This is an ongoing project I've started about 4 or 5 months ago. In an elusive search to find a decent stepper motor driver circuit without breaking the bank, I've narrowed it down to this, A3799_Stepper_Driver [schematic, PDF]. Board diagrams and artwork to follow shortly.

Update 23SEPT11:  While the circuit is still viable, I am abandoning this project.  I ordered a couple of the A3799's from Digikey earlier in the month and they have arrived.  TSSOP chips... too damn small to work with, and too fragile to do anything with a CNC machine.  I'll finish off what I have, bundle it up and post it shortly. (I have a lot on my plate at the moment).
