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. Now, I have seen a lot of great "adapters" to go from the fine pitch of the wiicamera pins to "standard" pin spacing, but I need not only to adapt the pins, but also a good way to mount the device to the pan and tilt mechanism I have on Walter. I decided to etch a PCB for the task using, I think, the easiest PCB etching process around. Period.
