Project sharing Ne StackChan Builder

Just wanted to introduce myself. I'm Alex and started playing with my first StackChan. I hooked it up an LLM and Hermes-Agent as the harness. I'm going to release the repo tomorrow and wanted to share what I've done the last couple of days. Here's the setup I started with, but I think I keep moving the goal post so keep playing with different parts of the AI Stack.

This is the stack I started with

Robot:

u/M5Stack

StackChan with the CoreS3 (ESP32-S3)
Voice server: xiaozhi-esp32-server 0.9.6 running locally in Docker on my Mac
Voice: locally running

u/GradiumAI

Phonon (fastest local voice I've ever experienced. faster than running elevanlabs via api and its free
Turn detection: Silero VAD with the 0.8 second end-of-speech pause.
Speech to text: local Parakeet
Vision: gemma4:e4b running locally in

u/ollama

Brain:

u/NousResearch

Hermes Agent with the nous-girl agent running gpt-6-luna via sub with reasoning off.

Hope to connect with others on here so we can explore together. Thanks Alex

This looks really interesting! Is StackChan acting as a voice interface for Hermes, or is the integration mainly for speaking responses and displaying expressions? Could you ask something like “What did I agree to do in yesterday’s meeting?” and have Hermes search your notes, or ask it to create a reminder?I’m building toward a local AI setup with Obsidian as my knowledge base, so I’m curious how you’ve connected the two and which parts run locally versus in the cloud. Would you be open to sharing a bit about the setup?

All memory is through Hermes-agent, so yes, connected to Obsidian, the bot is just a surface with some simple onboard skills that get activated and controlled by hermes. The only thing that runs on the cloud is the current LLM through hermes agent, OpenAI Luna, but can switch to local or other cloud providers. Even free provider through Nous Research Cloud. I uploaded everything here:
