It is no secret that visual impairments — even those that don’t result in complete blindness — make it very difficult for people to live their lives. White canes can help people get around, but they require physical contact. Seeing eye dogs provide very valuable assistance, but they’re expensive and need care of their own. […]
In our last annual report we described 2021 as one of the busiest and most productive years in Arduino history in terms of open source development (if you missed that report, go read it now as it contains so many nice things). Well, we didn’t rest in 2022 either! The Arduino team has been busy […]
Released in 2015, the Apple Pencil is a technology-packed stylus that allows users to write on iPad screens with variations in pressure and angle — all while communicating with very low latencies. Nekhil Ravi and Shebin Jose Jacob of Coders Café were inspired by this piece of handheld tech to come up with their own pencil concept, except […]
Most modern digital cameras are perfectly capable of capturing photos of the stars. But many of them have trouble collecting the small amount of light available in a short amount of time, which means that you need to leave the shutter open for 30 seconds or more to get a decent exposure. That presents a […]
If you’re ever tried to capture some macro photographs (very close-up pictures), you’ve probably noticed that it is difficult to get proper focus. Because the depth-of-field (DoF) for macro lenses is so small, you can only keep a narrow range of distance in focus at any given time — everything else is blurry. One solution […]
While the typical computer user doesn’t need to worry about it, those of us who overclock our computers or run them hard like to know how they’re performing. If, for example, you overclock your CPU, then you probably want to keep an eye on its temperature to ensure that it doesn’t exceed a safe level. […]
Conventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a battery, boost converter, […]
The whole purpose of machine automation is to eliminate human needs and errors. A CNC machine doesn’t get tired, doesn’t need breaks, and performs a task exactly the same way every time. But what if that weren’t true? What if machines experienced human emotions and let it affect their work like we do? That’s the […]
In order to build wearables that react to motion, most people tend to reach for accelerometers, gyroscopes, and flex sensors. But due to their higher cost, teacher Gord Payne wanted to create a low-cost alternative that could be easily sourced and integrated into projects — like that of his student who had designed a hand sculpture and […]
For people not familiar with American Sign Language (ASL), being able to recognize what certain hand motions and positions mean is a nearly impossible task. To make this process easier, Hackster.io user ayooluwa98 came up with the idea to integrate various motion, resistive, and touch sensors into a single glove that could convert these signals into understandable text and […]
