Looking for insipiration
In the last 4 years I've been working at an automation company that builds systems, machines and most importantly plants based on a Modbus RTU communication protocol, and distributing data to the IO devices (such as digital IO, drives, thermoregulators and so on) in a BUS topology. In particular, our preferred physical (OSI electrical) layer is almost always the 2-wire RS485. Read More Modbus RTU…
In December 2024, I decided to make an electronic toy for my 2 years old nephew - one that could combine colors, music and sound. Read More Color Player
Recently I needed a portable, albeit simple, digital oscilloscope. I started searching the web for projects already developed that would yield the result I had in mind: a couple of MHz sampling rate (and a few hundred kHz bandwidth), a good display, simple to construct and most importantly cheap. After all, I already have a full-fledged DSO, but it's not portable. Read More My take on Scoppy…
Have you ever needed a way to amplify the sound coming from a computer or smartphone, where the author of the content thought you had the hearing powers of an animal? Or did you ever wish you could immediately mute a signal, maybe whilst preparing the power amplifier or just because you wanted to temporarily listen Read More A very helpful Audio-box
Whenever I'm not alone on a hike, I'd like to be confident that the path I'm planning to travel by has been taken by someone else before me; not only that Read More A tool to download OSM GPX tracks
Why this research? You can probably tell that, if I'm writing this article, it's because there's a lack of public information about EPDs on the web, specifically about displaying video animations and gray shades. Read More Research: videos and gray shades on E-Paper Displays
I know what you re thinking: he must be joking. Surely he knows Arduino is not capable of doing Digital Signal Processing. Think again; I m about to show you how to squeeze that juicy performance out of your poor Arduino board, and push it to its limits. I assume you know what DSP is, and how Read More DSP on Arduino?
Have you ever heard the word dithering ?Chances are that, if you re born after the 1990s, you have not. And you may not know that this technology, first introduced in WWII, has been used in countless applications, some of which up to this day. The idea is simple, yet counterintuitive: making things look better by making Read More An image dithering library
This is one of those project that, from the moment they strike through your mind, you know they have a great potential. As I was working on an library, the idea of an animated picture frame came to my mind. And what design could be more suited, than a real-life Harry Potter newspaper (or leaflet) with moving photos? Read More A proper, moving, Harry Potter newspaper IRL!
Frustration. That s all it s about.Not being able to tell the weather somewhat accurately, even if it s literally the next day. The motivationThis project started in May 2020, while fully immersed in quarantine here in Italy (so you can tell I had a lot of time on my hands ); the frustration about the unreliability Read More One Weather App to rule em all
