Tutorials/TNT cannons

This TNT Cannon was originally made by Spidiweb7. All credit goes to him. However, after the 1.7 update the original TNT Cannon that was created by Spidiweb7 does not work anymore. There is now a TNT Cannon that works with the 1.7 update. The credits go to RomanPanda.

TNT is an explosive in Minecraft. Using that, Water and Redstone can be a deadly combination. These cannons can be designed in different ways. Some are made for long range needs, and there are some that can shoot in multiple directions.

There also other entities in Minecraft that can be propelled by TNT as such arrows that are attached to one of the projectile TNT, which can rain arrows down on the fields, or even arrows that are attached to the booster TNT itself. The latter can be used to propel multiple arrows at a target, and has several advantage over the dispenser/arrow turret traps. This includes propelling several arrows at the same time without large scale redstone circuitries and a large number of dispensers. However, it can be expensive due to the cost of TNT, can be dangerous if executed incorrectly, and needs manual loading after every salvo. However, a sophisticated system of redstone circuits and dispensers full of arrows can create a incredibly deadly weapon- a remote-firing, long-range grenade launcher cannon, complete with incredibly deadly shrapnel as an added bonus. It can prove useful in multiplayer sieges, as the explosion blows a hole in walls, then the arrows kill anyone not murdered by the explosion. And then there's a hole to fire another one into! You can smell the carnage just reading about it!

A picture(of the non-dispenser and arrow version) can found here at noobcake labs.

Animal/Human cannon
Very dangerous. You probably always die. You can place a transparent block (e.g. sign) on the block where the TNT would go to shoot yourself. If you are wearing full diamond, the initial blast will not kill you, but the fall will if you don't land in a deep section of water. However, by hacking to gain infinite health, you will be able to survive.

Superlarge Cannons
All cannons can theoretically be enlarged continuously, but will exponentially get bigger in base area needed, and will become more and more complex, with redstone timing circuits. Bigger cannons also serve no purpose except for decoration, or for shooting yourself very large distances, as a smaller cannon serves the same purpose

New kind of cannon (with mod)
This is a new kind of cannon that can shoot many TNT blocks at once, but requires a mod (http://www.minecraftforum.net/topic/328725-18wireless-redstone-v14/).

First, build a structure like this:
