Trace is an early prototype concept for an NFC-enabled smart scale that tracks containers, empty weights, and remaining contents.
The first version is focused on meal prep. In the intended flow, a container gets a cheap NFC tag, the scale saves its empty weight, and future weigh-ins update what is left.
- Register a container.
- Save its empty weight.
- Write or assign an NFC tag.
- Fill the container.
- Weigh it later.
- Track remaining contents through a local interface.
- local-first
- NFC read/write
- no required cloud account
- no dedicated mobile app
- container empty-weight registry
- live remaining weight
- prep-date and serving logic
- home WiFi support
- fallback direct-device access mode if possible
Meal prep and food storage.
Trace should help answer simple questions:
- What container is this?
- What did it hold?
- What is the empty weight?
- How much is left?
- When was it prepped?
- How many servings remain?
working prototype / active development.
The repo will start with documentation and design notes, then expand as hardware, firmware, and interface files are cleaned up for public release.
