This weeks assignment was to add a button and a LED to the helloweEcho bord.

I added the components in eagle in the schematics view, placed them in the board view.

Here are the files

I exported the board view to *.png file. first the traces and then the border.

I generated a g-code in the fab moduls.

I etched the board in a sherline milling machine. The program we used is called EMC2. it reads *.ngc files so we changed the end of the g-code file manually (*.g to *.ngc).

Finally i stuffed the board with the components.
