Unregulated DC Power Supply

The stepper motors require a lot of current.  I threw together a quick-and-dirty high-current unregulated DC power supply to keep the steppers fed.  I also use it to power the HobbyCNC board.  I put the supply together as a prototype, and it worked, so I just ‘shoved it in the drawer’ and left it alone.  This is obvious in the photos.
