I had the most unbelievable sense of accomplishment yesterday, because I got a mod chip installed and working on an OLED model switch. But looking back at the tools and things I bought, I must have spent $900 or so ($470 because of a major fuck up... $350 switch and $120 mod chip).
I completely fried my first attempt. Mistake after mistake with a cheap and inadequate microscope, and at the end I flushed a sliver or two of solder wick out from under the x1 chip. So I'm pretty sure I fried it. Doesn't turn on. Also made a mess with solder mask that came with a weak-ass uv light for curing... and I had no experience with how it was supposed to cure and how to tell if it was cured enough.
Anyway, the hardest soldering I had done before this was hard-modding my n3ds, which unironically, I also took 2 tries on. I broke the clk via by ripping the pad off and was successful on my second try.
Anyway, the cmd and clk lines for the OLED switch are on a 0204 resistor and an even smaller point that is both covered with mask, and underneath the frame for the cpu heat shield cover.
This video makes it look so easy! It's not. I wish I had the kind of tip this dude is using, but it's for a specific kind of soldering station that's like $230 or so, and the tips are like ~$18 a piece... https://youtu.be/sSBdltReQkg
Just broke my personal record for number of consecutive days without dying!
