This is the Foxie CardClock, an open-source GPLv3, ESP8266-powered, WiFi-enabled, RTC-havin', super-capacitor havin', analog+digital, RGB LED-laden, clock.
In other words, it's really cool.
There are 2 rings of 12 LEDs at the top of the PCB, which are used as an analog clock displaying Hours, Minutes and Seconds. A 17x5 LED matrix also displays the time and allows for configuring settings. There's even a binary mode for the nerds among us.
A light sensor provides for a smooth experience in brighter and darker environments. Minimum and maximum brightness are also easily adjustable directly on the clock using the menu system.
The CardClock syncs NTP time once a minute from the WiFi connection. It also keeps track of time using the onboard Real-Time-Clock. Unplug your clock? No problem, the super-cap keeps the time for 2 days.
