Nice project! I'm an electronics dummy so I went straight for the wake logic system, but I am so impressed with the DIY controllers you guys are coming up with. I didn't know what a esp32 is... is that essentially a different flavor of a Arduino / raspberry, etc.? I love how you made the ring light up around the side that's on. That's something I'd like to do to mine, since I have not found a good spot to put my wake logic LCD display, I want to make small LED indicator lights but will have to come up with a way since it uses a momentary (on) off (on) switch to control.
That e-paper display looks cool too! Well done all around.
