I wanted to share this redstone setup for my super smelter. I know carpet duper's have been done before, but I haven't yet seen a "smart fill-up" mechanic.
In this case, I use a comparator output powered by the chest's fullness, against a 14 strength redstone input.
With some added inverters, the carpet duper is only ever powered when the fuel's storage chest is NOT full.
Now I don't have to occasionally stop by and wait until it fills up. With my current efficiency of the super smelter, it will always fill back up completely and then stop again until more carpet has been used.
I'm sure I'm not the first one to do this and just haven't seen the posts, but I thought of the "smart" functionality of it myself and was proud I could make it happen relatively easily!
