This is a simple text encoding machine designed and built with LEGO. It allows the encoding of any message with a simple pre-defined cipher code, and then converting it back to the original message.

The idea is that the left wheel is always the input, and the right wheel is always the output, so you always read left to right.

In ENCODE mode the wheels are lined up to give the simple pre-calculated cipher text mapping. Inputting clear-text on the left wheel, reveals the cipher-text on the right wheel.

Switching to DECODE mode spins the wheels to be 180 degrees out of phase. Due to careful mapping of the cipher code on the right wheel, this makes the left wheel the cipher-text input , and the right wheel the clear-text output.
