Wii Camera and Easy PCB Etch How-To

Well, I got sick of having a lappy as a middle-man between my wiimote and my robot (via bluetooth). I decided to remove the camera itself and go with on-board i2c instead of sending BT data back and forth.

I decided to etch a PCB for the task using, I think, the easiest PCB etching process around. Period.
