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 turns an iPhone and a cheap smart plug into an f-stop timer for photographic darkrooms, detailed on a personal site. The low-cost build lets film photographers control exposure timing without buying dedicated enlarger timers, and Hacker News readers are discussing the clever hack and its setup.

Why now: The project's low-cost, creative reuse of everyday hardware appeals to the DIY and analog photography community.
