A wearable PC using a Raspberry Pi and a Vufine as the display.
I wrote a little tool to view text files. It is written in my N language and runs on my Nano VM.
The text size is optimized for the view finder screen resolution. The tool uses automatic simple "line wrapping". The text can be scrolled up and down.
Here is a screen shot of the tool:
On the view finder the GUI is black and white. The used font is very good to read.
The Vufine + display plugs into the HDMI out of the Raspberry Pi. The picture is sharp. So this was a good upgrade.
I use a Ravpower power bank. It has a power LED display on it, so it is easy to see when it is time to charge! The power bank has one 2.4 A output for the Raspberry Pi and one 2.1 A output for the viewfinder.
I use Calibre for E-Book reading. I did install gcc/clang compilers, KDevelop, VLC video viewer, open office and others.
