Trashmonitor to oggle my goggles and behold the blinkenlights

How to oggle my goggles and behold my blinkenlights while away from the basement? Here is my Sunday’s afternoon capture host project. TrashMonitor pushes H.264-over-RTSP via MediaMTX, served through a local Caddy proxy into a simple SvelteKit SPA running from one of the basement clusters.

Find the repo here: tailnet-trashmonitor

The bench view	The stream view

The whole architecture is basically “push video into the cluster, watch HLS from the tailnet.”

Piece	Job
capture/bin/trashcam-ffmpeg	read V4L2, encode H.264, publish RTSP
capture/systemd/trashcam@.service	supervise each camera path
server/mediamtx.yml	accept RTSP publishes, emit HLS, expose API and metrics
server/Caddyfile	route SPA, API, and HLS over the tailnet viewer service
spa/	static SvelteKit tiles using hls.js
server/k8s/service.yaml	expose separate Tailscale LoadBalancers for viewers and RTSP ingest

MediaMTX allows anonymous publish, read, API, metrics, and playback; the services are exposed through the Tailscale Kubernetes operator, and the reachable surface is tailnet-only. Tailnet membership is the auth boundary. The public DNS alias, if I use one, is just an A record to the Tailscale CGNAT address so my own devices get a friendly name.

This lets me walk away from the desk and still keep the goggles, boards, and blinkenlights bench weirdness in view. If a board reboots, I can see it. If a display goes dark, I can see it. :eyes: Huzzah!
