Eight Position Optical Position Sensor

This assembly is designed to allow a MCU to get accurate angle and direction data using optical transistors.

I've revised the design several times, and the current one seems to work, but I'm still waiting on the optical components I ordered to arrive.

I will update when I have the finished prototype.

UPDATE: Based on a suggestion from Corona688, I designed a 3 bit binary version as well. I haven't tested it yet, but I will update when I do.
