How do you make a item transporter in minecraft [closed]

It really depends which direction you wish to move your items.

Item elevators can be made with pistons and solid blocks and you can use the example below created by Etho

otherwise for horizontal movement you can use hoppers connected to eachother with a redstone input.

An old alternative(pre-Hoppers) is to use water but this is not a great choice as items will despawn if they have to travel too far or left for too long.

Though you could use a combination of hoppers and water, having the water flow into a hopper. This solution helps by not using as much iron. This would also help if you want to collect items dropped e.g. a wool or cactus farm
