I'm very impressed that you managed to create a nice DIY replica of our development kit. https://www.visionect.com/development_kits https://www.visionect.com/development_kits We do the same in our Visionect Platform - a server component streams images to a WiFi, 3G or ETH enabled E-Ink device. We do sizes from 6" (proper device in casing) to 32" (in color as well).

Super neat stuff, looks like you guys have a solution that fills a big gap (the big disconnect is that you have hardware hackers who don't build up the stack or high level devs who have things they want to build but don't want to bring up panels to do it). What's the refresh rate/interactivity/frame rate for your devices? Looks like you guys have lots of awesome options - are there videos of the devices in action or the dev environment? Are the high prices of devkits primarily driven by the panel cost or for other reasons?

    Really interesting product selection - obviously on the pricey end when the market here is looking for hacky project type prices, but an open version of Joan for people to get playing with your stack at that £299/$350 price point might work for feeding dev support further up the chain?

      We tried that previously, but it didn't work out. People that want a cheap version, still complained about the price and suggested a hacked Amazon Kindle as a viable alternative.

        Fair enough! Though if you ever did want to explore that again, I'd be interested in a more entry-level to prototype some signage ideas (email in profile).
