An eInk dev board tracks fetal development @8iterations @hackaday

This fetal development tracker was put together by mokas using Adafruit’s ESP32-S2 powered MagTag. As the name implies, the all-in-one electronic ink development board is designed so that it can be adhered to a metallic surface with integrated magnets. The idea is that you can pop a battery in the low-power device, stick it on your refrigerator, and have a regularly updated display of…well, whatever you want.

In this case, mokas has combined a CircuitPython routine for displaying a progress bar with some example code that works its way through a slideshow of bitmaps. The fetal development images were pulled from Wikimedia, and a one-line ImageMagick incantation got them properly dithered for display on the e-ink panel.
