Agentic Gadget

Unified monorepo for the Agentic Gadget hardware, firmware, local agent, cloud relay, and Bluetooth audio bridge.

Layout

firmware/nrf9160 — nRF9160 DK firmware (Zephyr/NCS)
firmware/esp32-airpods-bridge — HUZZAH32 Bluetooth A2DP audio bridge
software/ai-pendant-simulator — local Mac agent, cloud relay, and simulator
software/dashboard-sveltekit — Mission Control dashboard (Cloudflare Worker)
hardware — datasheets, electrical design, and KiCad sources
docs — build guides and architecture notes

Local agent

Keep private credentials in the repo-root .env (see .env.example). That file is ignored by Git.

cd software/ai-pendant-simulator
npm install
npm test
npm run agent

nRF9160 firmware

Build from firmware/nrf9160 using the installed Nordic toolchain (NCS under /opt/nordic/ncs). Build directories are intentionally not stored in this repository. Private Kconfig values belong in the ignored firmware/nrf9160/secrets.conf file and must be included with -DEXTRA_CONF_FILE=secrets.conf when creating a fresh build.

source firmware/nrf9160/scripts/env.sh          # puts west/nrfutil on PATH
firmware/nrf9160/scripts/flash.sh --check       # verify probe + tools
# build (see docs/How_This_System_Runs.md), then:
firmware/nrf9160/scripts/flash.sh               # nrfutil → J-Link 960036581

ESP32 bridge: firmware/esp32-airpods-bridge/flash.sh (PlatformIO in .venv).

Questions

What parts does the Hivemind use?

29 parts, built around the DRV2605LDGS, MCP73831, TXB0102DCU and SK6812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Hivemind KiCad files?

From the agenticaiuw/hivemind repository on GitHub, at the commit this page was made from: the board is hardware/kicad/KiCad.kicad_pcb and its schematic hardware/design/agentic_gadget.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hivemind design in my own project?

Its repository states no licence, so its author keeps all rights: ask agenticaiuw before reusing the design.
