The FriendlySTACK Reminder is a delightful DIY desktop gadget that transforms your emails into real-time digital sticky notes, turning the mundane flow of communication into something visual, interactive, and easy to track. Developed by tech tinkerer and designer Matt Webb, STACK is a compact e-paper display housed in a wood block enclosure, resembling a tiny digital billboard made for reminders.

The magic happens through a Gmail integration: when an email is labeled “STACK,” the subject line appears almost instantly on the display as a digital note. When the task is done, simply remove the label to clear the message from your device. Created with modularity and minimalism in mind, STACK runs on a Raspberry Pi Zero and Inky pHAT e-paper display, making it accessible for DIYers and productivity fans alike. It’s an elegant alternative to messy Post-its and clunky notifications, bringing a bit of charm to task tracking while maintaining a clean desktop aesthetic.
