The tiniest e-reader in the world, and you can build one yourself

4 hours ago

A YouTuber built a DIY, pocket-sized e-reader using a 3D-printed shell, an ESP32 microcontroller, and a Heltec Wireless Paper display.
The device is about the size of a car key fob, can hold 6-10 text-format books, and costs around $30 to build plus $5.80 for design files.
It focuses solely on reading without distractions, featuring firmware updates for better visibility, power efficiency, folder organization, and custom screensavers.
The creator provides all necessary files and instructions for others to build their own, positioning it as an affordable alternative to traditional e-readers like the Kindle.
