i have a broken 8' projector screen that doesn't roll up any more and i thought
it would be fun to make it into an electric one.
what kind of motor / controler setup do i need so you press one button and the
motor rolls out the screen the predetermined length for 8' and then stopps...
then you press the button again and the motor does the reverse?
how do you set the start and end points for an electric motor like this?
obviously i am a complete fool with this due to lack of experience, but i am a
pro tinkerer determined to save this screen.
