Question for Readers

We're fast approaching the end of what I would call the 'basic tutorials', and the point where I'll move on to interfacing with the real world and other cool toys and devices. Unfortunately, that means I need some cool toys and devices. In brainstorming ways to help fund this little hobby, a friend suggested to me that I might consider using Google AdSense on this blog. If I were to do so, I would want it to be unobtrusive, as my intent is not to sell things for other people. How would you feel if I were to do this? Would I be better off thinking of another way to raise a little hobby revenue?
