A while back I bought a Nissan 200sx. Naturally, the only proper repair info that exists is a 500-page workshop manual scanned out of a 1990s binder, full of grainy diagrams and torque tables that you navigate with Cmd+F and a lot of patience. So I started building the thing I wanted: a real, clickable, searchable, mobile-friendly version of that manual. That side project grew an umbrella name — sucatisse (Portuguese-flavoured slang for “scrappy stuff”) — and now hosts two manuals so far: ...

I’ve been running services at home for a while now, but everything was scattered across different machines with no real orchestration. I finally decided to go all-in and build a proper Kubernetes cluster at home, and I’m really happy with how it turned out. This is the story of how I did it. The hardware The cluster is called Magi (yes, the Evangelion reference), and it runs on a mix of amd64 and ARM nodes: ...

I fell down a rabbit hole last weekend and came back with a thing: CETsize — a tiny web app that measures whale body length from drone photos, right in your browser, no uploads, no servers. Live: whales.luisg.me Here’s a quick peek at the app UI — load a photo, zoom/pan, and lay down straight or curved measurements: This started with Jan Hofman’s R program (massive shout‑out 🙌). I loved the idea and wanted something biologists could run anywhere without installing R or touching a terminal. Also… I’ve been exploring agents + GitHub Copilot, so this was the perfect excuse to see how far I could push a browser‑only build. ...

I’ve always loved my Gameboy Advance (GBA), but after years of use, it was time for an upgrade. I decided to breathe new life into my old handheld, which I bought for just 1 single euro from an old colleague in school who was about to throw it into the trash. Mixing nostalgic design with modern tech, here’s how I transformed it from an old-school relic into a portable powerhouse. ...

Introduction When I decided to upgrade the audio system in my shitbox 1989 Nissan 200SX, I wanted to install new JBL 6.5-inch speakers on the front doors to pair with my new Pioneer dual-din touch screen radio (SPH-DA160DAB). The stock speakers were old and small, so I embarked on a quest to find a suitable solution. After extensive research and exploring different approaches, I wanted to create a 3D printed piece to imitate the original plastic trim that holds the speaker, however I eventually arrived at the simple DIY solution using MDF (Medium-Density Fiberboard) and some basic tools with a touch of paint, because only I will see the inside of the door and it has to look pretty for me, right? ...

I’m excited to share with you all the things I’ve learned over the years, from kubernetes and clouds ☁️ to music and old japanese cars. My interests are diverse, and I hope that you’ll find something that interests you too. To get started, I wanted to explain a little bit about how I set up this website. I used GitHub Pages to host the site, which is a great way to host a static website for free. I used Hugo, a static site generator, to create the site, and PaperMod, a Hugo theme, to make it look good. And, to automate the process of updating the site, I set up a pipeline that updates the site every time I commit changes to the repository. It’s a pretty slick setup, and I’m really happy with how it turned out. ...
