Show HN: E-Paper Family 2 Day Calendar
Hi HN, I did this project over the Labor Day weekend.
My family runs off our shared Google Calendar. This project was to use a ESP32 and three-color e-ink display to create a wall-mounted daily updated calendar, weather and news dashboard for us to coordinate our lives.

- gabeiscoding 1y agoI sunk a lot of time trying to get perfect 1-bit font rendering running under Docker (Debian Linux), but could not get it match the precision of the Mac default Arial font rendering. I have a side-by-side rasterized image showing the difference here: https://github.com/gaberudy/epaper-calendar/blob/main/docs/font-and-rasterization.md https://github.com/gaberudy/epaper-calendar/blob/main/docs/f... Linux insists on doing some freetype font thickening, giving the output a random thick-line look. If anyone knows more tricks to disable this or influence the anti-alias font rendering behavior, let me know!
