[Quoth]

So the quoted 1.5 second refresh for ACeP is optimism? That's a sad speed.

I've got lazy, so I now mostly buy ready to go gadgets. The 4.7″ elongated eink is cute, but I don't think there is anything to customise unless it might be a different case. It all comes apart easily. I've a 7.8″ Android eink gathering dust.

I bought a 15″ approx USB powered QHD screen for my Pi (but it has no touch). Has nearly matt screeen and works via HDMI or USB-C DP Alt. I use it more with my laptop as it's better than the builtin 17″ and sits on top. There are touch screen battery powered monitors but most don't seem very good.

I toyed with idea of a BT module in the serial port inside my DXG (I have the module), or custom SW on an original Aura H2O as it has an SD slot, but the IR touch is poor. Maybe I could do something interesting with the Boyue Likebook Mars (7.8″ android eink with SD card slot and WiFi and real headphone socket).
