Developer turns iPhone and smart plug into darkroom f-stop timer
Original: Show HN: I turned my iPhone and a $20 smart plug into an f-stop timer
A developer has shared a DIY project that pairs an iPhone with a $20 smart plug to build an f-stop timer for photographic darkroom printing. The tool controls enlarger exposure timing in precise fractions of stops, replacing dedicated darkroom timers that can cost far more. Hacker News readers are discussing the build, its accuracy, and whether consumer smart plugs are reliable enough for consistent print exposures.
Why now: The low-cost, phone-based twist on a piece of niche analog photography equipment is drawing curiosity and debate among makers and film photography enthusiasts.
