Talk:Tutorials/Hourly clock

Why can't I put up this page. If I cant put it here then where. I mean, maybe it could be a link in advanced circuitry or something, but still... –The preceding unsigned comment was added by Fireglo450 (Talk 12:34, 05:54, 2011 August 5. Please sign your posts with
 * I second that we keep this page. As far as I can tell there is nothing on this wiki that's even remotely similar in form or function. We have perfectly pointless lava-traps against griefers, that any player can easily outrun. There are descriptions of piston-mechanisms that lock chests, which can be bypassed with bare hands. I see no reason why there should be room for such useless contraptions but not for clocks - for which quite a variety of uses exists as shown on the page. However, it would be nice to expand the article with some blueprints and maybe videos of some of these clocks in action, but all in good time. After all, this site is only a few hours old... --Yatsufusa 07:44, 5 August 2011 (UTC)
 * Totally agree with you Yatsufusa, this tutorial has just as much value as the others (probably more), but I think the issue was that it wasn't prefixed with tutorials/
 * The layout on this tutorial is great. I think there is a cheaper way of doing this: [Addict] Qcdynamics 21:37, 5 August 2011 (UTC)
 * Thank you everyone who supports me. I have screenshots pending, but, not having access to youtube, no videos can be added. I will try to do step-by-step visual aids and some diagrams. I hope your lobbying will save my page. fireglo450 6:57 p.m., 5 August, 2011
 * I appreciate your suggestion Qcdynamics, but I can't use youtube videos as help. I need a link to somehing on the wiki or forums, or written instructions. --fireglo450 5 Aug, 2011 11:14 p.m.
 * If you can't link to youtube because you're not yet an autoconfirmed user, I can give you a hand with that, just let me know what video(s) you'd like to link. I just made a BlockGrid tutorial (User:Qcdynamics/BlockGrid_Tutorial) which should help with diagrams. (If it doesn't make sense, let me know) Qcdynamics 20:11, 6 August 2011 (UTC)

Sooner or later someone would have proposed a Clock with a 7-segment display anyway, so I took the freedom to do a first draft. If someone with some expertise in redstone circuits knows a good tutorial and/or schematics for 7-segment displays and decoders, please add it to the page. While I could google one, atm I have no way of determining whether it is awesome or garbage. --Yatsufusa 02:08, 8 August 2011 (UTC)
 * I skimmed through the video you linked and it seems pretty standard. This guy knows his stuff when it comes to redstone, and he has a really good series of tutorials on 7-seg, decoding. He was making a computer, but it could just as easily be hooked up to a clock. Qcdynamics 05:24, 8 August 2011 (UTC)

Automatic Doors
While I appreciate the thought I just put a pressure plate on the first block behind any door (on the inside of a structure), so it closes automatically behind me and opens by itself when I want to leave. So the only click needed is the one when I enter. I can't tell how common this technique is, since I play mostly singleplayer, but there will be neither a cow nor a creeper in my living room and nothing will shoot at me through any door accidentally left open.

I appreciate any idea tossed in, but to me this one seems a little redundant because there's already such a cheap and efficient solution. (Yes, I see the irony writing something like this on a page for building ingame clocks out of tons of redstone!) On the other hand I could be very stylish to have doors open and close by themselves while no one is near. Opinions? --Yatsufusa 15:33, 6 August 2011 (UTC)
 * Your technique to put a pressure plate adjacent to your doors is very common and way cheaper. When I first read this idea, I was thinking that someone would be making a bank with a time-lock delay on mulitplayer. Qcdynamics 20:11, 6 August 2011 (UTC)

more efficiency by using frequency dividers
Please, handle with care! I'm just starting with redstone circuits‎ in Minecraft and my description might be a little confusing to some.

You can use a T flip-flop as frequency divider to slow a given frequency down. One flip-flop slows the frequency down by the factor 2 and therefore dividing the number of repeaters needed by 2. Using a second frequency divider will slow that frequency down to half speed again - slowing the original frequency down to 4 times the original frequency. Three by 8, four by 16 and so on...

I'm not familiar enough in the whole subject matter to tell if every kind of T flip-flop described in the wiki will do. The cheapest one that seems not to be based on some sort of glitch uses 16 redstone totals. As example: You could do the 75-clock with 10 repeaters instead of 75, which saves 147 units of redstone dust (195 from the repeaters minus the 48 for 3 flip-flops, not counting any redstone-wire you might need to properly connect all the parts). That's quite a lot of digging you don't have to do. --Yatsufusa 19:04, 7 August 2011 (UTC)


 * I'm not a super great redstone circuit guy, and also I used SPC and did no digging except maybe to put the circuit underground. Screenshot instructions are coming, everyone! --fireglo450 5:54 p.m. Aug 7 2011


 * That's not a bad idea, using a small clock and scaling the output. I'm not sure a T flip-flop would do the trick, but it depends how you're wiring it. This is probably the cheapest one I'm aware of, but it uses a sticky piston which means different resources. Qcdynamics 05:24, 8 August 2011 (UTC)
