Your Own Turing Machine: Part II

Sunday, October 7th, 2007

Last time we built a Turing machine as a rainy-day project. Today, I’ll show you how to use it to do something useful, like add two numbers together. (more…)

Build a $2 Computer

Monday, October 1st, 2007

In 1936, Alan Turing conceived of a machine that helped lay the groundwork for modern computing. These extremely simple machines, dubbed Turing machines, are in theory able to simulate the logic of any known computer that can possibly be constructed. While Turing originally conceived of his machine only as a thought exercise and never constructed it, it is possible to build and program a simple version of Turing’s computer for only a few dollars worth of basic office supplies.

This is a fun afternoon project for all ages, and a great way to introduce both kids and adults to the fundamentals of computer programming.
