Just for clarification on 1) Wire a 100R resistor in series after D1. Everyone has probably wired two resistors in series, you use the same technique (and some heat shrink) and wire the final result where D1 goes.
is that wire the resistor in series with the 1n5817(d1)? and could i use a 1n4001 instead of the 1n5817?
