Cobblestone Generator

A cobblestone generator which makes and renews a platform of cobblestone, while it gets blown up into the water stream collection system bellow

cobble gen with a piston on observer clock pushes out a line of cobblestone-when the line reaches 11 blocks it is pushed and a new line is formed-once a platform is made 3 dispensers with TNT on a hopper clock blow it up- the items fall into a square of flowing water and then flow into a hopper.

If the block 11 platform is full- an observer clock activates all the pistons to fill the rest of the platform
