Tomorrow I’m starting the build guide for something I’m calling ZeroSentinel.
What ZeroSentinel does:
- Turns a $15 Raspberry Pi Zero into a fully autonomous privacy node
- Builds a locked, authenticated WireGuard tunnel home from anywhere
- Runs your DNS through your own Unbound resolver with DNSSEC enforcement
- Blocks ISP meddling, hotel rewrites, captive portal tricks, and upstream manipulation
- Monitors its own health every few minutes
- Sends you an encrypted Nostr DM when anything breaks
- Enforces no-fallback DNS and drops all traffic that isn’t in the tunnel
- Works behind travel routers, double NAT, carrier-grade NAT, and hostile networks
- Makes your phone’s “VPN” actually mean something
Your own infrastructure. Quiet. Cheap. No subscriptions. No external services.
