The Adafruit crew likes their Wolves and Dragons, even when they are parodied by frequent Maker caitlinsdad. He has posted on Instructables a project on making a werewolf-themed backpack. What makes this extra RAWR is using an Adafruit Circuit Playground Express to drive a servo tail and blinky NeoPixels.

He writes:

The Adafruit Circuit Playground Express board has lately become my go-to board for prototyping really quickly. Using CircuitPython and the Mu Editor, I can adjust code to make things work as I go along.

Taking inspiration from the Adafruit Really Simple Animatronic Tail project, I learned that you should use a piece of aquarium air line tubing for the tail to give it that fluid tail-like motion.

The Circuit Playground Express board is also capable of playing small sound clips. I found a howling wolf .wav file I liked. There was not enough room on the board’s memory to load the sound file. I used Audacity to downsample the sound clip to a low 16khz.

Version 2 features being considered are a Full moon detector and water bottle holder.

Check out the full details, build, and programming over on Instructables.
