 ## Producing my PCB
 
-Work in progress...
+I had to make a few modifications between the previous stage and
+production, as some improvements were made to the design, such as
+enlarging the traces, or adding capacitors to filter the signal at the inverter output.
+
+To produce the PCB, I need to export the file to gbr, using the export to
+manufacturing file function. A configuration window opens up, but I don't touch
+it much apart from the included layers. Here I only have the top copper layer
+(F.Cu) and the cutting cut (Edge.Cuts). I plot both files and also generate
+drill files.

+
+Then, as described in <a href="./weeklyassignments/week4/"> week 4</a>, I import
+the file into the Bantam software connected to the machine and mill the pcb.
+Unfortunately here, I forgot to make the holes with my drill files, but they're optional.
