Hi HN! Last year the project I launched here got a lot of good feedback on creating speech to speech AI on the ESP32. Recently I revamped the whole stack, iterated on that feedback and made our project fully open-source—all of the client, hardware, firmware code. This Github repo turns an ESP32-S3 into a realtime AI speech companion using the OpenAI Realtime API, Arduino WebSockets, Deno Edge Functions, and a full-stack web interface. You can talk to your own custom AI character, and it responds instantly. I couldn't find a resource that helped set up a reliable, secure websocket (WSS) AI…

Heeey! I built a macOS copilot that has been useful to me, so I open sourced it in case others would find it useful too. It's pretty simple: - Use a keyboard shortcut to take a screenshot of your active macOS window and start recording the microphone. - Speak your question, then press the keyboard shortcut again to send your question + screenshot off to OpenAI Vision - The Vision response is presented in-context/overlayed over the active window, and spoken to you as audio. - The app keeps running in the background, only taking a screenshot/listening when activated by keyboard…

As the Home Assistant project says, it's the year of voice! I love Home Assistant and I've always thought the ESP BOX[0] hardware is cool. I finally got around to starting a project to use the ESP BOX hardware with Home Assistant and other platforms. Why? - It's actually "Alexa/Echo competitive". Wake word detection, voice activity detection, echo cancellation, automatic gain control, and high quality audio for $50 means with Willow and the support of Home Assistant there are no compromises on looks, quality, accuracy, speed, and cost. - It's cheap. With a touch LCD display, dual…

hi! video[0] The idea is you could carry around this hardware and ask it any questions about the conference. Who is speaking, what are they speaking about etc... it connects via WebRTC to a LLM and you get a bunch of info. This is a workshop/demo project I did for a conference. When I was talking to the organizers I mentioned that I enjoy doing hardware + WebRTC projects. They thought that was cool and so we ran with it. I have been doing these ESP32 + voice ai projects for a bit now. Started with an embedded sdk for livekit[1] that jul 2024 and been noodling with it since then. This…

I was laid off recently and, instead of looking for another job right away, I decided to build something I always wanted: a transcription tool that respects user privacy. Existing transcription tools often require internet connectivity, send your private audio to cloud servers, or lock you into monthly subscriptions. I wanted something different—so I built WhisperBuddy, a privacy-first AI transcription app that runs entirely on your machine. WhisperBuddy uses OpenAI’s Whisper model (see: https://github.com/openai/whisper). While the model may not always deliver the…

My friend built this and I'm blown away with how much fun it is and the high level of polish. It renders 9 different strange attractors (Lorenz, Rössler, Aizawa, Chen, etc.) as particle systems — thousands of particles tracing chaotic paths in real time. You can rotate and zoom with touch/trackpad in 3D. The sound is the part that surprised me. It's not a soundtrack — the audio is generated from the motion itself using spatial audio, so tones shift as the attractor's behavior changes and the sound moves around you as you rotate the form. Put on headphones. The Playdate version uses the…
