Motorised Zoom/Focus Assembly from A130-type PJs

Sure many members here have extracted M140 diodes from used A130 PJ series.

Has anyone tried to hack the motorised Optics unit? I wonder how the motor(s) moving lenses can be driven from an external power source.

Previously I have tried to apply voltage on any pair of 4 coloured wires but it was not moving - so it was for sure a stepper motor.

What kind of stepper motor driver could I try? I have been told that thre are some Arduino based etc. but I want a small one and not with hundreds of not needed options...
