|Details: You can use this ball clock to tell time. The third row tells the hours, the second row gives 5 minutes increments and the remainder is shown by the first row of balls. Mechanical logic keeps the balls flowing into the right places. In a technique I'm surprised I haven't seen in a Great Ball Contraption module yet, a ball lift is made out of chain with a few pieces of tread in the middle. Half-width beams are then able to attach to the treads.|
Building instructions for this model are also included in the Brickshelf gallery.
