The LED method looks fairly easy, and the parts don't appear that expensive.  I know how to solder.  What I am not as familiar with is all the symbols used in circuits.  Some like the switches are not that hard to figure out.  Others are more difficult, but it basically is just a plan for the path of electrons.  I just need a reference on how to read the plan.  grin.
