IAC controller circuit

[rauscher at icst.com]

OK, finally got it together. I finished the schematics and
the write-up on the stepper motor control circuit. It's all
been uploaded to the 'incoming' site.

Files:

Stepdrv.txt         The what/how/why and where.
StepDrv1.gif        Image, page 1 of schematics
StepDrv2.gif        Image, page 2 of schematics


Now, before anybody jumps up and down about the hand
drawn schematics, well, I'm a software guy. I almost
had to use a crayon ;) {the sharpest nearby items are
the corners on my keyboard}.

The purpose of this circuit/project is to be able to
control the IAC by itself. That is, you can extend or
retract the pintle at will. This is a stand-alone
controller.

Have fun, any questions, I'll be here for awhile. (At
least 'til next vacation/holiday).
