Designed and printed a case in Fusion and added telemetry and OTA updates with Blynk!!! You can check out the [code](github.com/UnsignedArduino/ESP32-7in-EPaper-Weather-Station) and [hardware](github.com/UnsignedArduino/ESP32-7in-EPaper-Weather-Station-Hardware) if you wish.

I spent way too long trying to generate the QR code from the auto-generated SSID and password to display for WiFi provisioning lol.

Added some icons to be more "user friendly" today. Since I don't have a drop of creativity in me they were taken from Bootstrap Icons lol.

Not much change today, but I reworked the battery gauging system so that the percentages don't wildly vary - DSP is hard.

I fixed some character rendering errors and optimized battery usage today, dropping the deep sleep current from 628 microamps to 31 microamps.

Added battery support to my E-Paper Weather Station - now to see how long it lasts!

Hacked together a small power profiler from an INA260 to measure power usage of my E-Paper weather station.

Today I worked on deep sleep (which was particularly annoying and fussy for some reason - it will run on batteries eventually) and polishing the rest of the main display. Code here

Worked on adding another language to my E-Paper Weather Station by using custom fonts. Code here if interested - more documentation coming soon. (tm)

Started working on an E-paper weather station. Uses a Firebeetle ESP32 (good for low power usage) and a Waveshare 7.5in BW E-Paper display. So far, basic WiFi provisioning and a basic display works. Code here.
