Abstract
Electronic photoelectric barriers are established devices to time subjects in experiments or athletes in sports. The systems are expensive but also dependable and precise. We propose a novel, affordable photoelectric barrier system based on consumer grade camera hardware and show how to build such a system with common electronic components and a smartphone. We demonstrate in two experiments with track and field athletes that our novel system has accuracy comparable to a professional photoelectric barrier system, but for a fraction of the costs.
