This post geeked out on voice AI integration: wooden desk clutter with headphones, Blue Yeti mic, scattered cables, but Sentinel Core shines—green PCB with black heatsink, lit green Ethernet, USB mic plugged, monitor hinting HA dashboard. Demos "Okay Nabu, how much does an elephant eat?"—GPU spins for offline Hermes 8B via Home Assistant Voice PE, responds via Docker whisper.cpp/Piper. Wake-word tuning woes ("HEY NABU!"), but cloud-free local LLM breakthrough— "alien in my house" vibe for couch commands, blending hardware with open-source glue.
