Now playing with e-ink displays. A few hours of soldering and staring at wiring charts later, I decided to be vain.
The goal of this experiment is to display some data graphs, but might as well have some fun with it first.

And we now have a solar-powered computer, tracking solar power and energy usage for the whole house.

For those interested in building their own, this is:
* One Raspberry Pi Zero W. I used the Vilros starter kit (~$35)
* One Waveshare 4.2 inch e-ink display ($10-40 depending on wholesale rates)
* One HI-S025 solar charger (~$40)
The thing is wireless and can do USB and HDMI too, which is just crazy.
