I still remember the day a North American colleague, visiting our office in São Paulo, asked why we didn’t just “spin up another cloud instance” to handle a sudden traffic spike for a client. He was a sharp engineer, no doubt about it. But his question came from a place where fiber connections hum quietly… Read More: The Problem With Western Tech Assumptions About Infrastructure Availability »
By Diego Almeida I remember the first time I watched a colleague from California try to deploy a soil-moisture sensor network in the semi-arid interior of Pernambuco. He had a laptop, a brand-new LoRaWAN gateway, and a very firm belief that the hardest part would be calibrating the sensors. Five hours later, we were still… Read More: Power, Politics, and the Grid You Don’t Have: The Problem… »
First time I packed for a remote monitoring job in the interior of São Paulo, I stuffed my bag like I was heading to a tidy industrial park. Laptop, a handful of microcontrollers, some cables, and a head full of textbook assumptions about how things should work. The site, I was told, had power and… Read More: The Hidden Cost of Assuming the Grid Will Always Be… »
The Blind Mechanic’s Toolkit: Making Sense of Silent Failures I’ve lost count of the times I’ve stood over a prototype board, multimeter in one hand, coffee in the other, absolutely certain the problem was invisible. No scorch marks. No cracked traces. No swollen capacitors winking at me. The board simply refused to work, and I… Read More: How to Debug Hardware When You Cannot See What Is… »
Introduction: The Invisible Fault Most hardware troubleshooting starts with a good look at the board. Burn marks, a swollen capacitor, maybe a cracked trace—if you can see it, you’re halfway there. But what about the board that looks pristine and still won’t power up? I’m Diego Almeida, writing for fortec-br.org, and I’ve spent years in… Read More: Introduction: The Invisible Fault »
There’s a particular kind of silence in the lab when you’ve been staring at the same board for an hour. No LEDs flickering, the display stays dark, and your multimeter stubbornly reads zero where you expected 3.3 volts. I’m Diego Almeida. I’ve done my time in Brazilian prototyping shops and on European production lines, and… Read More: Debugging Hardware Blind: An Engineer’s Field Notes »
I still remember my first day at a German university’s robotics lab. The professor handed me a soldering iron and a half-built sensor board before I even found a chair. No long theory preamble, no PowerPoint slides—just a bench, tools, and a problem to solve. It was the opposite of what I’d lived through in… Read More: Why Brazilian Engineering Education Needs More Practical Labs »
Why the Gap Between Prototype and Product Matters Every embedded engineer knows the feeling: a blinking LED on a breadboard, a sensor spitting raw data on a serial monitor, and the quiet satisfaction of a first proof-of-concept. But turning that tangle of wires and breakout boards into a sealed, reliable device that survives a factory… Read More: The Difference Between Prototyping and Production in Embedded Systems »
Por Diego Almeida — engenheiro eletrônico que já queimou placa em protótipo e em produção, e aprendeu a diferença na prática. Quem nunca ouviu aquela frase: “Funcionou no protótipo, mas na produção deu tudo errado”? Se você trabalha com sistemas embarcados, provavelmente já viveu essa história — ou vai viver. A transição do protótipo para… Read More: From Breadboard to Production: What Really Changes in Embedded Systems »
Every embedded project starts in the same place: a bench cluttered with wires, a blinking LED, a microcontroller dev board held down by its USB cable. It works. You celebrate. Then someone asks the question that changes everything — “Can we build ten thousand of these?” Suddenly, that breadboard prototype isn’t enough. This is the… Read More: From Breadboard to Board: The Real Difference Between Prototyping and… »
