I used Eagle to modify the circuit adding a button and a led following the tutorial, I also modified the routed of the traces and make chamfers on the corners.
I make the cut file with gimp
After milling and cutting the board on the modela I used soldering paste to solder the components.
Instead of the on-board button and led, I put a couple of connectors to can take the button and the led out of the board, and to can change, for example, the button for a photocell or another kind of switch.
This is the
final aspect of my board with the button and the led connected.
