Airsoft Gun Hack

I’ve searched for Arduino operated electric airsoft guns and nothing really stood out to me. Does anyone have any links to a good site or just some good ideas on what to make or what to apply it too? Anything at all will help, also i’m not really planning on making anything out of it, I just want to understand/get a good idea on what it would look like…if that makes any sense.

Something like this? http://www.youtube.com/watch?v=-eAol3mhZas

You could add a robot base and aiming servos but only you know what you want to accomplish.

Sweet, helped a lot thanks!
