A Special Thanks to Colin. For helping me with the WebCam calibration concept way back when.
Visit my blog, for all other details not contained in this instructable.
Update: HACK-A-DAY Post checking out the turret. Very flattered from these guys words.
Step 1: Get an "Electronic" Airsoft BB Gun. And Slice it open.
If you are in the U.S. Say just as the title says, go to any Department Store and buy one.
Look for guns that look easy to cut or to take apart.
After you've got your gun, open it up (follow this guide).
As you can see, it is very simple. If you power the motor, you fire the pistol. Before you hack it open you do this by closing the circuit by pushing a switch with your finger as you pull the trigger. But there are many, many ways to close an electric circuit, and you can get very creative. In this project we are going to use Relays to do that.
If you are not in the U.S, this may take some doing.
I am obviously not in the U.S. but I got Lucky. A friend of mine gave me his.

If you are in Mexico: 'jalense a los bazares o a los mercados y busquen a la gente que vende cuchillos y pistolas tipo militar. las tiendas de chucherias afuera de los super mercados (Soriana y la Comer y demas) a veces las tienen. De ultimas, preguntenle a algun amigo que le gusten las gotchas si tiene una o sabe donde comprarla. En Mexico es comun que vendan gotchas y Airsoft Guns en las mismas tiendas.'
