One of the most recent Esquire magazine comes with an E-ink module, that proves itself useless after you read the magazine.
The guys at Hackaday went really far into hacking this E-ink module to use it as a clock. Now, that’s a good re-use, why waste technology?
If you’ve never heard about electronic paper, crawl out from under that rock and read up on the Sony Reader and the Amazon Kindle. E-paper is a flexible display made of color-changing beads that mimic ink-on-paper for easy daylight reading. The revolutionary thing about e-paper is that after it’s set, it stays that way without additional power.
