For the flashlight after we made the design we had to cut our wires. The way to cut your wires and make sure it is the right size is that when you make your design you draw the wires so you put the wires that you are cutting and a line it with your design and then you measure the wire that you cut but you have to add a extra inch to the wire. It was pretty hard for me because it was hard to a line it and make sure it is prefect and it took me about 3 – 4 days which is a long time. All in all I think that it was hard but it was still fun
