That projector definitely uses dc motor,so there must be speed regulation circuitry somewhere inside.
On that speed regulation board there must be 2 potentiometers for fine tuning the 18/24 fps speed. You'll need insulated screwdriver to adjust that.

All in all,that means you should really don't need to add anything to make it "adjustable". [Wink]

Thank you very much Nantawat. I founded the two little pots and it and it worked very good. Thank you again.
