e-ink seems to be the last bastion of reflective screens so i hope some day i can get a nice e-ink monitor or laptop screen (ha, good luck getting that for a laptop that isn't trash)

@wyatt I built my own using the 7.5in display from #Waveshare. It’s pretty great. Here it is in the sunlight.

@jrsharp how much did the panel and driving hardware cost?

@wyatt ~50USD. The display comes with a Pi Hat-style board. I’m interfacing with an ESP32, but should be fairly trivial with a Pi.

@jrsharp i hate pi's so that's a shame
i was hoping for something i could just use as a monitor via DVI or something (something with a refresh rate faster than my old kindle)

@wyatt ack. To be clear, the “hat” board breaks out the I/O, but it’s SPI, so nothing quite so convenient for systems outputting signals like DVI. In order to get the quick refresh at the panel level, I’m having to use custom LUT definitions for abbreviated refresh cycles. But even then, getting “quick” refresh is far from trivial — or universal to all use modes.

@jrsharp i guess i'd be having to do deltas/diffs of frames to determine what needs redrawn and it'd probably get rather complicated
