An "e-ink typewriter" that can only do one thing
Lucian's SPUDwriter (Single Purpose User Device) was designed to help him focus on creative writing after a long day of staring at a screen in his engineering job: it uses an e-ink screen and a keyboard, and only outputs via SD card or thermal printer.
As a person who does all of their engineering work on or adjacent to a computer, the idea of coming home and spending even MORE time on the computer for creative writing isn't super appealing. So I made an e-paper typewriter - no browser, no games, just you and your word count. It has a character LCD at the bottom for the current line you're typing, to make up for how slow E-paper updates, and when you're finished you can save your file to an SD card or print it all out with the internal thermal receipt printer for redline editing. I call it the SPUDwrite (Single Purpose User Device), hopefully the first of a couple of SPUDs. It's built on MBED and the STM32F401 Cortex M4.
