Trashmonitor to oggle my goggles and behold the blinkenlights
I glued together a tittle tailnet-only streaming surface so I can oggle my goggles, blinkenlights, dev boards, and the hardware pile from the sanctum of anywhere

Hacking around with XGS-PON: Fiber ISPs, WAS-110 Modules & Mikrotik
Two fiber ISPs, one switch, two BFW WAS-110 SFP+ XGS-PON modules running 8311 community firmware.

This is the procedure I used to land both, with annotated scripts and OMCI captures.
