Before my 3D printer went down I managed to print out ( a while ago ) one of Perry's designed eyepods assembles.
While I'm waiting for parts for the dual extruder head assembly, I decided to see if I could get the EZ-B IoTiny to control the Neopixel via the Ardiuno Nano using the recently re-posted old tutorial of David Cochran NeoPixel Ring with Arduino Nano as the control board.
The Arduino sketch is a bit buggy? but I managed to get it working OK.
It works quite well, created a simple script to control the two servos and the Serial commands for the Ardiuno to run the Neopixel.
I used two Corona DS339MG servos, which were of similar size to the Hitech HS-225MG Perry used in his design, but a lot cheaper!
BUT for some reason the iris ( White ring ) doesn't show it changes colour when Videoing, but when you view it normally the whole iris ( white ring )
changes colour. I've used my iPhone and a video camera to video it, also changed the intensity of the Neopixel via script control, videoed it in light and dark conditions, but it makes no difference??
I would like to thank Perry for his design and 3D stl files of the Eyepod, its been great fun and challenging putting the eyepod together!!
