Thinking in Public: An Engineering Notebook
I never really had a space that felt like mine. A place where I could think out loud without worrying I’m taking up too much of someone’s time, or not being polished enough, or not having the right credentials to be saying this.
I spent a long time trying to be the guy who had it figured out. Well-read. Precise. The person with the answer already prepared. And somewhere in there I stopped letting myself ramble.
This is me giving myself permission to ramble.
I’m going to write bad puns. Half-formed ideas. Things I’ll probably get wrong. And I want people to push back when that happens — not because I’m performing humility, but because I’m genuinely not interested in pretending I don’t make mistakes.
So — who am I, roughly. I’m a cat person. I’m Brazilian. I’m technically a licensed electrician, mostly because I was already doing questionable electrical work and figured I should probably become legally qualified before I electrocuted myself in someone else’s house. I almost studied economics — that was actually my first college — so I was the crazy spreadsheet guy before I became the crazy 3D printing guy. You’ll probably see both of those people show up here.
The 3D printing thing got bad. I’ve been obsessed since I was sixteen. I have three printers right now. I’ve designed a printer in each of the major styles that exist. My close friends will tell you it’s basically all I talk about. Right now I’m building a slicer from scratch because one of my designs needed a specific feature that didn’t exist, and apparently my response to that was
Two years of thinking about it, two months of serious research, and now I’m making actual progress.
But this blog is going to wander past that. There are already three posts here — one about a project management tool I built for AI agents, one is a letter to a friend who just got into 3D printing, one is a debug story about compiling a Wi-Fi driver with no internet, no Ethernet, and a USB adapter whose drivers assumed Windows.
Three completely different things. That’s kind of on purpose.
I tend to follow things deeper than I should. That’s probably the only real pattern here.
