interesting design by handcrafting some tall skates with two hubless wheels apiece. The build eliminates the hard work of creating the shoe part of the skates. […]
The ever-shrinking size of electronics and sensors has allowed wearables to help us quantify more and more about ourselves in smaller and smaller packages, but one major constraint is the size of the battery you can fit inside. What if you could remotely power a wearable device instead? Researchers at Carnegie Mellon University were able […]
