| OpenAI API | ~€3/month |
I'm documenting the build process:
- Building Safe Bite: Why I'm Making This — The personal story behind this project
- Building Safe Bite: Offline Mode — Coming soon
- Inspired by this LinkedIn post
- FODMAP data based on Monash University guidelines
- CH34x USB driver for macOS — Required for M5StickC Plus2 serial connection
- arduinohw — The project that inspired Safe Bite
