Four practical, exercise-driven books on open source, amateur radio, AI prompting, and Git — written for makers who'd rather build something real than read theory.
No. 01 — Open Source
A hands-on guide to taking a side-project idea all the way to a real, maintained open-source repository — designing it, building it, and keeping it alive after the initial excitement fades. Every chapter pairs with a real exercise, building toward a working example project from scratch.
No. 02 — Radio & Electronics
An 18-chapter path through amateur radio for makers: software-defined radio, decoding ADS-B and weather satellites, Morse code by ear and by microcontroller, LoRa link budgets, mesh networking, and studying for your actual radio license.
No. 03 — AI & Prompt Engineering
A practical, exercise-driven book on getting AI models and coding agents to do what you actually mean — output formatting, few-shot examples, decomposition, repo rules, spec-driven work, and the daily habits that make prompting a reliable skill instead of a guessing game.
No. 04 — Git & GitHub
Version control from first principles to daily practice: branches, merge and rebase, undoing mistakes safely, the GitHub flow, Actions, releases, and even Git for hardware projects with Git LFS — for makers and students, not just professional developers.
Leonardo Galli — software engineer and football referee based in Milan, Italy.
Builds open-source tools daily, works with electronics and radio, and writes books that pair every chapter with a real exercise instead of just theory.
