Summary

Work-in-progress project to use a CD as an optical encoder for experiments. I'm writing some code for an AVR-based project to count up and down, depending on which way one spins the CD.

All parts designed in SketchUp.

These parts are fine-tuned for my Kossel printer, so they might not fit exactly.

To do:
Test assemble
Make a base
Make an LED/Photo transistor holder
Make pattern for CD

Kudos to HomoFaciens for inspiration
