Some friends of my wife and I are getting rid of an elliptical/stairmaster combo machine. My wife wants it. She says I can have her current treadmill when we pick up the elliptical! This will give us not only a bigger motor (2 HP to the current 1.25), but I’m pretty sure that it’s got a PWM controller. We’ve been having issues coming up with the $350 for parts for the controller we’ll be building, so we’ve kind of been stuck in the doldrums for a little while. I’ll take pics/vid of the disassembly and testing of components once we get time to tear into it.
