Kak111... thanks!!!
I think i understand everything except the cap values.
You have 470uF... 2200uF for C1 and 470nF... 2200uF for C2. I don't understand... why there are 2 values for each?
Thanks again,

Another quick question: Since i am already regulating the voltage to 5v using the 7805, is the 7812 really necessary? It seems like with this circuit i would be regulating to 12v with the 7812, then sending that 12v to be regulated to 5v with the 7805. Is that important, or can i just use the 7805 (rated up to 35v 1a) to regulate from 17v down to 5v?
Thanks!
