LM317T Voltage Regulator with Pass Transistor

The pin that would normally connect to the 3.3v output of the FTDI chip on the official Arduino boards actually connects to 5v on the 5v Sparkfun board! While this is more of a Sparkfun issue, theres another side effect, if theres a voltage difference between the FTDI chip and the regulator, it's quite possible for the regulator to cause harm to the FTDI, this, in my and my dads opinion really isn't a brilliant idea In the video you can see I cut the track between the 3.3v regulator and the 3v3 pin, this allows the system to run perfectly.
