HUGE cobblestone generator/storage

to my knoledge this is the biggest cobblestone maker out there and uses a reapeater circuit (NOT MY DESIGN) and makes cobblestone slowly. the capacity is 1320 blocks and is intended to be turned on and left on for a while when your doing someting else.

UPDATE: this is my first project and for the first few to download i noticed i cut out a section of the piston control making it so its impossible to fill it up with cobblestone and i am very sorry and posted this update

*if you log out while the generator is still on you may need to mess with the piston timing circuit when you log back on*
