So I spent more time than I care to admit this weekend trying to prep a Pwnagotchi platform (RPiZW and e-paper). The code (by @evilsocket) hasn’t been released yet, but I want to be ready. My mistake was only ordering one e-paper HAT from Waveshare. I should have taken failure rates into account. At least I’m 75% certain it’s a DOA unit. I tried numerous approaches based on numerous experiences by randos on the internet, and I couldn’t get that damned thing to display SQUAT. If it fed me back any data, it was just “e-paper busy.” Not helpful, Waveshare. Not helpful.
On the plus side, I was watching a video comparing different levels of USB microscopes for soldering (GreatScott!), and noticed that it was sponsored by JLCPCB, and they were offering a too-good-to-be-true deal on new PCB orders. So I went ahead and placed an order for ten MultiPass boards. Some of those will be up for grabs when they arrive. WAY cheaper than expected. I remain cautiously optimistic.
