As well as basic PCB making and soldering equipment you will need the following components:1x PIC16F628A & programmer1x DS1307 realtime clock chip1x 32.768kHz watch crystal3x BC548 (or similar) transistor2x ...
The first step is to make the PCBs, the PCB layout and schematics for the main clock and the display board are provided in Eagle format. The clock PCB is double sided, but the top layer consists simply of 7 links, this means that the PCB could also be made as a single layer with 7 wire links instead, this is the way I chose to make it as I cannot make double sided boards.
The display PCB uses exclusively surface mount devices while the main clock PCB uses a mixture of surface mount and through-hole components.
It is important to program the PIC chip with the hex file prior to soldering into the circuit as there are no ICSP connections on the board.
