Introduction: Christmas Party Earrings With Attiny85
Christmas party earrings with snowflakes effect on OLED display.
Parts: smd attiny85
smd capacitor 100nF
CR1625 battery (or CR1620)
I2C 0.91" 128x32 blue OLED LCD Display

Earrings are small, light and possible to be worn during party. CR1625 battery has sufficient capacity for running for about 5 hours and more - I have slowed down CPU frequency to 1MHz for that reason.
PCB is thin 0.6mm.
Program is made in Arduino IDE, is very simple and snowflakes are represented by asterisks for simplier code. Tiny4kOLED can be downloaded here: https://github.com/datacute/Tiny4kOLED .
