DisparaTimer: A Digital F-Stop Timer for Photographic Enlargers

DisparaTimer is a highly functional application designed specifically for photographers who use analog film processing equipment. This innovative tool allows users to control the exposure process of a photo enlarger through a Raspberry Pi Pico W/WH and a power relay. By integrating these components, DisparaTimer offers an affordable and straightforward solution for setting precise exposure times. For more detailed information about the physical setup, including additional multimedia resources, visit the official website at DisparaFilm.

The core functionality of DisparaTimer lies in its dual operational modes: TIMER and STRIP. In the TIMER mode, users can easily set a specific duration for their exposures, providing precision and convenience when developing prints. Meanwhile, the STRIP mode introduces advanced capabilities by enabling the creation of test strips with incremental adjustments of fractional f-stops over a predefined base time. This feature is particularly valuable for photographers seeking to optimize their printing processes and achieve the best possible results.

To operate DisparaTimer effectively, users will require an Android device running on Android 8 or higher, with Android 9 or later being strongly recommended for optimal performance. The ideal display size for this application ranges between 5 and 10 inches, with a minimum resolution of 1280x720 pixels. However, if users encounter any issues with the aspect ratio, they can adjust the screen zoom settings on their smartphone or tablet to ensure a seamless user experience.

In addition to its technical specifications, DisparaTimer stands out due to its simplicity and adaptability. Whether you're a professional photographer or an enthusiast looking to enhance your darkroom skills, this application provides the tools necessary to refine your workflow. With its robust features and user-friendly interface, DisparaTimer simplifies the often-complex task of managing exposure times, making it an essential companion for anyone working with analog photography equipment.
