Daily AI generated patriotic images on the AdaFruit MagTag
This project uses GitHub Actions to automatically generate patriotic images using OpenAI's DALL-E API once per day. The images are processed and stored in the repository, making them accessible via GitHub's raw content URLs.
Clicking the right-most face button (D11) button on the MagTag plays the star spangled banner, lights red, white, and blue LEDs, and grabs the latest image from the server.
Use the included boot.py to remount the internal storage as read/write after boot. This allows for querying, storing, and displaying the Bitmap file from GitHub.
Hold down the left-most face button (D15) to disable this and instead allow your PC write to the CircuitPy drive over USB.
MagTag code is written in CircuitPython. The following libraries are required:
- adafruit_bitmap_font
- adafruit_io
- adafruit_magtag
- adafruit_minimqtt
- adafruit_requests
- adafruit_ticks
- simpleio
- Configure GitHub Secrets: Add your OpenAI API key as a repository secret named
OPENAI_API_KEY - Enable GitHub Pages (optional): For easier browsing of the image archive via the auto-generated
images/index.html - Deploy MagTag Code: Copy the contents of the
magtag/directory to your MagTag device
- GitHub Action: Runs daily at midnight UTC to generate new images
- Image Processing: Automatically resizes and converts images to MagTag-compatible format
- Image Storage: Current image saved as
images/murica.bmp, historical images archived with timestamps - Web Access: Images are accessible via GitHub raw URLs and browsable via
images/index.html
