DIY shutter speed tester construction guide using readily available components: two BPW 40 phototransistors, 5 kOhm resistor, stereo jack input, and 1.5V battery. Includes complete circuit diagram and step-by-step assembly instructions. The guide details phototransistor placement along the 24×36 frame diagonal to capture precise shutter timing data, then walks you through pairing the device with standard audio recording software and analyzing waveforms in a waveform editor. Results table and performance graph show real-world measurements taken on a Pentacon FB camera, providing practical reference data for validating shutter accuracy across different speeds.
