Work in progress embroidery machine. Two linear actuators were attached to a domestic sewing machine, which has been modified with a custom speed controller and rotor position sensor. The machine is controlled by a separate box which contains the stepper motor drivers and two micro computers. Yes the control panel does have an old teliphone dial on it to select the pattern. At the moment the machine can only sew stitch locations specified by a long list of coordinates. Software is being developed to assist in making patterns for the machine.
