Interesting. Do you know if anybody sells these e-ink (either
monochrome or colour) for use with a RaspberryPi? THAT would be very
interesting indeed. I have a 4" diagonal TFT colour touch screen with
480 x 320 res that I'll put on a RPi when I get a round tuit. I'm
planning to run XK8000 on that, but a colour or monochrome eInk touch
screen would most likely be more readable in the cockpit.

Check this out:

It's not completely what you're after, but it's getting there.

Agreed! This one is even better:

and this is better still, though not e-Ink:

dsi-lcd.htm

It is dual colour (black/red on white) and the size is pretty much ideal.
Ideally I'l find a screen thats almost the same size ad thr Medion (3.5"
screen but wide bezel (4.4" x 3.2" - 80 x 105mm) Its mounted on a flexi
mount in front of my panel. Anything bigger than that and I start to
loose sight of my radio and backup vario behind it. I fly a Libelle, so
having stuff mounted where it sticks out past the panel edge is not an
option.

However, to control LK8000 (or XCSoar) I could really do with a touch
screen. So far, the best screen I've seen is this:

Pimoroni HyperPixel - 4.0"
https://thepihut.com/collections/ras...cts/hyperpixel

.... I got one to experiment just before they went out of stock in early
March and AFAIK haven't yet reappeared, but that may be COVID rather than
lack of interest in making any more.

BTW both XCSoar and LK8000 have been ported to the RaspberryPi, which is
why I keep banging on about that hardware, and Pimoroni do some very nice
addons, such as a PSU board that supplies 5v regulated from a 1S LiPo
battery and can charge it from an external 5v supply while also driving
the Pi.
