Over the last week or so, I've constructed an (almost) fully operational 3-bit calculator in Minecraft. It can currently add, subtract, and multiply, and, when i get around to making it, divide.

I've decided to mark up a cartograph for you guys to help you understand it.

(if that's to big, go here)

1: This is where you and the console are, reading the instructions is suggested. This is the only place you need to be.

2: This is the seven segment hexadecimal display. Unfortunately, it only works for addition and subtraction, it has no support for multiplication, you will have to use the binary display for that.

3: An older version of the display. It works faster then the other one because it closer to the circuits, but it's no where near the console.

4: This is the binary to hexadecimal converter. It takes the binary answers and makes them usable for the hexadecimal display.

5: The addition station. Adds your numbers together.

6: The subtraction station. Subtracts your numbers.

7: The multiplication station. Multiplies your numbers.

8: A more powerful calculator i built that only does addition and only displays it in binary. You can check it out if you want, i used a fly mod to get there.


Download link

Just download, unzip, and place in your saves folder.

Problem solutions

1: If it doesn't work at all when you first open it, flip all the switches on then off. The redstone sometimes glitches up with MCedit and this usually fixes it.

2: Read the instructions in the map, you may be operating it wrong.

3: The seven segment display is hexadecimal, so when it comes up as A, B, C, D, E, or F, it's not a glitch.

Any problems, glitches, ect, just ask me. And for the third time this post, read the instructions in the map.

I made something new, its just a simple trading system.

You put an item in, other guy puts an item in, you each press a button, and the item is pushed to the other side. The torch under the glass shows whether or not you pressed the ready button. The button near the water is the ready button. The button in the corner cancels the ready button in case you accidentally pressed it. The pistons are just to control the water flow and make sure you can't jump in the water after it starts to flow.

Here is the wiring. Its pretty simple, just 2 RS NOR latches, and AND gate and 2 things that convert an endless pulse into a short pulse, I forget what they are called.

Can you scale down or crop the pictures before putting them on here they are massive but from what I see that is a pretty cool idea.

I'm currently working on making an arena that has waves that are timed so a new wave starts after a certain amount of time it's taking ages to sort out the redstone but it should be epic when I'm done.

Nope. They always come out like that due to the high resolution of my monitor and I'm too lazy to adjust them.

And I thought my sand generator was genius.

So I started a new calculator. My goals for this one are the following

1) A modular design

2) All decimal input and output

3) More powerful (4-bit)

4) As small as possible

What I've built so far follows complies to all four of those rules.

That is just the Input panel. It takes a decimal input, converts it to binary and stores the number. Unlike the last one, this one also uses buttons instead of levers. So its coming out amazingly, and so far its very fast. Even though I'm trying to build this smaller though, it still may be bigger than the last one because its more powerful and it needs to do decimal conversions.

Finished the multiplier. Did not come out modular like i had hoped.

Adder and subtracter are finished. Also finished the 7-segment display

I'm ditching the 7 segment display for multiplication answers (again). The only way i know how to do it would involve separately programming every single number (and you can multiply up to 225 on this machine).The total size of a piece like that would more than double the size of the calculator currently. So, once again, I'll make a 7-seg for addition and subtraction, and a binary display for the 8 bit numbers you multiply.

Scratch that, I'm not giving up the 7 segment display for multiplication. I originally thought there were 225 combinations I would need to build for. I was tired and frustrated then. Now I did the math and there are only 89 combinations to program, and I've already done half of 30. It'll take a while, but its doable.

Eh, I'm getting lazy. The addition and subtraction parts of the calculator are completely done, the multiplication display isn't finished. Controls are fairly obvious, find the buttons, use the lever to change which number you're changing.
