This is a Cobblestone Generator that uses pistons to stack cobblestone into 3 rows.
Available control is on and off button ofcourse to stop the clock circuit.

I have seen alot of cobblestone Generators out there but none wich got a good touch to them. So i made it look somewhat nicer.

The schematic was saved using Version 0.1.0-10 I am not sure if it is the latest one, but on the forum it said it was the last one he was going to work on.

And as always sorry for my bad grammar.

Additional Notes

Recommended to turn off the generator when out of use.
No need for credit ;]
