A stun gun can be a useful defensive weapon if you are attacked by an intruder who has broken into your home. You can make a stun gun from household items that most people have lying around. You will also need a disposable flash camera purchased from a hobby store or drugstore and experience with using a soldering iron. Your stun gun should only be used if the situation warrants it and definitely should not be taken out of the confines of your home.

Place a disposable flash camera on a work surface with the lens facing up. Remove the screws from the front top left and right corners and the lower left and right corners using the Phillips screwdriver.
Unscrew the lens ring from off the lens. Remove the screw from the bottom of the camera using the Phillips screwdriver.
Pull the front shell of the camera off the back shell. Snip the wire connecting the two shells with the wire cutters. Dispose of the front shell properly.
Remove the battery from the battery compartment on the back shell with your fingers. Place the battery aside. Remove the film cartridge that is next to the battery compartment with your fingers. Dispose of the film cartridge properly.
Remove the screws surrounding the circuit board that is on the back shell with the Phillips jeweller’s screwdriver. Pull the circuit board off the back shell. Dispose of the back shell properly.
Place the circuit board on the work surface so that the silver cylinder is on the left side.
Heat up the soldering iron. Cut two 10-inch lengths of electric wire with the wire cutters. Strip a half inch of insulation off each end of both electric wires with the wire strippers.
Solder one of the ends of one of the electric wires to the Positive (+) labelled contact that is at the top of the silver cylinder. Let the solder cool for a minute. Solder one of the ends of the other electric wire to the Negative (-) labelled contact that is at the top of the silver cylinder. Let the solder cool for a minute.
Wind the free end of one of the electric wires around the head of one of the two metal nails. Apply a drop of solder to secure the end of the electric wire to the head of the nail. Repeat this procedure with the free end of the other electric wire and the other metal nail. Let the solder cool for two minutes. Unplug the soldering iron.
Place the ruler horizontally on the work surface. Place bonding glue on the top of the left end of the ruler. Place one of the two metal nails on the left end of the ruler horizontally, so that the point is halfway off the end. Place the other metal nail a 1/2 inch away from the first on the top end of the ruler in the same position. The nails will stick up over the short edge of the ruler like antennas. Let the bonding glue set for three hours.
Apply bonding glue to the top of the ruler at its centre. Place the bottom of the circuit board against the top of the ruler where the bonding glue has been applied. Let the bonding glue set for three hours.
Place the battery back into the battery compartment. Wind the knurled wheel on the circuit board to power up your stun gun. Place the points of the two nails against an intruder and press the shutter button on the circuit board to release the electrical charge from your stun gun.
