CRYPTOiNK

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.

Goals:

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 (https://cdn.hackaday.io/files/1799517699023584/Image2Lcd.zip)

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