The Lego Wii Zapper is a Wii controller gun attachment made completely out of Technic Lego.
Most of the buttons are operated by Lego parts except for the power button and the D-pad.
About this creation
The problem I find with all the Wii gun attachments is that they make it so you only have access to the “B” button and not much else. So I designed my own Wii gun and made it so has two trigger buttons, the “A” and “B”. The other buttons also work but are harder to reach and the “1” & “2” buttons don’t responded too well. I may make a better version it the future.
The Lego Wii Zapper itself responds very well and I have yet to have a problem with the triggers not working. The game it works best with, that I’ve tried it with, is Super Mario Galaxy, mostly because you don’t really need to access the D-pad or the + & - buttons that much.
