The old adage that you’ll make a fortune by developing a better mouse trap is not super realistic, as the engineers behind Sony’s Betamax video tape standard could tell you. However, you can still learn a lot building your own, as this project from [ROBO HUB] demonstrates. The trap is intended to catch mice in a […]

Arduino has unveiled a strategic alliance with Amazon Web Services (AWS), a partnership aimed at bolstering its edge hardware and cloud services. This collaboration is set to offer an expanded range of options for Arduino products and Arduino Cloud customers, enabling them to seamlessly integrate AWS into their Internet of Things (IoT) projects. Since its

If there’s something more tedious than winding coils, we’re not sure what it is — possibly rolling and wrapping coins; that’s really a bother. But luckily, just like there are mechanical ways to count coins, there are tools to make coil production a little less of a chore, but perhaps none that have as much
ALL-MECHANICAL COIL WINDER IS A SCRAP-BIN DELIGHT Continue Reading
If you are searching for a quick yet fantastic little project to keep you busy you might be interested in this fantastic Arduino Nano ESP32 based color handheld console created by the Volos Projects YouTube channel. The tiny handheld console features a round display and is powered by an Arduino Nano ESP32. Volos Projects, a

To keep track of a location in a two-dimensional space, two measurements are needed. Most of the time, we would naturally think to do this by the Cartesian method, measuring position along one axis and then again along a second axis. But this isn’t the only way of keeping track of position. Polar coordinates, where

Guitarists will do just about anything to get just the right sound out of their setup, including purposely introducing all manner of distortion into the signal. It seems counter-intuitive, but it works, at least when it’s done right. But what exactly is going on with the signal? And is there a way to simulate it?

In the world of drones and hobby rockets, Niklas Bommersbach is making waves with his innovative safety system. Bommersbach has designed a system that detects critical flight behavior in drones, rockets and other aerial vehicles, activating a two-stage parachute deployment for a safe and controlled descent. At the heart of the system is an Arduino Nano microcontroller that monitors
Awesome parachute system saves drones and rockets Continue Reading
We’ll take a wild guess and say that right now, within arm’s length of wherever you’re reading this, there’s something that was produced by injection molding. Look around; it’s there someplace, and whatever it is, thousands or perhaps millions of other identical artifacts were produced along with it, all by squeezing hot plastic into intricately

Low-power radios, often referred to in the amateur radio community as QRP radios, have experienced a resurgence in popularity lately. Blame it on certain parts of the hobby become more popular, like Parks on the Air (POTA) or Summits on the Air (SOTA). These are events where a radio operator operates off-grid at remote parks
OFF-GRID RADIO ALSO REPAIRABLE OFF-GRID Continue Reading
There are many possible answers to the question of what the lowest-powered hardware on which Linux could run might be, but it’s usually a pre-requisite for a Linux-capable platform to have a memory management unit, or MMU. That’s not the whole story though, because there are microcontroller-focused variants of the kernel which don’t require an
