A 32 bit Galois Linear Feedback Shift Register pattern creates a barcode like pattern for a TT motor encoder. The usual encoder disk has 20 evenly spaced slots. This has 16 slots. However, the spokes and slots vary in width creating a bar code. This lets software figure out absolute position and direction of rotation using only one sensor.
The openscad file is included if you want to modify dimensions.
