What you can do with LEAP Motion and a Coil Winder stepper motor, shows CNC Design Limited in a video.
CNC Design Limited: We had a Leap Controller arrive a couple of months ago now, but had no time to play with it, till today!.
So we grabbed the nearest stepper motor that happened to be on our CNC Coil Winder and after playing around in VB.Net we got it moving !
All a bit of fun and now thinking of what practical application we could use it for ummmm !
