 My name is Michael, and I'm located smack in the middle of Phoenix, Arizona. A year or so ago I had a little Nintendo DS Lite repair service going for systems with fuses gone bad, and that's what really turned me on to electronics and their innards (I'd always been a curious little monkey, taking stuff apart and looking at components even though I had no idea what the hell I was looking at). I registered here for learning purposes, but I'll do my fair share of goofing off, too.

 Well, I'l follow the leader lol. I'm a student of the master. I had some computer experience back in '86. It was all DOS. Not to long ago, I thought it was something just to do minor things like reformat and replacing drives. I'm learning hardware mainly. Though I am dabbling in site building.
 Personal about me, I'm a nurse. Doing some serious research on becoming a PRN/midwife. Yes some would say it's foolish to go back to school now, but with "someones" support I will be in the top of my class. I hope to minor in some type of technology. I love to read, ride mtn bikes and want to learn to fly.
 My age, thirty-something, this monday I might add. ​ ​Comment
