Ready to build your own? I just posted a wealth of IP to Github, ready for you to purchase some PCBs and match my results. I build the PCBs in Kicad, but I've also included Gerbers and a PDF Schematic for you non-Kicaders.

At this point the project matches the results of some of the projects I mentioned in this log. The board in the picture is an ESP32, which has enough pins to drive the 6" ePaper display without shift registers.

I will continue to improve the software on the ESP32 and make it do some funky web tricks - so even if the rest of the project is a dud we'll have a product.

In parallel, I sent the first draft of the conversion board off to @oshpark, who generously sent me a coupon. With some luck and a lot of VHDL and C, I'll be able to take VGA in at 800x600. I'll then have the board grab a frame and convert it to something the ePaper Display can read, then pump it out to the screen. If all goes well, we'll perform that symphony up to (it'll be an option) roughly 1x a second or so.
