Kyle pointed me to Adafruits Animated Snake Eyes. The software can be used withot any extra hardware. I had a spare Raspberry Pi 2, so I installed it. Pretty cool. Depending on your choises during installation, you can get either a single eye, or two.

 

 

 


Rasp Pi and a pair of Seeed ReSpeaker Mic Array V2

So I started a little Hack-A-Thon project over Thanksgiving. I initially was just connecting a single ReSpeaker Mic Array V.2 to a RaspPi running Ubuntu Mate and went through the tutorials. I also looked at a project called ODAS which had some pretty cool looking visualizations of Direction of Arrival and Angle of Arrival of detected sound. Unfortunately their visualization does not really run well on the PI. But... I am able to run part of the project on the PI and push the sound localization data to port on another computer. Also, I really don't need the visualizations.
