Tutorial/Automatic Cobblestone Generator

This Cobblestone Generator can be used as a substitute to Energy Collectors to supply Energy Condensers with EMC. This process can automatically generate and supply something with a certain material, for example, generating Ice for a Nuclear Reactor. This method still used EE in the form of the Energy Condenser, but for those who feel Energy Collectors are "too powerful," this is an equally powerful, but much more time and space consuming alternative.

Materials
This design can be created to absolutely any size, creating just one cobblestone block every 2 seconds, or hundreds. For the purposes of this tutorial, all data will be for this design, which is  8  blocks long.
 * 8 Block Breakers
 * At least 8 Pneumatic Tubes
 * 68 Glass Blocks (assuming you're building it exactly as listed in the tutorial)
 * 2 Buckets of Water
 * 2 Buckets of Lava
 * 8 Red Alloy Wire
 * 1 Timer
 * Some sort of recieving block for the cobblestone to flow into, e.g. a Chest or an Energy Condenser. For the purposes of this tutorial, it is an Incinerator.

The Heart of the Machine


First things first, what makes this thing work are Block Breakers. These Redpower2 machines will, upon recieving a redstone pulse, break whatever block is in front of them and send it out the back. If there is Pneumatic tubing there, it will be automatically sent to an appropriate location via the tubes. If there is not, it will simply be ejected and dropped on the ground. Place your 8 block breakers in the ground, as pictured. Make sure they're in a straight line and directly adjacent to each other, as pictured.

Containing Everything


For the purposes of the tutorial, we use Glass blocks, so we can see what's happening, but this can be made out of anything that stops liquids - even Fence posts, if you really want to. Place your blocks in a two-block-high rectangle around your block breakers, with one empty space to each side of the breakers, but no space at each end of all 8, as pictured.



Then place a line of your blocks above your block breakers such that there is one block of air between the breakers and your blocks. The picture will help to explain:

Watch your Step!


Place 8 blocks to either side of the breakers. These blocks are temporary, so that the water and lava can spread out, rather than dropping straight down - you'll be breaking (and losing) them in a few moments, so make them something expendable, like Dirt (Pictured is smooth stone).

Now, the number of Lava buckets you'll need will vary depending on how long you make your cobblestone generator. For an 8 block long generator, like this one, you only need 2, but for a 16 block long one, you'll need 4 buckets. The reason is because, as pictured, lava only flows 3 blocks out from the source block, and doesn't form new source blocks, like water does. So, for this 8 block design, you have to place two separate lava source blocks to cover the entire machine. Of course, you could just go out and get 8 buckets of lava, instead, but it's up to you.

Then on the other side, just fill the entire thing up with water. Using two water buckets, you can create infinite source blocks by placing one bucket, then placing the other two blocks away. This will create three source blocks. Fill your buckets from the middle of the three, then rinse and repeat to fill as large an area as you like. Your generator should now look as pictured to the right.

Now go Underground


...Because working above ground is too mainstream. You'll want to dig out directly underneath your block breakers, then one block to the side, so you have a 2x2 tunnel underneath the whole cobble generator, as pictured. It's probably best to dig under the water, rather than the lava... just a suggestion.



Then place your Pneumatic Tubes underneath your breakers...



Now get out your red alloy wires and place them on the ceiling directly next to your block breakers. If you didn't know they could do that, now you do. They can also go on walls and between Microblocks and all kinds of cool stuff. Place your timer on the ceiling as well at either end of the wire... yes, the timer can go on the ceiling too. Don't worry about the breakers activating - the pneumatic tubes shouldn't be connected yet, so the breakers won't actually send the cobblestone anywhere, they'll just hold on to it.

And to Finish it Off


...place any extra needed Pneumatic Tubes to connect the block breakers with your chest / condenser / incerator of doom and the block breakers will automatically begin sending your cobblestone to its destination. I've found the best time to set the timer to varies greatly depending on lag, location, length, and probably a half-dozen other things. For example, this specific setup, in singleplayer, on this world, runs at 1.550. A 16 block-long one on the specific SMP server tested can only run at 2.250.
