I became bored waiting for the 1.8 update, and I recalled people on my last thread asking what exactly you could do with a redstone computer. So, I decided to put together a very basic redstone game, a game of chance if you will.

The concept is very simple, you pick one number out of the eight possible. Then you drop the metaphorical ball onto the metaphorically spinning metaphorical wheel and hope it stops on your number. Only in this case, the ball is a signal that toggles some memory latches, and the wheel is several mine carts operating on different timings attached to a series of T flip flops to ensure 0's and 1's are just as likely for each binary digit.

Without further ado, here it is:



And now... on to the specifics!



How do those numbers get so random, you ask? Well, it all starts here, where mine carts zoom around loops of different lengths of track and different amounts of powered rails. This ensures that each mine cart has a different amount of time between each activation of the detector rail.



Next, we have those T flip flops I was talking about. They keep the numbers un-biased, while giving the user a ridiculous amount of lag at the same time!



This piece of space age technology sets the memory latches. The doohicky-jobber at the top is basically a monostable circuit, only inverted. It needs no more than a 1-tick off-state pulse so that only one set of data makes it through. The torches turn on, acting as a clock line would in a D flip flop, saving whatever data is in the inputs. The pistons run off the same signal, but have a 2-tick delay, otherwise the pistons would extend back down before the torches would turn back off, saving nothing.



This byte of ROM serves as the controls for the game. The two levers at the left you never touch... EVER!
If you do, you pretty much just broke the game and nothing happens, they're simply pieces of data that operate game mechanics, randomness, number display, and such. The next three levers, that are up, do absolutely nothing. The three levers on the right are how you choose your number out of the eight possible, 0 - 7 (000 - 111)



This is where the data comes directly from the computer. (Remember those two levers?)



These are the lines that your chosen number are sent through, LSB to MSB from this view. (1, 2, 4) They go into one half of what I like to call the dual-decoder. When the random number side is low the signal is passed into a piston in the number display. But, the chosen number side can only be low if the random number side is also low, this is how it determines if you won the game.



Here is a better view of my patented "Win Detection System". Right now it is hooked up to a bunch of nothing. But eventually, when I'm in the mood to hunt spiders, I will make some dispensers and put something in them.



This is the number display. I couldn't get the whole thing in one shot because I didn't give myself enough space and the room is very cramped.




Well, there you have it. It's nothing too extravagant, but I just wanted to show you guys some cool things you can do with a redstone computer besides counting and math. Tell me what you think, give me some criticisms, and hopefully even shoot some ideas at me for what I should do with my next computer. (Which will be a lot more powerful.)

Just wondering. How did you get that much flatland in xbox 360 edition and that much redstone?

I duped the redstone, diamond, iron, and gold blocks. Somebody else flattened the area.

Wow that's really cool! The fact that you can make a computer in this game is awesome, but applying it to do something else is just amazing to me. Nice work! (That's an understatement.)

A few more of these, and you can make a Minecraft casino.

The game was actually pretty easy, it only took around three hours. The computer itself was a pain, I built it over the course of a month. You should check out the original thread or the video, you can find the original thread with a detailed explanation by searching: "First Redstone Computer Ever Built on 360" To see the video, you will have to go to my profile, and it will be under topics, near the top of the page.

this is defiantly not the xbox edition unless you've modded, you are in super flat and also in creative. But other than that, this looks pretty good

Not super flat, the flatland area is only 235x218 and on MCXBLA there is no level.dat, region, anvil, or any type of separate file specifically for the world data. So, even if I wanted to use MCEdit, I couldn't. And I'm not sure where you get the idea I'm in creative mode, that's also not possible.

Thanks for the interest, everyone. Any ideas for future computer add-ons?

Adding a desktop with a mouse to drag icons
Pretty sure this would either be impossible or make your computer 10x bigger.


Before he started making the computer and I lost my Internet (till this Friday!!!) and got banned from the forums for no reason.
I saw the land he has. It's only 1 block thick and is pretty massive.
I saw that he answered your question, but he forgot it wasn't one person who did that. It was like 8. Lol, 1 person would take way too long.

I'm sure it's possible... but I'm definitely not doing it LOL. You would need your own texture pack with an invisible block to make the mouse cursor look right. After that point, I'm not even going to try to figure out how to accomplish such a feat. It's so much harder to make a redstone computer user-friendly compared to a calculator. So I just leave everything complicated. The game is pretty simple though, all you have to do is input your guess, load the program, start the clock, and the computer does the rest. I forgot to mention this in my OP, but the game runs extremely fast too. From the moment you start the program, it takes just over 6 seconds to generate a random number and check your guess. Then another 0.3 seconds to reward you if you're correct.

Yeah, my point was just that I didn't flatten the map. If I linked to the original owner of the map I would probably get an infraction. No clue honestly how many people helped flatten it, I do know there had been at least 10 on the world before I used it though. But several of those people probably only helped with blowing up mountains and such.
