Cool compact power-supply. (Not TOO expensive, but a little bit of effort needed)

Recommended Posts

So one of my players got pretty depressed when his steam turbine no longer worked lol. So another player decided to look for energy solutions. He found this machine some youtuber had made, and I found it absolutely incredible. So here it is. (note, I am not gonna tell you how to craft these parts.)

This machine will fill up a resonant energy cell in a bout 30 seconds, give you infinite lava (1 bucket is needed to start it, then it produces enough energy to run it self and power the energy cell. And the bi-product of it is lava, which it produces more then is needed so you get free lava from it.)

 

 

Its a nice compact little machine and I like it.

 

Hope you do as well.

This uses a bug that can destroy chunks (an infinite energy loop bug caused by having GC wires near TE outputs).  I'd strongly advise not putting it near your base or in any chunk you want to keep (if it causes problems and there isn't a proper backup there's nothing anyone can do to help you, just a heads up in advance that people aren't being mean when they say they can't help you).

 

Here's a super simple example that'll demonstrate the bug for you if you want to see that it is in fact a bug;

That's an energy cell on top of a steam dynamo on top of an aqueous accumulator, with a wire on the side of the dynamo.

Oh so its bugged :( I didnt know. I just saw what a player on my server found on youtube. You sure this one is bugged? Made one in creativee to test it and no chunk problems atm :o

It's been explained a few times before, it's definitely bugged though (the lava fabricator doesn't make as much power as a magma dynamo can generate with it so you lose overall - use conduits instead of wire and you'll see for sure).

 

What happens is the wire passes to nearby neighbours even if they don't appear to be connected (like my example), the end result is because they do this at the start of a tick they pass to every output for every connection which is why you're getting 12x more power than you'd expect initially, then an exponential ramp up as the generators begin to store power and pass it back out as fast as they can.  The chunk corruption comes when the value of power stored in the wires gets too high to be saved by the space it has in the chunk's file, info is written outside of where it's supposed to be (there's no check because those numbers should be impossible), it saves fine but when you go to load the chunk there's garbage in an unexpected place that can cause a variety of issues.  The worse cases me and Kalbintion have linked to this have done damage to the entire world, though those were extreme and we're not sure exactly how they happened this bug is still the most likely culprit - careful with it. :)

 

The golden rule is that GC wires shouldn't touch anything more than once unless it's a GC machine and they shouldn't run alongside anything that can take or output RF (because they may connect without looking like they're connected).

 

Here's an example using the exact bug you have going on there built as efficiently as I could think of (you can probably make it 2x2 rather than 2x3 though);

Try that - the issue comes from the wire in the middle that doesn't appear to connect to the dynamo.

HISS ALUMINUM WIRES BAAAAAD

LOL :)

 

A bit of an extreme reaction, just be super careful and check everything before you leave it alone - it'll get fixed at some point anyway (it's a new bug with this version of galacticraft, the old one was that power didn't transmit at all) so it's not really a replacement for steam turbines unless you like replacing power systems every couple versions.

It's a bug that got introduced when they fixed another bug, it'll probably be fixed soon.

 

Edit: Just spotted that GC is actually opensourced, I'm out of the country for a week but I might take a look at it myself when I get back - no promises though.

 

Edit2: Just had a quick look, the section that does the advanced part of the connection checking has just been commented out, I assume temporarily (this kind of thing usually is).  It was stopping connections from happening at all, so it simply lets all connections happen now (which allows the duplicate and multiple connection bug that we're seeing in this thread).

 

In case someone wants to look at it, it's probably caused by one of the commented out sections in worldUtil.getAdjacentPowerConnections, the linking to it from BlockTransmitter (which the wires are children of) looks simple enough that I doubt it's there.

 

Here's the bit I'm talking about, git link is here.

	public static TileEntity[] getAdjacentPowerConnections(TileEntity tile)
	{
		TileEntity[] adjacentConnections = new TileEntity[6];

		//boolean isMekLoaded = NetworkConfigHandler.isMekanismLoaded();
		//boolean isTELoaded = NetworkConfigHandler.isThermalExpansionLoaded();
		//boolean isIC2Loaded = NetworkConfigHandler.isIndustrialCraft2Loaded();
		//boolean isBCLoaded = NetworkConfigHandler.isBuildcraftLoaded();

		BlockVec3 thisVec = new BlockVec3(tile);
		for (ForgeDirection direction : ForgeDirection.VALID_DIRECTIONS)
		{
			TileEntity tileEntity = thisVec.getTileEntityOnSide(tile.getWorldObj(), direction);

			if (tileEntity instanceof IConnector)
			{
				if (((IConnector) tileEntity).canConnect(direction.getOpposite(), NetworkType.POWER))
				{
					adjacentConnections[direction.ordinal()] = tileEntity;
				}
			}
			/*else if (isMekLoaded && tileEntity instanceof IStrictEnergyAcceptor)
			{
				if (((IStrictEnergyAcceptor) tileEntity).canReceiveEnergy(direction.getOpposite()))
				{
					adjacentConnections[direction.ordinal()] = tileEntity;
				}
			}
			else if (isTELoaded && tileEntity instanceof IEnergyHandler)
			{
				if (((IEnergyHandler) tileEntity).canInterface(direction.getOpposite()))
				{
					adjacentConnections[direction.ordinal()] = tileEntity;
				}
			}
			else if (isIC2Loaded && tileEntity instanceof IEnergyTile)
			{
				if (tileEntity instanceof IEnergyAcceptor)
				{
					if (((IEnergyAcceptor) tileEntity).acceptsEnergyFrom(tile, direction.getOpposite()))
					{
						adjacentConnections[direction.ordinal()] = tileEntity;
						continue;
					}
				}
			}
			else if (isBCLoaded && tileEntity instanceof IPowerReceptor)
			{
				if (((IPowerReceptor) tileEntity).getPowerReceiver(direction.getOpposite()) != null)
				{
					adjacentConnections[direction.ordinal()] = tileEntity;
				}
			}*/
		}

		return adjacentConnections;
	}
 

 

I probably won't post any more detail on this in this thread as it's not really the place (please PM if you want to talk about this), but if you want to know why the bug's happening - that's why it's happening. :)

ok kwl loader. If you do fix it oneday, do tell me :D perhaps u cud fix a glitch with GC as well. People who use it in creative world, can fly into space, then float down, but end up in the over world, which is survival world, so they have creative in survival. Is there a way to make gc not tp players to overworld when they fall out but bk into the world they launched from?

This power multiplication bug between aluminium wire and TE is fixed in Galacticraft builds 1024 and later.

We maintain a beautiful changelog at http://ci.micdoodle8.com/job/Galacticraft/changes

so that players like you can see what is being fixed.

If you want to have all the most recent updates in Attack of the B Team then ask the modpack makers to update to the latest Galacticraft version which is 2.0.13.

NOTE: generally speaking, whatever build is in the modpack, server owners can safely update server-side only to the latest build as long as it has the same Galacticraft minor version number. Example: if the modpack has 2.0.12.1026, the server can actually run 2.0.12.1059 to get the latest bugfixes. Any Galacticraft 2.0.12 client should have no problem connecting to a server running 2.0.12.1059 and the players will not even know the build number is different. Hope you server owner guys understood this.

And @Loader? Lol at trying to fix it in the source code yourself instead of looking at the changelog, coming to the Galacticraft forum to ask, or maybe opening an issue about this on Github.

cheers all

kwl man, gud to know. Hopefully the modpack makers can update the galacticraft, but i dunno if they can since bteam is for 1.6.4 and latest updates might b for dif versions :/

Modpack was updated to use 2.0.12.1026 in the latest version (not recommended, so 1.0.11+) so this particular issue is resolved in the latest version of the modpack according to his post but isnt the latest version of the mod (2.0.13 is latest for the mod on 1.6.4) - so there is still an update that can be done.

      I've made a nuclear reactor in multiplayer. The reactor is from big reactors, so it outputs RF. As visible on the image, I made a conversion setup but it is not working. The MFE is not getting charged at all, even though everything on the energy bridge looks fine and it's fully charged. What am I not seeing?

      Hello all,
      I've managed to create a very compact blaze rod emc generator for Tekkit Legends that fits within a 3x4x4 space, in a couple hours it can generate enough emc to make a full set of gem armor, and now I have several stacks of red matter furnaces laying around. It also doesn't have any laggy components and can easily keep up with the EMC needs of everyone on my server. This design might work on other versions of Tekkit, if someone wants to test it out then let me know.
      Project 71 EMC Generator
       
      This is a basic tutorial of how to build it, however this is an END GAME emc factory and has some fairly expensive pieces. If you are looking for something a lot cheaper (and slower) then check out this economy version. Also, if you are unfamiliar with some of the items in the resources list then don't be afraid, this guide should cover how to set them up and break it down into bite sized steps.
      The resources you will need are:
      8 high voltage solar panel or a an equivalent EU power source 7 MFSU or an equivalent EU storage system 2 energy condenser MK2 4 item teleport pipes 2 power teleport pipes or an equivalent RF power source. You will also need an RF power teleport system in order for these pipes to receive power. To learn how to do this, click here. You don't need a whole lot of RF, but being able to teleport it is very useful. 3 cobblestone kinesis pipe 4 flux pipe 1 macerator 8 glass fibre cable 2 iron transport pipe 2 clay transport pipe 6 wooden transport pipe 16 overclocker upgrade 2 transformer upgrade 1 energy storage upgrade 1 blaze rod (at least) The resources above can be made from the following raw materials:
      32 red matter 32 dark matter 155 diamond (2 stacks +27) 41812 refined iron ingot (653 stacks +20) 71 iron ingot (1 stack +7) 142 gold ingot (2 stacks +14) 29158 copper ingot (455 stacks+38) 16601 tin ingot (259 stacks +25) 8 clay 21 bronze ingot  2 sugar 113 coal (1 stack +49) 1 charcoal 12288 coal dust (192 stacks) 25482 redstone dust (398 stacks +10) 14 glowstone dust 266 lapis lazuli (4 stacks +10) 55314 rubber (864 stacks +18) 8 obsidian 3 flint 2103 wood planks (32 stacks +55) 12328 glass (192 stacks +40) 32844 cobblestone (513 stacks +12) 1 blaze rod The total emc cost is 44167992, but the vast majority of this cost comes from the cost of the high voltage solar panels. These also take a long time to craft on top of how expensive they are, which is why I would recommend this guide if you have not already crafted them.
      This device will still work even if you don't have all of these HV solar panels and MFSUs, but it will not work nearly as fast (and make that horrible noise that macerators make when they don't receive enough power).
      This design uses flux pipe to transfer RF power, and that requires making sweet redstone ingots. These are very cheap and extremely useful, but they are a headache to make, which is why I would recommend learning how to from here.
      When choosing an area to build this thing, remember that like most other machines it has to be in a loaded chunk in order to run while you aren't near it. The source it is getting RF power from must also be in a loaded chunk. You can either build them in a spawn chunk, or you can use a world anchor to keep them loaded. You can also use a teleport tether, but world anchors seem to be less buggy and after a very very long time will run out of juice, meaning that if someone drops down a world anchor somewhere on the server and forgets about it then it wont be using up processing power forever. I would also recommend embedding the whole thing in the ground so that it isn't sticking out like a sore thumb.
      Embedded EMC Generator

      IMPORTANT: DO NOT BREAK ANY MFSUs OR SOLAR PANELS WITH A PICKAXE!! If you are planning on building this thing then you know how expensive they are, and they will turn into useless machine blocks unless you break them with a wrench.
      Now that you have a (very long) shopping list, we can get started on how to put this monster together. For the sake of simplicity, I've broken it down into layers.
      First Layer (bottom)
       
      It is a pretty simple layer, but you have to be careful about which direction the iron pipes are flowing. Right click the lower iron pipe with a wrench until the clear end is facing toward the clay pipe on the bottom. For the iron pipe on top (circled in red), it is going to be a little bit more stubborn. I'm not sure if it is a glitch or intentional, but iron pipes have issues connecting to wooden pipes. To force it to do what you want, you will have to temporarily replace the wooden pipe in the black circle with a different type of pipe, then use the wrench to direct the iron pipe in the correct direction. Once the iron pipe is correct, then you can add the wooden pipe back in. Watch this GIF to see exactly how to do it. Next add a blaze rod as the target for your energy condenser MK2. if you are wondering if you can get away with a normal condenser instead of a MK2 condenser, then sadly the answer is no. This emc generator has a very high output and a regular condenser can't keep up, so your pipes will get overloaded and likely explode unless you use a MK2 condenser.
      GUI for Energy Condenser MK2 with Target Set to Blaze Rods

      IMPORTANT: DO NOT ADD IN THE GLASS FIBRE CABLE YET! Before inserting the cable, you must first place down your macerator and add in 2 transformer upgrades. If you connect the macerator to a HV solar panel before doing so, it will explode! Also, while you are at it, add in 16 overclocker upgrades and 1 energy storage upgrade. If your macerator GUI does not look like the one in the picture, you probably have a rotary macerator instead of a regular one.
                                                                  Second Layer
             
      Power Teleport Pipe GUI

      Once you add in the upgrades, you may now connect the solar panel to the macerator using glass fibre cable like in the photo. In order for your power teleport pipes to work, they must both be set to the frequency of your power teleport system, and be in "receive only" mode like in the picture. Alternatively if you didn't make a power teleport system, then you will need to remove the power teleport pipes and kinesis pipes then connect combustion engines up to all of your wooden transport pipes. However, combustion engines will need to be restocked with fuel and run the risk of exploding so I would highly recommend you make a power teleport system (link is in the list at the beginning).
      The wooden transport pipe (circled in black) needs to have the solid side facing the macerator, if the solid side is facing the condenser instead, then give it a whack with your wrench to fix it. Also, another wooden transport pipe underneath the macerator will need to be fixed as well, this one also needs to have the solid side facing the macerator. Watch this GIF to see what I'm talking about.
      Third Layer
       
      Use your handy-dandy wrench to make sure the iron pipe is facing the clay pipe. Also use the wrench to make sure that all three of the MFSUs are facing the glass fibre cable. This GIF should sum it up.
      Fourth Layer (top)

      Once you have the last of your high voltage solar panels and your MFSUs in place, then just use the wrench again to make the MFSUs face your glass fibre cables. The MFSU circled in black is easy to adjust, but the three MFSUs in the red circles are a bit trickier. You must go up underneath the device and use a wrench on the bottom of those three MFSUs to make them face the fibre cable, as shown in this GIF.
      Just a few final steps before it is up and running. Remember the item teleport pipes from Layer 1 and Layer 3? They need their frequencies set up as well.
      Setting up the Item Teleport Pipes
          
      The item teleport pipe in the black circle and the item teleport pipe in the red circle must have the same frequency. If you already have teleport pipes in your world then be sure not to choose a frequency that is already being used. For the sake of this example, lets set the frequency of these two pipes as 1. Make sure the item teleport pipe in the black circle is in "send only" mode and that the item teleport pipe in the red circle is in "receive" only mode. The item teleport pipe in the yellow circle should be at a different frequency than the other two, for this example set it to a frequency of 2. Once you've chosen a frequency put it in "send only" mode.
      Item Teleport Pipe GUIs: Setting Frequencies and Modes

      Now there should only be two blocks left unplaced: an energy condenser MK2 and one last item teleport pipe. Choose a convenient location in your world (probably next to a transmutation table) where you would like to receive emc and place down your condenser MK2. Next put the last item teleport pipe under your condenser MK2 and set it to the same frequency as the item teleport pipe in the yellow circle. Also set the item teleport pipe in the blue circle to "receive only" mode. The condenser hooked up to the item teleport pipe in the blue circle has to be an MK2 condenser otherwise it will overflow and throw blaze rods all over your nice home. You should set the target of the condenser MK2 to be a stackable item with very high emc value. I use red matter furnaces, but if you can not afford to make one, then use something like dark matter or red matter. After the emc generator has been running for a couple minutes you will have enough emc for a red matter furnace so don't worry too much about it.
      After you have chosen a target for the condenser then return to the emc factory and double check that all of your iron and wooden transport pipes are facing the correct directions. Also makes sure that your flux pipes are powered (they should show that they have ~8000/8000 RF). Also make sure that all your MFSUs are facing into the glass fibre cables. Now throw a few blaze rods into the macerator. If it starts churning out blaze powder and manufacturing blaze rods then you've created a functioning emc mega-generator! If you are wondering if it is working correctly, then this should give you an idea of how fast it should look at full efficiency: Flow Inside Pipes, Macerator Speed.
      Unless you are making gem armor and throwing it in lava then your new Project 71 emc generator should produce more emc than you could use!
      Finished Project 71 EMC Generator

      TROUBLESHOOTING:
      If after a few minutes then your machine starts spitting blaze rods/power everywhere then either your transport pipes aren't hooked up correctly or your item teleport pipes aren't at the right frequencies.  if your machine doesn't start up at all then you may not have the right upgrades in the macerator, or your flux pipes aren't receiving RF power. Another potential issue is that your macerator might have blaze powder stuck in its input slot instead of blaze rods. You can check if your pipes are receiving power by hovering over them. You can tell if your power teleport pipes are sending power if there is a blue stream of energy flowing through the cobblestone kinesis pipes.  If your cobblestone kinesis pipes DO NOT have a stream of blue energy flowing through them then there is something wrong with your RF power supply. This is probably because the RF generator is in an unloaded chuck or your world anchor has run out of ender pearls. If neither of these things is the problem, then try breaking your energy bridge and putting it back down. (this is a bug that sometimes occurs when teleporting power across a server) If your machine is running slowly, then it is not receiving enough EU to power it at full efficiency (remember, this thing chews through 7-8 HV solar panels worth of EU). If you have all 8 solar panels connected up to it, then I would double check that your MFSUs are facing the correct directions and that there are no "solid" blocks directly above the solar panels. After a minute or two then all of your wooden transport pipes should be flowing with either blaze powder or blaze rods. If not then either your flux pipes are not receiving power or your wooden pipes are facing the wrong way. If you see blaze powder and blaze rods flowing through the same pipe, this is normal. So long as the macerator always has a supply of blaze rods to grind then it is not losing any efficiency. If it grinded up the blaze rods you put in initially, but then the macerator ran out of blaze rods then it probably wasn't a big enough stack to get it started. Restock the macerator with a larger stack of blaze rods. If there is a large number of blaze rods bouncing back and forth inside the pipe (and not entering the condenser, then you might have mistaken a clay pipe for an iron pipe. Also, an iron pipe may be facing the wrong direction. To fix this, turn off the emc machine and break the pipe to let the items drain out, then replace it facing the correct direction and restart the emc machine.

      Ive build some Magnetic dynamos and lavafabricators for infinte Lava = infite energy, but they need too much lava , so build more lava fabricators, but it didnt work.
      Is there another way to create  a alot of lava? (PICTURE: https://www.pic-upload.de/view-32722914/Dynamo.png.html
