Sans - Undertale
This build started as a oil clay sculpt, molded in platinum cure silicone. Cast urethane resin as it's base, Sans consists of tinted PETG lenses, OLED screens, and black mesh venting.
The gloves were a combination of hand painting and airbrushing on a white nylon base.
Each expression is controlled by small momentary switches located at each fingertip of the right glove. Powered by an Arduino Teensy 3.2, the electronics are housed in a discrete enclosed backpack. For temperature control, two fans are located at the corners of either side of the mouth.
