Ok, here's Part II
Wii Sight Mk III
You may have to click on the picture to enlarge it and really understand what is on there. Basically there are two different versions to this design. The whole purpose for this sight was to eliminate the awkward hand position that is present in the Wii Zapper as well as other Wii remote shells on the market right now. Instead of having the left hand in the back like on the zapper, it will be on the front grasping the nunchuck as if it were a foregrip in the regular, familiar fashion that a firearm would be held.
The only difference between the two versions is the different designs to accommodate the Nunchuck. A trigger will be wired to a grip in the back using parts that I already have in my possession. (I don't have to worry about this part). The wire connected to the wii remote would be slung over the right side of the shell and connected to the nunchuk and out of the way.
The shell itself would be made out of PVC, probably 1 inch OD or larger for the better part of the body. Some of the things I like about this design is the hand position problem being solved as well as the addition of a removable stock. It would be made entirely out of 3/4 PVC inserted into a 3/4 coupler so that it can be removed.
One of the draw backs would be the buttons on the face would be harder to access since they are up top. The design can be altered to shorten reach by shortening the body itself. It will definitely be larger than the Zapper but think that's part of the give and take. It'll be comfort over size.
