What is it?

  • Electrophoretic displays use charged particles suspended in microcapsules to form an image.
    • Reflective: They use ambient light like paper
    • Bistable: Once an image is drawn, it stays without power
    • Low refresh rates, but extremely low power draw.
    • Monochrome, grayscale, and color variants.
  • Ideal for: reading, writing, and environments with natural light

Caster is an open-hardware

  • High-refresh electrophoretic display controller that  supports multiple EPD screens (B/W and color) and supports multiple refresh modes:
    • Partial refresh for fast updates with minimal flicker
    • Grayscale for image fidelity
    • Full refresh to clear ghosting when needed
    • Fast mono for high-speed UI feedback

Who needs this?

  • People seeking a balanced digital life
    • Want to reduce screen time, avoid overstimulation, and reconnect with the physical world.
  • Those with health sensitivities
    • Suffering from migraines, light sensitivity, eye strain, epilepsy, or other screen-related conditions.​
  • Designers and technologists
    • Seeking to build humane tools—devices that protect our well-being.

What becomes possible?

  • A new category of devices and user experiences:
    • Computing devices that feel native on e-ink—no flicker, no redraws.
    • Calm computing environments that support focus, reflection, and slower thinking.
    • Minimalist tools for writers, developers, readers, and researchers.
