Redstone facade

The Redstone facade is a facade added by JABBA to use on Better Barrel. This item will need a Redstone upgrade to be applied on the barrel first. A barrel with this facade will output a redstone signal of strength 15 when the barrel is full by default. A Barrel Hammer can be used to change any redstone facade so that they either output redstone signal with strength 15 when full, when empty, or output redstone strength similar to a comparator: 0 when empty, 15 when full, and 14 evenly spaced grades from 1 item through to one less than capacity.
