Until minecraft 1.5 there were few ways to transport goods such as food, cobble, or ores. Since the Hoppers and Droppers come out in 1.5 there has been makeshift pipes. But this one is the best of all of them:
The Ingredients:
Redstone repeaters
Droppers
Blocks
Levers
Redstone
Start by digging out every other block making a line.
Fill your holes with repeaters.
Place blocks on the surface next to the holes.
Put repeaters in the spaces in between.
Drop you droppers over your holes making a straight line. And make sure they all point the same direction.
Connect repeaters to the blocks that start the machine ( the back ).
Add a lever.
Now to start the machine fill the first dropper with items and flick the switch on and off. You could also add a clock if you want ( but that makes annoying clicking noises so...).
Thanks for reading and enjoy!!!
