Great work Sgt.,
Might work for me since I am electronics illiterate and don't know my way around a circuit. Since you are making a tutorial for those of us that are electrically challenged, I would recommend that you let others know that capacitors hold electrical charges and they maybe shocked if handled improperly. I know that you'd need a large capacitor from a computer or television to due serious harm. Just my 2 cents.
Here's a Wikipedia on a Diode Bridge for those who'd like to know more about the circuit:

Keep up the good work,
