As of now, the hardware design phase for this project is complete. I will continue working on adapting this project to my specific needs, and continue documenting my progress with that to use as an example. The remaining programming will be continued starting late next month, for reasons explained in a previous log.
I have posted the current hardware design and schematics to this project's github repository. You can also find this project's PCB shared on OSH Park too. Some basic, working, but incomplete example code will be uploaded once I clean it up. I would also like to thank OSH Park for featuring this project on their Twitter!
