Steampunk Cyberdeck with eInk display

I measured the power draw of the eink Display. It is 1.5 Watts for text-based applications and 2.5 Watts for video in dither mode.

The cat image is an jpeg file that gets displayed on the display after the device is powered off and stays there until it is powered on again.

I'll publish the script when I get it to be a bit more reliable
