This is an infinity mirror real time clock with date display, patterns and sleep mode. There is also an hourly melody played based on the UM66TXXL chip.
The real Time clock is based around the DS1307 chip.
An infinity mirror is 2 mirrors facing each other, one of which is a 2 way mirror for you to look in on the action, the light bounces back and forth creating an illusion the lights go on forever.
It is based around the very cheap and available RGB LED strips type WS2812B 3 wire addressable, that can be bought on ebay for a few dollars. The strip to buy is 60 RGB leds per meter. You need 1 meter. This is an ideal number for a clock of course.
