This is my proof of concept:
I want to create a status display for my classroom. The admin likes to know what the students are doing and where they are. They like that info to be posted outside each home room.
After mounting each eink display without the Kindle "wrapper", the final "poster" will be roughly 7x15 inches. There will be a 0.25 inch seam between each pair of Kindles. I have a lot of work to do to get there. This thread is where I will log my progress.
