This circuit above is a cheap version stun gun circuit that is powered
by two AA baterry. The output of this electronic project is about 350V
dc. The heart of the circuit is the oscillator that is composed of Windings and transistor.

Primary winding P is composed of 16 turns of #24 AWG wire, feedback F is
composed of 8 turns of #24 AWG wire, and secondary winding S is
composed of 270 turns of #30 AWG magnetic wire. P1 is connected to the
collector of transistor, F2 to the 100-ohms resistor at transistor base. F1 and P2 to the battery. The output of Sec winding is rectified by Diode Bridge. The output capacitor is an electrolytic type that is rated 400V above. Capacitance
of the output capacitor depends on what available on hand, but always
keep in mind that the higher the value the better. this simple
electronic project is dangerous when accidentally touched, thus avoid
holding the output and discharge the capacitor before and after using.

One of the uses of this circuit is the camera flasher circuit.
