BinRange tracks whether the trash can has left its spot using UWB
What happened
A developer built BinRange, a system that uses ultra-wideband radio to tell whether a trash can has been moved out of its storage area. It runs one fixed anchor and six battery tags, tied into Home Assistant. At 10.1 meters the average reading was 10.09 meters with a 3 cm standard deviation, and first calibration came in under 2 cm of error. Outdoor readings hold to about 30 meters, with a farthest record of 37.28 meters. The build includes custom firmware, 3D-printed enclosures and wireless updates, and leaned heavily on Codex.

开发者用 UWB 无线电搭建了 BinRange：一个固定锚点加六个电池标签，配合 Home Assistant 判断垃圾桶是否已从存放区移出。实测中，10.1 米距离的平均读数为 10.09 米，标准差 3 厘米，首次校准误差不到 2 厘米；室外可靠读数约 30 米，最远记录 37.28 米。项目包含定制固件、3D 打印外壳和无线更新，构建过程大量使用 Codex。
