<br> <b> <font size="5"> PCB milling and waterjet cutting </font> </b> <font size="4"> We did not receive a formal homework assignment this week, so I used this page to summarize the lesson. <br> <br> During the assignment we talked about PCB manufacturing. It included to mill custom boards with PCB. Furthermore, we had a workshop on the corresponding CAD software for PCB design, called fusion 360 Eagle. It helps to bring the electronic inventions to life. I designed a circuitboard with some wire routing and some capacitors just to learn the basics of the software. <br> <br> After that we talked about the water jet cutter. To me, it was highly interesting to see this industrial tool being capable of cutting different materials using an extremely high-pressure jet of water. Thinner materials can be sheet-bent (including metal) as well. After that you can use a spot welder to let electricity flow through material, acting like a resistor and heating up, and the heat welds the two parts together. <br> <br> I helped Joshua with his final project as we cut the brackets for his stepper-motors for the wall with the water cutter. It worked very precisely! <br> Here you can watch the corresponding video: <br> <video width="600" height="380" controls> <source src="IMG_6412.MOV" type="video/mp4"> </video>
