Available in Buildcraft version 3.1.5 only
Stripe pipes can place blocks or edit blocks by using a hoe. When powered by an engine, it will pick up the object in its front. The stripes pipe has currently been removed from upcoming version 3.2.0 for Minecraft 1.3.2.
Stripe pipes can be used (though rather inefficently) to create fully automated wheat farms. When a hoe passes through the pipe, it will till the grass or dirt block directly in front of it, leaving the hoe on the ground. After that you can send seeds then bonemeal through the pipe and the seeds will be planted, again in the one block directly in front of the pipe, then fertilised and fully grown. Powering the pipe with an engine once the wheat has grown allows it to harvest the wheat.
Note, while it is possible to till and plant a block that is on the same level as the pipe (see lefthand panel in image to right), it cannot have bonemeal applied, nor the wheat autoharvested. For best results the dirt block should be one level lower (righthand panel, right), with the wheat growing on the same level as the stripe pipe.
Autobuilding transport pipesEdit
The stripe pipe can also be used to autobuild a transport pipe. Simply place it on the end of a short length of transport pipe, then send more transport pipe down the pipe. The stripes pipe will replace itself with the new section of pipe and move one square forward.
Note: This only works with transport pipes. Attempting to send waterproof or conductive pipes into the stripes pipe will crash minecraft.
