A lot of the DIY projects we feature require soldering, which unlike soldiering, doesn't usually involve loss of life, but is still painful as crap. Instructables has a guide on soldering for beginners, which is totally useful if you didn't spend a semester soldering your fingers together because your female lab partner didn't know what she was doing (but managed to help you through the "math" part of the class).
