In a world often dominated by negative news, this digital picture frame offers a moment of respite through playful, uplifting messages about imaginary utopias.\n\nExamples of messages you might see:\n- \"Ewiger Sommer niemals zu heiss\"\n- \"Laechelnde Baeume sprechende Blumen\"\n- \"Pizza ist gesund\"\n- \"Weltfrieden garantiert\"\n\nThe display shows messages in random colors, creating a constantly changing kaleidoscope of positive possibilities.\n\n## Hardware\n\n- 64x64 RGB LED Matrix Display (HUB75 interface)\n- ESP32 microcontroller\n- Power supply (5V)\n- Boot button (GPIO0) for time setup\n\n## Features\n\n- Displays messages in random colors for visual variety\n- Changes message every 30 seconds\n- Completely offline operation\n- Built-in collection of whimsical utopian messages\n- Low memory footprint\n- Simple and reliable operation\n- Power-saving sleep mode (22:00-07:00)\n\n## Technical Details\n\n### Dependencies\n\n- ESP32-HUB75-MatrixPanel-I2S-DMA\n\n### Display Configuration\n\n- Resolution: 64x64 pixels\n- Interface: HUB75\n- Driver: FM6124\n- Brightness: 100/255 (configurable)\n- Update Interval: 30 seconds\n\n## Setup Instructions\n\n1. Install the required libraries in your Arduino IDE:\n   - ESP32-HUB75-MatrixPanel-I2S-DMA\n2. Connect the ESP32 to your LED matrix following HUB75 pinout\n3. Upload the code to your ESP32\n4. On first boot, use the boot button to set the time:\n   - Short press: Increment hour (0-23)\n   - Long press (2 seconds): Confirm time\n5. The device will now run automatically, sleeping between 22:00 and 07:00\n\n## Customization\n\nTo add or modify messages, edit the `utopias` array in the main `.ino` file. Each message should be a string that fits comfortably on the display. The system automatically handles word wrapping and display formatting.\n\n## Background\n\nIn a world where news feeds and social media often amplify negative events, Framed Utopia aims to create tiny moments of joy through absurd and delightful possibilities. It's not about ignoring reality – it's about remembering that imagination and whimsy have their place in making our day a little brighter.\n\n## License\n\nThis project is open source and available under the MIT License.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesshahn%2Fesp32-dotmatrix-utopia-offline","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fesshahn%2Fesp32-dotmatrix-utopia-offline","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fesshahn%2Fesp32-dotmatrix-utopia-offline/lists"}
