Well, have you ever soldered a 40 pin IC backwards?? And this was before having a nice desolder station. Finally, after a lot of time and lifting several traces, I installed a socket, just in case, reinstalled the IC and all was fine. However, had I not used a socket, I am convinced the IC would have been dead. I'll not confess to whether or not I powered the board on with the IC installed vastly incorrectly.
I'm not sure I ever installed a 40 pin DIP backwards, but I've certainly done it with smaller ones - and once with a 15,000 µF electrolytic that set off the smoke alarm when it exploded.
Trying to get there! I need a current mirror for the next step, and I need to invoke Ebers-Moll to explain how a current mirror works - and that needs more background on transistors. The rabbit hole goes deep!
I was probing signals on an AC radio once with my scope and forgot to use my isolation transformer. I actually blew and changed the fuse in my variac once before I blew it again along with a very large trace that left a copper stain on the bench. Luckily the fused variac saved the scope and no-one was hurt and I was able to fix the trace and the radio.
I was once, back around 1978, making a quick-and-dirty change to a Wire-Wrap backplane of a mainframe computer, with the power on. (Yeah, we field service techs were kind of cowboys.) I slipped and caught the5 volt busbar with the bit of the Wire-Wrap gun, The bit melted in half immediately, with a huge shower of sparks. The computer didn't even crash.
This is why I say sometimes learning cost more then paying people but we never learn if we don’t try
I've wrecked my share of stuff on jobs I was being paid to do. It happens.

Being stupid is the joy life, looking forward towards your next tri osc. video. My best wishes for your YT journey.

@@KludgesFromKevinsCave If some sign that could bear witness on a journey worthwhile, plodding eventfulness was certainly not it :)

Been there, done that.
Oops 😂
