I added the 2 PDF I used to build the circuit on a 24x18 perfboard. There is one file for the top layer, and another file for the bottom layer.
Usually, I print the 2 files at 1:1 scale, and simply follow the drawings. This time, I glued the top layer drawing on the perfboard prior to routing, so it was very easy and gives a nicer look.
Here is the view of the PCB in DesignSpark. It is a 2 sides PCB with large traces, so it should be very easy to manufacture.
