Let's say I have a 5x5 wall that has redstone torches on each block on one side:

a 5x5 cobblestone wall with redstone torches on all blocks

Is there a redstone circuit that would allow me to power every block in this wall, so that all torches turn off ?

I'm pretty new to redstone, so forgive me if this is obvious.

Good question. I don't know if you can with a full 5x5 block - my initial answer would be no, but I'll try to come up with a solution. –  Kevin Y Mar 2 '11 at 6:42
    
I think the response is no. I'll give it a few try before confirmation. –  Lysarion Mar 2 '11 at 9:31

Related note: it is possible to power a wall made of dispensers, because they "may be triggered by redstone wire placed up to one block adjacent to it as well as running directly into it; therefore a single redstone wire can trigger up to 5 dispensers in a cross pattern." minecraftwiki.net/wiki/Dispenser –  Denilson Sá Mar 2 '11 at 11:03
    
The best I can get is every one off except for the middle 3 of the middle row. I hate "no" answers, but I think it's the case. –  Kevin Y Mar 2 '11 at 15:16

@Ronan, right now I'm only interested in all of them together, however the ultimate goal would be to draw shapes. –  David Thibault Mar 3 '11 at 0:11

I don't think it's possible, to power a block you need a wire running towards it, which it won't if there is another wire next to it (it'll turn into a corner, rather than a straight line, or a T if there is another wire on the other side).

Repeaters have a specific direction, so you can make a row of them 'towards' the blocks, but they can't be stacked vertically. –  Kevin Reid Mar 2 '11 at 13:55
    
@Kevin how would you power the repeaters positioned like that ? –  David Thibault Mar 3 '11 at 0:09
    
Kevin Y's got one idea, and there are probably others. –  Kevin Reid Mar 3 '11 at 12:01

Here's my best attempt. It lights everything but the middle 3 in the middle row, and you can control each torch independently with clever uses of repeaters to isolate circuits (not in the way I have it screenshotted, though): enter image description here enter image description here enter image description here

Thanks, I actually learned something from this :) –  David Thibault Mar 3 '11 at 4:28

At best you could do it with three rows using Redstone Repeaters or the classical checkerboard pattern using standard wires.

If you want to use redstone repeaters, you can make this pattern (showing the back of your wall):

If you want to use strait wires you can make this pattern:

How would I power the repeaters? As far as I know wires also need to be pointed at them. –  David Thibault Mar 3 '11 at 0:07
    
For the second pattern, how would I place wires like that? if they are sitting on a block, they will link up with lower levels right ? –  David Thibault Mar 3 '11 at 0:08
    
Actually I think I get the second pattern, as the wires won't run through the diagonals (I'm not sure I'm being clear but I don't know how to phrase it!) –  David Thibault Mar 3 '11 at 2:57
