I've been diving into digital communications, particularly VLC (https://en.m.wikipedia.org/wiki/Visible_light_communication https://en.m.wikipedia.org/wiki/Visible_light_communication) There is some decent information out there about it including open source solutions and many good papers (unfortunately some paywalled) and I've been working on a very primitive prototype, but I've been pretty distracted. I've also ordered some books on VLC, digital communications that cover theory as well as some more applied ones. I do hate how many of the books are either textbooks or associated with standards that seem to make them very expensive. Unfortunately sooner or later, I'll have to face my extremely weak math ability, which I'm dreading. Behind that I have a ton of side projects backlogged ranging from more digital communications and hardware stuff, to retrocomputing projects, to some ML stuff I want to try.
