Today’s post is an introduction to the Great Ball Contraption, or GBC, with a tutorial made by Mano’s LC. The GBC is a series of interconnected modules that move small LEGO balls through and are a combination of excellent engineering and unique creativity. Mano’s fantastic tutorial serves as an introduction to GBC with one of the most essential modules. Known as a stepper, these allow balls to move from a lower module to a higher one, and serve to be a simple bridge between modules while giving the balls the height and therefore momentum for future modules.
