From the Forums: Skeleton crows with red, blinky eyes #ItsyBitsy #Adafruit #Halloween @Adafruit
Adafruit Forums user MitchellJThomas posts about adding glowing eyes to skeleton crows for Halloween.
Idea: A murder of skeleton grows hangs in the pine trees staring at you with glowing red eyes blinking every so often
1. both red eyes blink every so often on a 10 minute loop (long enough for someone to stare at them for a bit and then move on)
2. each crow is self powered for at least 6 hours
3. electronics budget for each crow is less than $20
The build consists of an Adafruit ItsyBitsy 32U4 microcontroller board, battery pack, and red LEDs for the eyes.
The result (see picture above):
A photo of 5 of the 9 total crows. It took a bit of doing but they survived rain, wind and succeeded in adding a creepy effect to the trees in the front yard on Halloween night.
