Currently working on something probably beyond my abilities, but meh.
What I'm working on is what I thought would be a booby-trapped nether portal, for servers like 2b2t where people could potentially come through your portal into your base and fuck shit up.
So what I thought I'd do was make a piston contraption around the portal so that when "de-activated" pistons would cover up the entrance so that the portal itself was sealed, then pistons from up above would open up and let lava into the portal area so that when someone came though, they'd get burned to a crisp. Then when the portal is "activated", the lava flow is stopped, pistons push into the portal area to clear out any remaining lava, and the portal area opens up again for re-activation.
Unfortunately on top of it being rather difficult to miniaturize at this point it also turns out that lava will shut down the portal if it occupies the same space as a portal block, and I'm not sure what would happen if someone tried to come through in that case. I'll have to experiment further.

Basically yeah, with the added bonus of hopefully deep-frying any unauthorized douchekazoos who would enter though it.

Jesus elephant-rimming Christ, that's insane.
I mean seriously I fought with redstone for like 6 hours the other day trying to make a 2x2 door and it's still convoluted and ugly as hell.

Well, that was a bust. I traveled through the nether, made a new portal, ran back, activated the booby-trap on the main portal, walked to the other portal in the over-world, entered, walked to the main portal, it was activated. Went through, and it spit out a new portal not far from the main portal.
Oh well, it was a neat idea at the time.

It would be better to use items despawning as the timer.
I made a piston door once. It takes up about 50 blocks of space. The opening is 1x2, and you can see pretty much all the wiring and pistons. If I were to cover them up I'd get a huge dome full of redstuff and cobble. I'm proud that it even works.
Took about an hour to make a 5-button combination lock with an "On-lock" lever that keeps the door open on two certain conditions (too complicated for me to explain at 12:48 am). Additionally, I added redstone torches above each button that reflect the value outputted by the T Flip-Flop that its respective button is hooked up to, so that you don't have to guess what the current values are.
Because I used buttons/T Flip-Flops instead of just having levers, it's a lot more wiring than absolutely necessary; but I, personally, think it's much cleaner looking, and much cooler looking. Plus, I learned more this way.
It's very satisfying to have completed this using no tutorials (save for the schematics of a piston T Flip-Flop (saves a lot of space; It's only 2x3x4). I keep telling myself that I'm going to build an ALU, but I can't bring myself to start it, considering I really don't know jack shit about that kind of thing. Well, I do, but I have no idea how one would go about implementing it with redstone.

You've crushed my pride completely.
I think I'm gonna add a bunch of t-flipflops to my combination door, now you won't have to expose the code.
To bad I fucking suck with redstone. Redstone is one of the many things that just make me feel stupid, It doesn't seem all that difficult really, but whne I try to do it I can never get the shit to work :p
Damn, Somebody here needs to PM their privet-server IP and teach me how to do shit. (Or we could just piss off)

I think a series of tutorials on how to not suck horribly at redstone are in order, I can barely get two doors to open at the same time.

It took me less than a week to get to the level I'm at with redstone now, and I've made a huge amount since. I just recommend following video tutorials and experimenting. Get a huge flat map and build like crazy.

I'll see if I can squeeze every important aspect of redstone into a 10 minute video. It's probably possible.

Inventory full of Tnt in a landscape full of redstone and switches. Didn't end so well.
This thread is moving so slowly, I think we ran out of pistons ideas
(It uses pistons for the T Flip-Flops, so that's reason enough for me to post it)
(plus bragging rights)
10 button combination lock, this time with a proper save-input and a display for each button that tells you whether it's currently active or not!
[t]http://i.imgur.com/WfX28.png[/t]
That's from the front. As you can see, everything is easily able to be concealed. Just fill the gaps, and make a very large building around the guts.
[t]http://i.imgur.com/C5MeY.png[/t]
The guts of the machine. Most of what can be seen here are piston T Flip-Flops, AND gates, and long lines of redstone connecting it all.
Took me about 2 and a half hours total, with no tutorials (save for a video on how to make a D Flip-Flop). The concept is actually really simple; it's a bunch of T Flip-Flops hooked up to AND gates. Incorrect signals (AKA the wrong combination numbers) are inverted, so that they need to be off for it to work. All of this is fed to a D Flip-Flop, for the save input, and then bused underground to the door.
Oh, and the best part is, the combination is very easily changeable (though not automatically; it requires manual editing of one small part of the machine)
(Also, this isn't meant to be practical, it was purely for fun. I know this isn't something you'd do on an SMP server without cheats.)

Actually, to make this more piston oriented, I might replace the door with a piston trapdoor... thing.

Attempt to create 4-piston clock.
Am I doing it right?
You need to put the redstone so the current hits the piston facing the block.
So I made this block sorter thing... it'll take any moveable blocks and put them into one of three categories; conductive, non-conductive, and gravity affected.

how does it tell non conductive from conductive. I understand the gravity part.
[QUOTE=Waffle99;31843044]how does it tell non conductive from conductive. I understand the gravity part.[/QUOTE]
There's a redstone current attempting to go through the block. If it can't, nothing happens, and the block is passed on to the next category, if it succeeds, it powers a piston that pushes it into the other category
I haven't used pistons yet, but I probably will for making certain levers power certain segments.

Ehhhh essentially yes but what happens exactly is that there's a repeater that powers the block-to-be-sorted, and if that block is conductive it passes the current on (like you said) which then causes a sticky piston to extend and retract with the block in hand before the sticky piston that takes the non-conductive blocks can retract... sorry, just wanted to clarify.

Ooooh what is that? I mean, where's the display? Or, is it a work in progress? Sorry, it's just that displays are the one thing I've never gotten working quite right and I love seeing fully functional ones.
It's functional. The display itself is on the other side, that's just the wiring from each segment.
Because I got lazy, I labelled the inputs for which segment it powers.

There it is, the other side.
Now I gotta go back to doing stuff for Monday. That took up the better part of an hour :v:
