Electronic photoelectric barriers are established devices to time subjects in experiments or athletes in sports. The systems are reliable and precise, but also expensive. 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. In two experiments with track and field athletes, we show that our novel system has similar accuracy than a professional photoelectric barrier system, but for a fraction of the costs.:1. Introduction
