on the specific hardware and software configurations used. It is provided for reference only for those who wish to create a similar system.\n\n[Go](https://go.dev/) script for acquiring and transmitting data and media stream from the various sensors mounted on the embedded system from the race car through cellular network.\n\n### Features\n\n- Collecting data from the modem, GPS, and sensors by executing [ModemManager](https://modemmanager.org/) cli commands\n- Updating [LiveKit](https://livekit.io/) room metadata at regular intervals when changes are detected\n- Creating and controlling an optimized [Chromium](https://www.chromium.org/) instance\n- Capturing and sending various streams from [Chromium](https://www.chromium.org/) to the [LiveKit](https://livekit.io/) server\n\n### Tech Stack\n\n- [Go](https://go.dev/)\n- [Chromium](https://www.chromium.org/)\n- [LiveKit](https://livekit.io/)\n- [ModemManager](https://modemmanager.org/)\n\n### Hardware\n\n- [Raspberry Pi 5](https://www.raspberrypi.com/products/raspberry-pi-5/) (8 Go)\n- [SixFab 4G/LTE Cellular Modem Kit](https://sixfab.com/product/raspberry-pi-4g-lte-modem-kit/)\n- [Battery UPS HAT](https://www.dfrobot.com/product-2840.html?srsltid=AfmBOooD28ApNQEqDY-Vkc-WCCOt0VZ2mOPo3arpIw6eJ0-mFeeHss7Z)\n- MPU6050 sensor\n- Various UVC Webcam, including Elgato Cam Link 4K\n\n### Configuration\n\nA `.env` file must be created with the information provided in `.env.example`.\nAll fields are required.\n\n#### ModemManager\n\nGrant the desired user the necessary permissions to partially control [ModemManager](https://modemmanager.org/).\nThis step is required if you want to use the [Go](https://go.dev/) script without running it with `sudo`.\n\n```bash\nsudo nano /etc/polkit-1/localauthority/50-local.d/50-modemmanager.pkla\n```\n\n```bash\n[Allow mmcli]\nIdentity=unix-user:username\nAction=org.freedesktop.ModemManager1.Device.Control\nResultAny=yes\nResultInactive=yes\nResultActive=yes\n\n[Allow mmcli location]\nIdentity=unix-user:username\nAction=org.freedesktop.ModemManager1.Location\nResultAny=yes\nResultInactive=yes\nResultActive=yes\n```\n\n```bash\nsudo systemctl restart ModemManager\n```\n\n## Author\n\n[@Minarox](https://www.github.com/Minarox)\n\n\u003cp align=\"right\"\u003e(\u003ca href=\"#top\"\u003eback to top\u003c/a\u003e)\u003c/p\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fminarox%2Fracecast-emitter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fminarox%2Fracecast-emitter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fminarox%2Fracecast-emitter/lists"}
