16-year-old Makes Working Scientific Calculator in Minecraft

It's a working graphing calculator inside Minecraft. Doh.

To be honest, some of us barely have enough time to build a pyramid or towering 8-bit video game character in Minecraft much less a gigantic, functional machine that can be used here in the real world. Yet it's amazing to see these massive projects show up in video demonstrations where players build virtual machines brick by brick, especially from those who can't even legally vote.

Case in point: 16-year-old "MaxSGB" has created a working scientific/graphic calculator inside Minecraft. On a virtual scale, the functional device is enormous -- enough so that anyone in the real world would become a red blot of meat and bone staining the road if they fell from the very top. Honestly, his virtual machine looks more like a giant cargo ship ripped from a sci-fi movie than a working calculator. Yet type your problem out on the keypad, and the answer appears on a large white display mounted on the side of the monstrous brick structure. No spaceship can do that... can it?

"The screen and keypad were always meant to be the main feature of this machine," he writes on YouTube. "The main display boasts 25 digits. Square root signs are displayed and can change to accommodate any number of digits. Square root signs, add, minus, multiply and divide signs are displayed at appropriate times, and there is a full fraction display. The 7-segments for the fractions are the smallest possible, being only 3 wide, and stackable vertically and horizontally."

The video itself explains that its overall size is more than 5 million cubic meters -- just over 250 x 250 x 100 blocks. It provides 14 functions, BCD input, 2 BCD-to-binary decoders, 3 binary-to-BCD decoders, and 6 rapid BCD adders and subtractors. It also contains floor after floor of live decoders for quick conversions, a 20 bit (output) multiplier, 10 bit divider, a memory bank and additional circuitry for the graphing function.

    Fixme, but that's a generated "map", isn't it? (E.g. it is made with an external application.) I don't know. You can already see GPUs and other hardcore stuff. All of them are generated in the same principle, and it doesn't take too much work to do something like these.

    But a Minecraft addict may be able to give more info on this. (And these generated stuff.)

    This 16 year old is astonishingly brilliant, for his application to MIT all he needs to do is email a YouTube link. It's simply unbelievable that's all I can say.

    Is there a "Building a CPU in Minecraft" for dummies book? This stuff is interesting. It's like some really weird kind of ladder logic or something, stone & lava logic?

    There are people that have built working 8088's in the game.

    It's far more impressive if you don't use MCedit, though.

    All I can say is that when I was 16, school took up way too much time to even think of doing such a feat.

    Its not a graphing calculator, graphing implies it can visually graph functions, and it cant. It is a calculator tho.

    If he did it himself its impressive. However long before this ive seen people demonstrate all the pieces above. If he just took the work of others and pieced it together, then its still impressive, but its nothing extraordinary.

    IF he did everything himself, without the work of others, then im truly impressed.

    Its likely he took the adders etc from other peoples minecraft computers and stuck them together to make the above. And remember you dont do a project like this in the real game, you use an editor that allows you to slap things together orders of magnitude quicker.

    Still, given the anonymity the Internet provides, you can never be absolutely sure he IS sixteen years old!

    Can these working 8088s run older/lighter operating systems and software? This seems like a very cool thing to look into. Would be awesome to see something like DOS or something running inside of MC on one of these 8088. It would be so cool to play pong inside of MC.
