Nintendo Wii Fanboy blog has posted a bunch of really cool Nintendo Wii Zappers you can make.
Let me go through them for ya:
The Lego Zapper is really cool but I am not sure if it’s practical, you can check out the mod page here.
Here’s AK47 Nintendo Wii Zapper for all you shooting-freaks.
Here’s a Nintendo-retro REAL Zapper that uses NES Zapper. (You need to register to see content)
Here’s a cool Clear Pistol Gun Zapper, I personally like this one the best since it’s small yet versatile.
Here’s cereal box Zapper, it’s a great way to recycle too so we are giving this guy the “Zedomax Eco-Zapper Award”.
