Starting today, "Wise Clock 2 complete kit" has the ATmega644P microcontroller loaded with the latest version of the "Wise Clock 2" software (this is on top of the bootloader, of course). This means that after assembling it, there is no need for ATmega644P chip to be programmed anymore; this eliminates the need for FTDI cable, Arduino IDE, code download, compilation, upload, and greatly simplifies the construction of the clock. (Obviously, the software can be changed/upgraded any time through the FTDI connector).
Price for the kit remains the same, US$84, with free shipping (only to North America). Buy it here.
