CRYPTOiNK is a small 7in x 7in Display that pulls current Cryptocurrency Data from the web and displayed it on a low powered Trig-collored E-ink Display. With the evergrowing interest in Cryptocurrency CRYPTOiNK give the use importation information at a glance.

Periodically (10-30min) CRYPTOiNK's ESP8266 will wake up, Connect to local Wifi, and download up to dat Cryptocurrency data. It will then Display up to 7 Different Cryptocurrencies at a time. CRYPTOiNK takes advantage of the Trig colored E-ink displays and will hilt the currency in Red if the 24-hour Price is Down. This allows easy differentiation of currencies "in the black or in the red".

CRYPOiNK is fully Customizable and a tutorial is provided on how to add or change the Crypto's that are displayed.

    I assemble and painted the Housing to be more appealing and to hid the 3d print layer lines

    I designed this housing to Secure the CRYPTOiNK Hardware to any Refrigerator.  I uses 2 long magnets to secure it to most steel doors and has suction cups if the door is non-magnetic.

    CRYPTOiNK uses a TP4056 Charger to charge a 6000mAh Lipo Battery.   Built into the Charger is a Low Voltage, Over Voltage, and Over Current Protection Circuit. 

    Because the Ilpo battery does not provide a constant voltage and ranges from 3.4 -  4.2V, a MT3608 DC/DC Boost Module to provide a consistent Voltage for the Waveshare Driver board to regulate down to a 3.3V that is used by the ESP8266 and Eink Display.

    1) A Low Powered E-Paper Display

    2) Graphically Display Cryptocurrency Data

    3) Attach to a Refrigerator or Door (Magnets and Suction Cups)

    4) Update on a 10min Basis

    5) Visible 6-12Ft

    //----------------------Extended Goals----------------------

    5) Encoder wheel + OLED to input SSID and Passoword

    6) Buttons that, when pressed, go into details of each Cryptocurrency

    //-----------------Estimated BOM-------------------

    The Standard hardware for this Project are:

    1)  1x     Waveshare Esp8266 E paper Driver

    2) 1x     Waveshare 7.5" B/W/R E paper (640x384)

    3) 7x     12mm Tactile Buttons

    4) 1x      Encoder (For Wifi Setup)

    5) 1x     OLED Display (For Wifi Setup)


    I Started out using the GxEPD2 Library to create the format

    I Used Kevin Darrah's E-paper Tutorial on how to crate graphics for the E-Paper Display using the tool Image 2 LCD (

    Using this Tutorial I was able to produce a format that can be seen from 6-12ft Away

    Creating API using ThingSpeak (Example TRON)

    Sign up and Register your ThingSpeak Account

    Once Registered open the ThingHTTP under the APPs

    Then Create a new ThingHTTP

    Now the 4 Things we need to input are the NAME, URL, HTTP Version, and Parse String

    NAME:   TRON_Price


    HTTP: 1.0

    Parse String :

    Now Choose a Reliable Crypto Exchange you would like to pull Data From  I Suggest CoinMarketCAP
