Clarification on some features that may be confusing: brimstone soaks up lava, and elevator blocks work by there being another elevator block 3 blocks either above or below it. It is challenging to list all the crafting here so you may have to use JEI if you are playing survival. The checker can be used to detect if the block in front of it equals the block in it's inventory when updated.
