Lego GBC Castle Module

This lego great ball contraption (GBC) module features a shooter mechanism to lift the balls up. The range of the shooter mechanism can be easily adjusted with a gear at the back, it uses a large linear actuator attached to a shock absorber to do so. Part of the back of the castle is made from lego technic 6L half beams to slow the balls down. I built this module because I wanted it to be easier for people to get into building GBC modules, as it can be quite hard to build your first one by yourself. You can watch it running here:
