DIY Low cost Servo Motor

Presently i am working on converting ordinary DC brushed motor to closed loop servo. I scavenged a DC motor from embroidery machine and 3d printed a low resolution encoder wheel (4-slots 16PPR quadrature mode).. Grabbed two optocoupler as a encoder sensors and purchased IBT-2 43Amp dc motor driver f...
