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
One day I was randomly looking through car radio systems on a magazine and noticed this strange function called “SVC”, a.k.a. Speed sensitive Volume Control; I immediately thought “why would anyone have such a feature, when they can use the volume knob by hand?”. But, the more I thought about it, the more I figured… Read More Adapting car volume with speed
In this short essay I decided to answer a question I asked myself many times, while doing electronics: when using a LDR (Light Dependent Resistor, a.k.a. Photoresistor) or, for what matters, any other variable resistor, what is the best fixed resistor value with which to accompany it, such that the combination maximizes the output voltage… Read More On variable resistor voltage dividers
