Help keep the lights on.
Everything below runs on servers I own and pay for myself. If you enjoy any of it, a one-off coffee or a monthly membership helps keep it running.

Rádio Frequência Zero →
A Portuguese radio station that runs entirely on its own, 24/7. AI picks the music and writes and voices the news and weather. No presenters, no ads — a research project into how far an automated station can go.
Castro's Cloud →
A private cloud for family and friends: photos, files, passwords, audiobooks, movies and series behind a single login. Free to join, and it stays that way.
The homelab
Kubernetes on Proxmox, a storage server, GPUs for running AI models locally, and a small cloud server at the edge — all self-hosted, open-source, and maintained in my spare time.
Where it goes
- Electricity to keep the servers running around the clock
- Replacement hard drives — they do fail
- The edge server, domains, and the AI usage the radio still depends on
- New hardware as the projects grow
