 +When I was younger, my favorite arcade game was Operation Wolf. Unfortunately the NES version lacked some of the best details of the game. The NES zapper doesn’t feel like the machine gun in the arcade and the trigger will fatigue your fingers after constant fire. That is the reason I attempted this project. My hopes was to have a rapid fire option similar to the original lunar-rocker model. I wasn’t successful at the rapid fire but I was able to get some other nice options:
  
 +1. A more realistic look and feel.
 +2. The recoil action during fire
 +3. Extremely sensitive trigger (less fatigue under constant fire)

 +===== Material list: =====
 +
 +  - 1 SONY PLAYSTATION LUNAR ROCKER LIGHT GUN
 +  - 1 NES ZAPPER LIGHT GUN
 +  - 1 ROLL OF DOUBLE SIDDED TAPE
 +  - 1 TUBE OF SUPER GLUE
 +  - 2 PIECES OF FLAT LOW HEAT SOLDER (RADIO SHACK)
 +  - 9 VOLT BATTERY HOLDER.
 +  - 9 VOLT BATTERY
 +
 +===== Instructions:​ =====

 +
 +1. Remove all of the outer screws with a cross tip screwdriver and open the zapper (ill.1 & 2)
 +
 +
 +{{3-lunargun.gif|Light Sensor}}
 +
 +2. Unscrew the trigger assembly and remove the light sensor and trigger assembly from the zapper (ill. 2 & 3)
 +
 +
 +{{4-lunargun.gif|Sensor Disconnect}}
 +
 +3. Disconnect the two wires from the trigger assembly.

 +
 +4. Remove all of the outer screws with a cross tip screwdriver and open the lunar-rocker gun (ill. 6).
 +
 +
 +{{8-lunargun.gif|Circuit Board}}{{9-lunargun.gif|Trigger & Motor Mod}}
 +
 +5. Remove all of the contents of the gun except the rear circuit board, trigger, and motor. Cut the wires as close to the components that you are removing as possible.
 +
 +6. Connect the two wires from the NES light sensor to the two bottom wires from the circuit board inside the rocker gun (ill. 7 & 8).
 +
 +7. This is the difficult part. Place six pieces of double sided tape about an inch from the front. This will be a trial and error process. Place the light sensor on the tape and try to center it on the round lens. Connect the two halves of the gun but do not screw it together. Plug in a light gun game (operation wolf works good because you can see each shot’s impact). Aim, shoot and determine which direction the shot was off. Adjust the sensors position and repeat this process until the gun is shooting straight (ill. 7 & 8).
 +
 +8. The next step is to hook up the motor to the trigger for the “recoil” action. Place the double sided tape behind the sensor to hold the battery. Connect the red wire from the battery holder to one side of the motor. Wrap a piece of solder around the other wire of the motor and heat it with a lighter to hold it in place. Glue the metal solder to the bottom of the trigger. Wrap a piece of solder around the black wire of the battery holder and heat it with a lighter to hold it in place. Glue this solder to the contact surface of the trigger. (When the trigger is pulled it completes the circuit) see ill. 7 & 9.
 +
 +9. Connect the two halves of the gun together and have some fun!
