After quite a bit of testing, I was able to make a unique A button for the zapper gun. I've decided on a metroid theme (big surprise) and the A button will be a custom metroid one as shown here. I plan to make a guide on this in the near future, for anyone interested
The main body of the gun will look like this. I did some practicing with this wiimote to get a scuffed metal look. The grey is "oil rubbed bronze" and the silver is metallic silver, both Rustoleum for plastics. I'm going to use a higher quality top coat for a nicer feel though.
Here is the main body drying after the first color. Tomorrow I can get on with the next colors
I'm considering some orange accents. You can see that I added three new holes to the right of the dpad. One for sync, one for the power button, and one for a green power led.
So, since I'm rather attached to the idea of it being scuffed metal colors, but also with a metroid theme, I was left with mainly these two pieces to make it clear that it's a metroid controller. You can see that I have two stripes on each of them dremelled out.
The reason for the stripes is that I'm going to paint it like Samus's arm cannon. I'm going to use the clear plastic piece from the Wii's faceplate to give it the yellow glowing stripes. They will likely be behind the plastic gun piece instead of embedded in it, but if I can figure out how to light it properly with it embedded, I will. To keep the light from spilling out and diffusing, I'll be using my aluminum tape to keep it in the clear parts. I've already tested and it lights up well.
I hope to have this done by the day after tomorrow, but you never know
I also realized that I'll have to make a matching nunchuck, but I'll wait until it's finished I think
