LEGO Tech Still Going Strong

zimage writes to tell us that Andrew Carol has designed and built a working Babbage Difference Engine out of LEGO. From the article: "Before the day of computers and pocket calculators, all mathematics was done by hand. Great effort was expended to compose trigonometric and logarithmic tables for navigation, scientific investigation, and engineering purposes. In the mid-19th century, people began to design machines to automate this error prone process. Many machines of various designs were eventually built. The most famous of these machines is the Babbage Difference Engine. [...] Babbage's design could evaluate 7th order polynomials to 31 digits of accuracy. I set out to build a working Difference Engine using LEGO parts which could compute 2nd or 3rd order polynomials to 3 or 4 digits." In related, but not quite as functional, news DigitalDame2 writes to tell us that PC Magazine has an interview with LEGO "brick-artist" Nathan Sawaya, creator of their commissioned LEGO PC. There are also several pictures of the creation in addition to a contest to win the snap-together sculpture.

      Well, the design made out of Legos is far far simpler than Babbages machine, so obviously easier to produce. Difference Engine 2 was supposed to calculate 7th order polynomials to 31 digits of accuracy. The lego contraption can only calculate 2nd or 3rd order polynomials to 3 or 4 digits of accuracy.

      Had Babbage been interested in actually producing these machines rather than designing them and finding out what's possible I'd bet he would have done something like this machine first as a "proof of concept", and then sought more funding. After all, if you can make this thing out of legos I'm sure it'd be fairly trivial to make it out of metal gears. Babbage was a mathematician though and not a business man or engineer so he wasn't really that interested in actually making the thing.

      It makes you wonder what would have happened had someone figured out a business use for Babbages machine, and made some kind of deal with him to design a more practical calculating device. I think that's even the subject of a sci-fi book called "The Difference Engine".

    Lego is not going strong. As a matter of fact they're going through their worst crisis ever. Recently, they sold off their theme park "Lego Land" to a capital fund. Their problems are mainly decreasing sales due to illegal copies manufactured in Asia, but also similar toys manufactured in Asia. So, Lego faces a challenge. The danish factories are very effective and produce high quality, but the pay is many times higher than if they outsource. Yet, they core of Lego is their headquarters in Billund, Denmark. If they move everything to the east, would it still be Lego?

      You seen any recent Lego kits?

      10 years ago, your average Technic kit consisted of a few hundred brightly-coloured blocks which were fairly generic, maybe one or two unusual pieces, and they all fitted together in more-or-less the same way. You could even fit them to traditional lego bricks.

      I was given two kits for Christmas 2004. The first consisted entirely of beams which were smooth top and bottom and had to be fitted together with axles. Not very useful in conjunction with the old parts. The second consisted of bricks in about 6 or 7 different colours, all similar shades, and almost impossible to tell one shade from another in the printed instructions. None of the colours were the traditional Lego bright primary colours. Which was a bit of a bugger if you wanted to build the robot the included instructions covered as the whole look was ruined if you got the colours wrong.

      I later discovered that these two kits were close to the top of the Technic range and the range itself had narrowed to no more than about half a dozen or so kits available in your average toyshop.

      The chronometers were individually hand-crafted masterpieces.

That led to factories where the money someone was paid was based on the time it took, rather than the skill of the operator or the complexity of the product. The Difference Engine/Babbage helped create the Industrial Revolution, and benefitted from it.

      I think the real deal is that Babbage was a mathematician, and not an engineer. He was far more interested in what was possible to do rather than actually doing it. He designed the difference engine and made some progress on actually creating it. It seems like after he decided it was possible he went right on into designing a far more advanced computer, the analytical engine. The analytical engine was far more advanced, and was actually turing complete. That means that given enough memory and time, it could perform any calculations that a modern computer could produce. Even though Babbage never made the analytical engine, many of the concept he created are all a part of modern computers.

    I was kind of a neat concept, but honestly I found that arranging bricks via the mouse was considerably more difficult and less intuitive than putting them together by hand. One of the program's features, IIRC, was that you could put together a model in VR and then it would print a parts list for you. I suppose on very complex models that might have been useful, but I always felt like it would be easier to build the model by hand, take some Polaroids, and then take it apart to get the parts list.

    Anyway, it was a neat little program anyway, usefulness to 'Lego designers' nonwithstanding. It was fun if you were on a plane or something and just wanted to have a game to play that wasn't competitive but wasn't as ass-achingly boring as four hours worth of Minesweeper.
