Developer Peter Szentkiralyi has shared a home-built darkroom timer that pairs an iPhone with a cheap smart plug to control photographic enlarger exposures in f-stop increments. The project, presented on Hacker News, shows how off-the-shelf hardware can replace dedicated darkroom timers, and hobbyist photographers interested in analog printing are weighing in on the simple, low-cost approach.
