A Turing Machine is something that you just think about, it isn’t a physical machine. Well now it is! Mike Davey has spent some time to create one.  Mike built his Turing Machine to look the part however inside you will fine a Parallax microcontroller as the heart.

“A Turing machine is a theoretical device that manipulates symbols contained on a strip of tape. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside of a computer.”
