Bucket Filler

This is a one block mod. The bucket filler, will face like observers when you put them down on the world. It will observe any cauldron in front of itself. When the cauldron is full with water/lava or powdered snow, it will fill any empty bucket sitting inside it's inventory.

The inventor is a sided one. The input accepts items from top and the output sends items to down direction. you can use hoppers and chests, or any mod tube to insert and extract from inventory.

The block sends redstone signal when there is an empty cauldron in front of it. any water or snow powder cauldron that is not full, will send the redstone signal too. The only time that the signal is off, will be when then cauldron is full. This way, you should have the ability to easily hook this machine into your lava production system for pushing the blocks around with awareness about the cauldron situation in front of the machine.

The redstone behaviour is now changed in version 2. Now you will get one tick pulse when the block is emtying a full cauldron in front of it. If there is no empty buckets to finish the job or if the cauldron is not full, or if the output slot is full and block can't operate because of it, there will be no redstone signal.
