I’m new here so I've been searching thru the archives just to get the "feel" what is going on here. It's interesting to read about the different project you all come up with. So... why do you do it? Are you an electrical engineer and do this sort of thing for a living...or are you just someone that enjoys making things for yourself because you can't buy the "exact" thing you need? I'm sure there are many other reasons why you enjoy this either as a profession or a hobby. Care to comment? Maybe you could include what your main area if interest is too.
