Eye Of Ionytrix

The eye of Ionytrix, Farore Nightclaw's wonderful latex hive-mind coyote.
I created this as a birthday present for zir, and I'm open sourcing it so that others can make their own!
Io's eyes are made of LEDs which spin and blink in patterns, I hear it's quite hypnotic. When I first saw the picture of Io tearing one of its eyes out to get a better look at it I wondered if the blinking would continue outside of its body. I guess it does! @_@

Using white plastic, print out one copy of EyeOfIonytrix_v6.stl and glue 8 blue LEDs into the holes, making sure the LED's casing falls fully below the top of the model. Solder the LED's anodes together into a ring to create a common ground for attaching to the ribbon cable.
Again, using white plastic, print out either one copy of EyeOfIonytrix_p2_v2.stl or EyeOfIonytrix_p2_v1.stl depending on if you want the eye to be filled in or hollow respectively. (A hollow eye could possibly be used in the future to create a costume.) Reduce the ribbon cable to 9 pins and thread it through the slot in the side of either model. Separate and strip the individual cables, connecting one to the common ground and the others to the cathode of each LED. The other side of the ribbon cable will connect to the digital out and ground pins of an arduino.
Tweak the code contained in EyeOfIonytrix_v2.pde so that the digital out pins connected to the cables connected to the LEDs will be turned on in a sequential order by the program and upload it to your arduino.
Optionally you can attach any kind of white wire or tubes to the holes in the back of EyeOfIonytrix_p2_v2.stl or EyeOfIonytrix_p2_v1.stl to create an "optic nerve" coming out of the back of the eye.
Use glue to secure the ribbon cable from pulling out and then firmly glue the two printed models together to protect the electric connections inside. Fashion a light diffuser out of semi-opaque paper, plastic or frosted glass and glue it onto the front face of the model, hiding the LEDs such that they will only become visible when illuminated.
When you turn on the arduino the eye should light up in a theater-marquee style chaser pattern, moving either clockwise or anticlockwise depending on the order the program's variables have been assigned to digital out pins. If the LEDs light up in a random order, further tweak the variable assignments so that the proper sequence is displayed.
Finally, stare deeply into the eye and listen to its commands, Io means you no harm. It is useful to obey the eye.
