AI Smart Lunchbox · Know what your child ate at school, by dinner time
The 'Little Lunchbox' student smart lunchbox: open the lid and it weighs automatically — zero operation for kids. Eating pace, picky-eating index, food-photo recognition and AI diet reports for parents in the app. Fully sealed IP67, wireless charging, Standard ¥299 / Locator ¥499 — open for crowdfunding.

What it brings you
Zero operation for kids
A hall sensor detects the lid opening and a 10Hz weight curve logs the whole meal — no charging, no check-ins, no buttons, no screen, no sound. Kids just eat normally.
Weighs accurately
±1g at room temperature, ±3g through hot meals (≤85℃); auto taring, temperature compensation and 3-point factory calibration.
Beyond weight — how they eat
Meal duration, pace and rhythm curves plus a 14-day picky-eating index — 'finished in 13 minutes, 52% of the greens left'.
Photo food recognition
Snap a photo in the morning to identify each compartment (target: 30 categories ≥85%); leftover estimates always labeled with confidence.
AI reports & weekly digest
One dietary tip per day from a school-age dietary-guideline script library with red-line word filtering — never fabricated; weekly trend report every Sunday.
Locator edition for safety
4G + BeiDou + Wi-Fi fused positioning with school-arrival / leave / home-arrival push — safety without giving your child another screen.
Transparent R&D progress
The percentage is assessed from completed milestones across the whole development plan, and updated as development moves forward.
✅ Completed
- ✅Software fully delivered and field-tested: cloud meal-reconstruction engine, daily / weekly reports and AI tips (with red-line filtering), geofence state machine, device onboarding — 6/6 automated tests passing
- ✅Parent PWA verified in browser: today report / trends / weekly / positioning / multi-child binding, 6 themes + 7 languages
- ✅Device simulator: 10 simulated school days validated end-to-end
- ✅Firmware source structure complete: 11 C modules + dual-partition OTA (ESP-IDF v5.1+, pending on-board bring-up)
- ✅5 project documents ready: market validation plan / PRD / hardware BOM / cloud architecture / positioning spec
🚧 In progress / next
- ⬜Market validation (current P0): surveys n≥300 + depth interviews in 2–3 cities, Go/No-Go hypothesis testing
- ⬜Firmware on-board bring-up: accelerometer / locator module integration, replace placeholder certificates
- ⬜EVT 50 handsets → DVT 200 pilot units + 100-family field test
- ⬜Real food-recognition model integration (rule-based stub for now)

We put risks on the table
Crowdfunding means sharing development uncertainty with us — please read these before backing.
- Market-validation risk: validation (surveys + interviews) is in progress. If key hypotheses fail, we will adjust or cancel the project with full refunds — honesty over shipping at all costs.
- Hardware delivery: firmware awaits board bring-up; EVT/DVT/PVT must complete before mass production, so first batches may slip. Weekly updates on the site.
- Recognition accuracy: food-photo recognition targets 30 categories at ≥85%; household dish variety may affect estimates, which are always labeled with confidence.
- School environment: lunch rules differ by school (whether personal lunchboxes are allowed) — please confirm with your school before purchase.
