The latest LEGO GBC creation from Phi.L will amaze you. Archi is a Great Ball Contraption module consisting mainly of a huge toothed wheel. The GBC balls are hoisted onto the side of the wheel of this LEGO ball machine and rotate around the big wheel to land on the exit ramp of the module. The ingenuity of this module lies in the mechanism that makes the central wheel turn: two articulated arms push the wheel alternately thanks to the notches placed on the side. You really have the impression of seeing a human automaton progressively pushing the big wheel of this GBC module. If you are enchanted by the magic of this LEGO ball machine, you can reproduce it for free thanks to the building instructions made by Phi.L and available on the Planet GBC website. So cool!
