Stefano Rossi

Hi, I’m Stefano.

I study electronic engineering in Brescia, Italy. I’m a radio amateur and I volunteer on radio communications for Civil Protection. I build things with radio, electronics and servers.

Things I’ve built

Some for work, many for someone who needed them, all of them to learn something. Each project has its own story, with photos of how it went.

Monte Ucia

On the mast of the radio station at the top of the mountain, Ernesto, Alberto and I put up two solar-powered repeaters for mesh radio networks. They cover a good part of the Po Valley.

EnjoyBuds

A radio network for finding people where phones have no signal. I co-founded it, and I built the device software, the repeaters, the servers and the app.

since 2024

LoRa Brescia

A video about sending messages without the internet turned into a group of nearly a thousand people building LoRa radio networks: guides, an evening at the club and lots of new repeaters.

About me

I’m easily moved and I love meeting people: at radio meetups, at fairs, on top of a mountain, anywhere there’s someone with a radio in hand and a story to tell.

Every one of my projects has taught me something. I like understanding how things work all the way down, and then making them work for real, outside, in the cold and the rain.

If you meet me at a radio meetup, I’ve probably got a radio in my pocket and an antenna in my backpack. I’m open to collaborations, projects and work.

What I can do

Radio

I design mesh radio networks: coverage, antennas, how much airtime every message takes. I hold an amateur radio licence and I measure what I install.

Electronics

Firmware for nRF52840 and ESP32 microcontrollers, prototypes with Arduino and Raspberry Pi, basic circuit boards, electrical wiring and home automation.

Servers and software

I put services into production on Linux and keep them running, with Docker, databases and MQTT. I write and review code, with help from AI too.
