Cave Crawl II: Electric Boogaloo

[Mr. Analog]

So you know that water and redstone don't mix, not even side by side.

RP2 would definitely make this easier and prettier.

Anyway, I think we'll need a switch on both sides, otherwise we'll never be able to get in the castle!

Yes, the same as glowstone.

The idea here is to build the pistons under the water and have them raise sand upward.

I'll play around with some configurations in creative mode.

[Thorin]

Yeah, we're on the same page as to where the pistons go.  At first I was thinking of only one block of sand going through the two layers of water, which would cause redstone to be near / in the water.  Then I realized we could do a stack of three or four sand so that the pistons and redstone are buried in the ground under the water, thus eliminating the problem of redstone near water.

I think the "mechanical room" with all the redstone and stuff should be accessible and its interior should be lined with sandstone and lit up so that we can show off the redstone circuitry.

[Lazybones]

If the "bridge" is only one block under water this isn't that hard, there have been tutorials on it for ever using levers.

If you want it to be auto magic, I would put pressure plates at each end and hide a toggle ( retracts once you reach the other side) circuit deep under ground or a timer circuit (stays up for a limited amount of time..

[Thorin]

This is in water two blocks deep.  But Mr. A's right, it should be easy - just put the pistons deeper in the ground and use a higher stack of sand or gravel on top of them, then the redstone is away from the water and it's no big deal.

[Thorin]

I think I figured a mechanism for the drawbridge last night, in single-player.  One of the problems I encountered was that if the pistons move too fast, the sand breaks instead of falling.  I have a piston-based T Flip-Flop with one input and one output that leads into an ABBA switch with two outputs, the first leading to the lower sticky pistons and the second leading to the upper sticky pistons.  I made a little three-wide two-deep stream over the mechanism to try this out and it worked good, with the sand simply replacing the water blocks when it was pushed up.

Would you mind if I built this, Mr. A?  I've got this grandiose plan for a colour-coded mechanical room...

[Mr. Analog]

Go for it!

Redstone is super fun to play with

[Thorin]

The drawbridge is done.  There's a button just inside the gate.  Go ahead and push it and see what happens   Then push it again, and see what else happens

Ooh I'll check it out tonight!

[Thorin]

Lemme know what you think about the mechanical room, too.  I tried to make it bright and cheery in there, and I was digging directly under the moat so had to be careful when digging up (almost drowned once).  I tried to make sure that we can reach all the redstone, pistons, etc without having to break any blocks.

Sure maybe I'll log in now just to see.

[Mr. Analog]

Drawbridge pix!

We need to name this fortress at some point

[Thorin]

Third pic, just to the right of the entrance you can see a sandstone block - the button's on there.

[Mr. Analog]

Also yeah I think we have to widen the moat and I will design a more grandiose gatehouse (complete with flaming braziers)

[Thorin]

How wide you wanna go?  Five blocks?  I have a couple of Efficiency V diamond shovels that I'm happy to use up

[Mr. Analog]

I propose a long jump to figure it out!
