I saw this interesting project, is a laser galvo burner using two mirrors glued to 2 CD-ROM motors:
youTube - laser galvo positioning with magnetic incremental encoder
The sensor can produce "0.0036 deg / step". Unfortunately, the "AS5311" is a surface mount component, and my DIP tools and skills are too big to make a board for that component, and would actually have no way to solder that on anything I have.
I was wondering if anyone knew of a different component or device I could substitute with, that I can actually use to make a project like this, in a practical DIP size. I get really confused sorting through the 100,000 parts in mouser and digi-key.
If I made the project, I can possibly etch / raster the PCB print on a sensitized copper clad - to move into doing surface mount components. This machine also saves alot of bench space compared to a belt-driven gantry with many more moving parts.
