YouTuber Paul Lagier has created the world's smallest e-reader, a device barely larger than a human thumb. This DIY project fits 6-10 books while maintaining portability that traditional e-readers lack. The specialized reading device focuses purely on text consumption without the distractions of smartphones, addressing growing demand for distraction-free reading experiences.

The tiny e-reader combines a 3D-printed shell with an ESP32 microcontroller and Heltec Wireless Paper display. Lagier documented the entire build process, sharing design files and assembly instructions. Unlike Android-based e-readers that try to replace smartphones, this device specializes in one purpose: reading. The creator has released an updated version with improved firmware.

For just €4.90, builders can access all necessary files and future updates. With component costs around $30, the total project costs roughly one-fifth of a basic Kindle. The device's optimized storage allows fitting more books despite the 8MB limitation, representing a practical solution for readers seeking ultra-portability.
