    What is the question?

    Personally I thing using pin 3 for driving the MOSFET is the better option.

    A question would be useful.

    I recently built one of these that used pin 3 to drive a MOSFET and it worked perfectly. I am still inexperienced but this circuit looks like it is designed to drive an NPN.
