Single-use cameras are largely plastic shells around 35-millimeter film canisters, with mechanisms to expose and advance the film. Many have strobe flash circuits built in that synchronize with the shutter, providing additional exposure in low-light settings. The circuit board controlling the flash is remarkably versatile, capable of re-work into a number of projects.
Photographic Uses
The circuit board controlling the flash allows a 1.5-volt battery to charge a capacitor that discharges in synchronization with the shutter of the disposable camera. Using alternate sources to provide firing information, you can create high-speed photography devices using sound triggers. Wiring several flashboards together and arranging them around the lens of a regular camera gives a low-cost ring flash for product and macro photography. You can supplement regular cameras with on-board flashes by building slave units from the flashboards.
Coil Launcher
The principle behind the flash board takes the small and manageable voltage of an AA battery and stores it in a capacitor, where it builds to many times the initial 1.5 volts before being suddenly discharged to operate the strobe flash. This store-and-release principle can be applied to a small electromagnetic launcher as an experiment. One example of such a project uses capacitors from four disposable cameras to provide a current pulse of about 400 amps into an electromagnetic coil.
Tazer
Removing the capacitor from the flashboard isolates a transformer and transistor. These components raise battery voltage in the flashboard for storage in the capacitor. Rearranging these components can use the power amplification process to create a taser capable of delivering more than 300 volts. While this will not produce enough taser effect to do more than startle a victim, it does demonstrate how electricity from a single battery can be stepped up.
Fluorescent Flashlight
A more practical use of voltage step-up starts a fluorescent light bulb glowing. The flashboard provides the basis for a circuit that delivers the initial surge to turn on the bulb, as well as the maintenance charge that keeps the bulb lit, exciting the fluorescing gas within the tubes. Adding a switch and constructing a shell to house your components will result in an inexpensive do-it-yourself flashlight.
