Guy builds a 20,000 Leagues Under the Sea “Nautilus”, complete with mechanical iris door

Made by Alan Rorie: “The motorization of the large aperture was surprisingly easy. I used two small DC motors with spur gears and nice torque mounted on either side of the cam ring. I then welded chain around the cam ring turning it into a giant gear. It worked the first time I tried it. I controlled the two motors with an Arduino and a motor shield, two limit switches and a few lines of code. I then modified an old positioner and inserted a set of buttons, so that when you pull the handle of the positioner it trips the buttons and turns the motors.”
