Yeah, I hate that this stuff gives me the trouble it does I'm a reasonably intelligent person, but electricity... sometimes I feel like I'm stuck in an Insane Clown Posse video (Fuckin JFETs, how do they work?)
Even so, I've found myself modding a layout to do something a bit different, or adding a switch, in this case, and I think "Hell, a little while back I'd be looking at that cross-eyed." So when I try to talk to someone about this or that circuit and they look at me like a talking shoe, I realize I've learned quite a bit. :)
