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.

Update: it’s still running a few days later:

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.

@Goldkin What exactly... happened? That seems a bigger spike than necessary for say, just writing extra input to the same hour...

@Taylor All of the old 1-2am information got written to the new 2am when clocks rolled back one hour, because that’s how this particular time series handled going back in time.
