    ESP32-based project, streams live I2S-microphone data over WiFi Access Point

    This project might be a good starting point if you want a device that streams audio data to many listeners — for example, audio streaming for excursions, guided tours, etc.

    I had a few iterations with this project. The first iteration started in 2024; I was experimenting with Raspberry Pi and gstreamer at that time. I couldn’t beat the high latency of web streaming — obviously the issue was that httpd wasn’t configured to use websockets. I abandoned this idea afterwards. Back in 2026, after switching to ESP32, I was able (with AI help) to reach a desirable result. It supports 10 simultaneous connections. HERE you can find the repo with the project and all HOWTOs in README.md.

  • Lightweight video looper for headless Raspberry Pi

    Lightweight video looper for headless Raspberry Pi

    Description

    This project is intended for those who want to loop a video on the HDMI display without occupying a laptop/PC for this simple task. To control video playback you just need a prepared Raspberry Pi board and a USB drive with the video source (won’t be permanently connected). The project has a few more useful features and examples to use. The project is tested on Raspberry Pi Zero W and Raspberry Pi 4 hardware.

    In this short video I insert a USB stick with the config that: copies 3 video files from USB drive, shows all copied files, starts playing the copied file video.mp4:


    The repository with the looper is located HERE. Feel free to try or/and exetend it. The full description and how to deploy is in README.md file. Looking forward for your feedback. Happy codding!
