Talk:Redstone circuits

Elaboration on several topics
Could the creators of these sections please edit to include more information on the workings of their devices: For the 5/1 Clock, it's just worded very strangely, and since there's no schematic, I can't build it to see what's going on. For the 4 Clock, elaboration on the workings of this clock, as well as a version of the schematic from the forums that fits the schematic style here would also be appreciated.
 * JK Flip-Flop
 * T Flip-Flop
 * 5/1 Clock
 * 4 Clock
 * Also, are there any more legitimate notes we need to add to the Important Notes section? Otherwise, I think the "needs expansion" note can go.
 * --Allus 10:52, 28 July 2010 (UTC)
 * I added some description to the JK and T Flip-Flops. I'll try build the wierd 5/1 clock.. Should I add the inverse Q to the Flip-Flops? (Is there even an easy way to do that without it getting bigger?) --Samonite 15:08, 28 July 2010 (UTC)
 * I just tried the 5/1 Clock. If you connect the output to anything other than a door it wont work. This means that you can't connect it to any gates or just even Redstone torches. I have removed 5/1's from the article. --Samonite 15:45, 28 July 2010 (UTC)
 * The 5/1 takes some tweaking to work, I just added it back not knowing where to check to discuss first I will test it again, until then ill remove it. --wolf_alex
 * Looks like its not working how I want right now, but it works the same way when not attatched to doors, as I said it needs tweeking to work --wolf_alex
 * I got it working, you have to build the 5 clock going counterclockwise or it wont work it seems, you also have to connect it at the same torch Edit: scratch that I messed it up again by testing if I could connect it with a different torch. Edit2: fixed it when I post it ill show how exactly to run it.

Page Lock?
Hold the phone. Why did this page get locked? I try to go in to fix some cross-linking, and I find I can't edit. Has there been vandalism recently (I thought the naming controversy was good and dead). --Allus 20:32, 26 July 2010 (UTC)
 * it is still locked since that whole aspergite thing. --Kizzycocoa 21:14, 26 July 2010 (UTC)
 * Back now :) --Allus 10:42, 28 July 2010 (UTC)

Formatting

 * I put forth a suggestion that all the images should be like the XOR gate, I find it totally easy to understand with the top down view, and I think the other examples would benefit from a likened image. It also helps if all the images are the same style, and I find the style of the XOR gate and the RS NOR Latch images present the necessary information in an easier to understand method then the other images on the page do.--99.159.20.67 12:24, 7 July 2010 (UTC)


 * I just like screenshots better because they "proofs" that the circuits works. (The topdown torch could also be misunderstood in the topdown view images) And did you remove the RS NAND by accident? --Samonite 15:28, 7 July 2010 (UTC)


 * I added a master diagram containing most of the basic logic gates I could think of in the top down perspective, and gridded to show total area. It's under the "Gate Logic" header and spaced accordingly. Image is titled [[Media:StandardLogicGates.png|Standard Logic Gates]]. --Mwr247 21:20, 7 July 2010 (UTC)


 * That diagram is awesome! But there is no such thing as a "RS XOR Latch". Its called "RS NOR Latch" :P You also have to change that circuit to the updated version I uploaded. It fix a serious bug in the latch(A signal was sent back to the inputs). --Samonite 21:34, 7 July 2010 (UTC)


 * Bah, I wasn't thinking when I resized the text, accidentally typed it out wrong since it was right after the XOR's haha... I'll get that fixed, and update the layout to the working version as well. --Mwr247 21:37, 7 July 2010 (UTC)
 * You might also want to change the switches to arrows(green) and add output arrows(red). You also need letters of the different in/output of the latches(I suggest an in/output arrow with the letter in it). --Samonite 21:42, 7 July 2010 (UTC)
 * I just discovered another small error. Clocks aren't timers (http://en.wikipedia.org/wiki/Clock_signal). Therefore they should simply be called "XX-Clock" and not "XX-Clock Timer". I'll also rename the "Clocks" section to "Clock generators".--Samonite 21:59, 7 July 2010 (UTC)
 * Alright, I've fixed the XOR-NOR typo, updated RS NOR Latch diagram, removed "timer" from the clock, added green and blue colors for output and inverse output, and updated the legend to reflect this. Thanks for your help :) Regarding the input image: the switch implies any sort of input (as it says in the legend), be it wire or actual switch of some sort, and makes for a nice visual cue. Regarding lettering: I feel this overcomplicates the purpose of the diagram, which was to demonstrate how to construct the gates. While I agree with the indication of outputs and inverse outputs, they can simply construct the gates themselves to figure out which switch triggers what output, or refer to the alternative demo image in it's respective section of the article. If you still insist I'll do it though, since it's good either way I suppose. --Mwr247 22:39, 7 July 2010 (UTC)
 * I think it should be possible to replace every input-switch with a wire. That is not possible with the OR gate (and the In/output gate but is that gate even necessary?). The OR gate in the article will work(thats also why I use wires as in/output in all images). I'll update the AND, NAND and RS NAND Latch today. Should I also add the XNOR? I don't think we should add NOT versions of the "advanced" gates. --Samonite 11:33, 8 July 2010 (UTC)
 * The input/output was mostly filler, so it can go away. That's one reason I had reconsidered the input wires, being that wires and switches on certain gates operate in a different manner, so I suppose when I have the time I'll get around to changing for that as well. As to the gates, you made a new image of the RS NAND, but you took out the inverter at the end on the new diagram, and thus it's not a true RS NAND (when both are in the off state, the output is off in your model, when it should be on). You need to readd the inverters for it to work right. Finally, I agree that advanced gates do not need images for their inverse counterparts. --Mwr247 15:20, 8 July 2010 (UTC)
 * Didn't even really test the circuit. Just couldn't see the purpose the inverters and removed them :P I'll upload a new version soon. --Samonite 18:15, 8 July 2010 (UTC)

Even-Clock

 * Not really a huge deal, but if you change the end-nodes on the clock, they can have an even number: http://i.imgur.com/WJ2WI.png --Chariot 05:23, 8 July 2010 (UTC)


 * Please post a better picture of the clock because I don't believe in even-number clocks. Also, should delays be added to the wiki? A delay is row of an even-number of inverters which delays the signal. --Samonite 11:17, 8 July 2010 (UTC)
 * Here's a picture of the other end, I don't know what else you need, because the nodes inside are the same as the other clock layout. http://imgur.com/fLy9E.png I can't get the whole thing in one screen (it's a 10 second timer and it has 104 nodes), so I hope you can figure it out with this, it's really quite simple. Additionally, I'd like to add information about how many nodes are needed for x amount of time, but I'm unsure how to accurately measure it. For all I know, my ten second timer could be a 10.3 second timer. --Chariot 18:37, 8 July 2010 (UTC)
 * OK, I hadn't realized both ends were layed out differently, so the first picture was pretty unclear, but I can assure you it does work.--Chariot 18:45, 8 July 2010 (UTC)
 * Indeed. Even-number clocks rapidly reach a stable state, with half the torches ON and the other half OFF. Peewee223 17:26, 8 July 2010 (UTC)
 * Even-clocks do not pulse. As Peewee said, you will get half on and half off.  If it works as you insist it does, Chariot, then this is due to a bug in minecraft, and not an error on this page; I encourage you to be sure that nothing else is going on to cause the pulse.  This is because the pulsing is caused by using the output of a device that inverts the input, as the input to that very device.  So called "Even-clocks" do not invert the input, as an even number of not gates produce the same output as they receive as input, so this does not occur.  Also of note is that the speed at which the pulsing occurs is a function of the delay mechanic that is discussed in another section.  What "Even-clocks" ARE is a memory cell, since they can stabilize in one of two stats, and given particular input, the designer can set which one of these stats the system will have--that is, the R S NOR latch is identical to a "2-clock" with the appropriate inputs to flop it's state.98.111.90.162 23:44, 26 July 2010 (UTC)
 * While I agree that even clocks are possible I think it's best to keep the page as it is, and pretend they don't. They require more hastle to set up (for the ones I've seen) as you've got to bypass the default state which will represent memory like Peewee223 and the last responder suggest. However if for some reason you'd like to set one up just wire two adjacent torches (http://imgur.com/E5H3i.gif) to a switch/pressure pad and send a signal till the circuit is at a stable point then with the removal of the signal the circuit will pulse with two torches acting as one (the pair of torches acting as one changes in a leapfrog fashion every frame). Signal generated when lever turns off: http://imgur.com/0bQ2S.gif, http://imgur.com/rSMOn.gif, http://imgur.com/zpd3H.gif. --CALLUZUK 20:49, 7 November 2010 (UTC)

More Formatting

 * Should the pictures of the gates be in right or the left side? --Samonite 15:31, 7 July 2010 (UTC)


 * They should be balanced out. Until enough combinations exist and we get a table set up (which I doubt will happen soon), most should be on the right.  The RS content should have left-based images. --Arlnet 16:32, 7 July 2010 (UTC)

Delay/Nomenclature

 * Should something be mentioned about it actually taking time for the "electricity" to travel through wires, this can cause desynchronization in more complex structures, such as a JK flip flop or a seven segmented display.--Zaneo 18:15, 7 July 2010 (UTC)


 * I thought it was just my client lagging behind, if this is legitimately the case then a bolded (or highlighted in some other fashion) text somewhere before the gate section begins should mention this. --Arlnet 18:24, 7 July 2010 (UTC)


 * I think this kind of information should be mentioned together with Clocks. (And instead of saying "electricity" I like to use the word signal) --Samonite 18:29, 7 July 2010 (UTC)


 * I think it might be reasonable to change any references of 'electricity' to 'magic', considering that according to notch, that's exacly what it is, not electricty, magic. (I'm a bit too busy at the moment to find the exact postings, if anyone has them off hand, would they mind quoting them here?)--155.43.28.48 18:33, 7 July 2010 (UTC)
 * Lifted from another page.


 * A2:16:12  it is NOT copper, it is NOT thermite
 * A2:16:27  i can confirm it's magic
 * A2:16:35  Hey Notch, will we get electricity-operated trapdoors/hatches and arrow/object shooting blocks?
 * A2:16:37  and I haven't seen anyone say that the ore glows in the dark when you hit it
 * A2:16:50 Notch, it's been noted, actually.
 * A2:16:59  oh great. =)
 * A2:17:05  there will not be electricity
 * A2:17:27 Notch, what you've created is, by all discernable definition, electricity.
 * A2:17:54  electricity most certainly do not have free not gates. ;)
 * Although both are apperntly from IRC, so I have no idea if there would be any records of that for reference.


 * The quote from 155.43.28.48:
 * I think the Redstone Dust (which is, and always has been[*] the official name for the red stuff) fits fairly well with the pseudo fantasy theme of Minecraft, and it will certainly have more uses in the future, mainly for alchemy and possibly other forms of magic.
 * Yes he does mention magic, however "other forms of magic" was VERY likely to be referencing "alchemy" and not the redstone itself. Besides, pressure plates and buttons and levers do not sound like magical items by any means. --Arlnet 18:38, 7 July 2010 (UTC)
 * I think that we should use the term "electricity", even if that isn't what it truly is, just because it probably makes it less confusing for first-time readers. Maybe make a note that while it isn't actually electricity, it acts basically like it for all intensive purposes. Xymostech 04:13, 8 July 2010 (UTC)
 * I agree with Xymostech, we should call it "electricity" in the article, but have some mention somewhere, say the beginning, that it uses a magical current, not electricity. Also, it doesn't exactly act like electricity, you don't have to ground the magical current or stop it from traveling into other "input" circuits. --68.1.112.116 12:59, 8 July 2010 (UTC)


 * Does repeater deserve it's own picture/sub heading? --Zaneo 21:55, 7 July 2010 (UTC)
 * What do you mean by a "repeater"? Xymostech 04:13, 8 July 2010 (UTC)
 * Repeater is two not gates in a row, used to extend how far a signal can pass along the powder. --Zaneo 04:15, 8 July 2010 (UTC)
 * Yeah, I definitely think that this deserves its own section. Actually, I think that things that aren't actually logic gates (such as clocks, and this) deserve to be in a separate section, because they are very integral to Redstone circuits, but don't fall under the traditional "logic gate" title. Sound reasonable? Xymostech 05:25, 8 July 2010 (UTC)
 * I agree. What should the section be named? --Samonite 18:15, 8 July 2010 (UTC)

RS NAND Concern
I'm not sure if its broken or if the new update did anything, but the Logic Gate RS NAND Latch doesnt work properly. I made this to test it out and on it -Q is on but Q is not on, even though R and S are both on. The master switch is there only to save time. And from what I understand from the explanation, -Q and Q should both on. Is there a fix to it? --Lecount 21:17, 11 July 2010 (UTC)
 * You are wrong. It works just fine. When both inputs are OFF the outputs is ON :P Test it yourself here:  --Samonite 22:56, 27 July 2010 (UTC)

XOR Concern
I made an exclusive OR (XOR) gate (though I could've used an AND here, I just like exclusive OR) and where the levers go instead I put down redstone to lead it to lever. well the redstone went from the back (lever in diagram) then two tiles to the right then down to my lever, but the torch would stay lit no matter what I did, only until I removed the two redstone connected to the block (one off the back and the one diagonal) did it work again so it seems like having an active redstone line diagonal of a block (at least one with a torch on top and a torch on one face) disables the lever completely as the other lever will still trip the switch. Not sure if this is supposed to happen or if it's known it happens, but it's not on the page. I'm also not sure if it was fixed later and somehow retained in my client. --Enzer 08:23, 20 July 2010 (UTC)

Truth Tables
Should there maybe be a section with truth tables (a table showing the input(s) versus the outputs) for the logic gates? or maybe just have small ones by the descriptions? I'm sure some of us don't know how they work. I get a bit tired of switching between this page (to see how they're made) and Wikipedia (to see if I have the correct gate) myself. --The qwert 03:49, 24 July 2010 (UTC)
 * A small truth table somewhere in their description would be nice.--Samonite 22:48, 27 July 2010 (UTC)
 * Added truth tables. Someone double check them, please. --97.127.153.56 13:51, 28 July 2010 (UTC)
 * Nice :D I fixed the RS NOR Latch.. I know its the "forbidden state" but thats how it works. --Samonite 14:24, 28 July 2010 (UTC)
 * Yeah, I didn't remember how that worked and I couldn't pull up Minecraft to test it out (I died and my base is missing). Thanks! --97.127.153.56 15:41, 28 July 2010 (UTC)

Interesting page I have created
I have just created the page "Contraptions" where everybody could place their own creation(s) with the redstone, it can be found here. Hope you all apreciate.
 * It seems to have been turned into a Redirect link back to Redstone circuits. I'd love to see a contraptions page, though, showing off what has been done, not simply an explanation of the tools available.  You cant call a kid a carpenter if he just looks at his tools and says "wat". I might edit it later and give examples such as locks, wire-specific traps, and other machines, but I have recently been busy with other stuff (Touhou Project, Cave story :-) though. --Arlnet 18:48, 13 July 2010 (UTC)
 * I support this whole heartedly, except it should include other contraptions, like auto cobblestone makers and mob collector/killers. EDIT: I've written up a page, and ironically could not find anything wired, so I've put the other ones I know in. Megadog 23:21, 14 September 2010 (CDT)
 * I'd love a place to share non-basic redstone circuitry with others. the basics are great but its daunting to make advanced machines. my first major project i designed was a binary counter with a clock input that can be chained together to count as high as you want to, but i only got to 3 bits due to lack of redstone (so it could count to 2^3-1 = 7). --Cert 14:02, 16 October 2010 (CDT)
 * The best place for a Contraptions page would be in the Tutorials section. DannyF1966 00:21, 17 October 2010 (UTC)

Jk Flip Flop
You do realise a Jk has Q and Q! as well as a clock, then J and K. The posted is missing the clock at the very least. --Zaneo 12:15, 27 July 2010 (UTC)
 * I know that JK's have an inverse Q but to get it you could just add an inverter to the Q. The "real" inversed Q in the RS Latch was too hard to get. Should I extend the circuit to include the inverse Q? I don't understand the part about the clock. Can you explain that one? (Unclocked JK's exist if it was that you where referring to)--Samonite 22:45, 27 July 2010 (UTC)


 * I know unclocked JKs exist, i thought that clocked was more common, maybe make a note that this is an unclocked one? --Zaneo 02:16, 28 July 2010 (UTC)


 * Maybe. They are actually quite easy to make clocked. Just add an AND gate to the input. Then attach a clock to one of the inputs of the AND gate. You can do the same thing with the JK. Just use two ANDs.--Samonite 15:56, 28 July 2010 (UTC)

Diagrams
Regarding: "This page contains MCRedstoneSim diagrams for compactness and clarity of design." - I do not find those clear at all. After staring at the key for quite a while and even playing with the MCRedstoneSim simulator I still don't understand all of the icons. Could someone include screenshot of what each icon is supposed to represent, or can we switch to something easier to read? This, on the other hand, took a second but was otherwise easy and useful: http://minecraftwiki.net/wiki/File:StandardLogicGates.png


 * They are kind of confusing, but I think if i was actually in game and looking more at the guide I could figure it out. Maybe we could reupload screenshots of the gates.Toadbert
 * I second this. --Andrew12 23:25, 30 September 2010 (UTC)


 * Yes, I agree. The new diagrams are extremely difficult to read.  The in-game screenshots were far more helpful.  --Declare variables, not war. 03:16, 28 October 2010 (UTC)

the diagram key would be easier to understand if it used better colors to signify if something is above a block, below, etc. the very slight grey coloring is hard to distinguish between white/yellow--Cert 18:53, 16 October 2010 (UTC)

Long term clock?
Could anybody explain to me, how could be latch used together with a pulsar to create a long term clock? I want to create something with a 15 second delay...
 * Add as many t-flip flops to the end to make it as slow as you would like
 * On a related note, can anyone make the C version of the T-flip flip work?


 * i would not advise using a pulsar as clock. it switches too fast for torches to recognize.
 * i just built the 'c' t flip flop design in an effort to save space, and when the input is on it just acts like a clock and burns out randomly. --Cert 18:47, 16 October 2010 (UTC)

Gif files on main page
Hi, this is the first time I've contributed to a wiki, apologies if I'm doing anything wrong. I wanted to point out that the gif files for the redstone circuits aren't animating on the main page, and it's not obvious just from looking at the gif that some of the circuits are two or three blocks high. I was looking at the XOR circuits in particular. If someone tries to build one of the circuits in mcredstonesim just by looking at the gif on the main page, it may take them a while to figure out where they're going wrong. DannyF1966
 * This happened to me.
 * Andrew12 23:24, 30 September 2010 (UTC)
 * Ok, I updated the page to show that some of the gifs are animated. DannyF1966
 * Gifs on main page are ok now, so removed my notifications. DannyF1966 19:26, 16 October 2010 (CDT)

Max distance runs
I've done some experiments and found that the farthest you can get from a redstone circuit is 17.5 chunks (281 blocks). In other words, if a clock generator is placed in chunk #1, as soon as you cross the midway point of the 17th chunk it will cease operating. Important to note that it will not begin operating again until you are within 10 chunks (160 blocks). I have only tested this in one direction (North/South) so I'm not sure if a diagonal makes any difference - probably doesn't. That makes the largest redstone circuit design effectively 17x17 chunks (272x272x126). Smidge204 22:00, 9 October 2010 (UTC)

XNOR A not working
I've successfully built all the other gate types, but XNOR style A isn't working for me. It's behaving like AND instead of XNOR. Can someone confirm that the gate diagram is correct? --TaviRider 19:03, 16 October 2010 (UTC)
 * I cannot manage to reproduce any of the XNOR gates. Do any of them work? --bazzaNZ

Missing Logic Gate (For Completeness)
The truth tables made me notice the list of gates is incomplete. Some are on the list or are input-switched duplicates of those on the list: nor; not a; not b; xor; nand; and; xnor; A implies B; B implies A; or. Some are trivial: always off; b; a; always on. That leaves two possibilities (one and it's input-switched version): b and not a, a and not b. I know it's a simple gate, but it should be included for completeness; It's basically just invert one input, join inputs, invert if anyone can put together a diagram (or an 'and' gate with one input inverter removed).

Clock circuits?
They're working for me, but glitch out after a couple of cycles. I built one with 3 inverters, and it works at first, but then it glitches and stops working. Wolfos

Never mind, got them to work, the reason was that the framerate was too high, just enable "limit framerate". Wolfos

Updates on the gates?
There are more size/clock efficient gates out right now. Why are they not being updated? I just updated the VincentLaw flipflop because I kept referencing every time. Also more people should know about it if they are getting into these gates.


 * Can you direct me to a place with information about that? Like, what is it supposed to do? I cannot find any documentation about a "VincentLaw flip flop". I temporarily removed it, due to the bad formatting it currently has.


 * Also, sign your posts with ~ . Thanks! Riking 23:20, 27 October 2010 (UTC)
 * More likely than not it's because nobody has put in the effort to make another image with the gate as well as adding a new section. If you provide a source I'm sure we can hold someone at knife-point until they make one lol. --Moxxy 03:23, 28 October 2010 (UTC)
 * Is there a convention requiring that new versions of a gate be added to the existing image? And are animated GIFs required? I find them annoying and difficult to read (I often end up taking screenshots of each frame and referencing them individually). I want to add some more compact gate designs to the D and T flip-flop sections, but one is a 1x6x6 side view of a vertical design and the other is a two panel image (much like the section on the adders, but not nearly that huge). - Tallinu 07:50, 25 November 2010 (UTC)

Clock confusion
I think it would be great if the creators of clocks show how each tick corresponds to a real-life second. Presumably there is some relation? Sorry if this is a dumb question -- I'm new to redstone beyond simple logic and circuit hiding. PlasticineGuy 02:59, 1 November 2010 (CDT)
 * This varies depending on your framerate. From the "Redstone Facts" section: "If you get upwards of 100 FPS while playing Minecraft, a tick should equal about 1/16 of a second." The clock signal progresses around the loop by one torch per tick. The pulse width and period of the clock - the time it takes for any given torch in the clock to turn on or off, and then return to the prior state, respectively - is measured in ticks. - Tallinu 07:57, 25 November 2010 (UTC)

XOR Circuit Diagrams
I've constructed each of the diagrammed XOR circuits and can only get about half of them to work. I believe that they work when built properly, but I just can't understand the diagrams for B, D, and G. I really need a reverse-direction output for a situation in my game, but I can't get B to work for the life of me. Can someone post screenshots of a working circuit of type B? -- Ignirtoq 03:45, 5 November 2010 (UTC)
 * I have the same problem with D. You can look at the circuit diagram and immediately see that it will do nothing since the inputs aren't wired to anything. I'm working to figure out what the heck the author is thinking, but I'm not holding out much hope. .parliament 23:37, 5 November 2010 (UTC)
 * The D design chart indicates that D is used with levers, and the other ones are multi-level, so click on the picture to view the animation --Cert 03:09, 26 November 2010 (UTC)

Water and lava
I am sure water and lava aren't affected by redstone state itself, but because the redstone block state changed, it starts flow recalculation. Nickguletskii 10:44, 7 November 2010 (UTC)
 * Uh yeah, that's the point... 04:45, 7 November 2010 (CST)

Redstone Torch decay?
I have noticed while working with redstone circuits that redstone torches cease working correctly after they have been switched back and forth a few times (at least when working with plates/buttons, not levers), effectively disabling any machineries that contain inverters. What's the deal with that? --BlueLegion 08:52, 10 November 2010 (CST)


 * Are you doing this in SMP? if so, there is still some issues. --Fishrock123 08:57, 10 November 2010 (CST)
 * Nope, single player. Maybe its only on one savegame, im gonna try it on another one. --BlueLegion 19:20, 10 November 2010 (UTC)
 * Tested it and the redstone torches are "glitched" on other saves too. After a couple of times the state has been switched, it makes an extinguishing sound (like when water hits lava) and the torch wont work for a few more times switching the state of the redstone circuit. With a lever, this bug will occur pretty fast, but it will fix itself after a few more times switching. With a button it takes longer until the torch gliches, but i have not yet "unglitched" it by switching it more. --BlueLegion 19:38, 10 November 2010 (UTC)

Just sounds like you are switching them too fast and they are burning out --Cert 14:53, 25 November 2010 (UTC)

Binary Counter
I have a binary counter set up that seems pretty simple... It's just a counter, a couple T Flip Flops and some AND gates. And instead of drawing out a diagram for every single piece (it is more than a few, I assure you), you could show how the outputs of the pieces should be connected. It's pretty simple once you have the T Flip Flop, Counter and AND gates down.
 * 1) Counter connects to the T Flip Flop (A), our 1 value, and presto, you can count from 0 to 1.
 * 2) The output also goes to the next T Flip Flop, (B). This is our 2's slot. You know have a binary counter that goes up to 3.
 * 3) The output from A and B go into the AND(a) item. The output from that AND(a) is sent to T Flip Flop (C), our 4 column. It is important that the output from A and the output from B are the input to the AND(a) gate.  If you invert to extend the length, invert back again. Also, the output from AND(a) must be the input to C. I can't stress this enough.
 * 4) Now that you can count up to 7, it is time to add the next piece. You use the outputs from sources AND(a) and T Flip Flop(C), and plug them into the next AND(b). The output from that connects to T Flip Flop(D). You can now count to 15.

That's as far as I've gotten, but you could follow the same pattern and potentially make it longer. The problem is, I use a 5-timer and the 8 column is *just* changing by the time the 1 column changes for the next number. You would have to have a timer that runs even longer than that. Or condense the counter somehow that I overlooked this early in the morning, so that there isn't so much delay.

Please respond with any comments, questions and concerns. -unsigned comment by Chevnoir 12 Nov 2010

advanced circuits
seeing how there are more advanced things being put up on the main page, are we able to post advanced circuits for people to expirament with? I think there should be a venue for these kinds of things so every person who wants to design more advanced circuits doesnt have to reinvent the wheel. I have been designing a 2 player tic tac toe board that has unique control components i would like to share, and also start seeing anything else other people make. should there be an 'advanced circuitry' page to contain these? and also move the binary / adding machines on the main page to the advanced page for clarity? thoughts? --Cert 10:12, 25 November 2010 (CST)


 * I think thats a good idea. Perhaps something like Redstone_circuits/Advanced_Circuits or Redstone_circuits/Complex_circuits? Metalhannes 16:28, 25 November 2010 (UTC)


 * Great idea. -- prettycoolguy (talk) 19:32, 25 November 2010 (CST)


 * [[File:switch.png]] This is my switch idea. While S is off, once A turns on, Output 2 (O2) will turn on indefinitely until the reset (R) switch is thrown (the two Rs should be connected by a bridge, as they should be reset at the same time). Likewise, while S is on, once A is turned on, O1 is turned on. The purpose of this design is that once A is activated, it will check state S and divert the signal accordingly. If S changes while O1 or O2 are on, nothing changes. I used this in a tic tac toe board game I am making. If a pressure plate is hit, it checks whether to display an X (S off) or an O (S on), then sends the signal down the line to my display (and also to change the value of S). So once its someone else's turn, they press a pressure plate and the opposite signal is generated.--Cert 22:13, 25 November 2010 (CST)


 * wait, is this just a more complex D flip flop? I dont understand the D and JK flipflops. They are poorly worded. --Cert 15:22, 26 November 2010 (UTC)


 * I've reverted your edit related to this, User:Metalhannes. It needs to be discussed more first. Those circuits are not really 'more advanced circuits' and it certainly doesn't belong in the hatnote.  I do agree that the adder diagrams do not belong here, but also, User:Cert, I don't think there is much reinventing required if you, say, want to make your own adder.  The whole concept of how it works is well documented elsewhere and implementing it using the previously documented Redstone logic gates is trivial. -- prettycoolguy  (talk) 14:46, 26 November 2010 (CST)

Well the page now is too big. It is more advanced because the Redstone circuits page is about logic gates and latches and such. If I would want to build a circuit I'd check here first to see how logic gates are done in mc and check the advanced circuits to see if anything like that had been done before. Nobody voted against it and you even said that it would be a good idea yesterday. I talked with User:Kizzycocoa here who basically said go for it.

If it's a name thing we could name it something else I don't care about that. But I really think that circuits like these don't belong on a page where the very basics are being explained.

And if you think that the adder circuit doesn't belong here why did you put it back? It's still in the Redstone_circuits/Advanced_circuits page so no information is lost.

Metalhannes 15:32, 26 November 2010 (CST)

The page is getting unwieldy, but I reverted that edit mostly I guess because I disagree with the presentation of it and the naming. I shouldn't of left the adder though, was just reverting.

I'm thinking that it may be best to simply put this information on the mechanisms page? Also, the "Circuit Applications" section here should be removed when we make this change as well(or merged somewhat with Redstone (Wire)).

-- prettycoolguy (talk) 23:08, 26 November 2010 (UTC)


 * I would start a new page for the "advanced circuits" because the mechanisms page is big enough as it is. Though the tutorials  section is a good idea. People are more likely to contribute more  cicuits so we would just have moved the mess to another page. I also  agree on moving the Circuit applications scetion. The advanced circuits  page has to be deleted then of course.


 * I would also move the electronic applications section from there to this new page to  make a clear distinction between physical mechanisms and electronic  ones.


 * The thing why I'm so in favor of starting a new page is, is that it is easier to find information on smaller pages (if  they have been categorized and linked properly) than on a few big ones.


 * Metalhannes 23:28, 26 November 2010 (UTC)


 * Yes, certainly. What should the page be called?  Maybe tutorials/Electronic_Mechanisms like the sub-section on the mechanisms page? tutorial/Redstone_Mechanisms? I don't really like either of those, but they would work. -- prettycoolguy  (talk) 00:35, 27 November 2010 (UTC)


 * Tutorial/Advanced_Redstone_Electronic_Circuit_Systems! :P I have no clue I'm terrible at naming things but since electronic mechanism is already used I think we should go with it, I woudln't worry to much about it though as long as ppl know what to expect when they see the name its sufficient. Metalhannes 00:48, 27 November 2010 (UTC)


 * Heh. One more thing to consider is, what about the much more basic Redstone things on that page? like the 'land mine'? Guess we should just leave those on the tutorials/mechanisms and take only the combination lock(as these are 'advanced').   I'll start moving things over now.. -- prettycoolguy  (talk) 01:15, 27 November 2010 (UTC)


 * I agree :D . Youre doing a great job. 19:31, 26 November 2010 (CST)


 * Thanks -- prettycoolguy (talk) 01:53, 27 November 2010 (UTC)

Major Changes
Previously there were obnoxious, inconsistent images, the structure was confusing and generally I found the article to not be as accessible or usable as it could be. I have gone ahead and made some significant changes. I was going to call it a 'rewrite', but the majority of the previous text has been retained. My objectives were to emphasize accessibility and readability, modifying anything in the way.

The main changes are:
 * Pictures
 * I have added clear, consistent screenshots of all of circuits(..Is this really a good word to keep calling these? I'm thinking 'Digital Mechanisms', 'Electronics', 'Electronic Components', or something would be better...).


 * Layout Reformatting
 * Previously there were 'repeaters' listed as 'Logic Gates' and all sorts of other stuff. There are now three main sections for these 'circuits': "Logic Gates" - Actual logic gates, "Latches and Flip-Flops" - This section is largely the same, and finally "Other Electronic Components" where I have placed things such as clock generators and repeaters.
 * I would love to make little defaultly-minimized boxes to hide all of the additional circuit designs, so that it is not in the way everywhere cluttering the page, but I don't believe this functionality is enabled on this wiki :(


 * Rewriting.
 * I mostly liked the quality of the writing, but some sections have been touched up for accessibility and readability. If you disagree with my choices then feel free to rewrite anything, I appreciate it.

I spent a good chunk of time on this and would be grateful for any comments or criticism you have. Thanks.

Oh, and one last thing, sorry if I accidentally removed some of your additions, Tallinu, I've been working on this since yesterday. Just add it back if did.

-- prettycoolguy (talk) 19:32, 25 November 2010 (CST)


 * Could you perhaps upload new pictures at a better angle? These are a little more clear but it is harder to see all the parts going into it,  however if you were to be about the same distance away but made yourself  a few blocks off the ground so we could see how everything went in that  would be great. --User:Bosnity
 * Yeah, these are the third revision of those pictures, I just couldn't get things perfect. xD An overhead view would be better, but I'm not up to screenshotting it just yet.  I believe they do a fairly good job though for their purpose. -- prettycoolguy  (talk) 03:47, 26 November 2010 (UTC)

Offloading Basic Information to More Appropriate Pages
I've put some of the more basic fundamental facts about how Redstone wires function on the Redstone_(Wire) page and linked it instead of being here. I do not believe this should be part of the scope of this page, it is large enough already. -- prettycoolguy (talk) 19:32, 25 November 2010 (CST)

Delay Circuits
Can anybody get these to work? I could not. - prettycoolguy (talk) 19:32, 25 November 2010 (CST)
 * Yeah, i got the smaller one working. Didnt try the larger one. Takes awhile to get used to the picture graphs --Cert 21:27, 25 November 2010 (CST)
 * Alright, I'll try again. Certainly does take some getting used to with those diagrams. -- prettycoolguy  (talk) 03:47, 26 November 2010 (UTC)
 * A north-south orientation of the alternating stacked torches reduces the delay to 1 tick instead of 2. If being used for delay purposes, east-west orientation is recommended, unless attempting to fine-tune the delay - such as when making synchronized double doors. - Tallinu 00:17, 27 November 2010 (CST)

Transmitting power vertically
I'm experimenting with some advanced locking systems for my tower, and I'm finding that I need vertical power transmission. To transmit a state vertically upward is easy: I alternate redstone torches and solid blocks vertically, for a space of approximately 1×1×N, where N is the height required—the input may need to be inverted at the end, but that's trivial. A similar 1×2×N design exists that might be useful for isolating input at multiple levels, where torches placed on the sides of blocks are alternated in direction at each vertical level. For greater speed, a 2×2 vertical helix of redstone wire can be used, using the 1×1 or 1×2 repeaters where necessary. Both designs are internally navigable for towers with 2×2 interiors: the 2×2 has just enough space to serve as stairs, and the 1×1 can be used with a ladder inside the shaft for an interior of 1×2.

To transmit a state vertically downward, I find that I need a 2×2×N vertical helix of blocks with redstone wire on each, delaying the spiral's descent 1 block for inverters when necessary. However, this design has the problem that it's not internally navigable if any inverters are used—is there any way to get around the problem without making the tower interior 2×3 or bigger? I want to create tubes that are as small as possible so as to conceal them properly within my architecture, and proper exteriors would have to be 4×5 at minimum—too big. Should I bite the bullet and leave them unnavigable? It's easy to build, but if water got in, I'd have to rebuild it completely.

I think this would be an interesting topic for this page to cover. What do you think? &#123;&#123;Nihiltres&#124;talk&#124;edits&#125;&#125; 05:38, 26 November 2010 (UTC)


 * Besides a spiral/staircase design, the best way I've come up to transfer power DOWN is a series of floating blocks with redstone on top and a torch on the side. The torch on the side will recieve an inverse signal and transfer that state to the next redstone dust underneath it. This results in 2 blocks down for every 1 blocks across. NOTE that this can be spiraled as well to conserve space, but i stretched it out so you can see it

For transmitting up, a series of floating blocks with torches on the top will invert its power to the floating block above it, so you can transmit signal straight UP. Also be aware of the lag the inverters will cause. If you want a lagless up/down signal transfer, you have to resort to staircase designs. Please feel free to use these images to create a wiki article, or improve on them if you dislike. --Cert 08:58, 26 November 2010 (CST)


 * Ahh, your down-transmission method is exactly what I was looking for. It means that—besides the input, of course—a downward transmission tower can be 1×2! That's excellent. Thus, we have the 2×2 "fast" spiral staircase design for either up/down that is a navigable 2×2, a 1×1 "slow" system for up-repeating, and a 1×2 "slow" system for down-repeating. In a tower with a 2×2 interior, that means we can easily alternate staircases with vertical repeaters and ladders, for navigable 2×2 transmission towers in either direction. There may be some trickiness with output direction, but that should be trivial to work around. I'll document this properly soon, probably as soon as I've got my lock system working with the vertical down-tower it needs. &#123;&#123;Nihiltres&#124;talk&#124;edits&#125;&#125; 14:49, 26 November 2010 (CST)


 * Somebody has added this to the page, I think it should be moved to Redstone though. -- prettycoolguy (talk) 21:01, 26 November 2010 (CST)


 * I just added it; feel free to move it, but please leave a reference behind. In either case, this page ought to be split into subtopics; it's easily the largest page on the wiki. &#123;&#123;Nihiltres&#124;talk&#124;edits&#125;&#125; 21:05, 26 November 2010 (CST)


 * I think with the recent addition of Tutorials/Advanced_Electronic_Mechanisms, which took a lot of load off this page, the page is in ok state. What I would like to do though to make it more skimmable is add collapsible boxes for all the extensive alternative circuit designs.  I'll have to ask an admin about adding that functionality xD.  -- prettycoolguy  (talk) 22:20, 26 November 2010 (CST)

repeater as a capacitor/backflow preventer with latches
I am not sure of the exact terminology, but I havent seen anything mentioned that repeaters should be used with 'memory cells' (like RS NOR latches) to prevent the wire into the latch from becoming always on... which is a problem if that wire runs to other gates. Anyone understand what I mean? --Cert 09:13, 26 November 2010 (CST)
 * Yeah, but I think thats common sense. Metalhannes 13:53, 26 November 2010 (CST)


 * In electronics the term is a 'diode'.  Should be noted that[in case you havent read the whole article], many of the designs note whether they 'compromise' the inputs. -- prettycoolguy  (talk) 20:38, 26 November 2010 (UTC)
 * Keep in mind that you can take an output wire directly off the torch for isolated output, or an input wire straight to the block for isolated input. NOR latch design A shows this, at least in the diagram.

Compact parallel wiring commented out?
It seems to me that if ways of moving a signal up and down are acceptable subjects for this page, this topic should be as well - it's definitely not something that everyone would find intuitively obvious. Perhaps a better screenshot is needed to go with the edited (but still commented out) text? One which doesn't suggest packing in 3 wires for every two horizontal spaces? Generally, one isolated wire per meter of width is compact enough while also relatively easy to unpack or use with 1-wide circuits. However, mention of how to stack repeaters should still be included in case someone wants a more vertically oriented bus, or to layer multiple buses atop each other. Thoughts? - Tallinu 04:41, 27 November 2010 (CST)


 * Yes, if moving up and down are acceptable... I commented that out when there was no such thing there, but that is not a real solution.  What needs to happen is find a page for little things like this or a section. something.  When that does get re-added though, note that integrated repeaters force the cable to have required increased vertical size so that the torches don't interfere with each other and corrupt the data. -- prettycoolguy  (talk) 04:58, 27 November 2010 (CST)
 * As long as the torches are on the sides of blocks as shown in the repeater section and are all at the same point along the cable, lined up in neat rows, it works fine. They will power the blocks above them, but there won't be anything attached to those blocks. Torches attached to another block's side won't experience interference. Only wires and upright torches, attached to the block under them, are affected by that block. - Tallinu 07:16, 27 November 2010 (CST)
 * Oh ho, you are correct, yes. Didn't fully test that. -- prettycoolguy  (talk) 22:30, 27 November 2010 (UTC)
 * I've suffered from DNFT syndrome myself on occasion. ;) - Tallinu 05:37, 28 November 2010 (UTC)

MCRedstoneSim diagrams header
Is there a way to make Template:Mcrs_diagrams fit to the right of the TOC instead of forcing it up or down so that it can use the entire width of the page? The TOC really needs to be on the left so that the thumbnails for the logic gates and NOT sections don't get pushed down out of alignment with their sections unless Template:- is used, which adds too much white space. - Tallinu 05:36, 28 November 2010 (UTC)
 * For readability the TOC should be on the right. The images should ideally go next to the TOC. I can't think of a way to get it to do that though. We could always get rid of the TOC temporarily. at 23:45, 27 November 2010 (CST)
 * I'm putting the toc back on the left as the way it pushes down the images at the moment makes things much less readable. -- prettycoolguy (talk) 17:11, 28 November 2010 (CST)
 * (Tried to post last night but the site was down or something...) I don't see why the TOC on the left would affect readability at all. All the wikis I've seen always have it on the left, and I think inconsistency hinders usability almost as much as having the thumbnails orphaned from their proper sections. On the other hand, Wikipedia doesn't put any text next to the TOC. Perhaps that would be a better solution?
 * - Tallinu 00:23, 29 November 2010 (UTC)
 * He was talking about having the TOC as float left, so the text would wrap around it making the text harder to read. I've seen many a long wikipedia article that as the TOC moved over to float right so it isn't stretching the page heaps. at 18:25, 28 November 2010 (CST)
 * Okay, TOC on right sounds fine then. Just need to fix the giant MCRS diagrams and overlapping tables.
 * - Tallinu 00:34, 29 November 2010 (UTC)

Too many Frames instead of Thumbs, tall images now wasting space
With most recent edits, two problems appeared. Frames are being used for many images larger than thumb size as well as smaller, which results in a great deal of wasted space (especially in the XOR section). And several sections have overlapping (unreadable) tables - the mix of float:left and not floating seems to cause that. I'm going to make adjustments (but the TOC seems acceptable now, and the MCRS header and logic gates picture in the center look good). - Tallinu 00:34, 29 November 2010 (UTC)
 * Wrong, it was always like that. Thumb resizes images based on width, not height so you have to manually set a thumb width if they're too  tall. The tables were also always like that, and the only way I could  fix them is to have one under the other or put them both inside a table  so I left them for now.  at 18:34, 28 November 2010 (CST)
 * I know it's width-based. However, the width of some of the images that were in frames is greater than the default thumb width. Maybe they were already like that and your edit just brought it to my attention? Anyway, as mentioned, all but those smaller than thumb size in the right margin are now thumbs, and the tables no longer overlap.
 * Also, feel free to undo the repositioning of the MCRS info box if anyone doesn't like it.
 * - Tallinu 01:18, 29 November 2010 (UTC)
 * Ultradude25, look at the AND and IMPLIES gate pictures, for example. They are wider than the pictures above and below. They are marked "frame". Those above and below are marked "thumb". Marking them all marked "thumb" shrinks them to the same width. When an image is shrunk due to being too wide for a thumb, whether it's a specified or default width, the height is reduced.
 * And it's not possible to save a page without getting a preview of it, nor did I simply scroll to the bottom without actually looking at the differences - I previewed the results of my changes multiple times as I worked in order to make sure it was doing what I thought it was doing, and it was.
 * The reversion undid the fix I applied to the overlapping tables, in addition to the (not made-up) change to the images, by the way.
