Im not good with redstone circuits, so im asking here:
I saw a setup lots of pages ago, that controlled a nuclear reactor in a specific way. It turned it on when the buffer is empty and turned it off when the buffer is full. Sadly i dont understand enough abuot redstone circuits to build a somehow compact way to do this (e.g. with help from bluepower), the only way i know to do this would involve a piston. Could you show me a compact way to do this, or at least give me some words to google?
I want to set up a distillation tower for distilled water, but it should only run when the drum is almost empty, then only until its (almost) full.
