    Thanks for taking the time to post such a great tutorial. I apologize if this is taken into account in some of your later tutorials (I intend to read them all!), but I just have one question: Some components, like the little LCD screens sold here, require 3.3V. How would this usually be provided? Would it be a parallel split at the end of the power circuit and another voltage regulator, or would it be a split before the voltage regulator and then have two circuits, one at 5V and one at 3.3V? I’m just trying to understand how to take advantage of having 9V (albeit unregulated) and needing both 5V and 3.3V. :) Thanks again!

No public wish lists :(
