    Indeed. I built a functioning cube almost a year ago response to a challenge. I never got around to adding a randomizer although it wouldn't be hard to do. A solver however would be extremely difficult to build.

    Quote from Conundrumer

    Just saying that there's already a few instances of 1km shooting cannons. For example: *snip*
    I actually built one that shoots 2 km. Here are some stats:
    TNT | Distance, in meters
    19 | 285
    38 | 600
    57 | 785
    76 | 810
    114|1385
    133|1565
    152|1610
    170|2065

    Unfortunately, due to its complexity, it's pretty unstable (and has room for lots more TNT), so I can't really call it the longest shooting cannon yet. It'll still need a lot of tweaking before I release it.
    You might be able to find my old cannons in the "TNT science revived!" thread somewhere in the survival section (I also posted a link to my TNT physics thread on page 2 of this thread). One used 76 TNT to shoot around 1 km. Unfortunately, they don't work anymore due to water not pushing TNT. But the technique of separating horizontal boost from vertical to prevent airbust that allows theoretically unlimited range still works.

    But anyways, good luck getting your cannon to hit 1 km. It's so satisfying.

    I've already managed 1 km+ with one version, but like yours it's very unstable. The longest shot fired 4 TNT ~1.5 km from ground level using 72 TNT. I'm a huge noob when it comes to TNT cannons BTW; I've just been throwing stuff at the wall and seeing what sticks, so managing to improve runnerman1's design at all has me pretty chuffed :smile.gif:. I think I'll go learn me some TNT science now...

    Holy, that is amazing, please send me a schematic so I can work on it even more.

    I exported it with the TNT in place so you can see how it's loaded. Note that 4 of the payload blocks are obscured by the other 5 (the ones under the pistons). This version has some minor modifications; the payload condenser is simpler and the range is now about 800m, but the payload tends to spread out a bit more.

    That's quite a clever design!

    I've managed to improve on it quite a bit by adding more layers and such. The latest revision fires a payload of 9 TNT about 750m, but there's usually 1-2 TNT that fall short. It's much larger and consumes a ton of TNT though; 57 + payload per shot. There's likely to be room for improvement still; 1 km might be possible with a bigger charge, and there's room for more payload.

    Clicky for some pictures!

    Edit: Here's the damage from one shot, from 7 TNT traveling 760-770m.

    I've been playing around with this design a bit and (mostly) solved the breakage problem by adding a simple automatic boat landing pad. It also makes it easier to refill the dispenser; just put the boats down on the pressure plates. I made an automatic launcher using a similar design, but with stone pressure plates and a connection to the dispenser so that a new boat is swept onto the launch pad after yours gets launched.





    Edit: And a shot of the landing pad and launcher in place:

    Here's a design with minimum delay, less resources and takes up less vertical space.

    FYI, this isn't the first working Rubik's Cube. I finished a few days ago and submitted it but for some reason Conundrumer's video got approved first and promoted.

    Eh.... How did you get Digital Diamond when I made the first working design and submitted my video first? Mine hasn't even been approved yet.

    If you can get your cube to run faster and more consistent than mine, let's collaborate and make this :|

    Hah, now that sounds like a real challenge! Especially since I never learned how to solve them.

    once again nice work for the people making rubik's cubes! but i really want to see one that you can see on the outside!

    If the cubelets are visible from the outside instead then you wouldn't be able to see all of them from one spot so you'd have to run around the cube just to get a good look at the state. I think that would get annoying really fast.

    Anyhow, good job on getting yours done Conundrumer! I don't think the glass is that bad; the floating cubelets look kinda cool. It's certainly a lot faster than my original design; though I am working on redoing the edge rotators to speed mine up (got a rotation time of about 6 seconds now with no cooldown between rotations).

    Edit: My new edge rotator uses the same mechanism as yours. The control circuitry is completely different though.

    Your lighting in there is really dark. (Can be fixed)

    It looks fine in-game. You only really need to be able to see the colors properly.

    I have no idea what button dose what. (And it could be hard to explain on a sign)

    The vertical faces are controlled by the buttons in front of them, left is clockwise.
    The top and bottom faces are controlled by the buttons in the corners, left is clockwise when looking from below.
    I might replace the black blocks that the buttons are attached to with colors corresponding to the center block of the face that they control.

    The floor messes up and you can fall through it, when you move it.

    It's actually ok if you're standing on any part except the one that I walked onto in the video :tongue.gif:.

    Being inside the cube make's it harder to see, because the cube is so small.

    There's no way you can see the faces from outside since the wiring and pistons obscure everything. I think it's better anyway since you can see all the faces without having to run around.

    The center block on every side dose not move, taking away convenience for the player.

    The centers in a Rubik's cube aren't supposed to move.

    Anyhow, I've managed to shave about a second off the turning time. Wiring is still a mess though!

    Finally finished mine. It's a bit slow, but it is bi-directional so it's tolerable. The edges are the slow parts, being 9 cycles of 11 ticks; most of those ticks are from the signal extenders in the wiring loops powering those pistons but I should be able to shave a tick or two off anyway.

    Haven't had much time to optimize the wiring so it's still a huge mess :tongue.gif:.

    Features:
    - Bi-directional rotation
    - 90 degree rotation time: ~11 seconds
    - Controlled from inside the cube
    - 5x5 faces on an 11x11x11 cube
    - Total size: 38x37x31
    - Mechanism uses 222 pistons: 27 per face and 10 per edge

    I'll upload world and schematic once I refine the design a bit more.

    Decided to give this a shot. Since I'm completely bonkers I'm doing bi-directional; I've managed to get 1 side working fully and 4 sides partially. The wiring is absolutely gargantuan! All up there's 222 pistons with 120 control wires.

    I put together a quick preview video showing the functioning side:

    The video looks cool, how do I view the schematic?

    The schematic is for use with MCEdit (link). If you just want to look at it you can make a new world and import the schematic into it.

    Managed to refine the design quite a bit. The raising cycle takes half as long as it did before due to improvements in the control circuitry. The wiring also takes up less space now, but it's still quite large. Reliability hasn't improved though.
