Selfhosted

To become independent, you don't have to ask for independence. To become independent you have to be independent.

This is the story of how I am slowly becoming independent. Disclaimer: If you don't understand anything, that's fine. I created this documentation for myself.

Why am I doing this

My name is Francisco, in french it means "free person" . Some people in life want performance, some other want reliability. The only thing I care about is freedom. To do what I want, when I want and how I want to.

Current infrastructure

Server: Intel NUC 11, 16 GB RAM, 1 TB NVMe. Ubuntu Server. Connected via 1 Gbps symmetric FTTH (dynamic IP). eGPU (Razer Core X + RTX 2070 Super) currently offline — PSU dead since 2026-03-04.

RPi 5 (pibot1): Mounted in the G Mobile Lab (vehicle). Runs Bluetti BLE bridge, I2C sensors (CO2, temp, humidity, pressure), GPS NEO-6M, IMU MPU-6050, and Starlink gRPC telemetry. Connects to server via Starlink + Tailscale.

Previous servers (non-operational):
