After a lot of head scratching, frustration, and failed revisions, we've decided to get rid of the Nerf idea. There simply isn't enough space inside the gun to make this idea work.
We've instead decided to come up with an Arduino-operated ping-pong ball launcher. The only part we're going to need to source is a launching mechanism, the rest will be fashioned in SolidWorks and coded with Arduino.
Since we've changed our idea a few times by this point, we decided it'd probably be a good idea to post the SolidWorks model of the launcher housing that Trevor has mocked up. This shell will be modified accordingly to fit the launcher we end up choosing.
This is the isometric view of the part as it currently stands:
And this is the view from behind. The launcher will be inserted into the rectangular bay, oriented out the chute.
With any luck we'll be able to rig our launcher to a simple Arduino push-button launching system. With a lot of luck, we'll be able to do something really cool, like have it rotate on a base, or fire automatically from a gravity-fed hopper. Stay tuned!
