Ok I promised to go over the ComputerCraft code I found and am using to control my Big Reactor, so here goes:
The code is written by Lolmer/Eric Sandall and you can find it along with descriptions and more here:
https://github.com/sandalle/minecraft_bigreactor_control
What it does is to monitor any reactor(s) and turbines connected to the computer and adjust them according to set parameters. For example for reactors the parameter is to try and keep the temperature between 850C and 950C(highest power while staying below 1000C and therefore highest possible fuel efficiency), and the program will then automatically adjust the control rods to match that interval. The program will also disable the reactor if the internal power buffer exceeds 85% and turn it back on once it drops lower than 15%, effectively managing the reactor completely on its own. While doing all this it gives you a neat overview of the reactors stats on a connected monitor, which also serves as input for several functions of the program(manual override, manual adjustment of fuel rods).
If you are completely comfortable with ComputerCraft and Big Reactors then you can at this point just go get the code from the site linked above. There should be plenty documentation there and in the header of the code to get you started. BEAR IN MIND! that the code in the link above is written for ComputerCraft 1.6+ and will not work on lower versions. If you are using a lower version of ComputerCraft(Like in Monster 1.1.1 and lower) all occurrences of "term.native()" needs to be changed into "term.restore()". Now I have done that for the following two links and hope I don't get into any trouble for sharing them(I take no credit for anything in this code, only done a search and replace of the above mentioned terms):
Lolmer's EZ-NUKE, modified to CC<1.6
Lolmer's EZ-NUKE startup code, modified to CC<1.6
Now for the rest of this guide I am going to assume that you have watched some basic Big Reactor guides but otherwise don't necessarily know anything about ComputerCraft etc.
The code is capable of handling several reactors and turbines at once, but for this demonstration I am just going to focus on one reactor. Setting it up with more should not be any different except you will need another monitor for each connected device plus one monitor for main overview for anything above one reactor. More detailed description on how this is done can be found in the readme on Lolmers site and in the header of the code.
The first thing you are going to need is a Big Reactor reactor of any size and shape.
The only thing special you are going to keep in mind when building it is to include a Reactor Computer Port in the frame. Here it is the second "special" block from the right.
Next you are going to need an Advanced Computer and 6 Advanced Monitors from ComputerCraft. Place these down anywhere you want, they do not need to be touching each other or the reactor.
Now the Monitor needs to be in the shape shown above: 2 high and 3 wide. You can place lots of monitors next to each other to make a much bigger monitor, but fonts etc. does not scale if you do and you would end up with using the same area of the monitor, just up in the left corner.
Next you will need to craft 3 Wired Modems and some Networking Cable also from ComputerCraft. You place one Modem on the Monitor, one Modem on the Computer and the last Modem on the Reactor Computer Port. You then connect the modems up with the Networking cable.
Now very important is that you rightclick each modem once. Doing so they should change colour(with Soartex they get a red ring) and you will see a message in the chat window. Once this is done the modems are activated and ready to communicate.
Now all the "physical" parts are in place and all we need is to get the program loaded up. Luckely this is very simple, but you do need to figure out which version of ComputerCraft you are running so you can choose the right program. If you are using a FTB pack, go
Here and find the version of the modpack you are using and see which CC version it has. Else look in your launcher/ingame "Mods" menu etc.
Now that you know which version of ComputerCraft you are using go to your Advanced Computer, rightclick it to open it up. It should look like this:
(actually that version number up top might tell you which version of CC you have
Not sure).
Now all you have to do is type in the following(or copy+paste):
CC 1.6+: pastebin get ZTMzRLez startup
CC<1.6: pastebin get jXgkfhfW startup
Hit Enter and the computer will automatically download the program and store it under the name "startup"(the program named startup automatically be run when the computer gets loaded and thereby starting the program again after restarts etc.).
Once it is done downloading type in "startup" and hit Enter and the program will run for its first time.
And BEHOLD! the reactor starts up, the monitor lights up with information and the program starts to dial in the fuel rods to match the temperature interval.
(Connected up some storage and let it run a bit for this image. Here it is balanced out at a temperature of 927C).
Now some bonus information. The monitor is actually a Touch screen and you can use it as such. Walk up to it and rightclick on the "Enabled" bit for example to turn off the auto-adjust. Then click the "<" or ">" to manually adjust the fuel rods to your liking. Or turn the reactor off by clicking on the "Online" part.
