• Description:
In this video, I build a 5"x4" picture frame containing an e-Paper/e-Ink display controlled by an ESP8266. I program the ESP8266 to fetch data from reddit.com. Specifically, I fetch the top post of the day from the /r/showerthoughts subreddit. Instead of using reddit's API, I show how we can get the data by a simple query with some URL parameters. I also show how to scrape the site and parse the response manually, as it can be too large to store in a variable in the sketch.

nice one, kinda gave me lots of other ideas but there some questions for me: 1 - what makes it different than other tft displays? 2 - how big was your bitmap icon and what amount of memory did it need? 3 - how much energy does this kinda display consume? 4 - i was thinging to run it on battery and give the esp some other functionalities like deep sleep and so on to down the energy or using some energy harvest methods to use it for some of my projects

@@jblecoz well i did knew about it what i ment was the size it took not the formula like how much of flashsize did it allocate for the icon he made

Hey, Ali. Glad you liked it! 1 - good: ultra-low power, high contrast (closest to real paper). bad: slow refresh rate, 2 or 3 colors only. 2 - 400x300 8-bit bitmap; stored in a char array of 15000 elements, so literally 120,000 bits of memory. 3 - it only consumes during refresh. the image stays on display even if the board and/or screen lose power. if e-paper is used to its strengths-i.e., for displays that are updated relatively infrequently-it will use considerably less power than a same-sized TFT LCD! 4 - definitely a great addition to a battery-powered project, as long as you don't need information refreshing quickly on the screen

Can't get it to run. After connecting to WIFI, it doesn't seem to do anything. "getShowerthought" is never called.

Do you have version for ESP32 ?

@HamzaHajeir 4 года назад

Nice and neat as always :) Did you hear about ESPArto Framework for ESP8266 ? It would help a lot. I'd be happy by hearing your opinion about it ;)

@datasith 4 года назад

Hey, Hamza. Thanks for the kind comments, and for stopping by (as usual) to check out the video. I haven't heard of ESPArto, I'll give it a try over the next few weeks, and see about making a demo video. Thanks for the suggestion!

@@datasith Nice, I've been following author since a year ago. So I can help if any question. ;)
