Regulator Temperature Fix

The regulator can be de-soldered, rotated 180 degrees, and attached to the back side of the board.  This should provide clearance for a heatsink.  The heatsink provided in the kit for the final works very well for this if you are not using it.

Another option, if you are using a metal enclosure, is to remove the regulator and attach it with 3 leads to the Raduino board. The regulator can then be screwed down to the chassis which should have no issues dissipating the heat.
