    In case someone reads this.

     

    I just learned about gear motors. they are basically DC motors with gears build in to produce more torque thus being able to spin at a lower RPM.

    I have seen them go as low as 2 RPM.

    Thank you very much Ajish Alfred!

     

    I also looked into DC motors but a friend of mine said it would get to hot if it were to spin at such a slow speed, is he wrong in saying that?

     

    A 9v battery seems kind of big, would a one sided PCB still need that amount and are there rechargable 9V batteries? (never heard of any)
