If you don't want to build the controller yourself, you can buy a High Speed Photography Kit that was developed by the authors.

+ Discharging the Capacitor

Before you take apart a single-use camera, you need to know that there is a large electrolytic capacitor inside the camera. See the instructions in MAKE 04, pages 109 and 110, for how to disassemble the camera. This video shows you what to expect.

+ Industrial Strobe Demonstration

Industrial strobe lights are used for inspection of machinery because they can freeze moving parts.
