Homebrew PCBs

I've done what I believe are improvements to the 12V stepper motor driver
schematic I had in the Photo section.  It's no longer there, I moved it to
the CNC folder of the Files section.

I've added opto-couplers between the CMOS chips and the transistors, lowered
the CMOS voltage down to 5 volts and increased the motor voltage to 24 volts
(which is what my motors are rated).

Comments please on the modifications.
