You Can Get Scrooged Opening a Trap Door

Ever try opening an attic door in the ceiling at the top of the stairs with your hands full of stuff? Try spelling headache! So Larry installed a 12V motor with a cable shaft in the attic and attached the cable to the door. Limit switches stop the motor when the door is fully open and closed, and a converter ensures the correct voltage to the motor. Larry can now activate the door from the bottom of the stairs.
