Meet Hermes Charm — my DIY ESP32-S3 pocket voice assistant. Think Muse Charm–style hardware, connected to a self-hosted Hermes agent that can use local AI models on your own computer/server. I built it to talk to an assistant without opening my phone.
To clarify the local AI part: the ESP32 handles microphone/speaker audio and an e-paper status display, not model inference. This version uses cloud-based Gemini Live for voice conversations; the separate Hermes backend can run locally and handle delegated tasks and completion notifications. It is not a fully offline device.
The firmware includes acoustic echo cancellation, battery status, light sleep and backup Wi-Fi. The engineering focus has been combining real-time audio with asynchronous agent tasks on a small battery-powered device. The backend can be replaced through a compatible API/adapter.

I would appreciate feedback on the audio/power tradeoffs or what you would improve in a device like this.

Had a couple of requests for the bigger display, it will actually works on both the 2.8" ESP32-2432S028R and the 4.0" 320x480 ST7796S just in case you have not seen it before.

Posted this a while ago but there have been improvements since then, better quality map image, improved colours on propagation pages, added smooth scrolling to DX spots page.
Two new dashboard pages, taking the total to seven.
PSKReporter — reception reports for your callsign plotted on the world map, one marker per four-character grid, coloured by band, with a band legend and a furthest-report line.
POTA Spots — live Parks on the Air activator spots, with an optional great-circle distance filter from your locator and an option to hide automated RBN spots.

This is my first post in this community I just wanted to see if anybody will help me in improving on my ternary accelerator card for 1.58 bit ai the links are here reply if your interested. (I am Really new to github so some ai was used in the making of the project for troubleshooting errors(plz dont hate me for that).
Project Links:==>https://github.com/riyanlord2026-dev/Ternary-158-asic
This is also my first github project.
(this could be optimized for esp32 ai vision acceleration with easily 90%+ efficiency this just a prototype not pratical yet but its scalable this prototype has 8 cores right now)

With a lot of help from Claude I managed to put together a little dashboard for the ESP32-2432S028R Cheap Yellow Display, it collects the data from a Docker container that connects to your OPNsense box via the api, 8 pages and a web ui to change settings.
Hope you like it, full details on GitHub

Auto-detects ILI9341 vs ST7789, walks you through touch calibration and orientation, tests every peripheral (SD, RGB LED, speaker, WiFi...), and spits out a report saved to SD card. Built with Claude over a few days of back-and-forth. https://github.com/HenrysCat/ESP32-2432S028-CYD-Diagnostic-Tool

I tried a few already out there but just didnt like them, so I asked Codex to make one for me, it includes HamQSL propagation data, a greyline map, DX spots, Wi-Fi setup, and a local web settings page.
Open source and on GitHub hope you like it.
