To update the firmware on your clock you'll need either an AVR programmer (such as a USBtinyISP or STK500 or AVRISP, etc) or an FTDI cable (which allows you to upload via the onboard bootloader.
To do so, first download the firmware (click on Download Source in GitHub). Then install an AVR toolchain. Then go to the firmware directory using a terminal (such as the DOS command line, Terminal for MacOS X or xterm) and type in make to build the .hex. Attach the programmer to tbe back of the kit via the 6 pin cable so that the red wire is at the top. You can use the left-over 6-pin connector and just 'press fit' it, tilting a little to make good contact. If you have a USBtinyISP you can then just type in make program and hit return. If you have another AVR programmer, edit the makefile to change the programmer and port to whatever you've got.
There's also a fresh version of the firmware, much cleaned up and easier to develop with than my code ;)
