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.
Elthy, in short, you want to look into RS Latches.
A RS Latch is a Reset-Set Latch. When one side receives a pulse, it changes to one state. When the other side receives a pulse, it changes to another state. This is the only complicated circuit you should actually read up on. ProjectRed has documentation on it I believe if you can't find a BP equivalent.
Note that I'm talking about "pulses" rather than "signals". The difference is that when your buffers send out signals, you may need to transform those into pulses (rather than a constant signal) to make the RS Latch work. So, also look into Pulse Formers (iirc).
A great way to work on setting this up is to lay out your circuitry in a big room with lots of area to work with. Use a pair of buttons that will act as your incoming signals representing "Buffer now pretty low" and "Buffer now pretty full".
Basically what you want to have happen is: every time the left side of your RS latch receives a pulse from the "Help, buffer is low", you want the RS latch to emit a signal to your generators to start up. Conversely when the other side of your RS latch receives a "help the buffer is full" pulse you want your RS Latch to STOP emitting that signal so that your buffer has some time to empty.
The same logic here applies to liquids and such for your distillation tower setup.
