Check out termux so you can combine the native install with tools such as Git to have a fuller installation. org-roam seems to work. No native compilation but performance is still ok. Also turn on touch-screen-display-keyboard and touch-screen-precision-scroll.

Looking good 😎.

What do you use as a charging circuit and (grid tie?) inverter? I’m interested in affordable components and corresponding wiring.

Assuming you’ll draw less current than the iMiev does, you may be able to get more energy from the cells 🤞
