i just spent like 90 minutes putting 6 wires through 6 holes and only the final two just worked, and i have no clue why. all the others melted in my hand at some point. the majority of the time was spent failing to put a wire through a hole that had already been soldered (and removed, because the two wires that were (supposed to be) next to each other melted together so much they were a dead short) and its just impossible to do that, regardless of position in time or the configuration space. i managed to somehow (a) char and (b) cut straight through the solder mask (iron at 300) during this. top 10 worst time
