Sugar cane farm

by pawfix

An automatic sugar cane farm based on my previous bamboo farm. How it works? Flying machines destroy sugar cane, which then is picked up by minecarts with hoppers which then put it back into actual hoppers. How to power it? behind the flying machines there is line of redstone. U need to place the redstone so its connected and then place a block next to obsidian block, so the observer will send the redstone signal and power it. WARNING! You cant destroy the block you placed instantly, but right after the machine fly off.
