Instructions
Find a gun you want to use. You can use a large plastic gun from a store, an old Nintendo pistol used for "Duck Hunt" or any other gun. Some people have made this modification with a metal gun for a more realistic feel.
Take off the battery cover and remove the batteries from a Wii remote. Remove screws and gently pry the remote apart to reveal the circuit board.
Use a marker to show the left and right side of the infrared sensor on the board so you know in what order the pins are located on the system board.
Remove the infrared sensor from the end of the circuit board. Very carefully, use the soldering iron on the solder points for the sensor to release it from the board. Set the sensor to the side.
Cut the wire into eight equal lengths. You can make the wires 2 to 3 feet long so you can hold the Wii-mote in your non-shooting hand. Mark the ends of your wires to keep them separate. You can use simple dots or color code the wire ends.
Run one end of each wire into the Wii-mote through the hole created by the missing sensor. Solder each wire into place where the pins were attached to the board. Make sure you don't bridge any connections with the solder.
Solder the other end of the wires to the infrared sensor in the same pattern as when the sensor was attached to the board. Follow the marks you made earlier to attach the wires to the appropriate posts. You are basically extending the connection from the PCB to the sensor.
Test the controller by turning on the Wii and pointing the sensor at the screen. If the sensor doesn't work properly, make corrections to your wiring and solder.
Run wire for the "B" button on the controller, like you did for the sensor. You will connect this wire to the trigger on your gun so that when you pull the trigger, it sends the signal to the Wii. Using the NES gun makes it easier to connect the trigger.
Take apart your gun.
Position the infrared sensor at the end of the gun and set up the wiring for the trigger. Don't finalize the system yet--just get the wires and sensor in place and ready to use.
Protect your wires by wrapping them with the electrical tape, or for a smoother finish, use wire shrink wrap.
Hot glue the sensor to the end of the gun's barrel, connect the trigger wire and assemble the gun. You should be able to use the buttons on the Wii-mote to sort through weapons and give commands with one hand while you shoot with the other.
