#246 e-Ink e-Paper project with ESP32 Deep😴Sleep

An e-Ink / e-Paper project that is actually useful! ► JLCPCB Only $2 for PCB Prototype any colour https://jlcpcb.com/cyt More information in my GitHub for this project (including the code): https://github.com/RalphBacon/e-Ink-Reminder-Project 00:00 Welcome Back! 00:33 Sponsor Message 01:51 Project Details 18:16 End of main video 18:17 Where have I been then? 20:52 My PC specs (aspirational) So I finally found a project that suited the e-ink display I had from Adafruit very well. The display remains "on screen" even without any power being applied so the unit wakes up once a day, updates the display and goes back to sleep. During sleep it consumes about 27μA so the batteries should last for over a year. We shall see! The tricolour screen (that I'm using here) takes a whopping 15 seconds to refresh, but the monochrome displays take just 2 seconds, says Adafruit.
