ok well here is my input on this thread.
This was when i was a total noob at everything, i knew a little about soldering, so i go and am about to install my modchip, i have all of my materials ready, so i go and plug my solding iron in and i wait like a minute and bring the iron up toward my lips to see if it is hot, (friends idea) well not hot enough, so i wait a little longer and this next time i get a little to close, and yea, never get to install that modchip that night.
Here is another, i just connected the psu to the mb to test some leds, didn't place them in the case, well i connect the power cord and i test the leds, and everything is to my liking, so i go to disconect the cord from the psu, and i start tugging on the cord with my left hand and try not to touch anything with my right which is holding the psu, but it doesn't quite work and i get shocked, and stupid of me doesn't learn i do it again.
