Richard J. Ridel's all-wooden, mechanical Turing machine uses the smallest set of data elements capable of computing any calculation: 0, 1 and blank; it was inspired by Ridel's viewing of The Imitation Game.
There are a number of issues that need mentioning.
I did not build a safeguard into the Writing Wires. Things will break if the machine attempts to write a ‘0’ as well as a ‘1’. And wires can migrate and drift.
The Reader Rocker basically floats when reading a ‘0’. It could move and present the wrong data to the back of the Configuration Mechanism.
Build the machine so timing and throw are adjustable.
Build the machine so you can remove a part without having to completely dismantle the entire thing.
My part names are not the most logical nor clear.
My engineering technique is not the best, however, efficiency and simplicity can be ignored for artistic aesthetics.
In the end, I had fun building it. And I guess that’s all that matters.
