Model-driven jet-lag light scheduler — simulates your circadian pacemaker (Forger–Jewett–Kronauer) and finds the light/dark plan that re-entrains you fastest. Runs in your browser. 用生物钟模型算最快倒时差的光照时间表,纯前端、数据不出本地。

Open-source wearable circadian phototherapy gear for polar nights. Features an unnetworked microcontroller and an edge-lit brim diffuser directing a 5-stage variable-spectrum light sequence (460nm blue to 660nm red) down to lower retinal ipRGC receptors, providing distinct, non-continuous diurnal anchors using <2Wh daily.
