Windmill Lift is a cool little GBC module from Sam Friesen. This LEGO Great Ball Contraption is composed of an input bin with a mechanism that is pumping GBC balls by the bottom and carrying them to a little 3-blades propeller. The mechanism is quite smart and reliable even when a lot of balls are present within the entry bin, which is quite remarkable in design for such a compact LEGO GBC. You can reproduce this awesome pocket LEGO ball machine, perfect for beginners or to build with your kids, thanks to free building instructions provided by Sam Friesen.
