Our work contest this year was to decorate a mini stocking. I
chose to add lights and music using Adafruit parts. The lights are
individual NeoPixel LEDs, the audio comes out of a mini speaker
(https://www.adafruit.com/products/1890) driven by a 2.5W Mono Amp
(https://www.adafruit.com/products/2130). The smarts of the stocking is a
Teensy board (https://www.adafruit.com/products/2756) running the OctoWS2811
library for the LEDs, the Audio library for the music (DAC output to the
amp), and the Snooze library (with one pin setup for capacitive touch
wake-up) for power savings. A 3xAAA battery pack was used for power. I
thought it turned out really great and it looks super cute.
