Currently trying to figure out how to control servos and such to move the ears and mouth on my future Toothless costume. A month ago I wouldn't have been able to tell you anything about servos, potentiometers, pull-down resistors and the like, but now they consume my thoughts.
Cosplays for Naka-kon 2015 and Planet Comicon 2015:
Toothless (with animatronics) - HTTYD2
Amethyst - Steven Universe
