The Internet Of Seashells is here! I was able to complete the first seashell before Christmas. Unfortunately, in order to preserve the secrecy of the project I didn't keep a careful build log, but I will share what I learned. I started off with an Adafruit Feather HUZZAH with 500mah LiPo battery, Adafruit's VS1053 breakout board, a cheap battery-powered speaker unit, and my seashell. At the moment, the program I am using is the Karawin Ka-Radio with the web front end (no hardware panel). That project is also hosted on Hackaday at https://hackaday.io/project/11570-wifi-webradio-with-esp8266-and-vs1053
