Mask with Raspi Eyes

thingiverse

This was a fun project and I think the end result was rather creepy. I'm considering what to add next, but some moving teeth are a real possibility. Anyway, I used the Raspberry Pi Zero with the Adafruit Snake Eyes bonnet and dual 1.5" color OLEDs. See some details at https://learn.adafruit.com/animated-snake-eyes-bonnet-for-raspberry-pi Many thanks to Cporto for the Low Poly Mask design. Retained the OLEDs using a slightly modified version of the Teensy OLED sandwich mounting. I added a cutout for the top mounted cable pin/socket to exit on the rear piece of the sandwich (Face Backplate). Source files for the original OLED sandwich parts are at: http://www.thingiverse.com/thing:1002413 and lots of helpful text is at: https://learn.adafruit.com/animated-electronic-eyes-using-teensy-3-1/3d-printing . Many thanks to Pburgess for the original OLED sandwich designs. I designed a standoff mounting bracket (EyeMount) that positions the OLED sandwich behind each eye on the mask's interior. The two EyeMount standoff pieces are L&R mirrors of each other. Each Teensy OLED mounting sandwich pair is screwed onto its custom L&R EyeMount standoff bracket using four 2.5mm machine screws threaded directly into the EyeMount standoff post's center holes. No 2.5mm nuts were used, I force threaded the mounting screws right into the EyeMount's plastic. The last step was to glue the four standoff mounting points of each fully assembled eye onto the interior of the mask using a Bondic type, UV activated adhesive material. I used the Bondic stuff because it is a thick, viscous, gel-like material before it is cured, and can be easily built up in layers for additional strength. A quick zap with the UV LED solidifies it almost instantly, and made the holding-things-precariously-in-place-while-gluing-down process somewhat easier. See finished pix of the glued-in eye assemblies on the interior of the mask.
