This is an amazing clock project! Assembling all the parts takes about 1/2 hour with mediocre soldering experience. The DS1302 RTC chip comes in an SMD package; assembling it will needs a steady hand.

The clock comes with multiple functions, like Date, Time and Temperature (F or C), has an Alarm Function with different Alarm Sounds to choose from, optional hourly chime function, and a ring of 60 LEDs to show the current second with different light effects.

There are 13 different displays to chose from, and they can be switch automatically by setting a timer function (once per hour, for example).

The real time clock chip DS1302 has an accuracy of about 0.5-2 minutes per month and keeps the current time also without external power source due to a small backup battery*.

With a photo resistor on-board, the display brightness can adjust automatically to the environment. The brightness can also be adjusted manually.

A Mini-USB port is used for 5V power supply, for example from a phone charge or USB port.

The included manual is in Chinese, but an English troubleshooting guide is available online (follow the QR code on the included instructions). Since all parts are clearly named on the PCB, and the instruction sheet shows the exact part name and value for every part, there is absolutely no need for more assembling documentation. The functions are easy to find out using the 2 buttons on the back. The clock looks amazon when placed behind a semi-transparent mirror or tinted acrylic!

*1 x CR 1220 battery is required for time keeping without power supply
