A Universal Turing Machine In 100 Punchcards 48

New submitter theclockworkcomputer writes "100 years ago tomorrow, Alan Turing was born. To celebrate, I wrote a Universal Turing Machine in 100 Punchcards. I've uploaded a video to explain a small part of the read head (the Jacquard). One needle is shown out of a total of 28. As this is about a program for a Turing Machine and not about a Turing Machine itself, I hope to be excused from the requirement of infinite tape."

    I'm not sure if the plans are available anywhere but since (I think) it's built off a standard MindStorms LEGO set anyone should be able to recreate it.

    I understand, however, that LEGO will be unable to provide an infinite number of bricks that are needed for full implementation.

    He was hounded into dangerous therapies because of his sexual orientation. Now the largest computer company in the world is run by a gay man. What would Alan had given us with another 20 years?

      Please don't compare people who have actually done stuff like Alan Turing to management jobs that any idiot is qualified for.

      Wait a minute ... Balmer's gay?

    • Can the word "Turing" be mentioned in a Slashdot submission without some random guy bringing up his sexual orientation?

      Everyone knows the story, it has been denounced and publicly acknowledged and an official "I'm sorry" was told. I welcomed those events and moved on. The meme, alas, persists. Even Simon Wiesenthal said something like "We can't pretend there weren't deaths in the holocaust, but we can't think about it all the time".

      Now, can we talk about what's relevant? Like TFA?

        You must be new here ;}

        Realizing there is no chance anyone will read TFA, let alone discuss it, personally I would just be happy if the homophobes would crawl back under their rocks and let the important off topic discussions continue!

      One would hope nothing... didn't the guy deserve a lifelong vacation by that point?

    • What would Alan had given us with another 20 years?

      Hard to tell. In his latter years, he went wandering off down all kinds of intellectual paths. He might have produced great things, he might have produced mediocre things, he might have produced nothing of use at all.

  • I would be very interested in how you made what you made.

      I as well am very impressed and tip my hat in amazement. However, as I watched the video and then went to his page and started trying to understand how this would communicate with his mechanical bus, I couldn't help but wonder if he had consumed vast amounts of Cougar Boost [youtube.com].

    For who is interested here is a schematic [theclockworkcomputer.com] of the machine
    • I saw the youtube site. My first thought was what software was used to make the "mechanical" visual. Possibly Blender3D?
      • Hi. NX7.5 animation and motion (at work in the weekends). A 2001 version of Rhino to model and animate the leafs. Gimp to past the leafs into the animation. Inkscape to render the titles. Audacity to edit the sound. Blender to convert the stills to avi and add the sound.

    Wow. Regardless of the geek cred you get for making such a beast, let me commend you on the sheer artistic beauty of your website and the video. Just wow.

    I wish there was a way to add "Likes" to articles, this one deserves a +1 cool.
