ESP8266 2.9" e-paper MyBusyPrinter Enclosure (based on Badgy from sqfmi)

thingiverse

This is my new e-paper enclosure made with Badgy from sqfmi, an ESP8266 directly on an e-paper board. The price is good but the quality is very poor. I ordered seven Badgy for this project and one of them has a faulty board, one electronic component was broken without possibility of soldering it again, and the USB connector had fake contacts. The Sqfmi company just left the possibility to send it back for re-soldering it, Europe to USA to Europe, no replacement, no other solution for the customer...very bad after sales service...so be careful... Operation: A web server makes API calls to retrieve Google calendars from 3D printers. The various displays retrieve every ten seconds their own calendar on this server and display it. The display also retrieves the temperature close to the print head to see if the printer is printing. It can play the colors of the LEDs to inform that the printer is hot or printing, or make them blink to indicate that the slot is reserved but no printing is in progress. Here is the list of components used: 1 x Badgy from sqfmi 2 x JST micro connectors 1.25 The wiring of the output is as follows: Leds -> GPIO12 DS18b20 -> GPIO5 I have desoldered the battery support because I don't need it and it takes some space. LED 0 is alone, fixed above the screen as status LED. The following LEDs go through the JST microphone connector 1.25 from the bottom. The temperature sensor (Ds18b20) is attached to the microphone connector JST 1.25 from the top. For the software library, I used this one: https://github.com/ZinggJM/GxEPD Library documentation: https://forum.arduino.cc/index.php?topic=487007.msg3323227#msg3323227
