Thanks, @kyle.anderson.

Conceptually it's not far off the Kindle. But, technically, it's a larger E Ink screen than the Kindle's.

We got to the point where we had prototype screen hardware from the E Ink corporation, but we couldn't find an engineer who was able to connect the components together on our budget... which was a few hundred dollars.

Also, there seemed to be technical hurdles even if cash wasn't an issue. Although the possibility of a DIY solution appears to be getting closer, based on the work of the indie hacker community: http://hackaday.com/2017/04/20/e-ink-display-driven-diy/

Awesome work! Love your involvement with the DIY community. Keep us updated on future prototypes.

Thanks for such a nice compliment, @kyle.anderson.

Will keep you updated :)
