It is a Tiki PCB Badge. It has an Attiny85, controlling over i2c an MCP23017 which then drives the LEDs, it is all powered off of one cr2032 battery (NOT included).
The code is using the watchdog timer with different periods to setup different blink mode timing. In the code linked via GitHub, there are the examples with how it is done as well as how long each period is (if you are going to reprogram yourself this will be useful) keep in mind the longer the lights are on for each mode the shorter the batteries will last. Blinking is the longest lasting as well as only having a couple on at a time.
There are a few modes, which can either cycle through (MOUTH ON WHEN POWERED) or repeat (EYES ON WHEN POWERED). If you power cycle it will toggle between cycling and repeating, saving which mode it was currently displaying.
This project was brought on by my love of tikis, tiki drinks, tiki culture and also making a few tikis out of ceramics.
There is specific code to have the eyes lit and to look like a flame is flickering in its mouth. The PCB is shaped to look like a tiki head with an attachment for a lanyard. It also has a SAO connector that is version 1.69bis compatible (the connector takes up a large portion of his forehead, so I went with the v1.0 2x2 header).
