I tried to fix the cracking hinge in my 3ds xl and I wasnt able to get that far since I stripped the screws.
I ended up killing a laptop when I opened it.
I tried to open up my gbasp and stripped the screws so I cant open it now.
I tried using a weed wacker one time and it wouldnt turn on and I realised it didnt have any oil in it so I found a bottle of oil and poured the whole thing into it. I tried using it again and it didnt turn on and showed a neighbour and he asked me how much oil did put in it. I told him all of it. I learn’t that day you not supposed use that much. I broke it. lol
I also tried opening up a different laptop and stripped its screws as well so it cant be opened.
I also tried opening up a portable dvd player battery and luckily a neighbour stopped me. I could of electrocuted myself they told me.
In high school I turned on a soldiering iron and it broke instantly. It made this popping noise and it had this awful smell. It freaked me out so bad that Im now too terrified to ever use another soldiering iron ever again. I tried again in college and it ended up freaking me out too much and I got laughed at.
I also stripped many screws on game carts before I got the correct tool to open them. I used a knife and cut myself the first time. I also tried using two knifes one time(Im clearly an idiot and should stick to just using stuff and not opening things). I dont recommend using a knife ever for that purpose.
I also destoyed a tamagotchi by opening it up. I never got it back together sadly.
I dont open or repair things anymore.
