Turing Machine - Read and Write test

One of my ongoing builds is for a Turing Machine, this is a hypothetical machine thought up by Alan Turing in 1936. The basic idea was for a computing machine. He surmised that if you had a piece of tape of infinite length and that tape could move back and forth against a head that can read or write a symbol on to the tape. There was then a set of states that determined what the head or tape should do, for instance if the head read a 3, the associated state then instructs the tape to move one position to the left and subtract 1 from the value. Another state could say if the head reads a 2 and the program step is greater than 10 then subtract one from the current value at the head. Depending on the length of tape, the amount of states and the time given, the machine could work out any computable problem. There is a lot of subject matter regarding Turing Machines, so enough background.
The machine I'm building works on a similar idea, however the tape is represented by 32 'cells' and instead of the tape moving there is a head that can go back and forth reading and writing to any position within the array of cells.
So far I'm about 10 months into the design and build, and in the clip I'm testing the communication between the head and the cells. It uses infra-red to read and write, so the devices need to be perfectly aligned to get good communication. On power up, the program instructs the head to write a random numbed to each cell ( the cell lights up white to indicate a 'write' instruction ) then on the return, the head reads whatever is in the cell and displays it on the head.

More video's as the build progresses!
Thank you for watching.
