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, a esp8266 directly on e-paper board. The price is good but the quality is very poor. I ordered 7 badgy for this project and I have one of them with board quality, one of the 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--> USA-->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 diaries from 3d printers. The various displays retrieve every 10 seconds, their own calendar on this server and displays 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 on the contrary 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 desoldering the battery support because I don't need it and it take some place 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)
