Wow, that's beautifully doneThis YouBoob video of a working model using 35mm film, an erasable pen, a felt erasing wheel, a digital camera, some servos and stepper motors, and a microcontroller shows exactly how a Turing machine works: http://www.youtube.com/watch?v=E3keLeMwfHY
Probably worth linking to http://www.raspberrypi.org/archives/1146 againObviously, we need to build one run by a Pi ...
That's because it wasn't his birthday till today . So happy birthday Alan! The word "genius" seems to be used pretty lightly these days but Turing was a true genius and a very modest chap by all accounts.Jim Manley wrote:I'm surprised that none of the Brits mentioned this, so, leave it to a Yank to bring it up
Nowt to do with Google - most people I know (myself included) who have close friends and relatives who are dead raise a glass to them on the day that they were born. If you have to pick an anniversary to celebrate the life of someone, the day of their birth is the most logical one to pick (as opposed to, say, the day that their balls dropped or the day they passed their driving test).Lorian wrote:...

Well, we're waiting ... where is your discrete electronics or mechanical version? A microcontroller uses solid-state electronics, BTW - you probably meant discrete electronics (individual components). Solid-state refers to the fact that the components use crystalline semiconductor materials, instead of inert gas-filled or evacuated components (i.e., vacuum tubes or, as our UK cousins say, "valves").Joefish wrote:A great centenary, but there's always something bugging me about people building their own 'Turing Machines' that need a microcontroller to operate them. Surely the point is to do it with solid-state electronics or a mechanical system? Requiring a CPU and RAM to demonstrate the fundamental principles of the most basic processing device imaginable seems to me to miss the point by quite a wide mark!
