Here comes a real masterpiece! The Geneva Drive GBC module from Takanori Hashimoto is a fantastic Great Ball Contraption. The big six-arms wheel sitting at the middle of the building is moved thanks to a tinier yellow wheel located underneath. The continuous rotational movement of the yellow wheel is transformed into a jerky rotation for the big wheel. Your favourite basket and soccer GBC balls, after a nice ride on a Ferris wheel, are going through a rotating journey inside one of the colourful buckets present at the end of each arm. Another smart mechanism, dancing in perfect sync with the yellow wheel, is expulsing the balls to the destination ramp. This GBC module is definitely a must-build in your collection.
