Simple Sensor Circuit for High Speed Bullet Photography
The following video tutorial details the creating of a simple transistor based circuit to detect the impact of a bullet and fire a strobe light for photographing bullets in flight.
Current is applied to the base of the transistor via a piezo transducer, which closes the circuit triggering the flash. Modifications are made to provide an increased and variable sensitivity and then the setup is tested by firing bullets through various objects placed on the sensor.
