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.
This is really great to see a working Babbage computer out of legos, its not as accurate as Babbage's design...but amazing none the less. Too bad Babbage didn't have legos when he was trying to get funding to build his computer! The lego PC mock ups are nice, but nothing compares to a real working mechanical lego computer :-P
You can tell I'm an aries because of my ram.
Here's real integration of LEGO and computing, the first rev was MIT's Brick, now this...

Computers.
Note also that ENIAC's inended design purpose was to produce ballistic firing tables for Army artillery during WWII.
The road to tyranny has always been paved with claims of necessity.
Here is a quote from the man himself which is amazingly still relevant!
"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?'
I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question."
Charles Babbage (1791-1871)

Bring on the links! A favorite of mine-- Cable camera rig.
I built a Lego Turing Machine using only 1x1 blocks.
has a nice large article in it about Lego, which basically states that "Lego will do for robotics what iPod has done for music".
Thats a pretty huge claim - Lego's were something I was interested in when I was 5-6 years old, putting together those $100 kits my parents would buy for me.
It also seems to me that the image of the company is what's going to detract attention from any serious accomplishments. It's kind of like Toys 'R' Us getting in to the nuclear power industry - nobody would really take it seriously, because of the brand name.
I think Lego should consider doing whatever they can to shake the "just for kids" image, possibly selling stuff through another company with a different name, in order to really get attention for what they're doing.
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?
One of the owners og Lego, the millionaire Kirk, has personally piped funds from him to Lego in an effort to ressurect the company. It seems like it's working, but Lego will probably end up with a loss in this fiscal year as it has the last 5 years.
Some older references opine that Babbage failed because the parts and the mechanical engineering of the day just weren't up to the job of building a calculating machine.
That was always questionable -- after all, England had high-precision chronometers the century before Babbage -- but if you can build a Difference Engine out of flexy plastic and gears designed for use in toys, then problems with brass are no excuse.
The other theory is that the Babbage projects failed because he kept making design changes during assembly.
Oh, and Wow. All bow to the new alpha nerd!
As I understand it, Denmark's other exports consist almost exclusively of lager and bacon.
I'm not entirely clear, then, on what a Muslim boycott of these products is supposed to achieve.
Real Daleks don't climb stairs - they level the building.
There are some nice add-ons for POV-Ray that generate Lego parts, so you can play with them in a virtual environment.
