This is an amazing clock project! Assembling all the parts takes about 1/2 hour with a mediocre soldering experience. The DS1302 RTC chip comes in an SMD package; assembling it will need 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, an 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 choose from, and they can be switched 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 an external power source due to a small backup battery*.

With a photoresistor 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 a 5V power supply, for example from a phone charge or USB port.

The included manual is in Chinese, but schematics are the same in any language and you will easily find out how to assemble it. 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 no need for additional assembly instructions. The functions are easy to find out using the 2 buttons on the back. The clock looks amazing when placed behind a semi-transparent mirror or tinted acrylic!

Please have a look at this Clock Case designed by Philip Schwartz.

*1 x CR 1220 battery is required for timekeeping without a power supply
