Can anyone give me an exact (or very, very close) measurement of the surface of all x number of soldering points? I just got a soldering iron and i want to practice by replicating small points about that size and applying solder before I open my wii. Can anyone tell me how many points I should be prepared to be and how big they are? (Dimensions in mm please) I got puny wire (from a USB cable) so i think i'm good there. I plan to make a serial port in the back like Scorpei did.
