4 Watt fluorescent lamp powered by AA battery

For this project you will need a disposable camera. Why a disposable camera ? Because the flash circuit inside the camera contains a hi-voltage oscillator and transformer that outputs about 300 Volts AC & DC. When opening the camera to get to the flash circuit you should be extremely careful so you don’t get electrocuted by the high voltage’s inside the capacitor. First thing you need to do is to discharge the capacitor so its more safer to work with. Then with a small modification into the existing circuit you’re ready to power the 4 watt fluorescent lamp
