John,
It sounds like you are having fun with your solar electronics.
Mark,
It helps that my boss at my second job is letting me work the morning shifts only. It is harder working the evening shifts and then having to adjust to working the 3rd shift on the weekends. I have been learning a lot at my internship. I am applying what I have learned to my senior design project. I have been having trouble communicating with an IC chip and I finally had an a haw moment and got half of it to work.
It sounds like you have a pretty cool LED setup for the fish tank.
Nick
