## Summary

A maker built a calorie tracker that runs MiniCPM-V-4.7-35B-A3B locally on a phone to identify food from photos and estimate calories. The phone syncs daily intake to an ESP32 display with a green, yellow, and red progress ring, and the project is open-sourced on GitHub at emwstudio/esp32-intake. The calorie figures are model estimates, meant for daily logging and reminders.

> 手机本地大模型＋ESP32：我做了个热量摄入提醒器
> 
> 本期做了一个开源小项目：用手机拍一下正在吃的，本地大模型识别食物并估算热量，再用一块 ESP32 小屏幕同步显示每日摄入进度。
> 
> 方案明细：
> 
> 手机 App：本地部署 MiniCPM-V-4.7-35B-A3B，在手机本地完成图片理解
> 
> 热量估算：列出识别到的食物，分别估算热量并展示合计
> 
> ESP32 屏幕：同步 App 中的今日数据，直观显示每日摄入进度
> 
> 圆环提示：用绿色、黄色和红色区分当前热量摄入状态
> 
> 磁吸装置：可以吸在冰箱门上，也能放在咖啡机旁或零食区附近

> 热量数值为模型估算，适合日常记录与摄入提醒。
> 
> 项目已开源至 esp32-intake仓库：https://github.com/emwstudio/esp32-intake
