痛点：暗房放大/冲印爱好者想要专业级 f-stop 定时器，但市面产品动辄几百美元太贵，且需要专门的硬件设备

目标用户：自建暗房的胶片摄影师、暗房冲印爱好者（业余/半专业）

证据：always wanted one of the proper, advanced f-stop timers, but never really wanted to spend a couple hundred dollars on one... I built Darkplug around a cheap smart plug

变现：一次性付费 App（如 15-30 美元）+ 引导搭配 20 美元智能插座的低成本硬件方案；或做 Pro 订阅解锁高级功能

MVP：用本地网络协议控制智能插座开关放大机，实现普通计时、f-stop 计时、测试条、遮挡/加光工作流、分阶（双通道）和相纸显影计时——作者已用 Codex 独自完成，可复刻

竞品：RH Designs f-stop timers、Zone VI 定时器、Intrepid 暗房定时器、各类 Darkroom Timer App

摘要：一位胶片摄影师用 iPhone + 20 美元智能插座做了 Darkplug 暗房定时 App，支持 f-stop 计时、测试条、分阶和相纸显影计时，用来替代几百美元的专业 f-stop 定时器。帖子发布在 Show HN，仅 7 分 0 评论，热度很低。市场真实存在（多款商用暗房定时器售价数百美元），但属小众垂直领域，独立开发者两周可复刻。
