This is a Proof-Of-Concept of an organ keyboard using magnets instead of springs to obtain a nice upward release action and a decent downward counter-pressure when playing.

Designing a musical-instrument keyboard confronted me with some ergonomics considerations and material choices. I did some research on magnets as well, to have a better understanding of their force irradiation and how to select them to save space, weight and achieve the best feeling when playing.

GELOSO

Geloso, founded in 1931 by Giovanni Geloso, was an Italian manufacturer of radios, televisions, amplifiers, amateur radio receivers, audio equipment and electronic components. Its headquarters were situated in Milan, Viale Brenta 29.

In 1931 the company started the production not only of radio sets but also most of the electronic components with which they were built and, over time, also developed and patented many others.

After the Second World War, Geloso expanded and expanded his production, becoming from 1950 onwards, a point of reference for enthusiasts of consumer electronics and hobbyists.

🛠️ Introduction

This blog article gathers a series of DIY radio experiments, ranging from early analog detection with Galena crystal receivers to digitally driven AM transmission via Arduino microcontrollers. Inspired by a love for vintage radio sets and low-power communication techniques, this collection explores both the simplicity of early unpowered detection and the elegance of amplitude modulation (AM) implemented in modern embedded systems. These are primarily short-range (QRP) experiments — ideal for educational settings, hobbyists, and radio tinkerers looking to bridge past and present technologies.

There are many many ways to build an amplifier, depending on money and time available, choosing the most expensive components, creating (or again, buy) a custom metal chassis (or have a friend that can make many as you want) with the objective to obtain a better build for the same price.

Building tube amps is very rewarding, and can keep you busy with its fair amount of metalwork and various power tools, like folding machines, press, lathe, milling machines and uncountable hand tools. Finishing the build with spray paint, adding lettering, logos, design elements one can go on forever. Custom shop!

Proiezione Origami – Book Cover Design

This cover design project began as a collaboration with the Italian author Alessandra Arcieri, who penned a cryptic and futuristic tale titled Proiezione Origami, set in a cyberzen world where consciousness, code, and combat blur into a single stream of unfolding events.

Introduction to the Narrative

“Rome, New York, Bombay. What will be the next target?”

Set in a fragmented future, the narrative explores transcontinental power plays, high-stakes psycho-games, and mythic figures recast in digital landscapes. The protagonist, known as Agent Alpha, must decode a layered conspiracy crafted by a corporate demiurge. Her mission is embedded within verses from Walt Whitman’s I Sing the Body Electric—a haunting reference and anthem for the electrified self.

Over the years, I’ve developed and published a number of mobile apps — primarily for Apple iOS, though I’ve also ventured into Android using Java and Kotlin. This post offers a curated list of those projects that I believe are most worth sharing.

Some of these apps are open source, and I’ve linked to their public repositories where available — feel free to explore, fork, or contribute.

What we now call “apps” began as simple, standalone tools. Here are mine — crafted from scratch, designed with care, and sometimes a bit of eccentric joy.
