Figured I'd go ahead and post a picture of this, in its 99% complete state! I spent a ton of time working on this guy!
It's BTLE controlled from an android app, and has a number of display modes! Each tail spike can display pretty much any color I want, and I pre-programmed a number of display modes. The battery lasts for 14.5 hours of continuous usage!
First tail, but I feel like I did a decent job!
