EinkScreen

Introduction

An e-ink display card that mirrors your phone screen, to help with reading documents, e-books, web pages etc!

The project is made to be as cheap as possible, coming to a total cost of around $35USD for materials. This would be even lower if made/bought in bulk!

As this is a prototype and in heavy development, I would not recommend making this unless you're willing to tinker/is familiar with electronics and or app dev. Nevertheless, If you do want to make the project you are free to do so! I am open to answering any questions should you make the card. I am also open to the idea of making and selling the hardware itself, though this comes down to if there is interest in the project and when I feel the quality is good enough.

Currently, there is only support for an android app. Check out the repo here. I have no experience in IOS development, so I am entirely unsure if an app can even be made for the IOS system. If it is, do let me know!

Any suggestions and support is greatly welcomed.

Notes when building

1. Use a 11uH receiver coil and connect to AC1 and AC2. feel free to use a different coil if you so wish, with C32-C34 and C15 for tuning. refer to BQ51013 datasheet for more info
2. Bridge both JP1 and JP3 from the middle to pad 3, these help select options for the e-paper driver
3. Adjust/remake the CoilLifter.stl to fit your receiver coil size

Future

Although the project was primarily built to be as cheap as possible so to allow anybody to get an e-reader, a future version with touch screen and battery is being considered! This version would likely add significant amounts to the cost, but would likely make the project infinitely better. Additional features like auto/partial screen refreshes, manual cropping, custom button functions are also being considered.
