Most bird-ID apps need signal, hold your attention on a screen, and send your audio and location to a server. TrailEar listens through the mic, gives a quiet cue when it detects a bird, and saves the details for a summary after the walk.</p> <p>It’s for beginner and casual birders who want to learn calls without staring at a phone.</p> <p><strong>Demo:</strong><br> <strong>Run locally:</strong><br> uvicorn trailear.backend.api:app --host 127.0.0.1 --port 8000</p> <p><strong>Code:</strong><br> <a href="https://github.com/DhirajB05/HacktoberFest_C2.git" rel="noopener noreferrer">https://github.com/DhirajB05/HacktoberFest_C2.git</a></p> <p>FastAPI backend, SQLite storage, and a static HTML/JS frontend with six views (Home, Setup, Live, Summary, History, About).</p> <p><strong>How I Built It</strong><br> <strong>Detection:</strong> BirdNET-Analyzer on 3-second mic windows (sounddevice, 48 kHz mono), with a confidence threshold and a 60-second cooldown per species so cues stay rare. <br> <a href="https://dev.tourl">Summaries:</a> a small local LLM through Ollama or llama.cpp. It only summarizes the detection list plus a static species file, and is told not to add facts.<br> Live cues: server-sent events, so there is no extra infrastructure.<br> Privacy by design: the server binds to localhost, there is no telemetry, and there are no runtime network calls.</p> <p><strong>Why Does Open Innovation Matter?</strong><br> Works with no signal. A cloud API fails exactly where trails are.<br> Your data stays yours. Audio and GPS history never leave the device.<br> Costs nothing to run. There are no per-call fees.<br> Swappable parts. The LLM or the detection model can be replaced without touching the rest.<br> Honest limits. Small local models are weaker than closed ones, which is why the LLM only does constrained summaries.</p> <p><strong>My Agent Session</strong></p> <p>Built with the opencode agent framework: backend scaffolding, audio capture, the frontend, and end-to-end testing.<br> <strong>Session link:</strong><a href="https://opncd.ai/share/STkDsk70" rel="noopener noreferrer">https://opncd.ai/share/STkDsk70</a></p> devchallenge hf26challenge gemmachallenge opensource DHIRAJ BHAVIKATTI Mon, 05 Oct 2026 10:00:52 +0000 https://dev.to/dhirajb05/hi-there-im-new-to-dev-community-m3e https://dev.to/dhirajb05/hi-there-im-new-to-dev-community-m3e
