The ElectroMagnetic Potato is based off the premise of an electromagnetic pulse generator.  It uses the flash circuit from a disposable camera to generate a pulse of electricity.  This pulse flows through a coil of copper wire releasing a pulse of electromagnetic energy.  This energy slightly disrupts small electronics.  Other components of this project include a Mr. Potato Head, a switch, a 9v battery and an LED in the nose to show power.  In hindsight, I would've wired the LED to the charge light for the capacitor, but hey that is what MKII will be for!
