Tinky Care is an eink dashboard for a Pimoroni Inky Impression that shows self care tweets and org-mode completed task counts for the past week. You can also set a pomodoro timer with a button push to stay on task and remember to take breaks!
Maryanne built a tiny Pomodoro timer with a Raspberry Pi Zero W, Pimoroni InkpHAT - 3 Color eInk Display, and a Pibow Zero W Case.
