Redstoners, unite!

I know there are a few of us who already do redstone circuit building, and a few of us who are starting off, and a few of us who would like to,

so here's a thread soley based on sharing and gathering information on building the biggest and best contraption out of redstone, whatever that particular contraption may be.

For all those people who would like to get started, a few useful links are:
http://www.minecraftwiki.net/wiki/Redstone_circuits
http://www.minecraftforum.net/viewtopic ... 35&t=25695
Also, to test your redstone circuits without worry of lack of space or redstone, and to take pictures of it and post here, you'll need:

At the moment, I'm concentrating on Combo Locks, as it interests me.

I've made a system which bases itself around RS NAND latches, forcing itself to lock if a button is pressed in an incorrect order...
meaning the door will only open if the buttons are pressed in the correct order.



This is a slightly tricky one, as 1234 is a lot easier to build and easier to work with:



However, if someone manages to get those three in the right order by chance, they also might hit any one of my trap switches, which I trap using this:



With the button on the left being the power which will instantly lock itself, and the button on the right to un-lock it. You can also replace the switch on the right with a button, to make it faster.

Lastly, a modified RS NOR latch, Giving the lock switch (top left one in this case) complete power, meaning as long as it is on, the out current can not be changed from on position, but if it is off, then it may change from on to off freely (useful for having a switch on the inside)



and this, ladies and gentlemen, is what it all looks like together.



(of course, the door will be in such a position to block out people, but RSS can only have the door facing one way)

This means that to open the door, the top left one, then the bottom middle one, then the bottom right one must be hit, and only in that order.

The top middle, the top right, and the one between that will lock the entire system, forcing the door closed.

and the switch on the inside locks the door closed.

RSS estimates this takes 376 redstone, 68 torches, which is equal to a whopping 444 redstone ore (as long as each ore only gives 1 redstone, if it gives 5 each you'll only need to mine about 89 ore.)

RIGHT

now its your turn, let us see what you have made :D

:shock:

Seriously, some of the people playing this game need to be electrical engineers if they aren't already. Nice work Valk! How much are you going to charge to build one of these? :D

Just the redstone required to build it, and any sticks for torches and pickaxes to clear the space (I'll provide the cobblestone for it)
I have about 2 and a half stacks of redstone ATM, and I have a lot of iron I can trade for more if need be.

I do it for fun, I enjoy building and creating, and I LOVE fiddeling, my dad is a software engineer, so I guess it's in my blood to fiddle :p



*edit*

I hope this doesn't come across as a thread to show off, I had more an idea of a place to gather and exchange knowledge and ideas and hints and tricks, etc.

Valk these are really great. I love doing redstone even though alls I can do is make a lever door :oops:

Hehe I might look into redstone more as I am really intrigued by something like this to be in a game like minecraft. Nice work aswell Ill have to get you to hook me up with one of them sometime ;)

I'll certainly try :D cheers :)

it's certainly a lot of fun, and there's a lot to learn.

Suprisingly Wikpedia has a lot of information to help, although the images don't help as much, the knowledge is still there, along with a few other sites. Google is your friend.

Hrrmm.

So here's a tricky bit.

I am requesting help, from all you knowledgable folk out there.

I'm trying to design a circuit that if:

(A) input is turned ON, then the circuit will lock, where
(B) input is turned ON, the circuit will un-lock, but
the output remains OFF.
if (B) is turned on AGAIN, then
the output will turn ON, and will stay ON.


if just (B) is turned on, then
the output will turn ON, and stay ON.

Been picking at my brains over this, now it's time for some zombie action and to pick at yours. Any Ideas?
if you have any questions, feel free to ask.

One last thing, it would be prefable if the output was a RS NOR latch, but not impossible, don't worry if it can't be done.

Any ideas, or part of the contraption, would be more than appreciated.

Thanks :)

I can imagine the system itself will be small and simple... hopefully... but I'm just not entirely sure how to do it.

Just combine a large series of logic gates - Some levers will provide power while some will not.

I think you misunderstand. I'm not trying to build a combo-lock, I'm trying to build something else.

It's for a trap, so you can walk out of your house (walking on the pressure plates) and not set it off, but once you (or anyone else) walks back in, then the output turns to on.

Oh - I thought you were talking about combo locks.

You could have memory cells, hooked up to an RS NAND... That oughta do it.

Which memory cell? RS NOR and RS NAND are both memory cells (I think).

Hrmm.. interesting. I could try it. Thanks.

if you have an idea of how to do it, a screenshot would help ^_^

An RS-NAND is just an RS-NOR with inverters on both the inputs and outputs

I'm aware of that, but they both seem to act differnetly.

For instance, RS NAND will stop sending a signal if it stops recieving the signal, whereas RS NOR will take and hold the signal (at least the desgins I use)

Valk can you explain exactly you want the circuit to do, as in opening a door or something? I can work on it in single player to design it if I can figure out what you're trying to do with the circuit.

It's for an alarm system. I've got the design of the alarm (all three stages of it) down on Redstone simulator, if you want me to post it.
The basic idea is that you hit a switch, allowing you to walk across the pressure pads (persumably to exit the room) without activating the alarm, and when the owner (or more importantly, someone you don't want in) enters (and stands on the pressure pad) then the alarm goes off.

hmm - that's strange, the wiki entry on the logic gate I thought I knew isn't there.

You can have an XOR gate, hooked up after a AND gate which connects to your alarm, essentially acting as a saftey switch but I'm not sure about your idea. =/ I think I know the circuit but I can't know for sure.

I think that I built something similar for my combo lock, but i cant remember how it went now, will have to wait for the old map to come back to check it out.

It was just a standard combo lock on the outside, but inside the door i put a "master switch" which would hold the lock open or closed (can't remember which now).

If you want I could try build it on single player and upload the schematics

on macmacs castle, I've got a master switch (especially modified RS NOR latch)

How could I explain it better... hrrm..

I have an alarm system, which looks like this:



Doors represent note boxes.

(big, I know, I just haven't got around to compacting it)

Somewhere between the NOR latch and the inverter (although the space can expand easily), I would like (and am trying to make)

a machine, which (I can find is the simplest way), only sends an on output when turned (from off), on, off, on, but only when it recieves an input from an exterior source (the button you press to get out)

I have a feeling D-flops might help... just not sure. Sounds like something the D-flop might do.
