Today the tech world says goodbye to John C. Dvorak, who passed away on Monday, July 20, 2026, at the age of 80, following complications from recent heart bypass surgery. He is survived by his wife, children, and grandchildren, and remembered by colleagues and readers as a writer who never softened an opinion to make Continue reading RIP John C. Dvorak (1946–2026)
Voltron assembles from five lions. The Valkyrie in Macross folds from a fighter jet into a battle-ready mecha. The Autobots have been telling us for forty years that there s more than meets the eye. Transformation is one of gaming and animation s oldest tricks — take something familiar, and reveal it was always capable of becoming Continue reading From a Transforming Ship to a Transforming Engine
In the original Macross series, the SDF-1 doesn t set out to fight anyone. It launches because an alien fleet is already on its way and there is no other choice. The ship is barely understood, its fold drive untested, its crew a mix of civilians and soldiers who never signed up for an interstellar war. Continue reading Building a Custom Drone Controller from Scratch — Part 5: BLE HID Gamepad Host
If you ve seen Pacific Rim, you know the core idea behind a Jaeger: a pilot doesn t push buttons to make the giant robot punch — they punch, and the robot punches with them. The machine reads the pilot s body and mirrors it. That s the exact idea behind the first control mode I built for the Continue reading Building a Custom Drone Controller from Scratch — Part 4: Accelerometer Tilt Control
In Part 1 we talked about why this project exists and what hardware it runs on, and in Part 2 we reverse-engineered the UDP protocol that lets an M5Stack AtomS3 talk to a cheap WiFi toy drone. Before going further into flight control and gamepad support, it s worth stopping to look at how the firmware Continue reading Building a Custom Drone Controller from Scratch — Part 3: Firmware Architecture…
In Part 1 we introduced the project: a custom WiFi flight controller for Eachine E88/E58 toy drones running on an M5Stack AtomS3. But before writing a single line of firmware, there was a much bigger problem to solve — nobody publishes the protocol these drones speak. No SDK, no documentation, no public spec. If you Continue reading Building a Custom Drone Controller from Scratch — Part 2: Reverse…
Toy drones are everywhere. You can pick up an Eachine E88 or E58 for under $30, fly it around your living room, and have a decent time. But what happens when the official app stops working, the manufacturer disappears, or you simply want to understand what s actually happening between your phone and that spinning plastic Continue reading Building a Custom Drone Controller from Scratch — Part 1:…
Após algum tempo sem posts aqui no blog, deixo esse post sobre um novo projeto que deixei público no GitHub, onde demonstro como integrar projetos escritos em C com bibliotecas escritas em Rust (o inverso também é possível), utilizando CMake e todo ferramental disponível no ecossistema do Rust. O projeto em questão é o weather-bot Continue reading C vs Rust
Finalmente após algum período longe do desenvolvimento de software para MSX, decidi voltar ao game unindo o útil mundo do IoT ao agradável universo de retrocomputing através do nosso querido e amado MSX. Como se trata de um tema atual, rico de informações e possibilidades, decidi escrever dois artigos sendo esse aqui o primeiro que Continue reading MSX LoRa First contact
Após um período de hiato voltamos a lançar mais uma edição da Revista MSX Brasil Oficial que de fato estava no forno desde inicio de 2020 entretanto com os acontecimentos mundiais ocorridos nesses últimos 2 anos, a prioridade dessa edição diminuiu bastante a ponto de praticamente cancelarmos todo o planejamento original e repensarmos a mesma Continue reading Revista MSX Brasil Oficial No 3
