I purchased these a while back for a soldering class I was teaching.  It is a four digit alarm clock kit (24 hour clock).  It is fairly straight forward and should be easy for most beginning soldering students, and is a great learning tool.

I assembled a few of these and they are fun to assemble.  There is no tricky soldering anywhere on the circuit board.

The alarm clock displays the time of day, date, day of the week, and temperature (in C).  The automatic display function first displays the time for 45 seconds, then temperature for five seconds, date for five second, and lastly the day of the week for five seconds.  Then it starts all over again.

Please look at ALL the pictures.  The components and circuit board are shown along with a circuit board with all the components installed.  Please make sure the kit is within your capabilities of assembly.

Also, please review the assembly instructions which are located here:  http://www.diyleyuan.com/wenzhang/01E.html
