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
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
[Josh] has a child and what do children like more than stuffing random things into their mouths? Pushing buttons, twiddling knobs, and yanking things of course! So [Josh] did what any self-respecting hacker would do and built his little man a custom cyberdeck. The build follows the usual route of some electronics wedged into a pelican-style

Material testing is important in big industry, where manufacturers must be able to trust the properties of the raw materials they’re using. The rest of us generally take a supplier’s word for it that they’re giving us what we’ve paid for. However, you could always take on material testing yourself with the Universal Tensile Testing Machine

Parol 6 is a 3D-printed six-axis robot arm created by [Petar Crnjak] as a combination of the principles from a few previous projects. Aside from a pneumatic gripper, each axis is driven by a stepper motor, with at least a few of these axes being driven through a metal planetary gearbox for extra precision and torque.

Do you know how you see those cheap telescopes at the department store? The box has beautiful pictures that probably came from the Hubble. What you will see is somewhat different. You have to carefully look at [upir’s] Arduino thermal camera project because it intersperses pictures of what you expect an 8×8 sensor will produce with images
In the realm of renewable energy, a groundbreaking device known as Mysoltrk is a fantastic project powered by Arduino designed to track the sun’s position, optimizing solar panel performance and maximizing energy production. The tracker is robust, cost-effective, and sturdy enough to withstand outdoor conditions, making it an ideal solution for those seeking to harness the power of
