Hi from the SmoothStepper Greg :-)
I'm getting pretty excited about this myself. There have been refining a few things, and it is looking pretty good at this point. I am starting to finish up the final PCB layout and I'll order a few prototypes on Monday. I need to make sure there aren't any mistakes before I have a production quantity of boards made. Unfortunately, it is going to be at about 4 to 6 weeks before I'll get them out the door. So please hang in there. Watch the Super Bowl, clean up the shop, do whatever it takes to keep your mind off the SmoothStepper :-)
Thanks,
Greg
