Look, I like to build stuff. I'm on a tight budget, so that means my stuff is built from parts harvested from "junk" I find all around my city. I believe in free, used, unwarranted, and DIY. I read Make, Nuts and Volts, and Servo at the library, and subscribe to Popular Science(I paid $11 for a 3 year subscription. Score.). I'm not that old, so excuse my stupid questions.
