Whether or not it's easy is not very relevant.
What is relevant is that it is utterly pointless and this "genius" is not soldering anything on that picture.
It's not pointless. It's thrifty. It's what people who like electronics work do when the cost of replacing something is high and the cost of fixing it is negligible. It can be frustrating. It can take a fair amount of time. But a repaired PCB can work just as well as a new one, so why spend money needlessly?
I think you took this stance because you're looking for excuses to disparage the kid, not because you can't imagine why someone would take a soldering tool to a PCB.
And again, I saw that particular video, he is not soldering anything he is using it as a pointer and points to that big chip for some reasons. That board which looks like it is from old CD changer is a useless junk which can not be used for anything, you can salvage few discrete components and that's it.
This kid is a weirdo, he appears to be fascinated with electronics "porn" but this fascination is just all he has, he does not do anything meaningful with it. I mean when I was 6-7 I was fascinated with electronics too and by the age of 10 I was doing meaningful stuff, what this 14 year old does is bullshit.
Oh, so his interest in electronics is porn, and you started jacking off at the age of 6-7?
Thanks for the reminder not to take your posts seriously.
His "interest" in electronics is weird, and I explained why it is weird.
Because to you it's porn, which you started jacking off to when you were 6-7. You're right, that's weird.
He is collecting electronic junk without doing anything with it.
He built a pencil case clock with some of it, remember?
