Turn an old Kindle into a local e-ink side display
Kindle Side Card transforms old or jailbroken Kindles into dedicated, glanceable e-ink side displays, making it ideal for users seeking a minimalist, low-power dashboard. By leveraging open-source software, it creates a local-first, privacy-focused solution that renders status updates or information snapshots in a Kindle-native format. The tool employs a Python daemon to generate PNG images, which are then displayed on the Kindle via Wi-Fi, providing a seamless and distraction-free experience. Unlike conventional dashboards or smart displays, Kindle Side Card emphasizes simplicity and energy efficiency, making it perfect for monitoring weather, calendars, or server statuses at a glance. Its open-source nature encourages customization and community-driven improvements, appealing to tech-savvy enthusiasts and productivity seekers alike.
