For my part, I loved the long form, in-depth post, and I learned a lot. I'll admit breaking it up visually with some diagrams or photos is tempting (maybe a photo of your serial setup?) but I felt the explanations were all clear without it.
Ah, that's a good point. I actually need to port over a Hugo shortcode to handle little image boxes for this kind of thing; once I have that it probably makes sense to add a little photo of my setup as an aside, not so much as an explanation but rather for visual interest.
