Dual-Screen E-Ink Tablet

Team: Callie Kubesh and Ethan Wayland

Project

  • Standard e-ink tablets are great for note taking, but they lack fundamental multi-tasking capabilities.
  • Many smart LCD tablets have superior multi-tasking functionality, but can be expensive, large, and consume a lot of power.
  • The Dual-Screen E-Ink Tablet is an e-ink device with two screens designed for multi-tasking. The user can reference a PDF on one screen while taking notes on the other.
  • The secondary screen is detachable from the primary screen, allowing for more versatility and multi-tasking options.

Methods

  • Raspberry Pi 0 2 W used as primary processor
  • Two e-ink screens integrated with two touch screen digitizers
  • Tablet Physical Interface connects the two screens together
    • Attachment/Detachment mechanism
    • Electrical connection through pogo

Conclusion

  • Capable of competent multi-tasking such as annotating a PDF while having another PDF on the other screen.
  • The secondary tablet is capable of fully detaching from the primary tablet
  • User interface is minimalist and simple, but it could be built upon to add even more functionality
