it slows the engine TNT down so it doesn't move out of the water and blow your cannon up.
Ah, that makes a lot of sense. You'd probably only need it under the final squares of flowing water though, right?
That is correct. That way the rear-most TNT Boosters are pushed towards the front quicker. The Soul Sand just secures the boosters from going out of the water (resulting in a crater).
Also, for people that want to fire more then once with just pressing one button, use this:
By pressing the button once, it sends out 5 different signals (shoots a cannon 5 times) and automatically resets itself. You would, of course, need to make the clock on the bottom bigger, this one was for demonstration purposes.
I came up with this idea awhile ago, and even though I could make the booster TNT launch correctly, I could get the actualy projectile to work, so if anyone thinks they can do it, feel free to.
I just hate how large they are, makes it hard to use on ships. So, I was working on making a smaller and more compact cannon...and I did. It was about 4 blocks long and 3 wide, but it had a range of about 20 blocks if timed right.
In the Alpha thread, there was a long-lasting topic called "Noobcake Labs (cannon science)" where Minecraft TNT Cannons were discovered and experimented with. While that thread had long history and information, I do not find any similar thread in the new "Beta - Survival Mode" topics.
I would like to make this thread as a hub for other Cannoneers to display and share their works for the advancement of Minecraft Cannon technology.
Now, I feel kinda bad that I cannot provide any decent information about a "Basic Minecraft Cannon" (you can YouTube it and literally pull thousands of results) as a First Post to softly introduce newbie Cannoneers to our projects.
So I will borrow a video made by YouTube user: Darkthero
to display how a Basic Minecraft Cannon works.
Last where we left off in the other thread, we had been playing with water based timers, same-plane cannons, and other fun stuff.
Recently, I posted two videos about my cannon: The Imperial Avenger.
I had built 3 variations of my Imperial Avenger: the A Series, AX Series, and MinImperial Series. However, I fire the AX Series' cannon, which has a redstone delay timer and an add-on which allows the capability to adjust it so a TNT Missile is activated (and explodes) early.
And part of the recent experiments, I have also created a "same-plane" cannon which the Engine and the Missile exist and function on the same plane. Giving the advantage of minimal flying arch (even below that of a half step).
Anyway, I'm reviving that thread so cannoneers, new or old, share your creations on this thread and let's help each other out.
A guy named keirshar made one just like yours, your just using the same idea.
I just had another idea. We need to figure out what causes TnT to fly more upwards, and if we can find that out, how to make it mortar-like, and easy to build, so that they can potentially be used in SMP for sieging cities.

Wouldn't raising the firing platform and timing the cannon's firing for the peak of the projectile's ignition jump do the trick?

TNT propellant falling together directly next to the TNT Warhead will increase arch. Moving the propellant farther back from the TNT provides less boost, but also less arch. A balanced combination of arch, power, and proper Warhead release timing is necessary for an accurate shot.

I just wanna know if anybody's tried the longer ranged cannons in a server. Will the TNT explode when it reaches that 300 block range?
Due to the warhead fuse and the (possible) entity velocity cap, I think it's impossible to propell a TNT warhead farther than approximately 225-250 meters. Unless someone can verify otherwise, that is. No matter how much propellant you use, you can't overcome certain physical limitations.

I don't know if anyone knows this, but I experimented with torch delays and found that 39 torches between the switch and projectile is just the right amount of time. (This is assuming that there are no torches between your propellant and your switch. Example: If you had 2 torches between your switch and your propellant, add 2 torches to your timer)
I made a SUPER long range cannon using the above and only 24 TNT for the propellant.

I use 13 TNT for 200meter shots.. What do you consider "Super long range"?

Greetings fellow cannon smiths and believers in the powers of the dark mysterious powder. I just wanted to show off my cannon after trying several designs I found this one to have the most promise for me. The unique part about it is that it can be aimed precisely over a large area in front of the cannon. The booster bay is also three wide, which adds power and also aiming abilities. From the pictures there is no redstone on the center row of tnt because they are ignited from underneath by redstone torches. This design has some serious potential for making a cannon that fires a full 360 degress, I just haven't unlocked that power yet. Alright time for some specs. This cannon can be fired with only 2 booster charges and up to 21, but can be increased infinitely albeit at minor gains. Nine tnt shoot up to 200 meters and a full load needs a timer and height adjustment to be viable. The only thing this cannon is lacking right now is a timer and proper projectile loader and height adjuster. I hope you guys gain something from this design and look forward to seeing what you guys can cook up. Cheers.

Etho has created a 360 degree cannon on our SMP server with a variable timer on it like mine. It's impressive when fired, to say the least. I think he's posting a video of it soon.

Confirmed that ground friction acts on the TNT if it is launched from a block instead of the air. There is approximately a 30 percent loss of velocity if the TNT's launched from a block.
Also, I'm working on a new megacannon:
The fountain thingie at the bottom, holds the projectiles. One quarter of the cannon holds around 250 booster TNT. Aimable in all directions. I originally planned to have no arc, but after finding about the loss of velocity from ground friction, there will be a SLIGHT arc (time in the air will be constant).
Can't wait to see the distance on that. But slight arch is actually good. If anything fired straight and horizontally, the missile would be already acting on gravity, resulting in less distance as well.

Conundrumer managed to nearly hit 1000 meters of distance with one of his mega cannons (recorded in the "Noobcake Labs (cannon science)" thread). I'd consider that "Super Long Range". I think your cannon is a good accomplishment of a mixture of using a timer adjuster and other logic gates. I only managed to set the timer with 2 switches (reference: Imperial Avenger AX Series), but when facing the cannon in another direction, I saw a massive loss of distance but less arch.
If I were you, I'd definitely look into compacting it all.
In a battlefield, that cannon looks like a large mass of area to defend. Two cannon shots into your area (same direction, etc) would completely sabotage it's functionality.
Oh, I forgot to mention that it'll be right under the sky ceiling, bounded by a box (I'll make it out of glass for demonstrative purposes) and protected by waterfalls, along with the bottom being made of obsidian.

I'm interested in understanding more about the effects of slowsand on TNT cannons. Please explain.
