Berlin-based Geek
Hello world. I'm building lokkal.space as a therapeutic hobby during the long Berlin winters.
Unlike robust enterprise data centers, my lab thrives on constraint. The goal isn't just raw power—it's efficiency and resourcefulness.
I repurpose old hardware that others discard, turning potential e-waste into functional, learning-rich environments. It's about taking control of your data without breaking the bank or the power grid.

What I'm Running
Tutorials and showcases covering the stack.
Home Server
The core of the lab. Hardware selection, hypervisors (Proxmox/ESXi), and bare metal setups.
Media Server
Jellyfin/Plex implementations. Transcoding on low-power hardware and library management.
NAS & Storage
Unraid/TrueNAS or custom ZFS builds. Reliable storage strategies for data hoarders.
Home Networking
VLANs, firewalls (OPNsense), and structuring a secure internal network.
Security & VPN
WireGuard, Tailscale, and secure remote access strategies to keep the bad guys out.
Monitoring & Alerting
Grafana, Prometheus, and Uptime Kuma. Knowing when things break before you need them.
Home Automation
Home Assistant integrations to make the apartment smarter and more energy efficient.
Backup Strategy
3-2-1 backup rules. BorgBackup, Restic, and offsite synchronization.
Dashboards
Homepage, Dashy, or custom landing pages to organize all your local services.
Sustainable Computing
My homelab journey isn't just about software; it's about hardware lifecycles. I focus on energy efficiency as a primary goal. Using low-power mini PCs, ARM-based SBCs, and spinning down drives when not in use helps keep the Berlin electric bill manageable while preventing perfectly good electronics from becoming landfill.
